Air purifier working principle air purifier brand

As air pollution becomes more and more serious, in order to breathe better air, we use an air purifier to purify the air. Air purifiers are now very common. But for the working principle of air purifiers, many people are not very familiar with it. Now let's understand how the air purifier works.

How air purifiers work

1: Passive purification class (filter purification class)

The main principle of the passive air purifier is to use a fan to pump air into the machine and filter the air through the built-in filter, which can mainly filter dust, odor, toxic gas and kill some bacteria. The filter is divided into: dust collection filter, formaldehyde removal filter, deodorization filter, HEPA filter, etc. Among them, the higher cost is the HEPA filter, which has a very obvious effect of filtering particulate matter, and can decompose toxic gases and sterilizing effects, and can suppress secondary air pollution.

The quality of the fan and filter of this type of product determines the effect of air purification. The location of the machine and the layout of the room also affect the purification effect.

2: Active purification class (no filter type)

The fundamental difference between the principle of active air purifier and the principle of passive air purging is that the active air purifier is free from the limitations of the fan and the filter screen, and is not passively waiting for the indoor air to be pumped into the purifier for filtration and purification. It is an effective and active release of the purification and sterilization factor into the air. Through the characteristics that the air will diffuse, it will reach the corners of the room and clean the air without dead angle.

At present, the technologies for purifying sterilization factors on the market mainly include silver ion technology, negative ion technology, low temperature plasma technology, photocatalytic technology and plasma ion group ion technology.

3: Double purification class (active purification + passive purification)

This purifier is actually a combination of passive purification technology and active purification technology.

4. Comparison of active and passive purifier principles

Compare the efficiency of air purification. Passive adsorption purifier adopts fan + filter mode for air purification. The principle of using air flow alone will inevitably have dead angles. Therefore, passive air purifiers can only place a small space in the air purifier to produce certain Purification effect, only after a long time is passed before the indoor air can be completely filtered.

The active air purifier utilizes the diffuse nature of the air to spread the purification factor to all corners for air purification, so that the air can be purified in a place where it can be diffused. Comparing with the negative ion air purifier, it is found that after the negative ions are released from the air, the negative ions can actively attack, find the pollutants in the air, and agglomerate into a group to actively settle them. From this point of view, active air purification has obvious advantages.

Air purifier brand recommendation

Philips Air Purifier Royal Philips Electronics of the Netherlands is a diversified company that is “healthy, comfortable and quality of life” and is committed to improving people's quality of life by introducing meaningful innovations in a timely manner. Philips air purifiers not only use H12 high-efficiency HEPA filter (higher than the H10 grade commonly available on the market), but also use the unique HESA (Highly Efficient Selective Adsorption) filter layer to selectively remove chemically harmful substances. After adsorption, it degrades into harmless particles. According to the inspection results of Shanghai Environmental Protection Product Quality Supervision and Inspection Station, the product can not only quickly eliminate up to 99.9% fine particles such as dust and pollen as small as 0.3 microns, making the PM2.5 in the car nowhere to be shaped; Up to 99% toluene, benzene, xylene and volatile organic compounds. For smaller bacteria such as H1N1 and viruses, the German Association of Energy and Environmental Technology shows that the effective removal rate is over 70%.

Panasonic air purifier Panasonic air purifier features first feature is nanoe nano water ion technology, nanoe nano water ion production first requires nanoe nano water ion generator to coagulate water, and then by applying high voltage to separate water molecules Generated charged water particles. The nanoe nano water ions can diffuse into the room with the purified air. Bringing users a fresh and comfortable indoor air environment. The humidifier of the air purifier is also uniquely vaporized to achieve a more delicate humidification effect. After the moisture passes through the humidifying filter, the purified air is uniformly diffused into the room to improve the drying space. Keep indoor air moist and fresh at all times. The waterwheel-type humidifying filter allows for both humidification and washing, and is also equipped with a self-standing water tank for water cleaning.

Yadu Air Purifier Yadu Air Purifier Molecular Complex Locking Technology--This technology is aimed at indoor decoration pollution of formaldehyde, benzene, ammonia and other pollutants, the molecular complex lock, and then through the Yadu proprietary formaldehyde trapping agent and water The complex decomposition system converts gaseous short molecular chain substances such as formaldehyde and ammonia into complex irreversible long-chain molecular solid substances and decomposes them to form ammonia salts. Yadu air purifier adopts UFCO technology (super normal temperature formaldehyde catalytic oxidation technology)--this technology uses metal nitrates or carbonates and other soluble inorganic salts to obtain metal oxides by oxidation precipitation. A small amount of precious metal is supported on the metal oxide to obtain a high formaldehyde oxidation activity at room temperature, and the formaldehyde can be decomposed into carbon dioxide and water at room temperature.

The working principle of the air purifier is actually not as complicated as we think. There are many brands of air purifiers, only a small part mentioned above. Regarding the working principle of the air purifier and the contents recommended by the air purifier brand, we will introduce so much to you today, and we hope that our introduction will be useful to everyone.
