Electro Air Filter Replacement
Replacement filters for Electro-Air air cleaners: HEPA filters, carbon pleated prefilters, filter kits and sets of 2 or 3. Electro-Air uses part numbers such as DM900-0810, DMH4-0400, W4-0840 and 1156-3, so the fastest match is the number on your current filter or in your unit's manual.

Electro-Air filter guide: matching part numbers ▾
Match the full part number
Find the number on the filter frame or in the manual for your air cleaner model. Many Electro-Air numbers look alike, such as 69-0810 and 69-0855 or 58-0810 and 68-0810, but they are different filters, so match every digit of the prefix and the suffix.
HEPA filters and prefilters
HEPA air cleaners usually use a main HEPA filter with a prefilter in front of it. The prefilter catches larger dust and, in carbon versions such as the DM900-0855 and W5-0810, helps with odours. Prefilters are usually changed more often than the HEPA filter; follow the schedule in your manual and check them sooner in dusty conditions.
