Decision answer
Bottom line
PuroAir describes the 240 as a 45 W purifier for spaces up to 1,000 sq ft, with a 24 dB lowest setting, an air-quality sensor, auto mode, and a three-layer pre-screen, HEPA, and activated-carbon filter. The room-size statement is not a pollutant-specific CADR, so compare products on equivalent test bases and include replacement filters in the ownership cost.

Research details
Bottom line
PuroAir describes the 240 as a 45 W purifier for spaces up to 1,000 sq ft, with a 24 dB lowest setting, an air-quality sensor, auto mode, and a three-layer pre-screen, HEPA, and activated-carbon filter. The room-size statement is not a pollutant-specific CADR, so compare products on equivalent test bases and include replacement filters in the ownership cost.
Published specification basis
PuroAir publishes the 240's dimensions, 45 W draw, 24 dB minimum setting, sensor controls, and three-layer filter description. Its up-to-1,000-sq-ft statement is not accompanied by pollutant-specific CADR on the cited pages, so it cannot be compared directly with an AHAM room rating.
Ownership cost and purchase terms
Model the PuroAir 240 with the cost and cadence of genuine replacement filters, not only the unit price. The advertised lifetime warranty is conditional on an active filter subscription, making subscription terms part of the ownership calculation.
Before you follow the offer
The approved listing should show PuroAir 240 and ASIN B0998FWTHP. Check the seller, filter supplied with the unit, current subscription choices, delivery total, voltage, return policy, and whether the warranty terms shown at checkout match PuroAir's current policy.
Evidence boundary
BenchPicked has not independently verified filtration efficiency, room clearing time, or the 24 dB claim. This page therefore distinguishes PuroAir's published coverage language from a measured CADR-based result.

What should I verify before following the offer?
Confirm that the Amazon page still identifies PuroAir 240 HEPA and ASIN B0998FWTHP, then verify seller, included parts, delivered price, regional compatibility, return terms, and warranty.
