Marijuana Air Purifier for Smaller Rooms

We have sold many of these units for use in smaller rooms and offices. It works best in enclosed spaces less than 20′ x 20′.  5 ACH (air changes per hour) can be expected with the setting on high. The electrostatic filter can be washed in most standard dish washer. The cleaner the filter the better job it will  do on removing smoke from the air. The radial fan design is quiet enough to watch TV in the same room with the unit on high.

Carbon plus Zeolite = Cannablend

Cannablend is a blend of activated carbon and potassium permanganate impregnated zeolite. Zeolite has been used for years for absorbing impurities in water. Crystalline Zeolite also works well to remove certain odors. Acetic based odors like the ones produced by smoking marijuana is easily absorbed. When zeolite is treated with potassium permanganate it works especially well.  LakeAir does not charge more for a cannablend compared to straight activated carbon. Your Cannablend filters should last 3-6 months with ordinary use. Extra  smoky environments may require more frequent Cannablend filter changes. The replacement cost of the Maxum Cannablend Filter Part #499158 is $49.50 plus shipping. You can purchase a 4 pack of these filters for $180.00 with free shipping.
