Tech review: Dyson is a champ at purifiying the air and keeping you comfortable

You can also completely control the unit from the Dyson app on your phone or tablet. You connect the HP09 to your home’s Wi-Fi network, so you can use the app to control it from anywhere, even when you are away from home.

It is compatible with voice control from Amazon’s Alexa, Apple’s Siri and Google Home, so you can make adjustments with just your voice.


The Dyson HP09 is a little on the expensive side, but people with serious allergies or sensitivity to pollutants and chemicals will find it does a terrific job at keeping the air clean. Just knowing your room’s air quality is a huge step in keeping the air clean.

It is a room-sized fan. It is not a whole-home solution. It can heat or cool relatively large rooms, but it works best if it can concentrate on one area. I found it perfect for our bedroom.


We like to burn incense occasionally, and when we do, the HP09 has no problem detecting the increased smoke in the air and jumping into action.

The app control and voice control are both super convenient, and I love the fact that the formaldehyde filter never needs changing.

There is an ongoing cost of changing the HEPA filter once or twice a year, but that’s not too much to pay for better air.
