Winix 5500-2 Review
A perennial best-seller with AHAM-verified CADR 243 for smoke, True HEPA, and PlasmaWave technology — covers 360 sq ft at a hard-to-beat price.
Price: $139.99 · Last checked: 2026-04-01
Our Verdict
The Winix 5500-2 has held its position as a top-value pick for years for good reason: AHAM-certified CADR that competes with units $50–80 more expensive, a real air quality sensor that actually works, and a genuine auto mode. If you don't need smart app control, this is hard to beat at under $140.

Pros & Cons
✅ Pros
- AHAM-verified CADR 243 smoke — one of the highest in the $100–150 bracket
- PlasmaWave ionizer can be switched off — gives users control over technology they don't want
- Annual filter cost is effectively ~$50/yr with a single combined HEPA + carbon filter
- Auto mode with air quality sensor responds genuinely to pollutants — tested and verified by multiple independent reviewers
- Slimmer profile than most at this CADR — easier to place against a wall
❌ Cons
- No app or Wi-Fi control — fully manual operation only
- At 15.4 lbs it's one of the heavier units in this segment
- Filter replacement ($50) is higher than competitors that split HEPA and carbon separately
