Frequently Asked Questions about face masks and respirators and our replaceable filter packs. This page is meant to answer all the questions our customer or potential customers would have about their purchase of a RDR mask or Aspen Air respirator. For detailed instructions on how to care for your mask, pleas see our care guide.

General Questions

All of our products are manufactured in the U.S.A. out of our manufactuering facilities in Utah.

Currently, the Aspen Air, Aspen Air Pro and BFE 98 filters are not FDA approved. We are being fast-tracked through the FDA approval process.

Currently, the Aspen Air, Aspen Air Pro and BFE 98 filters do not have a NIOSH certification.


Currently, the Aspen Air, Aspen Air Pro, and BFE 98 filters are not OSHA compliant as they do not have the FDA/NIOSH rating. At this time, there is no OSHA standard for Dentistry

Due to a global shortage in N95 masks, our products encourage the wearer to get multiple uses from their existing N95 (or other mask) supply. We do provide ASTM Level 3 equivalents, the BFE98s, for your convenience. All masks may be cut to size with our provided template.

Due to a global N95 shortage, these masks are incredibly hard to source and counterfeits on the market are common. Here are the CDC's recommendations on how to spot counterfeits: https://www.cdc.gov/niosh/npptl/usernotices/counterfeitResp.html

Place the mask over nose and mouth and secure with upper strap. Insert loose end of lower strap into the remaining hole and adjust as necessary. It should snuggly cup the chin with the top of the frame resting snug against the bridge of the nose.
When properly fitted and worn, minimal leakage occurs around the edges of the respirator frame where it seals to your face. Seal should increase when you inhale with almost all the air directed through the filter media. Upon exhalation, you should not feel air around the perimeter.
Ensure the bottom is cupping your chin and tighten straps producing an air tight seal.

Yes. The Aspen Air and Aspen Air Pro are great options for people who are allergic to Latex.

Filter Questions

The mask is versatile enough to work with any type of filter that can be cut to fit the mask. This makes it extremely useful for a number of medical, emergency, and household uses.
We do not currently carry filter refills at this time.
Since traditional N95 masks are made entirely of the filter material, our mask utilizes only a small portion of the actual filter, allowing you to cut out 5-6 additional filters from one standard N95 mask using our template.

We can not provide guidance regarding how often to replace filters. Please refer to the CDC's current recommendations based on use case and your current supply on hand.
