multiple sizes to allow for better fifit and protection. It also tends to be much easier to fifit test than a disposable respirator.
From an environmental standpoint, they are a better option than the disposable respirator as they tend to create less waste with their reduced fifilter consumption.
There is really only one con for the Reusable N95 Half Mask Respirator: the fact that it requires cleaning and maintenance.
Ultimate Protection—If You Require
Protection Above APF25
Reusable Full Face Mask Respirators.8 From .5 mg/m3 to 2.5 mg/ m3 TWA for 8 hours, requires a NIOSH approved full-facepiece respirator equipped with an N-, R-, or P-95 filter or higher with an Assigned Protection Factor (APF) of 25. (Full Face Respirators provide an APF or 50.)
For the Reusable Full Face Mask Respirators, there are many pros, which include a new special composite silicone material that offers superior comfort and value. NIOSH has certified this respirator as a universal size, which can help to reduce inventory. These respirators also tend to be easy to fit test before entering a hazardous work zone.
The Reusable Full Face Mask Respirators have a protective lens cover that helps to prevent scratching and the length of product life. These respirators tend to be the economical choice as they often are less expensive than powered air purifying respirators
and require less turnover in products, reducing waste for the company.
Cons of the Reusable Full Face Mask Respirator are in line with the con of the N95 Half Mask: it requires regular cleaning and maintenance from the wearer and company who supplies it to their workers.
