Are n99 masks better than n95?

N99 air masks can filter up to 99% of the particulate matter 2.5 from the air. Just like the N95, they don't work well against oil-based pollutants, but are better than the former because of the higher filter rate of particulate matter.

Beside this, what is the difference between n95 and n99 masks?

The difference between an N95, N99 and N100 respirator is simply the filter's efficiency level (i.e. N95 = NOT Resistant to solids and liquids which contain oil and provides 95% efficiency). The higher the efficiency, the more particulates the respirator will filter out.

Also, how long does n99 mask last?

How long can you wear a disposable mask? The N95 and N99 respirators are disposable masks which should be discarded after 2-3 days.

Can n95 mask be washed?

When to Throw Out the N95 Mask
A deformed mask may not fit properly. An N95 mask cannot be cleaned or disinfected.

When should I change my mask?

Change your mask when it becomes wet, soiled or damaged, or if you have difficulty breathing. Secure on head with ties and/or elastic and adjust to fit. Wash your hands after removing your mask. Perform a fit check by inhaling and exhaling.
