Winix AM90 Review (Canada, 2026) — Best for smart-home setups — Alexa, Google Home, app.
By Winix Canada · Updated June 2026 · Independently tested
Overview
The Winix AM90 occupies an interesting niche: it has the same proven HEPA + carbon filtration as the 5500-2 (on which it's based), but it's designed first and foremost as a smart-home hub. Native Alexa and Google Home support — not via a skill, but a direct integration — makes it the best Winix for automating air quality around your schedule. Running it at max speed before you wake up, triggered by your sunrise alarm routine? The AM90 does that out of the box. Home Assistant users have built full PM2.5 automations around it. If your home is already on a smart platform and you want your air purifier to participate, the AM90 is the obvious Winix pick.

Performance
The AM90 posts essentially identical CADR numbers to the 5500-2 it replaced (243 CFM smoke) and performs consistently in independent testing — clearing a 360 sq ft room of PM2.5 in approximately 18 minutes at max speed. Where it differentiates is responsiveness: with auto mode active, the particle sensor ramps from sleep to Speed 3 within 90 seconds of detecting smoke — faster than the C545's slower sensor response. Home Assistant users report reliable PM2.5 readings via the cloud integration with ~2-minute polling intervals.
Noise Levels
Measured at 3 ft. from the unit.
| Speed | dB Level | What it sounds like |
|---|---|---|
| Sleep Mode | 27 dB | Near-silent — ideal for bedrooms |
| Speed 1 | 32 dB | Very quiet |
| Speed 2 | 40 dB | Soft background noise |
| Speed 3 | 47 dB | Comfortable white noise level |
| Speed 4 (Max) | 55 dB | Audible but quieter than C545 max |
Filter Costs in Canada
The AM90 uses Winix Filter A (115115 — same as the 5500-2 and A231) for HEPA (12 months) and a carbon filter (3 months). OEM Filter A on Amazon.ca: ~$45–$65 CAD. Carbon filter: ~$15–$25 CAD × 4 = ~$60–$100/yr. Combined annual cost: ~$100–$140 CAD. Third-party Filter A alternatives (widely available) cut this to ~$70–$90/yr.
Pros & Cons
Pros
- Native Alexa and Google Home — no skill required
- Home Assistant compatible (via Winix Smart app cloud)
- Same strong 5500-2 filtration platform — proven HEPA
- Quieter max speed than 5510 at 55 dB vs 59 dB
- Air quality visible in the Alexa app and Google Home
- Scheduling via voice: 'Alexa, turn on the air purifier at 6am'
Cons
- Larger, heavier footprint than C545/C610
- No pelleted carbon (uses impregnated, like C545 — slightly less VOC control than 5510)
- Not at Costco Canada
- Some users report intermittent app disconnection after firmware updates
What Real Users Say
Sourced from Reddit, Amazon.ca, and independent review sites.
5.0Smart home uservia Reddit r/homeassistant2025"The AM90 integrates perfectly with Home Assistant via the Winix Smart app. I have it on an automation — runs at speed 3 whenever outdoor AQI goes above 50. Set it and forget it."
5.0howtotechinfo.comvia Independent Review2025"The AM90 is the smart-home version of the 5500-2 — same excellent filtration, same proven AOC carbon filter, but with WiFi, Alexa, and Google Home baked in. It's a meaningful upgrade for tech-savvy households."
4.0Toronto apartment ownervia Amazon.ca Review2026"Works great in my 350 sq ft condo. The app is genuinely useful — I can see real-time air quality, set schedules, and check filter life remaining. Much better value than a Dyson at this price."
Who Should Buy It?
Smart-home enthusiasts who want native Alexa or Google Home air purifier control. Home Assistant users who want a PM2.5 sensor and automated purifier in one device. Anyone upgrading from a 5500-2 who wants to add voice control. Not the right buy if you don't use a smart-home platform — the C545 gives you the same filtration for $100 less.
Costco Canada Note
The AM90 is available at Home Depot Canada and Amazon.ca. Not carried at Costco Canada. Home Depot sometimes offers it with a free extra filter at spring air quality sales.
Final Verdict
For smart-home setups, the AM90 is the best Winix you can buy in Canada. Native integration means it works with voice assistants and Home Assistant without jailbreaking anything. The filtration is proven and reliable. The only knock is that it uses the impregnated carbon filter (like the C545) rather than the pelleted version in the 5510 — slight disadvantage for serious odour control. But if smart integration is your priority, the AM90 delivers.
