Indiana Face Mask is a family-owned and operated company that believes in doing things the right way, not the easy way. That is why every part of the respirators are manufactured and assembled in their state-of-the-art factory. Producing every part of their respirators here in America ensures a high level of quality control, coupled with an incredibly low price — making the IFM A105 one of the most affordable NIOSH-certified N95 respirators available.  Each box contains 25 individually wrapped masks.   One size fits all...but, we've found that these masks are ideal for smaller head sizes. We also offer a 100% guarantee if the straps break, no questions asked. If you have a larger head, we recommend the Shawmut N95 mask.
