Changing the Filter for the BreatheSmart 45i

The Filter Life Indicator, located just above the FILTER button, consists of three lights: Green (left), Yellow (center), and Red (right).

The Green light will be illuminated for most of the life of the filter. The Yellow light will come on shortly before your filter should be replaced. Note that this is the ideal time to order a new filter. Once the Red light is illuminated, it is time to replace the filter. Though light may remain green for some time, we recommend regular filter replacements (at least every 9-12 months with normal use) to extend the life of your air purifier and maximize performance.

To replace your Filter & reset the indicator, follow these steps:

1. Remove cover. Pull firmly on the cover near the top of the intake vents with both hands to release the magnets.
2. After pulling the cover out, lift it away from the unit.
3. Remove the used filter by pulling out on the ribbon loop.
4. Place the used filter in a plastic bag to prevent dust from re-entering the air.
5. Take the new filter out of the plastic bag and insert it into the purifier with the ribbon loop facing outward. (The front side has the black foam layer, known as the prefilter, which should be facing out when inside the purifier, insert into the air cleaner with the arrow pointing inward.)
6. Insert the bottom hooks on the front cover first and then the upper part of the cover will snap into place.
7. Hold the FILTER button down for approximately 5 seconds while the unit is turned on. The Red light will then be reset to Green.
