Face Mask Filter Insert
Improve the effectiveness of your current cloth mask with this high-efficiency, trim-to-fit filter. Our Medical Grade filter material is used in ~90% of US ventilators and tested to 99.99975% Viral Filtration Efficiency.
Trim-to-Fit Your Mask
Ideal filter for masks with pockets
Just trim the filter to fit into any mask. Insert the cloth mask filter into the pocket and start feeling safer and better protected against airborne contaminants.
The electrostatic filtration is low-resistance and allows for increased breathability.
By utilizing electrostaticaction, the filter captures particles in the air which lowers the amount of contaminants you breathe.
Our filters are fiberglass free, so you do not need to worry about irritation on your face.
