Product name: N99 Melt blown Respirator filter Cloth
PRODUCT DESCRIPTION:
This filter cloth is fit for the production of N99 standard personal care respirators which has a minimum efficiency of 99.5% and a maximum resistance of 95 Pa. It can provide superior protection from PM 2.5 particles, dust, pollen, and other airborne contaminants.
THe N99 filter material is specially good at its low penetration pressure and its duct collect capacity. Very good to be used as different type personal respirator production, like 3 ply face mask, cup shape mask etc.
Basis weight: 80gsm
Filtration Efficiency: > 99.5%
Air resistance: < 95 Pa
Roll width: 90mm - 1600mm
Roll Length: 500 - 1000 meters
US N Serials (NIOSH 42 CFR-84 & GB 2626-2006)
| Standard | GSM | Resistance (Pa) | Filtration efficiency (%) | MAIN USAGE |
| N 90 | 30 | < 60 | >93% | Economic product, lower cost |
| 60 | < 40 | >95% | bulky and soft product, lower air resistance, higher dust capacity
|
| N 95 | 30 | < 90 | >98% | lower basis weight of N 95 standard respirator filter media, economical and practical product |
| 50 | < 60 | >98% | N 95 standard respirator, fit for mine, severe air condition workshops etc |
| 80 | < 50 | >98% | Bulky and soft product, lower air resistance, higher dust capacity |
| N 99 | 80 | < 95 | >99.5% | N99 standard respirator, cup shape mask. |
| N 100 | 120 | < 145 | >99.995% | N100 standard respirator, very high filtration efficiency |
Marks: This N99 product can reach to 99.5% filtration rate with the air resistance less 95Pa. The parameter is obviously better than N99 standard requirement, 99% filtration rate and 120Pa resistance. Same performance is shown in the standard of N90, N99 and N100 products.
