Due to COVID we are having trouble getting filters from our suppliers as there is a national filter shortage. There will be a delay in getting the filters to you, and we do not know at this time when we will be able to ship them. Please call the office at 303-423-1982 for more information.

Replaces the PhotoHydroIonization (PHI) cell in a GuardianAir Air Treatment System.

(This can only be used if you have a GuardianAir PhotoHydroIonization (PHI) Air Treatment System.)

(We recommend a PHI cell change every three (3) years.)
