The Odor Tech contains an all-in-one washable pre-filter, activated carbon and exclusive MCP odor powder. This filter is designed for maximum odor removal and contains twice the amount of carbon as the BF25A filter for odor adsorption and twice the amount of MCP odor powder for smoke and bathroom odor removal. The MCP odor powder uses a patented molecular conversion process (MCP) to change smoke and most bathroom odors to be odorless on contact. The powder is a concentrated form of the technology that is used with the Alen odor sprays. There is no HEPA media in this filter so the life of the filter is 1-2 years. Filter is designed for use with the Alen A350 and A375UV air purifiers.

Odor Technology: Carbon - through adsorption, activated carbon acts like a sponge to hold in odors and some gases as they pass through the filter, effectively removing them from the air. Activated carbon pellets perform better than carbon pads due to an increased surface area and being a more porous medium.

MCP Smoke & Odor Powder. This exclusive concentrated powder uses a patented molecular conversion process (MCP) to change smoke and most cooking & bathroom odors to be removed on contact. This is the same product as in our odor sprays but in concentrated form to effectively eliminate odors as the air passes through the air purifier.
