Air purifier filter replacement guide

A HEPA chassis is only as good as the media inside it. After a smoky week, pre-filters load first. Match the exact model code, then prefer Ships from Amazon / Prime so you are not waiting on a grey-market pack.

Intervals below are manufacturer-style stubs. Smoke, cooking, and pets shorten them. Verify the SKU printed on your current filter against the Amazon.ca title. This is not medical advice — a dirty filter just moves less air.

Buying rules

Search the model printed on the old filter, not just the brand name.
Prefer sold-by / ships-from Amazon. Off-brand media can leak around the frame and quietly kill CADR.
After a heavy smoke event, change earlier than the calendar says if the pre-filter is grey and the unit is louder at the same speed.
Winix 5500-2 owners: confirm Filter H (116130) vs Filter A (115115) on the label in the unit before you order. We link H as the 5500-2 OEM path and mark it VERIFY.
