Activated carbon filters for adult masks are suitable for most cotton masks as these filters measure 12.5 cm wide x 8 cm high.
These activated carbon filters have 5 layers of filtration as you can see in the image below and offer the same protection as a surgical mask, an FFP2 KN95 mask.
The carbon filters that are sent to you can be put on and taken off very easily as the carbon filters should NOT be washed, they should be thrown away every four or five days depending on the use:
When film stains or sticky deposits appear, replace the filter
