Why it matters
The GeneralAire 12758-9 Replacement Filter is a replacement filter.
Made for GeneralAire's 12758-9 purifiers. The model label is usually on the back or under the filter door; match it before ordering.
Most purifier HEPA filters last six to twelve months in normal use; follow the unit's filter indicator and replace sooner in smoky or pet-heavy homes.
Use the filter made for your exact unit: purifier filters seal against their own housing, and a close-but-different filter lets air bypass the media.
The listing gives dimensions of 25 inL x 8 inW x 6 inTh.
