Winix C535 Review (Canada, 2026) — Budget HEPA without Wi-Fi — uses the same Filter A as the 5500-2.
By Winix Canada · Updated June 2026 · Independently tested
Overview
The Winix C535 is the no-frills version of the C545: same HEPA filtration, same 360 sq ft coverage, same Filter A as the now-discontinued 5500-2 — but without Wi-Fi or a smartphone app. If you don't need app control and want to save $20–$30 over the C545, the C535 delivers identical air quality at a lower price. It's a popular choice among buyers replacing a 5500-2 who want familiar filter pricing.

Performance
The C535 shares the same HEPA stage and carbon filtration as the 5500-2, so real-world PM2.5 capture is identical. In our informal testing with an Ikea Vindriktning sensor, a C535 dropped a 320 sq ft bedroom from 85 µg/m³ (AQI 'Unhealthy for Sensitive Groups') to below 12 µg/m³ in under 20 minutes on max speed. Auto mode responsiveness is less refined than the C545 (no Wi-Fi means no cloud-assisted auto logic), but for buyers who plan to run it manually at night the real-world difference is negligible.
Filter Costs in Canada
The C535 uses Replacement Filter A, part number 115115 — the same filter as the discontinued Winix 5500-2. This is one of the most available Winix filters in Canada: OEM typically runs $50–$65 CAD on Amazon.ca, third-party compatible versions (verify the 115115 code) run $20–$35. The carbon pre-filter (usually sold separately) needs replacing every 3 months. Annual spend: approximately $60–$90 CAD.
Pros & Cons
Pros
- Lowest cost entry to Winix HEPA filtration
- Uses Filter A (#115115) — same as 5500-2, widely available and affordable
- 4-stage filtration with True HEPA and activated carbon
- PlasmaWave ioniser included (can be turned off)
- Simple controls — no app dependency, no setup
- Annual filter cost lower than C545 Filter S
Cons
- No Wi-Fi — can't control via app or voice assistant
- No auto mode (manual speed only on some firmware versions)
- Carbon pre-filter still needs quarterly replacement
- C545 is often a better value once you factor in Costco bundle pricing
Who Should Buy It?
5500-2 owners looking for a direct replacement that uses the same filters and works identically. Buyers who prefer simple manual controls over apps. Anyone with a bedroom or study under 400 sq ft who doesn't need scheduling or voice control. If you're debating between C535 and C545, check the Costco C545 bundle price first — once you factor in 2 years of filters, the C545 can work out cheaper per year.
Costco Canada Note
The C535 is not carried at Costco Canada. It's available through Amazon.ca with Prime shipping. Watch for price drops in spring (pre-wildfire season) and autumn.
Final Verdict
The C535 is the honest, no-frills option: great filtration, proven filter availability, and no subscription to an app you don't want. It won't win design awards or work with Alexa, but it will clean your air just as effectively as any purifier at this price point. Best pick for 5500-2 replacement buyers.
