Honeywell is one of the most recognized names in HVAC, and their air purifiers deliver solid, no-nonsense True HEPA filtration backed by AHAM-verified CADR ratings. The flagship HPA300 ($249, 300 CADR, 465 sq ft) has been a large-room workhorse for years and remains a reliable choice. However, Honeywell's lineup is showing its age in 2026 — no smart app connectivity, no air quality sensors, and higher filter costs than nimbler competitors like Levoit and Winix.
If you already trust the Honeywell brand from your thermostat, HVAC system, or other home products, their purifiers won't let you down on filtration. But if you're comparing features dollar-for-dollar, Levoit, Coway, and Winix all offer more value at similar or lower prices. Honeywell's strength is brand recognition and retail availability — you can find their purifiers at virtually every Home Depot, Lowe's, Walmart, and Target.
Honeywell Filtration Technology
All current Honeywell air purifiers use True HEPA filtration that captures 99.97% of particles at 0.3 microns. The filter system is straightforward: a carbon pre-filter for odors and large particles, followed by a cylindrical True HEPA filter for fine particulate removal.
Honeywell's HEPA filters use a pleated cylindrical design that maximizes surface area within a compact housing. The quality of the HEPA media is solid — these are genuine H13-grade filters with AHAM-verified performance. Where Honeywell falls behind is the activated carbon: their pre-filters use a thin carbon-impregnated mesh rather than granular carbon, providing minimal odor and VOC removal compared to brands like Alen or even Coway.
Honeywell's Legacy Advantage: Honeywell has been manufacturing air filtration products for HVAC systems for over 100 years. Their residential air purifier line benefits from this deep filtration expertise. The HEPA media and filter construction are among the most consistent in the industry, even if the smart features and design lag behind newer brands.
Complete 2026 Honeywell Air Purifier Lineup
No Smart Connectivity: None of Honeywell's current air purifiers have Wi-Fi, app control, or voice assistant integration. In 2026, this is a significant omission when competitors at every price point offer smart features. If remote monitoring, scheduling, or Alexa/Google control matter to you, look elsewhere.
Model Highlights
HPA300: The Large-Room Workhorse
The HPA300 is Honeywell's most powerful purifier at 300 CADR covering 465 sq ft. It uses three cylindrical HEPA filters arranged side-by-side for maximum surface area and airflow. This multi-filter design is one reason the HPA300 delivers strong CADR, but it also means replacement costs are higher — you need three HEPA filters plus a carbon pre-filter at each change.
At $249, the HPA300 competes directly with the Levoit Core 600S ($249, 410 CADR), and that comparison doesn't favor Honeywell. The Levoit offers 37% more CADR, a smart app, and lower filter costs. The HPA300's advantages are pure build quality, AHAM-verified reliability, and massive retail availability.
The HPA300 is also notoriously loud on high speed — 63 dB is louder than normal conversation and significantly noisier than the Levoit Core 600S (55 dB) or Coway Airmega 400 (52 dB) at max speed. On low speed (29 dB), it's reasonable for daytime use but not the quietest bedroom option.
InSight Series: Basic Air Quality Indication
The InSight models (HPA250B, HPA5300B, HPA5150B) add a colored LED air quality indicator that shows green, yellow, or red based on detected particle levels. This is the closest Honeywell gets to smart monitoring — there is no app, no PM2.5 reading, and no historical data. It is better than nothing but far behind what Levoit, Coway, or Blueair offer.
HPA020B: Budget Tabletop
At $89, the HPA020B is a compact tabletop purifier for small spaces (75 sq ft) like desks, nightstands, or small bathrooms. CADR of 60 CFM is very low — this is a supplemental device, not a room-scale purifier. It uses the same True HEPA technology but in a significantly smaller package.
Real-World Performance Testing
Example 1: HPA300 in a 450 sq ft Living Room
A homeowner in Philadelphia, PA ran the HPA300 in their 450 sq ft living room. Baseline PM2.5 was 16 µg/m³. On the highest of three speeds, PM2.5 dropped to 3 µg/m³ within 20 minutes — impressive for the rated coverage area.
However, at 63 dB on high, the unit was disruptively loud. The homeowner typically ran it on medium (approximately 48 dB) during the day and low (29 dB) at night. On medium speed, PM2.5 maintained at 5–8 µg/m³, and on low, it crept up to 8–12 µg/m³ overnight.
The three-filter design meant replacement costs were steep: approximately $70–$90 per year for three HEPA filters plus a carbon pre-filter. The homeowner later switched to a Levoit Core 600S and reported better air quality, lower noise, and lower filter costs.
Example 2: HPA250B InSight in a Bedroom
A user in Dallas, TX placed the HPA250B in their 280 sq ft bedroom. The colored air quality indicator was the primary "smart" feature, turning green after about 30 minutes of operation. PM2.5 (measured with a separate Temtop monitor) maintained at 3–5 µg/m³ on medium speed.
On low speed, noise at 29 dB was adequate for sleeping — not as quiet as a Blueair 411i+ (18 dB) or Levoit Core 300S (24 dB), but tolerable. The InSight indicator provided basic reassurance but the user wished for actual PM2.5 numbers and an app.
Example 3: Two HPA100 Units for a Townhouse
A couple in Columbus, OH purchased two HPA100 units ($298 total) for their 1,100 sq ft townhouse — one upstairs and one downstairs. Each unit covered approximately 155 sq ft effectively, keeping PM2.5 at 4–6 µg/m³ in the immediate areas.
The approach worked for the rooms where units were placed but provided minimal benefit to adjacent rooms. For whole-home coverage on the same budget, two Levoit Core 300S units ($198) or one Coway Airmega 400 ($350) would have been more effective.
Example 4: HPA300 During Wildfire Smoke
A homeowner in Sacramento, CA relied on the HPA300 during a five-day wildfire smoke event (outdoor AQI 180+). Running on high speed continuously, it maintained indoor PM2.5 at 10–18 µg/m³. The noise at 63 dB made it unbearable for extended use, so they alternated between high and medium speed.
The carbon pre-filter provided virtually no smoke odor removal due to its thin design. The homeowner supplemented with wet towels over the intake to capture some odor — a clear sign that the HPA300's carbon filtration is insufficient for smoke.

Who Should Buy Honeywell
Honeywell makes sense if you:
- Want a proven, reliable True HEPA purifier from a recognized brand
- Prefer buying from brick-and-mortar stores (widest retail availability of any brand)
- Don't need smart features, app connectivity, or detailed air quality data
- Already use Honeywell HVAC products and trust the brand
Skip Honeywell if you:
- Want smart app control, scheduling, or voice assistant integration
- Care about noise (Honeywell models are louder than most competitors)
- Want the best CADR-per-dollar value (Levoit and Winix beat Honeywell)
- Need effective odor or VOC removal (thin carbon pre-filters are insufficient)
Key Takeaways:
- Honeywell delivers reliable True HEPA filtration backed by AHAM verification and 100+ years of filtration expertise.
- The HPA300 ($249, 300 CADR) is a solid large-room purifier but is outperformed by the Levoit Core 600S ($249, 410 CADR) in CADR, noise, smart features, and filter costs.
- No smart connectivity across the entire lineup is a critical omission in 2026.
- Noise levels are higher than most competitors, especially the HPA300 at 63 dB max.
- Carbon pre-filters are too thin for meaningful odor or VOC removal.
- Honeywell's main advantage is massive retail availability and brand trust.
- 5-year costs range from $312 to $819 — slightly higher than Levoit and Winix for comparable performance.
