What are the general types of filters for new air conditioners?

There are three types of filters, primary filters, high filters, charcoal filters,

Primary filters, usually made of non-woven fabrics, nylon mesh, metal holes in the mesh of these materials to produce, the function is to filter out the role of larger pollutants in the air particles. Advantages of the main can be repeated for use, easy to clean.

High filter, usually also known as HEPA filter, the main material for the PP filter paper, fiberglass, composite PP PET filter paper composed of a high filtration purification of air material, can remove the air diameter of 0.3 microns below the tiny particles, and does not produce harmful gases, the disadvantage is that the later need for regular replacement of filters, which will produce a certain amount of cost of use. The other is a kind of new wind machine of the labor force special this kind of use electrostatic dust purification air, the air through the negative ion electrostatic dust collector, H13 filter purification after sending into the room.

Charcoal filters, the use of through-hole structure of the aluminum honeycomb, the advantages of having a better gas dynamics performance, large surface area, good adsorption. Can adsorb a variety of pollutant gases in the air, but also has a good role in removing odors. The disadvantage is the use of a certain period of time is also the need for maintenance, maintenance needs to be placed in the sun for sun exposure, sun exposure can be repeated after use.
