FREQUENTLY ASKED QUESTIONS
My filter bar says my filter is still relatively clean but when I checked my filter, it was really dirty.
In conditions where smoke, pets or air with a lot of contaminants are present it is possible that the filter
could be dirty sooner than indicated on the indicator. The filter life indicator on your unit runs on a timer
and if there are more particles in your air than in an average home, your filter could capture airborne
particles sooner than indicated on the display. The indicator is intended to be used as a guideline and
individual environmental conditions will vary.
My unit will not turn on.
The air purifier has safety features to ensure that the unit is ready for operation. Check to make sure
both True HEPA filters are installed flush to the air purifier. Check to make sure the rear cover is
installed flush with the unit and is locked.
When do the UV bulbs need to be replaced?
The "Replace UV Bulb" message and light will turn on after 6-9 months of continuous use, so the bulbs
should be replaced at this time.
My Air Purifier is starting to make noise and the air output is less. What's wrong?
The filters may be dirty. High amounts of contaminates can block the pores in the filter and stop the air
from moving through it. The filters should be cleaned or replaced.
How long should I run my Air Purifier?
For best results, you should operate your Air Purifier 24 hours a day when possible. This unit will be
more effective when doors and windows are closed.
Can I wash my True HEPA filter?
No. Washing the True HEPA filter will destroy it.
How does the electronic filter check work?
The filter check LED will change from green to red when it is time to check the filters after 3 months of
continuous operation of the air purifier.
How does the UV check light work?
The UV check light will change from green to red when it is time to change the UV bulbs. Follow the
instructions located in "Replacing the ultraviolet (UV) bulbs".
