This Dyson Air Purifier Is Now $200 Off
If you’ve ever wished your air purifier could do more than just purify, the Dyson Hot+Cool Formaldehyde HP09 makes some bold moves. It’s currently available for $649 (down from $849.99), which is still pricey, but not as painful as usual.
Yes, this machine is a purifier, but it’s also a fan and a heater, all in one unit. Designed for rooms up to 800 square feet, it uses a bladeless oval tower (classic Dyson) to project clean, warm, or cool air with a 350-degree oscillation range. That’s enough to cover most living rooms, and the unit is light enough (just over 12 pounds) to move from room to room without much hassle.
One of the most useful things about the HP09 is how much it tells you about the air you breathe. It doesn’t just claim to purify it — it shows you exactly what it’s removing. That includes everyday stuff floating around your home like dust, smoke, pollen, pet dander, fumes from cleaning products and sprays, off-gassing from furniture or paint, and emissions from gas stoves or candles. It tracks all of this in real time, breaking it down into easy-to-read stats on the purifier’s LED screen or in the MyDyson app (which also pulls in your outdoor AQI based on your location). You’ll see things like temperature, humidity, and overall air quality, as well as specific readings for fine particles (PM2.5), larger particles (PM10), volatile organic compounds (VOCs), nitrogen dioxide (NO2), and formaldehyde (this makes a big difference if you have new furniture or paint in your space).
The catalytic filter that breaks down formaldehyde never needs to be replaced, but the HEPA and carbon filters that trap other pollutants are estimated to last up to a year (replacements cost $79.99). You can control everything via an app or by voice using Alexa, Siri, or Google Assistant. However, it doesn’t have Apple HomeKit support, and you’ll still need the included remote to turn on the heat for safety. Plus, it gets loud when you crank it up to higher speeds, according to this PCMag review .
If you’re looking for a simpler, cheaper air purifier, the Dyson Purifier Cool TP07 for $449.77 (down from $649.99) lacks a heater and formaldehyde filter, but still keeps the air clean and your home plugged in.
