The area of the filter, it is important to use data and filtering level.
Purification area, the greater the power, the better, the higher the power price is more expensive;
Power filter level is higher, the better, the higher the power, the more expensive, this is must.
Primary filter and use of information is one of the most important, must ensure that quality, because of the filter in thin, under the condition of the intelligent control wind speed.
Air quality will become a bad wind speed is high, the attenuation after purification filter can drop speed will be up to the peak of agile, has influence on motor and machine, also can send dirty air continuous to indoor, so to safety after use as the first condition.
Just consider to choose cost-effective.
May filter itself has the taste, filter mould will sour;
Also may be the environment out of the window is faulty, in the fresh air filtration time was brought in, see if there are any open window, if the window does not have prompt you should change the filter.
Household air systems tend to have four layer filter, respectively, the early effect, the effect and high efficiency filter and activated carbon filter.
Early effect filter: it is made from white non-woven folding, folding part opens, eyes area expanded several times, filter area is large enough.
As a function is to filter out the effect of the larger particles in the air.
As a primary filter, it can be useful to avoid large particles of dust in the air to enter the body.
Effect of mesh: light quality, appearance beautiful and pleasing to the eye, firm structure by using;
Use made of folded filter cotton, aluminum frame and agglutination, big filter area, more let dust, flowing into the filter information useful to block the dust particles in the air between the fold and fold, can be useful to filter more than 5 um particles in the air.
