Why it matters
The Wilerda Replacement Filter for MA Series 50W is a replacement filter.
Made for Wilerda's 50B 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 12.36 inL x 5.59 inW x 1.42 inTh.
