A Blueair air purifier with WiFi lets you check air quality, change fan speed and set schedules from your phone, and the Signature SP4i, Signature SP1i, DustMagnet 5440i and Classic Pro CP7i all offer some form of app control. The best choice comes down to room size: the SP4i covers the biggest spaces, the CP7i gives the most detailed air data, the DustMagnet targets dust before it lands on your gear, and the SP1i is the compact smart pick for bedrooms.
This guide ranks five Blueair models for gaming rooms, where dust settles on keyboards and gets pulled into PC intakes. Four of them are app-connected; the fifth, the Blue 511, is included because it is Blueair’s most compact purifier, but its listing does not mention WiFi or app control, and we say so plainly. We compared listings and specifications rather than running our own air tests, and ranked the models by app control, coverage and quiet running.

The BLUEAIR Air Purifiers for Home Large room model, the Signature SP4i, has the biggest reach in this list. Blueair says it cleans 705 square feet in 12.5 minutes and up to 3,385 square feet every hour. Filtration is a 7-stage HEPASilent system that captures 99.97% of airborne particles down to 0.1 microns, plus OdorFence technology aimed at odors, gases and VOCs.
App control is the most complete here: fan speed, schedules and settings from anywhere, with Auto Mode adjusting to indoor air conditions. The controller field lists Amazon Alexa, Android and iOS. An air quality indicator built into the outlet shows five colors from blue for excellent to red for poor. The furniture-style design doubles as a side table, and pre-filters come in interchangeable colors.
The noise figures need a note. The features say it runs as low as 23 dB, while the specification field lists 62 dB, which is most likely the top fan speed. Expect whisper-quiet on low and noticeable airflow on high. It suits a large lounge or basement setup; for a single bedroom, the SP1i is the better size.
- 705 sq ft in 12.5 minutes, 3,385 sq ft per hour
- 7-stage HEPASilent with OdorFence
- App schedules and Auto Mode
- 5-color air quality light in the outlet

The BLUEAIR Air Purifiers for Home Bedroom model, the Signature SP1i, is the small smart member of the Signature line. Blueair describes it as one of the smallest smart air purifiers available, and it measures 9.37 by 9.37 by 13.82 inches at 5.64 pounds. It cleans 248 square feet in 12.5 minutes and up to 1,190 square feet every hour.
It uses the same HEPASilent approach, capturing 99.97% of particles down to 0.1 microns, including dust, smoke, pollen, pet dander and mold spores. The listing calls it a smart purifier, but the description is cut off before it details the app, so it does not specify which app features or voice assistants it supports. Check that before buying if a specific assistant matters to you.
This is the pick for a bedroom that doubles as a streaming room or a dorm desk. Our guide to the Blueair air purifier for a small room goes deeper on sizing. For more space, step up to the DustMagnet or SP4i.

The BLUEAIR Air Purifiers for Home DustMagnet 5440i is built specifically for dust. Dual air intakes and vortex airflow keep particles moving, electrostatic charges clump them together, and charged stainless steel pre-filters hold on to them. Blueair claims it captures 99% of dust before it settles, which is exactly the problem in a room where fans stir everything up.
It lists AHAM-verified CADR of 216 for smoke, 274 for pollen and 231 for dust. The listing is inconsistent on coverage: the title says up to 1608 square feet, while the feature text says 357 square feet in about 12.5 minutes or 1,713 square feet in 60 minutes on high. It runs at 30 dB on low, uses 7 W on low, and is Quiet Mark approved and ENERGY STAR rated. The app offers real-time tracking, and the listing names Amazon Alexa.
Night Mode lowers fan speed and dims the LEDs, and a Welcome Home feature is described as saving energy while keeping air clean for your return. The carbon filter handles light household odors, so a smoky room is better served by the SP4i’s OdorFence. The tabletop top is a nice touch next to a desk.

Blueair Classic Pro CP7i

Affiliate link. Price and stock live at Amazon and change there, not on this page.
The BLUEAIR Air Purifiers for Home Large room Classic Pro CP7i uses a dual-fan, dual-filter layout that pulls air in and pushes it out through two side outlets. Blueair quotes 589 square feet in 12.5 minutes and 1,413 square feet in 30 minutes on high, with the title giving up to 2,923 square feet. The specification field lists a floor area of 650 square feet, which does not match the title, so go by the timed figures.
It has the most informative display: a 5-color AQI plus a numeric pollution reading, with eco and auto modes. The app handles remote control, schedules, usage notifications, indoor and outdoor air quality, and filter tracking with easy reordering. HEPASilent dual filtration captures 99.97% down to 0.1 microns, and a light-based feature the listing calls HINS Pure (the description names it PhotonPure) flashes blue light every 10 minutes. It is CARB certified and listed as zero ozone by Intertek.
The steel housing and up to a 5-year warranty suit someone who wants a long-term unit. The listed 59 dB noise level is louder than the SP4i’s low setting, so place it away from your mic.

The BLUEAIR Air Purifiers for Home Bedroom Blue 511 is Blueair’s most compact purifier at 7.9 by 7.9 by 13.9 inches and 5.24 pounds. It cleans 180 square feet in about 12.5 minutes or 432 square feet in 30 minutes on its highest speed, and the title quotes up to 907 square feet.
Blueair sells it on plug-and-play simplicity and low noise for bedrooms and offices. The listing does not mention WiFi, an app or voice control, so it does not belong in a smart-home setup. We include it for readers who want the Blueair filter approach in the smallest package and are happy to use the button on top.

NOTES
Buying Tips for Blueair WiFi Air Purifiers
Size by the 12.5-minute figure, not the hourly one. Cleaning a room in about 12.5 minutes works out to roughly five air changes per hour, which is what allergy-focused guidance generally aims for. The hourly numbers look impressive but describe just one air change.
Factor in filters. Every model here depends on replacement filters to keep performing, and the CP7i’s app tracking makes that easiest. Our Blueair filters guide covers replacements.
Finally, place the purifier where it does not fight your PC. Keep it a little way from walls and out of the direct path of case exhaust, and run Night Mode or a schedule during streams so fan noise stays off the mic. If you are still deciding on the brand, our Blue Air purifier overview is a good starting point.
