How often do I replace them?
- True HEPA filter: every 12 months under normal use.
- Activated carbon pre-filter: every 3 months — sooner if you run the unit 24/7 during wildfire season.
- Washable pre-filter mesh: vacuum it monthly and you're good.
Costco Canada tip
If you bought your Winix as a Costco bundle, you probably have a year (or two) of filters already in the box. Check the back panel — Costco bundles often include the next year's HEPA stack hidden under the unit.
Not sure which Winix you own?
The model number is printed on a sticker on the back of the unit, just above the power cord. Once you've got it, find it in the table above and grab the matching filter.
Winix 5500-2 Replacement Filter (Filter A — #115115)
The Winix 5500-2 uses Replacement Filter A, part number 115115. This is one of the most popular Winix filters in Canada and the USA — the filter also fits the Winix C535, making it easy to find.
Important note: the Winix 5500-2 has been discontinued in Canada. However, Filter A (#115115) remains widely available on Amazon.ca and will continue to be for years. If your 5500-2 is still running well, keep using it — the filtration is identical to newer models. When you're ready to upgrade, the Winix 5510 is the direct replacement.
Winix C545 Filter (Filter S — #1712-0100-00)
The Winix C545 uses Replacement Filter S — a combined True HEPA + activated carbon filter. Replace the HEPA layer annually and the carbon pre-filter every 3 months. The C545 is Canada's most popular Winix model and its filters are consistently in stock on Amazon.ca.
Winix 5510 Replacement Filter (Filter H — #116130)
The Winix 5510 — the 5500-2's successor — uses Replacement Filter H, part number 116130. Unlike the C545's impregnated carbon, the 5510 uses a pelleted activated carbon filter for significantly better odour control. Replace the HEPA annually; replace the carbon pre-filter every 3 months.
