envo^® pro N99 Filters (25 ct.)

A filter may never be cleaned or reprocessed. Once you remove the filter from the mask, immediately discard the filter.

Condensation may occur when wearing the mask, which is normal. If condensation occurs, you do not need to replace the filter. Most of the moisture in your breath will escape through the filter of your mask. N95 and N99 respirators trap more moisture than cloth masks, but their filters allow enough air through so that a user can maintain a natural temperature. People experience temperatures differently, and some tend to be warmer than others. Our respirators cover up part of your skin that isn’t typically covered. Thus, this area cannot evaporate sweat and moisture, which may accumulate as you breathe out and moisture becomes trapped under the respirator.

If your respirator and filters have been subject to harsh environments, clean the respirators and dispose of the filters properly when finished. Never use a damaged respirator or a respirator with missing parts.

Please follow NIOSH N95 guidelines or consult your company’s safety officer. If the filter reaches maximum load and breathing becomes labored, immediately leave the contaminated environment then replace the filter with a new filter. If the filter material is physically damaged or soiled, you must discard and replace the filter. Always follow the guidelines provided by your company’s safety officer.

Here is an excerpt from the CDC website published by the National Protective Technology Laboratory (NPPTL).

The envo^® mask N95 filters are four layers, including proprietary fibers, making the envo^® mask one of the lowest resistant masks on the market. Lower resistance equates to easier breathability.
