According to the operating principle, air purifiers can be roughly divided into active, passive and composite modes. The three modes have their own advantages and disadvantages. However, according to the overall product preference of major brands, composite air purifiers occupy most of the market.
The composite air purifier combines some active and passive technologies, drives the fan to operate through the motor, sucks indoor air into the product, filters it through professional sterilization, aldehyde removal and haze removal devices, and then releases clean air into the air, slowly completing the circulation and purification of the entire indoor environment. The composite air purifier needs daily cleaning and regular replacement of the filter screen. Mastering the correct replacement method of the filter screen can improve the overall use effect of the product and the service life of the filter screen. Today, I will explain the cleaning problem of the filter screen, hoping to help you clean the filter screen easily.
air cleaner
1： Primary filter screen
The primary filter screen is the primary filter screen for filtering large particles, hair and dander in the first layer. This layer of filter screen includes non-woven cotton material, glass fiber material and general plastic fiber filter material. The cleaning methods of primary filter screens made of different materials are different. For example, glass fiber and general plastic fiber materials usually only need to be washed and dried, and do not need to be replaced. They can be used for a long time. The initial effect filter screen of non-woven cotton cannot be washed by water and needs to be replaced regularly. During daily cleaning, only the dust on the filter screen needs to be cleaned.
2： HEPA filter
HEPA filter screen is one of the filters that almost every air purifier will be equipped with. There are various HEPA filter screen materials, including PP filter paper, glass fiber, composite PP pet filter paper, melt blown polyester non-woven fabric and melt blown glass fiber. Usually, the glass fiber HEPA filter screen can be washed with water, but the melt blown polyester non-woven fabric, PP filter paper and composite PP pet filter paper can not be washed with water. They can only absorb the dust of the filter screen through a vacuum cleaner, Or gently brush it off with a brush.
3： Activated carbon, nano mineral crystal, photocatalyst and other aldehyde removal materials
Most of the materials used for removing aldehydes in air purifiers are activated carbon, nano mineral crystals and photocatalysts. These three kinds of materials can not be washed with water, but can only be exposed to the sun. The exposure time should not be too long, just a few hours

How to distinguish different indoor pollutants?
It was found that many owners would come to consult about smell after indoor decoration. Some have been newly renovated for several months, and some have even been renovated for several years. They can smell "decoration" in the closed room. What is the taste of decoration? How to distinguish different indoor pollutants? 1. Formaldehyde is a colorless, tasteless and irritating gas Formaldehyde is colorless and tasteless in a strict sense, but when the concentration exceeds 3 or 4 times, it will stimulate and damage human mucosal tissues, such as sore throat and inability to open eyes. But this is not the main danger. The main hazard is that formaldehyde rapidly enters the blood through the alveoli through the respiratory tract, causing incalculable harm to the human body. Formaldehyde mainly comes from artificial wood used as decorative materials, such as adhesives in plywood, core board, medium density fiberboard and creative board (particleboard). So usually, the simple smell we smell is not caused by formaldehyde, even if formaldehyde exceeds the standard by 1-3 times. 2. Benzene is an aromatic gas The smell of benzene is fragrant, and some people feel like the taste of bitter almond. Therefore, many experts call it "fragrance killer", as long as the source of benzene is paint, especially oily paint. Benzene also has other uses, that is, artificial fragrances and essence may contain benzene. 3. TVOC is the general name of organic compounds in the air Usually, the smell you smell when you decorate is TVOC, because it contains eight kinds of organic compounds. However, there are also cases where VOC seriously exceeds the standard, but there is no task odor indoors. The main sources of volatile organic compounds are paints, adhesives, fabrics, textiles, etc., and some of them come from the incomplete combustion of coal or tobacco. Ammonia is a kind of malodorous gas In our daily life, the smell of ammonia is the smell of fertilizer. Colorless, but highly irritating and smelly. If you live in a city and don't know the smell of fertilizer, you should be exposed to the unpleasant smell of public toilets in summer. Ammonia is mainly used as an antifreeze in cement, usually appearing in the north, but rarely exceeding the standard in the south. Radon is a colorless and tasteless inert gas Radon gas is formed by radium radiation decay from marble and granite. It is colorless and tasteless. Because it is an inert gas, it will not react with any organic matter. Their presence cannot be distinguished by sight and smell, and they can usually be detected by special institutions.
