Air Purifier

Important Tips on Choosing Different Types of Air Purifier:

Before explaining the importance and necessity of increasing use of air purifying equipment at home and at work and the efficient and effective operation of air purifying devices, we announce that since 2004, Dama Tajhiz Co. delivers purchase orders of a variety of air purifiers in Tehran in 2 to 4 hours by free shipping and in other cities for up to two business days (based on distance) with the most suitable prices.

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.
  
  
• Based on the studies of the Comprehensive Traffic Plan of Tehran, more than 9,200 tons of pollutants are daily flown to Tehran air by various air pollutants, especially cars. According to the United Nations report in 2007, in general, Iran's major cities are ranked 117th in the Air Index Table among 133 countries. As mentioned before, air purifiers play an important role in reducing or eliminating air pollution in our homes and living environments. In Iran, the most air-polluted cities are usually Tehran, Ahvaz, Arak, Isfahan and Zahedan.
  
  
• Given the results of a study conducted by the World Health Organization, the death toll from Tehran's air pollution was about 4500 in 2013, often caused in fall and winter, due to breathing air suspended particles. These pollutants first enter to 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 patient older people is much more serious and, even an hour of breathing the polluted air of major cities, these negative effects can be seen in their heartbeat, blood pressure and respiration. (Watching the following video is strongly recommended).
  
  
• 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 the air purifiers since they prevent the entry of soot and suspended particles.
  
  
• In the Dama Tajhiz reference site, which according to t 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 with 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 amount 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 pollutants 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 as the main source of air pollution.

What should we do during 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 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 Tehran city. 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 capacity and dimensions, to be used at homes, medical centers and industrial environments. You can consult with experts in Dama Tajhiz 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 the 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 to 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 in 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. By passing 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 which 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 a magnetic traction among air suspended particles which causes the contaminants to stick together and to land due to their heavy weights before harming our health. It should be noted that if negative ions are not produced regular, 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 air soft 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 less rotations, speeds, and noise due to suitable filters 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 installing. 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 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 of ceases until the end of the winter. Therefore, the best time to replace the filters of a domestic air purifier in cities such as Tehran, Isfahan and Arak 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 microtunnels 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.
