The PuroAir 240 is the high-volume best-seller of the affordable air-purifier world: HEPA-14 plus activated carbon, a rating up to 1,000 sq ft, an auto air-quality sensor, and a price that undercuts the premium names. It is the no-fuss bedroom-and-office pick.
PuroAir built a hit. The 240 is a perennial Amazon best-seller and a Newsweek Readers Choice winner, and the reason is simple: it is rated for a large room, runs a true HEPA-14 filter with an activated-carbon layer for odors and VOCs, auto-adjusts to an air-quality sensor, stays quiet, and costs a fraction of a Coway or Blueair. For a bedroom, a home office, or a renter who wants cleaner air without overthinking it, that is real value at around $199.99 (and it is frequently on sale below $160).
The honest caveat, because this is a review and not an ad: independent testing houses are mixed on the 240's clean-air delivery relative to its marketing. Outlets like HouseFresh have argued its real-world particulate clearance trails the genuine performance leaders (Coway Airmega, Blueair, IQAir) once you account for room size and run time. So treat the 1,000 sq ft rating as a best-case number, size up rather than down, and run it on a higher fan setting in a large space.
Where it lands: the PuroAir 240 is the value play, not the performance crown. For a bedroom or medium room where you want solid HEPA filtration, quiet operation, and a friendly price, it is an easy recommendation. If you are chasing independently-measured top-tier clean-air delivery or whole-home purification, step up to a Coway Airmega, a Blueair, or - at the premium end - IQAir.
Renters and households who want quiet, affordable true-HEPA filtration for a bedroom or medium room, and value simplicity and price over chasing the highest measured clean-air delivery rate.
You want independently-verified top-tier clean-air delivery or whole-home coverage. Then a Coway Airmega, Blueair, or IQAir is the better, pricier buy. And size up: do not trust the 1,000 sq ft figure for a truly large open space.

PuroAir PuroAir 240 - buyer FAQ
Does the PuroAir 240 really cover 1,000 sq ft?
That is the best-case figure. Independent reviewers note real-world clean-air delivery on a large open space trails the marketing number, so the practical sweet spot is a bedroom or medium room. If your space is near 1,000 sq ft, run it on a higher fan setting and consider two units or a higher clean-air-delivery purifier.
What does it filter, and what do replacement filters cost?
A true HEPA-14 filter captures fine particulates (dust, pollen, pet dander, smoke), and an activated-carbon layer handles odors and VOCs. Replacement filters run about $40 every 6 to 8 months depending on use, which is the real ongoing cost to budget for.
PuroAir 240 vs Coway, Blueair, or IQAir?
PuroAir is the value pick: solid HEPA filtration at a much lower price. Coway Airmega and Blueair win on independently-measured clean-air delivery, and IQAir is the medical-grade whole-home option. Buy PuroAir for a bedroom on a budget; step up to those if you want verified top-tier performance or whole-home coverage.
How much does it cost?
List is about $199.99, and it is frequently discounted lower, often to roughly $159. That price, plus the large coverage rating and quiet auto mode, is why it is a consistent best-seller even though it is not the measured performance leader.
