1″ G4 Prefilter for AS500 Air Scrubber – 455x455mm

Prefilters for HEPA AS500 Air Scrubber – 455mm x 455mm Compatible with IAQ PRO AS500 & Phoenix Guardian R Agile Equipment sells 1 inch G4 pre-filters at dimensions of 455mm x 455mm for particular HEPA Air Scrubbers such as the IAQ Pro AS500 Air Scrubber.  These filters prolong the life of your primary H13 filters in your air scrubber by filtering 90% out the coarser particulates, of 10 microns or larger. Agile recommends visual inspections be made on pre-filters before and after use, to gauge filter life. Usage of filters may vary depending on heavy/light use. If the filter is quite visible on the filter, we recommend buying replacements. If you have any questions about prefilter sizes and compatibility, please ask us on the phone, on the website chat or in person. We are happy to have a chat.
