Model-identity warning (read first)
Evidence for "HPA600B" is inconsistent and the model number appears to cover two different products:
- US Honeywell Professional Series HPA600B — the subject of this dossier: $699-class tower, CADR ~210 smoke, 325 sq ft, 44 W, 5-year warranty, Bluetooth smart features.
- India "Honeywell Air Touch HPA600B" — a distinct India-market luxury model (₹212,323 on gadgets360.com, Sep 2026) sharing the model number. Do not mix its pricing or positioning into US buying decisions.
The seed/marketing claim of "2,310 sq ft" coverage was not independently confirmed and contradicts the 325 sq ft figure in multiple sources — treat as UNVERIFIED marketing.
Specifications (US Professional Series)

|---|---|---|
| CADR | Smoke 210 CFM / dust 184 CFM / pollen 205 CFM | breathequality.com; hvaclifehack.com |

Pricing & total cost of ownership (dated 2026-09-23)
| Item | Figure | Dated source |
|---|---|---|
| Unit price | $699 MSRP; "as low as $599" observed | hvaclifehack.com (Fall 2025 review); breathequality.com |
| Replacement filter (HRF-Z2) | $139, ~1-year life | Prior research |
| Annual filter cost | ~$139/yr | Derived |
| 4-year TCO (filters only) | $1,255 at $699 ($699 + 4×$139); $1,155 at $599 | Derived |
Note: Target's price archive shows $599.99 in 2021–22 — the model has been in market for years; "new 2026 model" framing from some affiliates is misleading.
Attributed complaints & failure modes
- High price for modest CADR: the consistent critique — ~210 smoke CADR at $699 compares poorly with Coway/Winix/Levoit alternatives (hvaclifehack.com pros/cons table; breathequality.com).
- Affiliate-review superlatives ("best in world" style language) are unsupported editorial opinion, not evidence (breathequality.com).
Specialty-use notes (attributed, not our verdict)
- Honeywell's professional-series positioning targets buyers who trust the brand's HVAC heritage — brand positioning, not a performance claim.
- No wildfire/allergy efficacy trial found in the documented sample.
Community / social pulse
- UNVALIDATED on the social layer — Threads/Facebook discovery held for security review 2026-09-23; results pending (access limitation, not no-results).
Evidence gaps
- Noise levels: UNVERIFIED. Current US street price (2026): thin — $699 MSRP and $599 low are the dated figures available; verify at checkout. Model-number collision with the India Air Touch line needs a definitive manufacturer statement.
