Detailed steps, how to clean and maintain the air purifier?

With the air quality going on, more and more families are starting to use household air purifiers. However, unlike ordinary household appliances, air cleaning requires regular cleaning and maintenance, otherwise, it will affect the machine and health:

For example, the damage filter and the life of the machine itself can be used for one year. If the maintenance is not paid attention to, it may be scrapped in half a year;

In addition, the purification efficiency will be greatly reduced, so it must be scientifically used, pay attention to maintenance ~

What is the use of science?

Use in a dry environment

In a humid environment, it is easy to breed bacteria; secondly, floating water mist will be detected as harmful particles, increasing the networking pressure.

Many people opened the humidifier at the same time as they had a good night’s sleep. As a result, the net was full of horsepower and screaming, but they couldn’t sleep.


In order to facilitate the room to walk, but the empty net in the corner; worry about the formaldehyde emitted by the furniture, empty and directly placed on the side?

In fact, this will only hinder the circulation of airflow into the wind and the wind, and reduce the rate of air renewal.

The best position is of course placed in the middle of the house. I really worry about getting in the way of my feet. At least I have to leave the wall more than 1m away.

How to properly maintain and maintain?

External maintenance of the chassis

Empty nets After a long period of use, the chassis must be attached with dust. Pay special attention to the dirt near the sensor, because they will affect its sensitivity, and let some harmful substances gradually become the “fish of the net!”

The sensor is often narrower and needs to be cleaned with a soft brush before it is wiped clean with a dry cotton swab. It is recommended to clean it every 2 months. (Do not clean the sensor with detergent or metal objects).

The rest of the chassis can be wiped with a damp cloth or a softer towel.

Air purifier filter maintenance

Next is the heavy head! Air purifiers generally have three layers of screens, each of which is made of a different material to absorb different air pollutants, so it needs to be cleaned in different ways:

▪ Primary filter ▪

In the outermost layer of the empty net, it mainly absorbs large pollution such as hair, pet hair, sand, and gravel; generally, it is cleaned 1-2 times a month, the filter screen is removed, and the dust can be removed by using a vacuum cleaner or a rag.

▪ HEPA filter ▪

This is the most important filter for empty nets, which removes more than 99% of 0.3-2.5 micron particles. Effectively block PM2.5, bacteria, allergens, and other harmful substances, so are careful when cleaning.

HEPA filters are not washable because they are usually made of polypropylene or other composite materials. Similar to paper, brushing with water can damage the filter structure.

You can use a vacuum cleaner to clean the dust, almost once a month. If you feel that it has become very dirty after using it for a long time, then it is best to change a new one, don’t feel bad about it.

▪ In addition to formaldehyde filters ▪

If it is activated carbon in addition to the formaldehyde filter, it is good to expose it directly under the sun. Activated carbon belongs to physical adsorption, and the formaldehyde adsorbed in it is released by the temperature rise.

Therefore, if it is not taken care of, the formaldehyde adsorbed in the winter will be released again in the summer, and secondary pollution will be formed.
