What is the difference between positive and negative pressure in a mask?
Negative pressure respirators, like the common N95 mask, rely on the wearer's inhalation to draw air through a filter. On the other hand, PAPRs are advanced systems. They use a powered fan to intake surrounding air, filter it, and deliver clean, breathable air to the user.Apr 29, 2025

What pressure checks should you perform to check the fit of your respirator?
During a negative pressure user seal check, the respirator user inhales sharply while blocking the paths for air to enter the facepiece. A successful check is when the facepiece collapses slightly under the negative pressure that is created with this procedure. A user seal check is sometimes referred to as a fit check.

What is the difference between EN 149 and EN 143?
EN 143 defines the standards for respiratory filters, such as those used with re-usable air-purifying masks: EN 149 defines the protection standards for respiratory filtering half masks. This standard generally applies to disposable masks.
