KNOW YOUR AIR PURIFIER
When using the air purifier for the first time, we recommend that you use a higher fan speed,
such as speed three (3) or Turbo (T), for at least two hours to quickly clean the room’s air.
Then, we recommend that the air purifier run continuously on speed two (2) or three (3) to
maintain air quality, or for BreatheSmart 45i, set your unit to Auto mode.

CARE & MAINTENANCE
Cleaning Instruction
To avoid scratching the control panel, do not use abrasive/caustic cleaning solutions or
scrubbing pads. With the unit unplugged, dampen a clean towel lightly with soap and water
to clean the control panel, then dry gently with a soft cloth or paper towel. Glass cleaner
(e.g. Windex) is also OK. To avoid damaging electronic components, DO NOT allow liquid
to seep into the unit
Prefilter Cleaning
The black mesh layer on the front of the filter, known as the Prefilter, captures large dust and
hair. This layer is held on with Velcro®-like strips. This Prefilter can be vacuumed in place
to maintain efficient operation of the unit. You can learn more and purchase replacement
prefilters here.
