The air filter in the fresh air system, is the more layers the higher purification rate?

in the new air conditioning systemAir FilterIs it true that the more layers you have, the higher the purification rate?

Is it true that the more layers of fresh air filters, the better the purification effect? Different businesses say different things, which makes it difficult for many people to choose the right new air system. So, the more layers of filters in the new air system, the higher the purification rate of the new air?

The answer is no.

The purification effect of fresh air does not depend on the number of filter layers. New wind system filter layer too much, but will bring counterproductive effects, such as the more layers, the wind resistance is also the greater, which will affect the air volume of the new air, noise, energy consumption problems will arise, in addition to the later replacement of the filter cost is also the greater, which invariably increases the unnecessary costs, these issues greatly reduce the later use of the experience.

Consumers form this false perception, a large part of the reason from the business, in the new wind market, many businesses to highlight their own product "advantage", claiming that their products are equipped with a 6-layer filter, 8-layer filter, etc., purification effect of the industry's first level, as soon as I look at it does feel that the product purification ability is very powerful, but in fact only a gimmick to attract consumers to buy. To attract consumers to buy gimmicks only.

Generally speaking, it is sufficient to have primary filters, intermediate filters and high efficiency filters in the new air conditioning system.

Each layer of filters has its own role and effect, and together they form a complete purification module. Choose the right number of filter layers for optimal filtration.

primary filters

Primary filter, the first layer of the new air system system, the main function is to intercept dust, hair, dander, large particles of pollutants, but also the new air purification system is the most easily dirty layer of filter.

Most of the primary filter in the material using a variety of specifications of wire mesh, non-woven fabric and other materials, these materials have an advantage, can be cleaned directly with water, greatly reducing the cost of replacement in the late stage.

medium efficiency filter

Medium effect filter, can intercept small particles in the air, such as pollen, dust, which uses folded filter cotton as the material, large filtration area, dust capacity is larger, the dust particles flowing into the air are effectively blocked by the filter material between the pleats and folds, can effectively filter particles in the air of more than 5 microns.

High Efficiency Filter

High-efficiency filters, many new wind brands of high-efficiency filters will choose HEPA filters, to meet the HEPA standard filter, can filter most of the 0.1 micron to 0.3 micron dust, HEPA mesh is characterized by the air can be passed, but the fine particles can not pass.

HEPA filters are the most effective in filtering PM2.5 particles, and they also capture mold, bacteria, and viruses, which can be said to be the heart of the filter.

In a nutshell, the outdoor air is filtered out of large particles and other pollutants in the air through the primary and intermediate filters, and then filtered out of fine particles such as PM2.5 through the high-efficiency filters, and then the activated carbon filters are used to adsorb harmful gases such as formaldehyde and odors in the air, so as to make the indoor air achieve a certain degree of cleanliness.

As for the purification rate, it depends on the material of the filter and the professionalism of the new air technology.
