Near the double 11, in order to help you buy cost-effective filters and air purifiers, to talk to you about these issues.

First, air purifiers in the end useful

Air purifier (air purifier), also known as "air cleaner", air freshener, refers to the ability to adsorb, decompose or transform a variety of air pollutants (generally including dust, pollen, odors, formaldehyde and other decorative pollution, bacteria, allergens, etc.), to effectively improve the cleanliness of the air products, and is currently used to eliminate indoor Currently, home and commercial air purifiers are mainly used to remove indoor air pollution.

At present, many home users to buy air purifiers are mostly filter-type products, these products in the process of use, not a use in the end, but also in its filter adsorption will be nearly saturated when the replacement of the filter to ensure that the product can normally play their role in improving indoor air quality.

Second, how often do air purifiers replace

So, how often do you have to replace the filter? Industry analysts said that the air purifier filter on the market is generally only three or four layers, and some good products have five or six layers. At present, there are five mainstream filters on the market, including pre-filter, washable deodorant filter, formaldehyde removal filter, HEPA filter and humidification filter.

In terms of cleaning and replacement, the air purifier pre-filter can adsorb small dust particles in addition to the effective removal of hair, take it out with a brush or something can be cleaned, of course, if you do not have the economic pressure, usually cleaned once every 3 months, when the haze is serious, cleaned once every 1 month.

Washable deodorizing filter, this filter can be cleaned with water, and performing regular cleaning can restore the deodorizing performance, which can effectively remove sweat odor, pet odor and other odors. It is recommended to clean it once every 3 months when the air quality is good and once every half a month when the air quality is poor.

Formaldehyde Removal Filter, this filter traps and locks formaldehyde firmly in the filter for decomposition. It is recommended to change it at least once in 2 months if you want to use it to clean up indoor decoration pollution.

This type of filter can be cleaned with water, usually twice a year on the cleaning. If the air quality is not good, it is recommended to clean it once in 2 months.

Third, double 11 how to buy air purifier

brand watching

At present, there are many air purifier products on the market, the brand is not the same, the product technology and selling price is not the same. Such as Sharp uses static ion cluster space purification technology; Panasonic uses nano water particle technology; Daikin uses flow light energy purification technology. However, the air purifier brand regardless of what technology it uses, how the price, the construction of the machine between the brands is similar, the principle of work is the same, so the user in the purchase of air purifiers, it is recommended to start with the technology accumulation of the brand.

Whether the new national standard products

With CCM (cumulative purification capacity) directly related to the cartridge, from low to high there are 20 levels, to the cumulative purification of solid particulate matter, generally about 1000 yuan of products CCM value in 3000mg, while about 10000 yuan of CCM value of 60,000mg, which is 20 times the difference between the two, the price difference of 10 times. However, after the implementation of the new national standard for air purifiers, this situation can be improved.

You can refer to the "three high and one low" principle of air purifiers to start, that is: high CADR value, high CCM value, high energy-efficiency ratio, low noise. In accordance with the new national standard production of air purifiers will be marked on the manual product details, when the user can buy as needed.

Compared with domestic brands familiar with China's current air pollution situation, some imported air purifiers R & D products are not suitable for China's high pollution situation. Domestic brands are developing new products according to the new national standard, and have launched a lot of air purifiers suitable for home use in the past few years. You can check the CADR value, CCM value, energy consumption and noise, as well as the applicable area of the product to buy.

Look at the filter

The filter standard English labeled HEPA. filtering absorption of chemical fumes, bacteria, dust particles and pollen, the air purifier filtered by the air, the air is free of these pollutants. However, it can only filter out suspended particles, not harmful gases. This type of air purifier's air output is generally not too large, suitable for small rooms. When using it, you should pay attention to timely replacement of the filter, otherwise the purification effect will be discounted.

Look at the aftermarket

Choose an air purifier in addition to consider whether the manufacturer is a professional manufacturer of air purifiers, pay attention to the difference between the labeled manufacturers, in the real environment whether the real effect, whether the safety of no secondary pollution. In addition to this, you also need to consider the reputation, brand strength and after-sales service and other factors.

In the traditional electrical industry, after-sales for many users is a "pit". Buy the time to say the sky is the limit, if the problem really need to repair a variety of ineffective, and the most should enjoy the products and services of the user is to pay more costs. Therefore, it is still recommended that we refer to the technology and after-sales service to do more mature enterprises as well.
