If you happen to own a mask that uses cartridge filters and a replacement PM2.5 filter, you will need to purchase filter replacements.
The MEDRACHEL Activated Carbon Filter Replacements come with 20 pieces and are PM2.5 filters specifically made for masks which have the filter cartridge on both sides of the face masks.
These are carbon filter, so once you have it on your mask, you will immediately smell the carbon, so its important to know that.
There are five layers of filter structure and the filter layer has activated carbon which can filter benzene and automobile exhaust. These are PM 2.5 so you have the non woven cloth, meltblown cloth, activated carbon cloth, meltbown cloth and again a nonwoven cloth layer.
They are breathable and have a waterproof design.
According to the company,
- The first layer of spunbond filters out micron-sized dust;
- The second layer filters industrial pollutants, car exhaust, second-hand smoke and pollen allergens;
- The third layer of activated carbon cloth filters out micron-sized dust;
- The fourth layer provides filter density for smaller materials;
- The fifth layer of spunbond filters out various harmful substances.
Overall, I have masks that utilize cartridges and I needed filter replacements, so these work perfectly. And at $7 for 20 filters, its definitely recommended!
