What makes a good air purifier air purifier?

Air purifiers (also known as "air cleaners" or air purifiers) refer to the ability to absorb, decompose, or convert various air pollutants (generally including dust, pollen, odors, formaldehyde, and other types of decoration pollution, bacteria, and allergens). Etc.) Products that effectively improve air cleanliness are currently dominated by domestic and commercial air purifiers that remove indoor air pollution. Xiao Bian introduces us to the air purifier today.

Purchase and maintenance

When purchasing an air purifier, consider:

The performance of the air purifier is mainly determined by the clean air output ratio. The larger the clean air output ratio is, the higher the purifier efficiency is.

To make the indoor air quality reach a certain clean standard, the air purifier has two necessary hard indexes: 1. It must ensure that the indoor air reaches a certain number of air changes (international 5 times); 2. The air purifier is once cleaned The efficiency must be high. If indoor sources of pollution continue to occur, these two hard indicators of air purifiers can keep indoor pollutants at a lower concentration.

First, we must ensure that the indoor air reaches a certain number of air changes, that is, the built-in fan of the air purifier is required to have a certain amount of air flow. The international standard is to ensure that there are 5 air changes per hour in the applicable area:

Second, the efficiency of a clean air purifier must be relatively high, the higher the purification efficiency (CADR), indicating that the better the air purifier

There are three indicators for the purification efficiency (CADR) value:

1, solid particles, also known as dust (Particle), the domestic usually use cigarettes to simulate, so also known as smoke

2. Volatile Organic Compounds (VOC), Usually Tested with Toluene

3, formaldehyde (Formaldehyde)

Because the general air purifier is very obvious for dust removal, and the effect of volatile organic compounds and formaldehyde is not as good as dust, so many businesses only indicate the CADR of dust.

Precautions

First, whether it has absolute security.

To buy an air purifier, you just want to use it for a healthy, fresh air. Whether or not an air purifier is safe is the basic prerequisite for determining whether it is desirable. Air purifier shell, movement and purification technology will directly affect the safety of the air purifier. The purification technology should be the same as the positive and negative ions in the natural world, and there are 13 international organizations that certify the safety of ion purification technology.

Second, whether it has a scientific purification principle and achieve an efficient air purifier effect.

There are five principles of international air purification, physical, electrostatic, chemical, anion, and compound. In general, physical purification is the most common and effective method. For example, dust, pollen, allergens, viruses, and other large particles can be filtered by HEPA technology in physical purification; harmful substances such as benzene, toluene, formaldehyde, and other odors can be absorbed by activated carbon in physical purification methods. Purification.

According to the way of purification, it divides from the active direction, the purification method is divided from the active direction, and there are three kinds of active purification methods (air purification), passive purification methods (fixed-point purification) and active-passive compound purification. The passive purification method only has a purifying effect on the inhaled air; the active purification method will have a purifying effect on the entire space. Active and passive compound purification is a combination of both, and the effect is even better.

Active purification is a controversial technology in the international community. Because the pollutants in the air are generally one-hundredth or less in concentration, and the active purification requires spraying a higher concentration of chemical substances into the air, the pollution level of the air is even increased as a whole. For example, the release of ozone into the air is strictly prohibited in European and American countries.

Third, whether it meets specific purification needs.

As far as the air purifier is concerned, the purifying function is the most concerned function. If your requirements for indoor air purifiers are based solely on improving indoor air quality, you can choose purely clean air, a cost-effective type.

With the increasing demand for quality of life, the demand for air purifiers is no longer simply purifying indoor air. For example, those who work in a closed air-conditioned room, because of the dehumidifying effect of air conditioning, the air in the room becomes very dry, and the skin becomes dry. Therefore, when selecting an air purifier, it will purchase a skin function. Humidifier air purifier.

For people who are in long-term crowds and have large indoor pollution, they need to breathe fresh air without bacteria. When choosing an air purifier, they will prefer a small k air purifier that is suitable for use on the desktop.

And people who own their own cars should choose car air purifiers to clean up all kinds of car odors and even ease their fatigue.

Fourth, purchase in conjunction with market sales and third-party authoritative certification.

A high quality home air purifier must have the ability to sterilize and remove odors. When purchasing an air purifier, special attention must be paid to whether its bactericidal power and odor control ability are indisputable. In general, sales volume is a key market inspection indicator.
