KN95 Face mask

MOQ:10000pcs

Certificate: CE FFP2

It is recommended that you buy the KN95 mask of GB2626-2006. On the one hand, this mask has a good protective effect and can be used for three to five days. On the other hand, please leave the medical surgical mask (general surgery) and GB19083-2010 medical grade N95 mask (for virus infection treatment) to the frontline medical staff. The effect of textile liquid splashing is most important to them. Ordinary people can prevent airborne transmission (light discharge from patients with droplets).


The reason why doctors use only GB19083-2010 is because this is produced in accordance with medical standards. It has the effect of blocking blood and splashing a large amount of liquid. It is enough for ordinary people to buy KN95 masks of GB2626-2006. Ordinary people mainly prevent airborne transmission (droplets in the air or slight discharge from patients)

Air filter

compressed air filter
1). Separator filter (HF9)
For bulk liquid removal plus a 3 micron coalescer (5ppm w/w maximum remaining oil content)
Two-stage filtration
* First stage: two stainless steel orifice tubes provide 10 micron mechanical separation
* Second stage: in-depth fiber media captures solid and liquid particles to 3 micron

2). Air line filter (HF7)
For removal of liquid water and oil; removes solid particles to 1 micron (1.0 ppm w/w maximum remaining oil content)
Corrosion resistant inner and outer cores
Two-stage filtration
* Firt stage: captures larger particles with alternate layers of fiber media and media screen
* Second stage: coalesces aerosols and captures solid particles with multiple layers of epoxy bonded, blended fiber media

3). High efficiency oil removal filter (HF5)
For coalescing fine water and oil aerosols; removes solid particles to 0.01 micron (0.01 ppm w/w maximum remaining oil content)
Corrosion resistant inner and outer cores
Two stage filtration

* First stage: multiple layers of bonded, blended fiber media for fine coalescence

* Second stage: multiple layers of bonded, blended fiber media for fine coalescence
Outer coated, closed cell foam sleeve

4). Ultra high efficiency oil removal filter (HF3)
For coalescing ultra-fine oil aerosols; removes solid particles to 0.01 micron (0.001 ppm w/w maximum remaining oil content)
Corrosion resistant inner and outer cores
Two stage filtration
* First stage: coated, closed cell foam sleeve acts as pre-filter and flow disperser
* Second stage: multiple layers of matrix blended fiber media for ultra-fine coalescence
Outer coated, closed cell foam sleeve

5). Oil vapor removal filter (HF1)
For removal of oil and hydrocarbon vapors normally absorbable by activated carbon; removes solid particles to 0.01 micron (0.003 ppm w/w maximum remaining oil content)
Corrosion resistant inner and outer cores
Two stage filtration
* first stage: stabilized bed of finely divided carbon particles removes the majority of the oil vapor
* Second stage: multiple layers of fiber media with bonded micro fine carbon particles remove the remaining oil vapor
Multiple layers of fine media prevent particle migration
Outer coated, closed cell foam sleeve prevents fiber migration
Designed life is 1000 hours under rated conditions.
