Water & Air Treatment

Important Tips While Choosing Different Types of Water Purifiers and Air Purifiers

Why is it emphasized the necessity to use a water purifier at home and work today?

Because of the growing population and the increasing industrial and human pollution in water and soil, the quality and health of the water have dropped even in cities that used to be healthy in the past. Infiltration and increasing the contamination in the water, especially nitrate of human wastewater to the layers of groundwater and water resources are very dangerous and can increase the risk of various diseases.

Prior to providing explanations about the types of home water purifiers and related filters, we inform you of the provision of a variety of valid home water purification devices with a guarantee of goods originality from 2004 by DamaTajhiz Company.

what pollutants are found in plumbing water?

Currently, some of the available water sources contain many pollutants such as industrial and home sewage, mud, parasites, bacteria, pathogenic microorganisms, and others that are very harmful to human health, not removed completely during the process of urban water purification; Therefore, in order to completely eliminate chemical solvents in water and suspended matter (germs, bacteria, etc.), heavy metals, as well as complete removal of nitrate and water hardness adjustment in the range of meeting the needs of drinking water, home water purifier equipped with membrane filters, fiber filters, etc. are used.

Home water purification systems not only completely eliminate water contaminants, but also use filtration and useful ions for the body (which we will discuss in more detail below) to provide healthy, light and clean water. You can ensure the health of yourself and your family by drinking and using these systems for such uses as cooking.

What is the most dangerous cancer factor in the water?

One of the most dangerous substances in water is a nitrate, which is one of the main carcinogenic factors, especially for stomach cancer. Therefore, a method called reverse osmosis is used to remove nitrate in water. In fact, the reverse osmosis system consists of membranes that have holes with very small nanoscale dimensions that only water molecules can pass through, and particles that are larger than water molecules cannot be passed. Home water purifier devices with reverse osmosis technology, eliminating impurities and water hardness, provide healthy, lightweight, and soft water.

Important points about the necessity of using a home water purifier include:

• In urban water treatment plants, nitrate, which is one of the most dangerous pollutants in the water, is not eliminated in any way, and it is needed to remove it with a water purifier equipped with advanced filtering.
  
  
• In urban refineries, chlorine added to eliminate bacteria and disinfect water is directly linked to many cancers, fetal abnormalities, heart disease, and asthma, as well as the carcass of microorganisms killed by chlorination, remain in water which is the source of another pollution in the water.
  
  
• Usually, refined water from urban wastewater treatment plants runs through rusty and old kilometers of pipes, which contaminates refined water.
  
  
• As chlorine gas is harmful to the human lungs in the pool or bath and also the contact of chlorine with skin and hair causes hair loss and damage to the skin, it is recommended that the chlorine in the urban water supply system is completely removed by home water purification devices.
  
  
• In order to maintain long-term water quality in mineral water bottles, preservatives such as fluoride in water are used in these bottles, which is a chemical agent and its continued use is also hazardous.
  
  
• Be sure to note that boiling water does not eliminate the microbial contamination in the water and does not eliminate the impurities and hardness solved in the water, but more boiling water increases the number of salts and nitrates present in it. This matter itself causes many diseases, so despite the fact that there is a very wrong belief among people, boiling water does not improve the quality and purification of water. According to the above conditions, we can say that today one of the essential requirements of life is the use of a device to ensure the provision of high-quality water to us and our beloved ones, so there's no choice but to use a valid water purifier.

 Comparison of mineral water and water purifier:

Salts

Salts and compounds in mineral water are deposited in the body after successive use and cause diseases such as kidney stones and etc.

Preservatives

Mineral water companies half a milligram of fluoride to one liter of mineral water, which is a flavorless and odorless preservative, and is carcinogenic and extremely dangerous to the human body. When fluoride enters the body's tissues, it occupies the tissue's environment and causes Inter-tissue water to escape. The body automatically creates a slippery layer that grows over time, which is called water retention. The outlet water of the water purifier is free of preservatives and is perfectly suitable for the body.

Storage condition

Mineral water is supplied in plastic packaging that has special storage conditions. For example, mineral water packages should not be exposed to direct sunlight, plastic packs of mineral water release the polymeric material in the sun that dissolves in water, and polymer materials are very dangerous to the health and carcinogenic. The water purifier does not add any polymeric materials to the water.

Economic efficiency

Using home water purifiers at homes and apartments provides you with healthy and light water, which is economically and qualitatively viable compared to mineral water bottles.

If a family buys a water purifier, the cost of this device is less than the bottles which are bought during some months and will be compensated.

In fact, spending to buy a water purifier is very intelligent work.

Helping nature

Daily use of mineral water bottles is extremely damaging the nature. We humans should not over-use plastic materials to help have a more beautiful and cleaner planet.

Advantages of 6-step water purifier:

Water Transparency and clarity:

One of the most interesting and touchable cases after the installation and operation of a home water purifier is using the water to provide tea or coffee, which will provide the best taste for the preparation of tea, coffee, food, and you will enjoy it.

Affordable water purifier device

Recently, water purifiers have been imported into the market that is not well-suited and do not meet the standards required to completely eliminate pollution and harmful substances in the water, but due to the good prices, they may attract some customers.

But, the fact is that the water purifier is related to human health and you have invested for yourself and your family by the cost you pay for it.

To achieve clean, clear, and refined water, the water purifier should have at least 5 main membrane filters, fiber filters, active carbon filters, salts filters, etc.

Selection and operation of water purifier:

• One of the points that are usually considered by the buyers of home water purifiers is the volume or capacity of the water reservoir of the water purifier. It should be noted that, firstly, the volume of the reservoir of the device has no relation to the ability of the device, and secondly the volume of the tank of the home water purifier should be just fit the amount of family consumption. (For example, the volume of water needed for a small family, which consumes about 3 to 5 liters daily, will be up to 6 liters to use the reservoir water at least once a day, and be replaced by freshwater as soon as possible.) It is also evident that using larger tanks is appropriate for more uses.
  
  
• The home water purifier requires regular and persistent maintenance to keep its function. Among other things, it is important to maintain the proper functioning of a variety of home water purifiers is changing cartridge filters, reverse osmosis membranes, and other possible causes in the manual of the water purification devices.
  
  
• In order to select a suitable water purifier, checking items such as the size and dimensions of the device, the location of the installation of the home water purifier (under the kitchen sink, on the wall, kitchen counter, etc.), the duration of the replacement or washing of the filter, the installation and replacement cost of the filter, warranty terms and after-sales service of the water purifier and etc. are recommended.
  
  
• The replacement times of filters for water purification devices differ because of the type of water hardness in different regions of the country, which the necessary explanations regarding the time and how to change the filter is provided by the installer to the customer at the time of installation.
  
  
• Buying a high-quality water purifier guarantees your health, and the cost you pay for it is actually your investment for the health of your family. Today, due to the presence of various microbial and chemical contaminants in water, using the water purifier is not a choice, but one of the requirements for family health. By purchasing cheap and inexpensive water purifier devices, do not throw away money and, with the right choice, install the appropriate water purifier at home and be comfortable with the cost you paid, as well as the after-sales service.

Number and types of standard water purifier filters:

The number of filters installed in the home water purifier devices alone does not represent the high quality of water output from the water purifier. In addition to the number and purification process, the type of filter and the technology used in them is also important in improving the quality of output water from the device. (Be careful about the originality of the home water purifier filter, which affects both the quality and the price of the device, and the quality of the water used is not worth the low cost of some home water purifying devices that are practically inefficient).

Filters used in the water purifier include:

• Polypropylene filter: To remove all deposits, sand, mud, corrosion of pipes, sludge, and suspended particles up to 5 microns in diameter, which have the same function as a sand filter and absorbs visible contamination in the water.
  
  
• Powder Carbon Filter: To remove chlorine, agricultural toxins, trihalomethanes, and most of the organic chemicals found in insecticides and pesticides, and remove the color and taste, and smell of water.
  
  
• Carbon black filter: to remove the highest levels of chlorine and toxic substances.
  
  
• Membrane: Removes 98% of harmful salts, including microbial contaminants, nitrates and nitrite, and heavy metals. 
  
  
• Linear carbon filter improves the taste and smell of water when stored for long periods of time in the reservoir.
  
  
• Bio-ceramic filter: To adjust PH and improve the taste and flavor of the water. 
  
  
• UV lamp: Ray diffraction method (UV) using a UV lamp to disinfect, sterilize the water, and all the microorganisms. 
  
  
• Alkaline filter: To raise the PH of the water.
  
  
• Mineral Filter: adding minerals required by the body after complete water purification for water softening.
  
  

General explanations about the mechanism of operation of the water purifier and the changes that it creates:

Purification phases in a 6-phases domestic water purifier are as follows:

The water purification steps by the 6-step home water purifier are as follows:

• Step one: At this step, mud, sand, and other detritus in water are removed from the water by a 5-micron fiber filter.
  
  
• Step two: At this step, the active carbon filter embedded in the water purifier device is responsible for the removal of gases and chemicals in pesticides and insecticides.
  
  
• Step three: The active 1-micron carbon filter purifies the water by removing chlorine and materials larger than one micron if it passes through the two previous filters.
  
  
• Step four: Membrane filter (RO), which is essentially the main filter of the water purifier, is composed of several layers of the semipermeable membrane formed by a central tube. It refines all soluble salts (nitrate, lead, calcium, etc.) between 80 Up to 98%. The filter has the ability to remove harmful minerals to a size of one-thousandth of a micron (organic and inorganic substances dissolved in water and microbial contaminants) as well as the ability to eliminate water hardness. 
  
  
• Step five: At this step, the odor and taste of the water that may be taken after a while in the reservoir are destroyed.
  
  
• Step Six: The UV filter embedded in this step, is responsible for the microbial decontamination of the water by infusing the ultraviolet rays into the water.
  
  

What is reverse osmosis?

In fact, the main filter is the reverse osmosis filter in a water purifier. The reverse osmosis filter consists of several layers of semi-permeable membranes that are wrapped around a central tube. This membrane has a pore size of one-tenth of a nanometer (0.0001 microns). Because water-soluble impurities are not able to penetrate the pores of this membrane, there will be pure water on one side of the membrane. It enters the central tube and leads to the outlet of the treated water. On the other side of the membrane layers, there will be impure water directed to the sewage duct. By reverse osmosis, microbial and chemical contamination is reduced by 90 to 98 percent. Nitrate, arsenic, lead, mercury, and other water-soluble impurities, and harmful heavy metals in water are removed at this step.

The factors affecting the performance of the reverse osmosis system are:

• Inlet water pressure
• Water temperature
• Type and amount of total dissolved solids (TDS) in tap water
• The quality of the filters and membranes used in the RO system
• It should also be noted that the reverse osmosis membrane filter can remove impurities and particles larger than 0.001 microns.
  
  

What is TDS?

All of the impurities in the water (TDS) are called Total Dissolved Solids, which its measurement unit is ppm. More ppm of water more water salt or more contamination, and the smaller it is, the cleaner the water.

The necessity of using air purifiers:

• Every year, millions of people around the world suffer from premature death due to complications of air pollution. According to a study published in The Lancet Science Magazine, nearly 9 million people died in 2015 because of breathing air pollutants, mostly in large and polluted cities. These deaths were caused by respiring suspended particles and carbon dioxide gas in the urban air and developing various diseases such as asthma, bronchitis, respiratory allergy, dyspnea, hypertension, palpitations, and heart or brain attacks. These pollutants first enter the lungs and then to the body's circulatory system in just 20 minutes, and by blocking the coronary arteries, increase blood pressure and eventually may terminate in heart attacks.
  
  
• The latest research manifest that air pollution increases blood pressure by hardening of artery walls, and causes heartbeat as well as heart attacks and brain strokes especially in the elderly and people with high blood pressure. Also, unfortunately, the impact of air pollution in inpatient older people is much more serious and, even after an hour of breathing the polluted air of major cities, these negative effects can be seen in their heartbeat, blood pressure, and respiration.
  
  
• In general, the air purifier removes toxic and harmful gases such as O3, SO2, NO2, CO, and CO2, by absorbing suspended particulates in the air and removing pollutant ions in industrial cities. Additionally, this device prevents the growth of fungi and mildew and greatly reduces the incidence of asthma and allergies.
  
  
• In addition to absorbing and disposing of suspended particles and air pollutants such as bacteria, fungi, viruses, and pollen, the domestic air purifier eliminates unpleasant smells in closed environments, and by completely purifying the air, it offers clean, healthy, and enjoyable air to consumers.
  
  
• Today, with regard to various types of pollutants in large cities, using air purifiers in all homes and offices has turned out to be one of the most essential requirements of urban living. In addition, we strongly recommend using double-glazed windows and UPVCs along with the air purifiers since they prevent the entry of soot and suspended particles.
  
  
• In the DamaTajhiz reference site, which according to Alexa.com global site data, is the first (since 2004) and the most visited air conditioners and air purifiers electronic shop in the Middle East, you can access comprehensive information about the chose product at the most affordable price (guaranteeing the best prices). We also ensure you about the after-sales service and original warranty.
  
  
• Due to the tangible effects of air pollution on the increase of respiratory, cardiac, allergic, and other diseases in large cities, using efficient air purifiers in thein order to produce clean, healthy fresh air will be very effective for treating asthma and allergies as well as respiratory, cardiac, and chronic sinusitis diseases. It is not surprising that in the absence of air purifiers (including the domestic types) in large and polluted cities, each child breathes suspended particles and poisonous respiratory detoxification as much as four cigarettes in a day, even if he does not leave the home.
  
  
• Pollutants leaked from cars, production units, or other sources are the most important agents of air pollution. Most of these pollutants that are not visible to the naked eye, cause serious harm to human health. Since the human eye is unable to see particles below 10 microns, most of the infections, such as bacteria and viruses can not be seen by the eye. Filters embedded in air purifiers such as HEPA filter, active carbon filter, and UV lamp can help remove and absorb particulate matters including dust, smoke, and chemicals. In some air purifiers, another technology called Electrical Attraction (electric gravity) has been used to break molecules. Electrostatic precipitators, electronic filters, and negative ion generators in air purifiers use this method.

The most important air pollutants:

• One of the most important factors that increase the number of soot particles in the city air is the continuous friction of cars and motorcycles with pavements, and the separation of soot particles from tires and their dispersion into the air. 
  
  
• On the other hand, incomplete combustion of fuels, using low-quality fuels, and high amounts of carbon dioxide emissions from vehicle exhausts (due to the lack of adequate airflow) add to the air pollution in the big city.

• Air pollution is 30 times more dangerous than smoke! As you know, smoking can cause lung cancer. Have you ever thought about why sometimes even non-smokers get lung cancer? Regarding the newest scientific research in the United States, free radicals in the contaminated air are pollutants that their effects on the human body are similar to consuming tobacco and cigarette.
  
  
• Exposure to this pollutant may cause a person to breathe free radicals 30 times more than a cigarette. HO Free radicals react with pollutant gases, such as VOCs which in many studies have been mentioned as a carcinogenic agent because if they are inhaled by the respiratory system, they can increase the risk of developing cancer cells.
  
  
• As you know, breathing in infected air is dangerous for children since they often breathe with mouth and therefore, more pollutants enter their bodies. In addition, because children's immune system is weaker than adults, the pollutants both negatively affect their brains development and increase the chance of getting infectious diseases. The main air pollutants include suspended particles, nitrogen dioxide (which increases lung infections), and sulfur dioxide and ozone (which cause asthma and respiratory system diseases). There is also the presence of lead particles, carbon monoxide, soot and de-suspended particles of 10 microns from other major sources of air pollution.
  
  
• Asbestos (mountain or fireproof cotton) is also another air pollutant used in brake pads and clutches to increase resistance against friction. Since this substance is proved to be a dangerous carcinogenic agent, its use in the automotive industry has been banned. However, the current amount of asbestos in the metropolitan airspace is significant and is considered the main source of air pollution.

What should we do about air pollution?

When air pollution is increased to a certain degree, schools will be closed at all education levels. In this situation, it is strongly recommended to prevent children and old people from leaving the home to reduce the risk of death.

- It is suggested that you observe the following when schools are closed due to air pollution:

• Do not take your child to shops, restaurants, or other public places.
  
  
• Do not leave your child outdoors with other family members for your convenience.
  
  
• Do not go out to see friends or acquaintances (even by getting a taxi).
  
  
• Use filter masks if you are forced to go out.
  
  
• Use public transportation.
  
  
• Do not forget to have fruits, vegetables, and especially liquids including green tea and milk.
  
  
• If you are forced to work in open spaces, wash your hands, mouth, and even your eyes thoroughly before eating.
  
  
• In summary, do not leave your home as much as possible since the risk of developing a heart attack, leukemia, and cancers due to air pollution is more than what you imagine.
  
  

What masks should we use during air pollution?

Currently, the suspended particles with dimensions of 2.5 microns are a factor contributing to air pollution in Capital cities. One way to prevent these particles from entering the respiratory system is to use special masks. Masks with the American NIOSH and European EN149 standards are among those capable of filtering these particles.

• When wearing the mask, prohibit air leakage from the surrounding area as much as possible.
  
  
• Use well-known brands of urban air pollution masks with the following standards: Totobobo, Respro, Vogmask and M3.
  
  
  
  
   

Types of air purifiers:

• There are various types of air purifiers, with different capacities and dimensions, to be used at homes, medical centers, and industrial environments. You can consult with experts in DamaTajhiz as the most important consulting and selling center of various air purifiers.
  
  
• In domestic air purifiers, various porous filters (with seeds or an integrated volume or fiber) are usually used to trap the air particles. Ultra-violet or UV lamps are also used to disinfect the air.
  
  
• Air purifiers working with filtering technology have different types. Below is a brief summary of each model.

1. Desktop Air Purifiers

Desktop air purifiers are presented in various brands with elegant designs, and small to medium size. These devices can easily be used at any point at home or workplace with good air circulation.

2. Standing Air Purifiers

These devices are usually larger than other types and can be used at homes, offices, companies, and even medical and therapeutic centers.

3. Portable Air Purifiers

You can easily hang a portable air purifier around your neck. This device, which uses ion absorption technology, provides clean, oxygen-neutral, and negative ion air for breathing in your surrounded environment (around the nose and mouth). This kind of air purifier helps people concerned about air pollution to leave and do their daily routines confidently.

4. Car-Air Purifiers

Since most streets are polluted, many people are reluctant to breathe air pollution in urban areas while in their car. Using a car air purifier is recommended to this group. This device is placed on the dashboard or the center console and is turned on by connecting to the car's cigarette lighter or with a stylus battery. By using the air purifier, you can safely drive anywhere in the city and do your daily routines. The car air purifier should not be exposed to direct sunlight or heat.

• As noted above, given the importance of breathing clean and healthy air as well as the presence of various contaminations including suspended particles, carbon black, and carbon dioxide gas and carbon monoxide gas in metropolises air, using air purifiers in homes and workplaces is not a choice but an inevitable necessity.

Internal filters in domestic air purifiers:

- Pre-filter: The pre-filter in domestic air purifiers is washable and can absorb tiny and larger particles such as lint, animal hairs, and suspended and allergen particles.

- Plasma Filter (ESP): This filter has an electrical charge (static electricity) and can absorb airborne particulates.

- Activated carbon filter: this filter is used in a variety of air purification devices including domestic ones. Because of having a high contact surface with harmful gases such as aldehyde, H2S, and NH3, odors and chemical contaminants like cigarette smoke and smell, smells of chemicals and sprays, this filter can absorb them. Carbon is combined with oxygen and active carbon is releases. The presence of this material at the filter surface results in high levels of absorption. Active carbon filters are the best option for removing chemicals, gases, and unpleasant odors released into the air due to their environmental compatibility.

- HEPA filter: This filter that its name is derived from High-Efficiency Particular Arresting, absorbs more than 97.99% of the airborne particles and produces clean and fresh air. Bypassing the airflow through the HEPA filter, the suspended particles are trapped inside the filter. HEPA filter performance depends on its thickness and fibers. Due to absorbing viruses, bacteria, germs, and particles smaller than 0.1 microns, as well as effectively filtering more than 0.97 of the air pollutants, HEPA filter is the most known filter to be used at homes, hospitals as well as surgery and sterilized rooms.

- Ultraviolet (UV) lamp: The UV lamp has a high disinfection effect due to its ultraviolet radiation and it destroys air microorganisms including bacteria, viruses, and fungi. The UV lamp absorbs viruses up to 97.6% and can fordo bacteria effectively with a wavelength of 254 mm.

- HEGA filter: Titanium dioxide or optical catalyst filter (Tio2): This filter is made of the semiconductor titanium dioxide. The optical catalytic filter with the UV lamp is among the most advanced filters and is the best absorbent of gaseous pollutants and chemical vapors, such as benzene and gas contaminants (permeated from cars). This filter also prevents virus activation.

- Nano Plasma Filter: This filter, equipped with nanotechnology, has the capability to absorb allergic and soot particles. Nanoparticles are powerful ions consisted of water molecules with a long-term life that penetrate the fabric of curtains, furniture, and room corners to absorb allergenic particles and eliminate contaminants. Nanoparticles are produced by the liquidated moisture in the air and hence, no water source is needed for producing them in the air purifier. As a result, these particles are dispersed in the environment with the airflow after being produced by the generator. Although the Nano filter has notable advantages, it has significantly increased the price of air purifiers.

- Negative ion generator: Most pollutants and allergenic materials are positively charged in the air while negative ions have a negative charge. Hence, there is magnetic traction among air suspended particles which causes the contaminants to stick together and to land due to their heavyweights before harming our health. It should be noted that if negative ions are not produced regularly, these massive pollutants will return to the air. Another advantage of negative ions is to make the respiratory system fresh. The existence of a negative ion filter in a domestic air purifier makes the airsoft and tender.

Selecting a domestic air purifier with a suitable capacity

When selecting a domestic air purifier for your home or office, in addition to attending the number of air filtration steps and the types of filters embedded in the device, the surface and dimensions of the main HEPA and active carbon filters absorbing particulate suspended particles, soot, and other contaminants should also be considered since the larger the dimensions and surface of the air purifier, the more air the device can purify. These devices not only clean the air more efficiently, but the fans operate with fewer rotations, speeds, and noise due to suitable filter dimensions. So, if you desire your device to work with less noise and speed, use larger air purifies with bigger filters.

Installing Air Purifiers:

• After purchasing and delivering the air purifier, you can easily remove it from the box, put it in the right place, and connect its plug to the wall outlet.
  
  
• Note: In some models of air purifiers, the filter must be removed from the protective plastic before installation. So, open the door before turning on the device to ensure that there is no plastic cover around the filter.
  
  
• The air purifiers should usually be installed away from the bathroom, kitchen, and exhaust fans.

Time of replacing filters of domestic air purifiers:

• An important point to ensure the correct operation of the air purifier is to replace the filters timely. Due to the air cooling from late autumn, air inversion phenomenon, and the fall of trees leaves in December, natural air purification by the leaves ceases until the end of the winter. Therefore, the best time to replace the filters of a domestic air purifier in some cities is in early December (Nano filter does not need to be replaced annually).

• If you use a domestic air purifier, it is best to close all doors and windows and to use UPVC seamless windows to prevent entering the contaminated air. Also, because of the presence of fatty particles in the kitchen, do not place any type of domestic air purifiers around the kitchen because these particles block their vents.

• Easy-to-carry and low-weight domestic air purifiers require a little space and consume low power. They turn the polluted air into a healthy and fresh one without producing a disturbing sound. In addition, most of the air purifiers are equipped with a timer and automatic rotation adjustment and let the consumer define different hours to turn them on and off during the day.

It should be noted that various types of air purifiers have no effect on cooling or warming the environment. Although the process of air purification is not observable, you can easily sense the air freshness in less than two weeks through checking the absorption and removal of suspended particles and other pollutants by Particle Counter test machine, improved health of the present people, as well as the accumulated contamination on the device filters.

Various technologies used in air purifiers:

Thermodynamic Sterilization System (TSS) technology

This technology, which is the latest technology provided in air purifiers, uses thermal sterilization by a ceramic core and the capillary property of the micro tunnels embedded in it (which is heated to 200 ° C). In this method, 99.9% of allergenic particles including bacteria, viruses, mites, fungi, molds, hair and dandruff are burned. When the ceramic core is heated, the contaminated air passes through the natural properties of airborne transfer from the inside of the ceramic core, and after the heat is taken, the clean and sterilization is released to the environment. TSS is not a filtration method, because instead of absorbing particles, it eliminates allergens and compared to other technologies, not only does not produce any harmful by-products, such as ozone and ion but also reduces centralization of harmful ozone in the environment. Among the advantages of this method, the silence of the filtration process and the no need for filter replacement can be mentioned.
