The 8233 N100 Particulate Respirator is for those who want NIOSH's highest rated filter efficiency in a maintenance-free mask. The N100 rating indicates that this mask is 99.97% effective against particles .3 microns and larger. Each mask is individually wrapped to prevent contamination.
Approved for lead abatement, metal fumes produced from welding, certain radioactive particulate material and non-oil containing mists. Recent recommendations from the CDC include avian flu and swine flu, though N95 masks are also recommended, and may be just as good and a whole lot cheaper.
The Cool-Flow exhalation valve helps keep the mask cool and dry. A soft inner face seal conforms to your face, offering a better than average seal for a disposable mask. Not approved for asbestos.
This mask has been a popular choice for protection against avian flu, swine flu, tuberculosis / TB, and SARS.
The 3M 8233 Respirator compares to the now discontinued 9970 Respirator. The 9970 mask was rated as a HEPA filtered mask. Since then, NIOSH has changed this designation to either N100 (no oil) or P100 (resists oil). Another cross would be to the 3M 8293 Mask, which carries the P100 rating. We don't stock that mask, but it can be ordered by request.

Respirator Review by jeterla
Easy to use, as comfortable as any other respirator.
"Easy to use comfortable"
Little pricey per unit

A product that fits and works well. Review by Smithbrother
"The above described dust mask breathes even easier that the N95 one made by the same 3M company.
Although the allergy season was almost over I was glad to have found the product ."

The 3M 8233 HEPA respirator mask could certainly be worn while sleeping. It would be best if you were sleeping on your back, as the mask should cause no interference in that position. Sleeping on your side may work as well. That will be more dependent on what type of pillow you are using. For instance, a great many people are able to use CPAP machines in just such a scenario. The thing to keep an eye on is the face to mask seal. The filtration efficiency of the 3M 8233 would be wasted if the mask was not making a good seal.
The answer is that it depends on the environment you’re using them in. Disposable masks like the 8233 or filters like the 2097 and 7093 block particles, and they don’t stop blocking particles as they get used. But like a colander that gets clogged, less and less air can make it past the mask, and you’ll notice it is harder and harder to breath. If this happens, you’ll know when it’s time to change out the filter.
If you don’t have that much dust or particulate matter floating around, the filters that attach to a reusable respirator mask (the 2097 and 7093) will last for several weeks if kept clean. The 2097 has a layer of activated charcoal to remove bad smells, and that can be rendered useless even in ambient air if it is exposed to things like fumes from paint thinner. Store them in a plastic bag to extend their life.
The disposable 8233 can be used for about a week as long as no damage occurs to the face seal and it doesn’t become hard to breathe through.
