Serious Cannabis Smoke and Odor Control

The key to controlling weed smoke and its odor is heavy duty filtration. The Maxum-HEPA-420 offers commercial a grade True HEPA filter (made in the USA by Glasfloss). The Cannablend filter is commercial grade and is manufactured in our plant in Racine Wisconsin. The Blower is from Zeihl-Abegg a well known German air handling equipment giant.  This three way combination make the ultimate weed air purifier. The Maxum-HEPA-420 is one of the great values in the LakeAir Smoke Eater Line. 

Energy Cost Efficiency and Sound Control

Depending on the speed chosen, the Maxum-HEPA-420 costs between 58 and 22 cents a day to run (24 hours/day) That’s roughly 120 – 6 watts. About as much as many lightbulbs. The variable speed controller allows you to set the fan speed to a level that fits the desired environment. The unit is sear silent on low and can reach as loud as 68 dB(A) on turbo. The efficiency of the filters will allow you to run your weed smoke eater well below the turbo setting.

The Cannablend Difference

Cannablend is a blend of activated carbon and zeolite that has been impregnated with potassium permanganate . Zeolite is a naturally occurring crystal that has natural absorbing properties. It is used in filtering both water and air. By adding potassium permanganate this compound becomes a pot odor magnet.   There is no extra charge for this special blend of odor absorbers. The filters should last 3-6 months with standard use. Heavy smokers may have to change filters more often.
