PuroAir 240 HEPA Air Purifier Review: Would Owners Buy It Again?
Disclosure: As an Amazon Associate I earn from qualifying purchases. If you buy through links on this page we may earn a commission at no extra cost to you. How this review was made: We did not test this purifier ourselves. This verdict rests mainly on one detailed independent test, by HouseFresh, which includes room-size and airflow figures from an AHAM-verified report. We found few other rigorous tests of this exact model, and say so below. Our method.
Skip it: the room-size claim is far above what the test data supports
HouseFresh, which tests air purifiers with its own particle sensors, says the PuroAir 240 cleaned a test room more slowly than a model that costs about half as much, and does not recommend it. The airflow figure in the AHAM-verified report supports coverage of roughly 284 sq ft, while the listing advertises about 1,000 sq ft. It is quiet at low speeds and looks neat, but better-tested, cheaper alternatives exist.
Check current price on Amazon → Prices and availability change often, so we don't list them here.Buy it again if you…
- want a quiet unit and are fine with a small room
- already own it and only need to know filter costs
Skip it if you…
- bought it expecting to clean a large open-plan space
- want the best air cleaning for the money
- want low yearly filter costs
The PuroAir 240 is a compact tower-style HEPA air purifier sold directly and on Amazon. Its marketing says it covers about 1,000 sq ft and uses a HEPA 14 filter.
This page summarises independent testing, mainly HouseFresh's review, and explains why we land on skip. It is a consumer-product opinion, not a health claim. Air purifiers reduce airborne particles but are not a treatment for any condition, so check with a doctor if you have health concerns.
What owners say, at a glance
Bars show our editorial summary of how consistently owners praise or complain about each area across all sources — not a lab measurement.
What the independent test found
HouseFresh (review by Danny Ashton, updated September 2026) ran the PuroAir 240 in a 728 cu ft room with particle sensors. It took 48 to 51 minutes to bring fine-particle readings to zero. The Winix A230, which the reviewer notes costs about half as much, did it in 40 minutes. HouseFresh's conclusion is that the unit "has poor air cleaning performance for its price, and is not a device we recommend."
Claims versus tested figures
| Coverage | Marketing says about 1,115 sq ft. The AHAM report, as cited by HouseFresh, supports about 284 sq ft at 4.8 air changes per hour. At the advertised size, HouseFresh calculates roughly one air change per hour. |
|---|---|
| Airflow (CADR) | 181 to 183 CFM for dust in the AHAM report cited by HouseFresh. |
| "10x better than H13" | HouseFresh's own H13 filter test cleaned the room about three minutes faster than the H14 filter. |
| H14 lab testing | The reviewer said he could not verify the lab testing and university involvement mentioned in marketing. |
HouseFresh goes further and says the company is "knowingly overstating" the capability. That is the reviewer's opinion, and we report it as such. We did not find a regulator ruling against the 240. A separate industry self-regulation decision about the larger PuroAir 400 found certain HEPA claims supported, so this is not a blanket finding about the brand.
What it does well
What counts against it
Evidence gaps
Most of what we cite traces to one outlet. RTINGS has a page for the 240, but the full results were not readable to us, so we do not rely on it. Owner reviews on retail sites praise the quiet running and ease of use, but we do not treat those as test data.
If you already own one
- Use it in a bedroom or small office, where the tested airflow is enough.
- Run it on a higher speed for faster clean-up, accepting more noise.
- Do not rely on it for a large open space.
Pros and cons
What owners love
- Quiet on low and middle speeds
- Neat, compact design
- Rubber feet keep the bottom cover secure
- Fine for a small room
What owners complain about
- Cleared a test room more slowly than a cheaper rival
- Advertised room size far above the AHAM-supported figure
- Weak value per unit of airflow
- Filter replacements add to running cost
