Replacing the filter of the air purifier

The air purifier needs a lot of attention and care to function properly and usefully. One of the care methods is to change the filters of the device regularly and according to the needs of the device. When you buy an air purifier, you will probably ask yourself how long the life of its filter is or when will it be time to change the filter of the air purifier.
Since almost all air purifiers need filters to absorb pollution from the air, the lifespan of these filters will be very important. Filter replacement time depends on their type and model. By learning about the model you are looking for, you can be sure of the proper and accurate performance of the air purifier you have purchased.



Not changing the filters on time and regularly causes the efficiency of your air purifier to decrease significantly, in fact, the device is no longer able to purify a significant amount of ambient air in the shortest possible time, on the other hand, not changing the air purifier filters increases the costs. Your device will be maintained and repaired.

Time to replace the filter of the air purifier

Changing the filter of the air purifier must be done in a certain period, which of course depends on the type of filter and some other factors. Knowing and paying attention to the maintenance of important parts of the air purifier, such as the filter, will help you to see better performance from this system.
How long does it take to change the filter of the air purifier?
The time interval for replacing the filter of the air purifier depends on various factors:

Ambient air quality

The more polluted the air that is normally in the space, the less time it takes to change the filter of the air purifier and you need to change it more quickly. If your home or workplace is located along a busy road (full of cars that produce pollutants), or if many people smoke in the space and even pets live with you, the air purifier filter should be replaced in a shorter period.

Amount of system usage

An air purifier that is used 7 days a week, 24 hours a day, needs more maintenance than a device that is used only on certain days. So, if the device is turned on regularly, its filters should be replaced more quickly.

Filter type

The duration of changing the filter of the air purifier has a direct relationship with its type. For example, the lifetime of the HEPA filter is much longer compared to other filters, and in the best case (especially in the types of nano filters), it can have a useful life of between 3 and 5 years. However, some filters must be replaced monthly.
Knowing the best time to change air purifier filters can be confusing. That's why some devices alert people when it's time to change the filter with an LED indicator and a beep. Of course, it should be noted that not all models of air purifiers come with this feature.

Do all air purifier filters need to be replaced?

According to the type of product and the manufacturing company, some factories make air purifiers in such a way that their future costs are lower. They do this by considering reusable or washable filter devices that can be opened, washed, and put back in the original place during each service period, and they oblige the user to Wash these parts according to the instructions. But on the other hand, regardless of whether they are disposable, washable, or permanent, all filters have a useful life, and it is not possible to wash and clean a filter for many years, and it is necessary to replace these filters from time to time. Replace the complete shape. To schedule and use them, their replacement schedules are provided, which are:

• HEPA: Every 12 to 18 months
• Pre-Filters: Must be every 30 days
• Carbon filters: should be every 3 to 6 months
• Permanent filters: wash once every 3 months (change if there is a physical problem)

The best time to change the filter of the air purifier

The best time to replace the filter of the air purifier depends on various factors, some of which we have mentioned below:

• Indoor air quality

The more polluted the indoor air in your home is, the faster the filter becomes saturated, and as a result, it needs to be replaced faster. For example, if your house is located in the city centre or in a busy neighbourhood where there is a lot of car smoke and air pollution, you should change the air filter of the purifier as soon as possible.

• The amount of use of the air purifier

If the air purifier in your home is on 24 hours and every day of the week, it is very clear that the filter will fill up faster; compared to a device that is turned on every once in a while, it needs more frequent replacements.

• The quality of the water in the device

Another thing that has a direct effect on the useful life of the filter is water quality. Washable filters are more likely to lose their efficiency faster if they are washed with heavy water and water that has a lot of salts; Because the solutes in the heavy water are deposited inside the filter tissue and will cause its pores to close.

• Different filter models

Different filters have different useful lives. For example, normal filters should be changed once a month; But HEPA filters have a longer useful life.
