The following answers are given to the above questions
Not everyone needs an air purifier if you are:

If someone smokes or has pets at home, it needs to be deodorized and sterilized;

Family members have rhinitis and are prone to allergies to dust or pollen;

The air quality in a big city is poor, and there are elderly and children at home who have higher air requirements;

Then an air purifier is necessary and useful for you.

However, the price of air purifier products on the market now ranges from more than 1,000 yuan to more than 5,000 yuan, and the price range is very large. How to choose is also a problem. Now, let's talk about it in detail, take three minutes to go and see it with Kaisen.

Classification of air purifiers
Different types of air purifiers have their own characteristics. Generally speaking, their structure is composed of three parts: motor, fan, and filter system. The difference lies in the way of filtering.

One air purifier is passive adsorption filtration.

This is to wait for the fan to send in the polluted air before it starts to function. After the polluted air involved in the purifier passes through the built-in particulate filter or orga nic filter, the pollutant molecules are adsorbed and filtered by the filter, so as to achieve the effect of purifying the air. When choosing this type of air purifier, the type of fan and the quality of the filter are important.

The second category air purifier is active purification.

This kind of purification can be activated automatically without waiting for the fan to send dirty air. The principle is to add a strong electric field to the purifier, and actively "attract" pollutant molecules through technologies such as negative ions, silver ions, plasma, and ion group ions, and some will release sterilization factors into the air, but there will also be ozone. We should pay attention to the problem of excessive release.

air purifier

The third type is the combination of the above two. The purpose of basic disinfecting and purification is achieved through passive filtration, and then the active method is used to purify dust, odor and bacteria in an all-round way.

I don't say the above three, I believe everyone can understand, the more technology is added, the higher the price will be. Of course, there is no strict level of pros and cons.

Specific to individual products, when we choose, we must be optimistic about these two types of parameters: core parameters and non-core parameters.

Air purifier core parameters
CADR value

CADR refers to how many m3 of clean air can be output per minute. Whether it is passive filtration or active purification mentioned above, in fact, the core capability is still in the filter element, and whether the filter is activated carbon, filter paper or other materials, CADR can be used to evaluate its purification efficiency.

Generally, manufacturers will use particulate matter and formaldehyde to test the value of CADR. For example, if you just want to remove more formaldehyde after decoration, you can focus on the formaldehyde/gaseous CADR. Of course, not everyone will mark it. Usually, it will also indicate "" able to cope".

However, it should be noted that the CADR value is related to the applicable area of the air purifier. The higher the CADR, the more dynamic air circulation in the space. Therefore, if we seem to need to use an air purifier in the living room, we can choose a larger CADR value.

CCM

This value refers to the total mass of gaseous and particulate pollutants that the air purifier can purify from the start of use to the final failure. The higher the value, the more durable the filter element will be.

Considering that the filter element and filter are consumables, if you don't want to cause trouble with frequent replacement, it is definitely more convenient to choose a higher CCM level.

Since the filter element is mentioned here, I think it is necessary to add the filter grade, because the filter used for passive filtration or active purification is also different.

In passive filtration, activated carbon is the most basic method, and the effect of using it to adsorb gases such as formaldehyde is very good.

HEPA mesh filtration technology mainly filters dust particles, which can be subdivided into 17 grades: G1-G4, F5-F9, H10-H14, U15-U17. Most of the filters used at home are H-level filters.

Other filter technologies such as photocatalyst and cold catalyst can decompose harmful gases, and the effect is better than that of activated carbon, but the price is also more expensive.

Air purifier non-core parameters
Noise

This is easy to understand, no matter what kind of electrical appliance we buy, we all hope that the noise it makes when it is working will not be too loud. Usually a good air purifier will control the noise at about 35 decibels through better configuration, which is the sound that will not affect sleep.

It is recommended that you go to the offline field to experience it, and you will know more in your heart.

Finally, if it is a large-area room, considering the entire air circulation, we must also pay attention to the problem of the air supply from the bottom. Automatic opening.

In short, it is worthwhile to prepare an air purifier for a family in need. You can refer to the points mentioned above and choose the one that suits you according to your budget.

Well, that's all for today. If you want to get more industry-related information, you can pay attention to Kaisen. See you in the next issue.
