Summary

A compact HEPA + carbon air purifier for small rooms, quiet enough for a bedroom but too weak for the 1,000 sq ft it advertises. Check the room size before you buy: independent testing supports about 284 sq ft at 4.8 air changes per hour.

Strengths

  • Energy Star certified with a 2-year warranty.
  • Quiet at low speed — 36.9 dB at Speed 1, suitable for bedrooms.
  • Filter-life indicator and air quality sensor add convenience.
  • Compact footprint for small rooms under 300 sq ft.
  • Some owners report noticeable allergen and dust reduction.

Weaknesses

  • Measured CADR of 181–204 CFM supports only ~284 sq ft, a quarter of the advertised 1,000–1,115 sq ft.
  • Low-speed dust, pollen, and smoke removal rated poorly by Consumer Reports.
  • Build quality described as “poor” by HouseFresh — a close copy of the Levoit Core 300 with cheaper materials.
  • The HEPA H14 grade’s claimed 10× improvement over H13 has no published lab evidence.
  • Annual filter cost of $108–$192 matches or exceeds the $47 electricity cost.
  • PuroAir sued HouseFresh over its critical review, raising transparency concerns.

Room coverage and CADR

The 1,000–1,115 sq ft figure on the box is a marketing number based on one air change per hour. At the EPA-recommended 4.8 ACH, HouseFresh calculated the unit covers roughly 284 sq ft. Its measured CADR — dust 183 CFM, smoke 181 CFM, pollen 204 CFM — puts it well behind similarly priced competitors. RTINGS describes a “low-powered motor” that limits airflow. Consumer Reports places it 4th of 35 in the extra-large room category but rates its low-speed particle removal poorly. Wirecutter included PuroAir models in its “Competition” section, not among its recommendations.

For rooms over 300 sq ft, look for units with CADR of 300 CFM or more. The PuroAir 240’s cost per CADR CFM is $1.15, among the highest in its class, compared to $0.68 for the Levoit Core 300.

Noise and power

HouseFresh measured 36.9 dB at Speed 1, 42.2 dB at Speed 2, and 52.2 dB at Speed 3 from 3 feet. The manufacturer claims 24 dB at its lowest setting, but no independent test has confirmed that figure under real-world conditions. Power draw ranges from 11.6W in sleep mode to 36.2W at top speed.

Filters and running costs

The filter sticker claims 12-month life, but the manufacturer recommends replacement every ~90 days. Replacement filters cost $48 each (HouseFresh), or $54 — $39 with a subscription (MindBodyGreen). Consumer Reports estimates $108 a year for filters plus $47 for electricity, totaling about $155 annually. HouseFresh’s own estimate ranges from $135.53 to $231.99 depending on calculation method.

Over three years, filter costs alone can approach or exceed the purchase price. PuroAir sells replacement filters directly; no broader repair parts are available.

Is it worth it?

At $80 or less, the PuroAir 240 could serve a small bedroom adequately. At its normal $160–180 street price, it competes against units with two to three times the CADR. Consumer Reports listed it at $159.99 in June 2024. PuroAir’s own site sells it at $179.99, marked down from $199.99 (PuroAir, 2026-10). MindBodyGreen listed it at $159 in July 2024. HouseFresh referenced $159 at the time of their 2024 review.

The annual filter cost makes long-term ownership more expensive than the sticker price suggests. For a small room at a deep discount, it is a reasonable budget option. For anything larger, the measured airflow does not justify the price.

Which model this is

This page covers the PuroAir 240 HEPA Air Purifier, ASIN B0998FWTHP. PuroAir also sells the Lite, 100i, 130i, and 400 — different units that should not be confused with the 240. The “HEPA 14” branding refers to the filter grade, not a model revision.
