Blueair Protect 7470i is a tall white air purifier built for rooms up to 418 square feet. Its narrow 27.2-inch profile places the controls, sensors, and filter system in a single tower.
Large Room Air Cleaning
The unit measures 27.2 x 11.8 x 11.8 inches and weighs 27.6 pounds. Blueair lists an energy range of 8-48 W, with a low setting rated at 22 dB and a high setting rated at 45 dB.
The model's clean air delivery rate reaches 280 cfm for pollen, 275 cfm for dust, and 270 cfm for smoke. Blueair specifies 4.8 air changes per hour for the recommended 418-square-foot room.
Smart Controls And Filtration
HEPASilent Ultra combines mechanical and electrostatic filtration in the HealthProtect platform. Integrated sensors monitor indoor air conditions, while Wi-Fi connectivity enables remote control through the Blueair app.
The device uses one filter and supports automatic operation alongside three fan speeds. Blueair's specification page also lists cleaning capacity for larger spaces, including 1,000 square feet in 30 minutes and 2,000 square feet in one hour.
Price And Product Position
The Protect 7470i carried a comparable value of $759.99 before a clearance listing priced it at $159.99 as of 09/02/2026. Best Buy identifies the item as a discontinued model, placing that figure in clearance rather than regular pricing.
Tom's Guide recorded a $759 price during its review and measured the purifier at 27.2 x 11.8 x 11.8 inches, with a 27.6-pound weight. Compared with smaller air purifiers, the 7470i offers substantially higher stated room coverage but occupies more vertical space.
Who The 7470i Fits
The Protect 7470i suits users who need a smart air purifier for a large bedroom, living area, or open room and want quantified CADR ratings for pollen, dust, and smoke. Its 418-square-foot recommendation and Wi-Fi control give it a clear large-room role.
Its height, 27.6-pound weight, single-filter design, and discontinued status limit its appeal for compact rooms or shoppers seeking the newest Blueair platform. The clearance price improves its value when the exact model is available, while ongoing filter costs remain part of ownership.
