Whole-house air cleaners, media filters, filter cabinets, conversion kits and replacement parts from Resideo.
A media air cleaner is a four- to five-inch deep cabinet holding a pleated filter, and the depth is the whole advantage. The extra surface area captures finer particles at a lower pressure drop than a one-inch throwaway, and it lasts six to twelve months instead of thirty days.
Pressure drop is the specification most often ignored. A high-MERV filter in a system not designed for it starves the blower, which shows up as reduced airflow, longer run times and, on a furnace, high-limit trips. MERV 11 to 13 is the usual practical ceiling for residential equipment; higher belongs with a blower sized for it.
Retrofitting a media cabinet needs physical space at the return plenum, and that constraint decides most jobs before filter choice does.
Electronic air cleaners work differently — they charge particles and collect them on plates that are washed rather than replaced, so the running cost is labor instead of filters.
