6 Face Mask Filters
These are PM2.5 Filters, which are made out of activated carbon and non-woven melt-blown filter cloth. The 5-layer filter system effectively keeps away a range of airborne contaminants.
Compatible with i-Blu face masks, easy to insert or replace the original one.
Most fabric face masks should be worn with an additional filter in order to effectively protect against airborne contaminants.
Each filter can be washed up to 10x. Hand wash recommended, no tumble dry, hang dry only.
