Don't easily buy an air purifier without doing your homework, for fear that you'll buy an expensive one without buying the right one.

According to the World Health Organization, we have to breathe about 20,000 times a day, so the quality of the air we breathe is directly related to our health.

In the pursuit of quality life, air quality is a link that cannot be ignored. Have you ever felt breathless in hazy days? Or are you worried about the dust in your home, pet hair, and even formaldehyde and other harmful substances affecting the health of your family?

Today, let's talk about air purifiers - the guardians of health in this modern home - and how to buy an air purifier that's right for you.

01. Who needs an air purifier?

1. Allergic people For people who are allergic to pollen, dust mites, pet dander, etc., air purifiers can effectively filter these allergens and reduce the occurrence of allergic reactions.

2. Infants, young children and the elderly, whose domiciliary systems are more sensitive and fragile, are easily affected by air pollutants. Air purifier can provide a fresher and healthier home living environment to protect their healthy growth and later life.

3. Smoking families, the harm of second-hand smoke can not be ignored, especially smokers at home, often smoky family, an air purifier can help remove indoor smoke and harmful particles.

4. Newly renovated home renovation indoor residual formaldehyde, benzene and other harmful gases, if you want to live in as soon as possible, then arrange an air purifier, can accelerate the purification process, to protect the safety of living.

5. the pursuit of high quality of life in the busy pace of life, a fresh home environment can undoubtedly enhance the quality of life, so that people are more pleasant mood.

02. Is it necessary to get an air purifier?

The answer is that it is recommended. With the acceleration of industrialization and the increase of urbanization level, the air pollution problem is more and more worthy of our attention. Air purifiers can not only effectively remove pollutants in the air, such as pollen, dander, pet hair, PM2.5, etc., plus remove most bacteria, viruses, but also improve the quality of indoor air, creating a fresher, healthier living environment for us. Especially in the haze frequent, poor indoor air circulation season, a good performance air purifier is indispensable.

03How to choose and buy?

A. Determine the needs

The more features a purifier has, the higher the price naturally is, and the higher the cost of replacing the filter cartridge later. To understand their own needs, according to the needs of the purchase, you can spend less money.

If the local air is bad, or keep cats and dogs, and want to improve the indoor air quality, choose a purifier whose main selling point is to reduce PM2.5 content. If you have just renovated a new house and want to remove harmful indoor gases, choose a purifier whose main selling point is to reduce formaldehyde and TVOC. If you want to prevent flu and remove airborne bacteria, choose a purifier with this selling point. If you don't care about money, buy a full-featured high-end model.

B. 2 parameters to focus on when buying different brands of purifiers, have their marketing filter technology and aldehyde removal technology, we do not have to study the comparison, just look at the most important 2 parameters.

1. Look at the CADR value

CADR, that is, the clean air output ratio, is a key indicator of the purification efficiency of air purifiers, indicating how many cubic meters of air can be purified per hour. The higher the CADR value, the faster the air purification speed, the better the purification effect, which can be applied to a larger area of the space. CADR value must be separated in the parameters of the solid and gaseous values. When choosing an air purifier, you should choose a model with a suitable CADR value according to the size of your room. Don't believe in “99% aldehyde removal” metaphysics CADR (clean air output rate) is the lifeblood of the purification speed. 2! Simply put: formaldehyde CADR value ÷ 10 ≈ applicable area (square meters). New room formaldehyde concentration is high, choose formaldehyde CADR> 400m³/h model, otherwise it is “psychological comfort machine”.

2. Look at the CCM value

CCM is the cumulative purification capacity, which indicates how much mass of pollutants can be processed cumulatively when the processing capacity has decayed to half. The larger the CCM value is, the stronger the processing capacity of the cartridge, the longer the service life, and the higher the cost of the cartridge, but the cost of the after-use is low.

To make it easier to remember, the CCM value is divided into 4 grades, solid CCM from P1 to P4, gas from F1-F4, grade 4 is the highest.

The replacement cycle of the cartridge has a lot to do with the daily use time and indoor air quality. It cannot be determined simply by the CCM value. It can only give an average replacement cycle, such as 20 square meters of room, P3 filter can work for 3 months, F3 filter can work for 1 month. Solid filters are mainly activated carbon filters, which have the longest service life. Gaseous filters are mainly HEPA filters, and independent HEPA filters usually have a replacement reminder function.

CADR value and CCM value are the most important two parameters of the purifier, which have an important impact on the price of the purifier. 3.

Recognize the “decomposition technology”, reject the secondary pollution activated carbon adsorption formaldehyde?

Once the filter is saturated, it will “spit poison” back into the house! The real king is chemical decomposition technology (such as nano-catalytic, photocatalyst), formaldehyde can be split into water and carbon dioxide. The real king is chemical decomposition technology (such as nano-catalytic photocatalyst), which can break down formaldehyde into water and carbon dioxide.

3. Concerned about the noise level

air purifier operation will produce a certain amount of noise, long-term living in a high-noise environment, will have an impact on human hearing and mental health. Therefore, when shopping for low-noise design products, especially bedroom use of the purifier, should pay more attention to the effect of silence, to the quiet gear / sleep gear for the lowest power level reference, the best decibel can be less than 35db (decibel).

4. Filter quality and technology

Filter is the core component of the air purifier, and its quality and technology directly determine the purification effect. Common types of filters include HEPA filters (High Efficiency Particulate Air Filter), activated carbon filters, etc. HERA filters are effective in filtering tiny particles, while activated carbon filters are good at adsorbing harmful gases and odors. In addition, some high-end products also use photocatalysts, negative ions and other advanced technologies to further improve the purification effect. When choosing, it is recommended to choose multi-layer composite filter design to ensure all-round purification.

By understanding our own needs and focusing on CADR, CCM value, noise level and cartridge quality and technology, we hope that we can pick the right one for our family among the many products available to make every breath a burden-free experience.
