The Filter Life Indicator, located just above the FILTER button, is a light that can turn one of three colors: Green, Orange, and Red.

• The light will be Green for most of the life of the filter.
• The light will switch to Orange shortly before your filter should be replaced. This is the ideal time to order a new filter.
• Once the light turns red, it is time to replace the filter.

Though the light may be green for some time, we recommend regular filter replacements between 6-12 months (varies by filter type/uses) to extend the life of your air purifier and maximize performance.

To change your BreatheSmart 25i filter:

1. With the unit standing upright, pull firmly on the cover near the intake vents with one or both hands to release the magnets.
2. After pulling the cover out, lift it away from the purifier.
3. Removed the used filter by rotating the filter lock counter clockwise, and pulling out and down on the pull loop.
4. Place the used filter in a plastic bag to prevent dust from re-entering the air.
5. Take new filter out of the plastic bag, insert the bottom and firmly push the top of the filter frame until it as far back as it can go. (The window-like screen prefilter should be facing out when filter is installed.)
6. Rotate the filter lock clockwise to lock filter in place
7. Insert the bottom hooks on the front cover first and then the upper part of the cover will snap into place.
8. Once the purifier is powered back on, the Red filter light will then be reset to Green automatically.
