Vacuum cleaner filter introduction

Haipa is a foreign name. It is an efficient vacuum cleaner filter that can block very small dust, with an efficiency of 99.97%. Its air permeability is low, so it is made into a wave shape to increase the ventilation area. Some of this filter material can be cleaned repeatedly. Any filter material has a "life", that is, the pores of the filter material have been blocked by small particles of dust after long-term use. Therefore, paper dust bags are ideal, disposable, sanitary and convenient. After the cloth filter bag is cleaned, the fibers will be compacted, which affects the filtering effect and the ventilation effect. The SMS three-layer composite filter material is washable, but the air permeability is slightly lower.
