Where is the best place to put my Air Purifier in a room?

Aeramax Personal: Units should be placed as close to the source of the contaminant as possible, where contaminated air can be drawn directly into the filtering system. Acceptable places to put you air purifier include, next to a desk, in the corner of a room, etc. The best places have 1-2 feet of free space around the product to allow for air circulation. It is NOT recommended to put your air purifier close to direct heat, a vent or a smell source (such as next to an air conditioner, a fireplace, a fan, etc.) The direct proximity of those could have an influence on the correct functioning of your unit’s AeraSmart™ Sensor.

Aeramax Pro: Units should be installed as close to the source of the contaminant as possible, where contaminated air can be drawn directly into the filtering system. Also, by placing the unit higher on the wall, close to the ceiling (always allow a minimum of 8” space from ceiling and top of unit) the unit’s powerful exhaust can circulate purified air throughout the room. The best places have 1-2 feet of free space around the product to allow for air circulation. It is NOT recommended to put your air purifier close to direct heat, a vent, or a smell source (such as next to an air conditioner, a fireplace, a fan, etc.) The direct proximity of those could have an influence on the correct functioning of your unit’s AeraSmart™ Sensor.
