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.
Very
Breathable
The electrostatic filtration is low-resistance and allows for increased breathability.
Electrostatic
Filtration
By utilizing electrostaticaction, the filter captures particles in the air which lowers the amount of contaminants you breathe.
Fiberglass
Free
Our filters are fiberglass free, so you do not need to worry about irritation on your face.
Electrostatic Filtration Performance
The high-efficiency filtration fabric has at least the following characteristics. It is the same filter media used in ~90% of US ventilators. It offers exceptional breathability with much safer filtration than most available cloth mask filters.
