Why is the check filter light blinking on my Asept-Air Air Cleaner?
- WwilliamshahAug 3, 2025
If the check filter light is blinking on your Asept-Air Air Cleaner, it could mean one of two things: either the unit has been in use for 3,000 hours or more since the last timer reset, in which case you should check, clean, and replace the filters; or the timer needs to be reset. To reset the timer, press and hold the FAN SPEED + and TIMER - buttons on the front panel until the unit chimes once.
