Winix C610 Review (Canada, 2026) — Large rooms and wildfire smoke — quieter on auto.
By Winix Canada · Updated June 2026 · Independently tested
Overview
The Winix C610 is the upgrade pick for Canadians with larger open-concept spaces or anyone who runs their purifier 24/7 during smoke season. Its 360° cylindrical design pulls air from all sides — meaning placement doesn't matter — and its all-in-one filter only needs replacing once per year, not quarterly like the C545's carbon stage. The 2025 Costco Canada sale price of $159.99 (down from $189.99) made it one of the best air purifier deals in the country.

Performance
Independent testing by Breathe Quality placed the C610 at 99.9902% particle removal in a 200 sq ft room over one hour — ranking 4th among all Winix models tested, behind only the T810, T830, and 5510. For real-world wildfire smoke performance, the C610's higher CADR (252 vs 232 CFM) and 360° intake make it noticeably more effective in open-concept spaces where the C545 struggles to move enough air. The 22 dB sleep mode is the quietest in the Winix lineup.
Noise Levels
Measured at 3 ft. from the unit.
| Speed | dB Level | What it sounds like |
|---|---|---|
| Sleep Mode | 22 dB | Near-silent — best in class |
| Speed 1 | 28 dB | Inaudible at night |
| Speed 2 | 36 dB | Soft background hum |
| Speed 3 | 45 dB | White noise, suitable for living rooms |
| Speed 4 (Max) | 58 dB | Loud — use briefly for quick cleans |
Filter Costs in Canada
The C610 uses a single all-in-one Replacement Filter T (code: 1712-0116-00) that lasts 12 months. OEM filter on Amazon.ca: ~$60–$75 CAD. Third-party compatible alternatives: ~$30–$45 CAD. Because it's just one filter change per year (vs. C545's 5 changes per year), it's actually lower-maintenance despite similar annual cost.
Pros & Cons
Pros
- Quieter sleep mode than C545 — 22 dB (near-silent)
- 360° cylindrical design — effective from any position
- Annual all-in-one filter (not quarterly like C545 carbon stage)
- Higher CADR than C545 — better for open-concept spaces
- 4-colour LED air quality indicator
- Google Home + Alexa compatible
Cons
- Turbo mode is loud — 58 dB sounds like a jet engine
- Some units reported bearing failures around 2-year mark
- No Wi-Fi out of the box — requires Winix Smart app setup
- Filter replacement is annual but costs ~$60–$80 CAD
What Real Users Say
Sourced from Reddit, Amazon.ca, and independent review sites.
4.0Verified Buyervia Reddit r/AirPurifiers2025"It's pretty quiet on all but turbo. Turbo sounds like a jet engine — but I only use that setting for 20 minutes when smoke is bad, then drop it to auto. Customer support with Winix was relatively painless when I had an issue."
4.0Two C610 Ownervia Reddit r/AirPurifiers2025"Pretty quiet on low. I just started using two C610s and a 909 this week — happy with the noise level. The auto mode actually works, unlike some purifiers I've had."
5.0Ontario Homeownervia Amazon.ca Review2025"Bought this at Costco for wildfire season 2025. Covers my entire open-concept main floor. The 360° design means I can put it anywhere and it works. Annual filter (one swap per year) is much easier than the quarterly carbon on the C545."
5.0breathequality.comvia Independent Lab Test2026"In controlled testing, the C610 removed 99.9902% of particles in a 200 sq ft room over one hour — ranking 4th out of all Winix models tested. Energy Star certified, 22 dB minimum noise. A strong performer at this price."
Who Should Buy It?
Anyone with an open-concept main floor over 400 sq ft. Anyone who wants near-silent overnight operation (22 dB sleep mode is exceptional). Anyone fed up with quarterly filter changes — the C610's annual filter schedule is much easier to manage. Pairs well with a C545 in the bedroom: C610 in the living area, C545 in the bedroom.
Costco Canada Note
Costco Canada carries the C610 with an additional filter set included (item #3449587). Watch for sale pricing — it regularly drops from $189.99 to $139.99–$159.99 during member-only sales.
Final Verdict
The C610 is the better long-term buy for most Canadian homes if you can spend $30–$50 more than the C545. The quieter sleep mode, 360° placement flexibility, and annual filter schedule are meaningful quality-of-life upgrades. Grab it at Costco Canada when it's on sale — the $159.99 Costco price is exceptional for this spec level.
