Pure Hot+Cool Formaldehyde HP09

Oh, fuck no. As an owner of four of these things, they’re some of my most regretted purchases. They have a laughably low CFM, are stupid loud on even medium speeds, develop squeaky bearings within months, the filters are expensive as shit, and the software sucks. Seriously, do not buy one of these. Edit: I have two TP07s, an HP04, and an HP09. They all suck equally.

We've got a Dyson HP09, I've integrated with Home Assistant, so it will turn on or off automatically if the air quality drops (while I'm cooking), then on and off during certain times when I turn the room's lights on or off. Haven't don't much more than that but it's a great bit of kit, and also looks good in the room

Dyson Pure Hot + Cool Link. I think it’s from 2016? The filters are a continuing cost but overall very happy with it.

If you looking for filter out dust you need the one has big and powerful fan but if you need one to filter out VOC and a microscopic stuff you better of looking for multi layer filter system with HEPA , I have used Coway for dust and Dyson formaldehyde for microscopic and IQAIR multigas for road traffic pollution next to my apartment!

There is truly no "one and done" air purifier for dust, as dust is too heavy to be pulled by typical air purifiers. The Dyson formaldehyde air purifier attempts to solve this issue, but directing air at stagnat pockets within a room to encourage dusty air to make it way towards the filter intake. That'll most likely be your best bet against dust if you don't want to manually remove it, ie vacuum, brush, etc etc.

i splurged and got the dyson air purifier that also works as a fan and space heater. personally, it was well worth the investment. i'm able to monitor the air quality, humidify and temperature in my home through an app.

It’s not necessary unless you have bad allergies or if there is smoke from some huge fire (knock on wood). I have Dyson combo fan/heaters with air purifier, so it’s automatically working when I use them.
