How to choose an air purifier

The air problem is getting worse and everyone is very concerned about air quality. In order to allow you to enjoy better air indoors, air purifiers are increasingly sought after by everyone. At the time of purchase, how should we choose an Air Purifier?

How to choose an air purifier

Select purifier to see the brand, R & D team

At present, the domestic air purifier market is full of various air purifier brands, and the technical route is dazzling. For example, Xiaomi uses HEPA filter, Panasonic uses nano-water particle technology, Sharp uses static Ion group space purification technology, and Daikin uses streamer energy purification technology. In this regard, relevant industry insiders said that no matter what kind of technology, price, brand of air purifier, most of the machines are similar in structure, and the working principle is the same. In addition to focusing on the brand, these products must also look at their core R&D team. .

Nowadays, the low-cost air purifiers on the market are below 1,000 yuan, the mid-end machines are around 2,000 to 5,000 yuan, and the high-end products are above 10,000 yuan. The high-end market is mainly occupied by foreign brands.

It is understood that the air purifier is mainly composed of a motor, a fan, an air filter and other systems. The working principle is as follows: the motor and the fan in the machine circulate the indoor air, and the polluted air passes through the air filter inside the machine, and various kinds of For the removal or adsorption of pollutants, some models of air purifiers also install an negative ion generator at the air outlet to continuously ionize the air, generate a large amount of negative ions, and send them out with the micro fan to form a negative ion airflow to clean and purify the air. purpose. Some high-purity air purifiers have many functions, such as sterilization, humidification, and odor removal of formaldehyde, and the materials are relatively high-end.

Choose a purifier, should choose a new national standard product

The filter element directly related to CCM (cumulative purification amount) has 20 grades from low to high, calculated by the cumulative purification amount of solid particles. The product CCM value of about 1000 yuan is generally 3000mg, and the CCM value of about 10,000 yuan is 60000mg. The difference between the two is 20 times, and the price difference is 10 times. However, this situation will be improved after the implementation of the new national standard for air purifiers. Users can refer to the “three highs and one low” principle when purchasing air purifiers: high CADR value, high CCM value, high energy efficiency ratio, low noise. The air purifier produced in accordance with the new national standard will indicate the detailed information of the product in the manual, and the user can purchase it as needed.

Compared with domestic brands' current air pollution situation, some imported air purifier R&D products are not suitable for China's high pollution national conditions. China is fully capable of developing air purifiers with independent intellectual property rights in line with national conditions. With the implementation of the new national standard, the air purifier products are constantly updated to enter the market. The enterprises with R&D teams are constantly updating and solving technical problems. Together with the price of the people and the close after-sales service, the domestic brands may change the imported air purification within two or three years. The device accounts for 70% of the pattern.

Pay attention to the filter standard of the filter

The filter standard for filters is marked as HEPA in English. Filtration absorbs chemical fumes, bacteria, dust particles and pollen. After filtering through an air purifier, these pollutants are not present in the air. However, only suspended particles can be filtered out and harmful gases cannot be filtered out. The air output of such air purifiers is generally not too large and is suitable for rooms with small areas. Pay attention to the timely replacement of the filter when using, otherwise the purification effect will be discounted.

Don't ignore after sales

In addition to considering whether the manufacturer is a manufacturer specializing in the production of air purifiers, pay attention to whether the OEMs are different in the real environment, whether it is Safe or not, and whether there is no secondary pollution. In addition, factors such as cost performance, word of mouth, brand strength and after-sales service need to be considered.

In the traditional electrical industry, after-sales is a "pit" for many users. When you buy it, you can't do it. If you have a problem and need to repair it, you will not be able to do anything. The users who should enjoy the products and services will pay more.
