The first effect is to filter large particles of dust, batt, insects, etc., the first level of health guards.
The golden ratio pleating process, the open structure increases the amount of filtration per unit area,
The purification efficiency greatly increases the wind resistance and can effectively reduce the wind noise.
At the same time, it has high efficiency and air permeability.

High quality aluminum foil cast heat exchange core, durable, washable, free of life
Replacement, good sealing, low air mixing rate, no moving parts,
Never mold, avoid "secondary pollution", run more smoothly and reliably
At the same time, it can recover the energy of the temperature in the air, and the heat exchange efficiency is as high as 90% or more.

Using high iodine value modified activated carbon,
Bonded to the microporous filter steel network after chemical treatment,
The design principle is more scientific,
Adsorption capacity for small molecular impurities,
The adsorption rate is significantly higher than conventional activated carbon.
It can strongly adsorb volatile organic compounds such as formaldehyde, toluene, TVOC/total, and is not easy to desorb.
Using padding,
Increase the crushing resistance of activated carbon while increasing the adsorption area and reducing wind resistance.

European standard H13, can effectively remove μ-level particles
