Frequently Asked Questions


How do I know the masks are effective?

O2SafeAir has been designed using an ergonomic facial fit in 4 sizes with insertable filters that have been tested for filtration efficiency against international performance standards at Nelson Laboratory, Utah, USA. Our filter test results are available upon request.


What certifications are the filters tested against?

Our air pollution filters are tested against and conform to NIOSH N95 filter efficiency for airflow resistance and particle filtration for requirements of an N95 respirator. They average filtering 98% of particulates down to a size of .3 microns with extremely low breathing resistance. Our medical grade filters are tested and conform to medical professional standard ASTM F2100-11 level 2 and block over 99.99% of airborne bacteria to a size of .1 microns with extremely low breathing resistance.


How long can filters be used before they need to be changed?

For our air pollution filters, while the filter should be effective for up to 50 hours of usage, as pollutants will build up or "load" inside the filter over time increasing breathing resistance and due to recommendations by NIOSH for the usage guidelines of N95 rated respirators, we don’t recommend using them for more than 8 hours before replacing them. For our medical grade filters, given the purpose of filtering out airborne pathogens and microorganisms, we recommend changing with every use. To ensure optimal performance, you should change filters after each usage.


How do I properly insert the filters and wear the mask?

As filters are sized to match the mask they are used with, ensure the filter and mask sizes match. Open the flaps in the back of the mask, line up the middle of the filter and ensure the top and bottom of the filter are touching the inside perimeter of the inside top and bottom of the mask. Next push the sides in and adjust to ensure the filter is aligned around perimeter inside of mask without "bunching" before closing the flaps.


What makes O2SafeAir unique or better than other masks?

O2SafeAir is the culmination of 4 years of R&D and market feedback from our first product. Key differences vs. other masks are that O2SafeAir is the first 3 step mask system which you can personalize for your needs by selecting different filters for different environments. We have also worked hard to find and source the best possible filter technology providing not only optimal protection but breathability and comfort. Our proprietary materials and design also raise the bar on stylish protection!


What don't the masks protect against?

Our filters are not designed to protect against harmful gases, asbestos, silica, or spray paint. They are not recommended for occupational usage. As we are able to grow as a company, we have plans to introduce additional filters to protect against gases, ozone, and other specific airborne threats as well as to pursue regulatory certifications for occupational and medical professional usage.


Why don't O2SafeAir masks have exhale valves?

We have employed a proprietary fabric and filters in our masks that ensure ease of breathing. Some masks need exhale valves because it is difficult to pull air through and so humidity quickly builds up and needs to be released. This provides a problem if the purpose of the mask is to protect those around you from your germs since you are releasing them through the exhale valve whereas with O2SafeAir you are breathing in and out through only the filter.


Are the masks machine washable?

Yes! This is a large improvement we wanted to make from our first version mask, which had a sewn in filter and machine washing would reduce the filter efficiency. Given that filters have electrostatic properties, washing a mask with a filter inside will diminish its performance. O2SafeAir makes it easy to machine wash your mask, which has been tested to ensure color won't fade and the material is quick drying, and then just pop in a fresh filter before your next use and hygiene is ensured!
