Welcome to MASK FAQ

How well do homemade mask materials filter compared against the N95 standard?

MASKFAQ tested 100’s of media/materials and posted results, using the NIOSH certification standards.

All material testing was conducted by senior engineers at TSI Inc.

The TSI 8130a is the instrument that certifies the N95 respirators and provides the most consistent and accurate test results available for both filtration and resistance. The information we are providing is based on research and is updated when new data surfaces.

Our Mission

To share accurate, science-based information regarding the filtration capabilities of everyday materials that can be used in a DIY face covering.

To offer a cost-effective solution, aka the DIY mask, to help keep people safe and to mitigate the spread of COVID-19.

Disclaimer

We do not claim to be experts of filtration media for homemade masks. The goal of this project is simply to obtain and share the best possible filter information for commonly available homemade mask materials. MaskFAQ did not conduct any testing mentioned on this website and the results were provided independently to us at no charge courtesy of TSI, Inc. The test results are provided for informational purposes only and do not take into account mask fit or real-world usage, should not be interpreted as recommendation or advice, and are not approved by any regulatory agency. We cannot give any guarantees to the safety of any of the materials tested.
