2. The hepa filter is a high-efficie

ncy fi

lter. Due to the small air volume of t

old fan, there i
s only a sm
all amount of air. Through the filter, m
ost of the wind is bounced back, wh
ich does not affect the filtration efficiency, but only affects the filtration speed.
It is recommended to
use a 10-inch ce

ntrifugal exhaust fan   [About the odor] Since the filter is filtered in a wave-like shape, in order to stabilize the filter material, ensure the spacing of the fold layer, and ensure the stability of the filter material. Keep appropriate airflow through the filter, so the filter is injected with separator between each fold. This is hot melt adhesive, which is It is safe and non-toxic. It smells a little when the new product is opened. This is normal!   [About the number of folds of the filter] Theoretically, the more folds of the filter paper, the larger the spread area, the effect The better, but too many folds will cause insufficient space in each fold of the filter, which will create a larger wind It affects the actual purification effect, so the number of folds on household air cleaners is generally between 75-80. ############ Purchase Notes: (1) This store sincerely serves every purchaser.
