[archived] MinusA2 Air Purifier - Benefits

The MinusA2 SPA-700A air purifier will filter all of the air in a room up to 700 sq. ft. (or 815 sq. ft. for the SPA-780A) twice in an hour on the high setting.

What is room coverage?
Room coverage is determined by Air Changes Per Hour (ACPH). An air change per hour translates to how many times an air purifier can clean a room in one hour. For example, 2 air changes per hour shows that an air purifier can clean a room once every 30 minutes.

An allergy and asthma sufferer needs at least 4 air changes per hour, which means an purifier can clean a room at least once every 15 minutes.

Auto air quality monitoring
The unit will automatically adjust the fan speed based on the air quality sensors.

When it senses particles or odors in the air, the machine increases fan speed.

The machine switches over to high speed until the air has been cleaned.

Once the sensor detects a reduction in airborne pollutants, the machine will resume its original speed.

Light sensing
A light sensor will automatically transition the unit to sleep mode when the MinusA2 is in a dark room, and resumes a more active mode when light levels increase.
