Is a Dyson purifier worth triple the price of a plain HEPA box? Purifiers

The two things worth paying for are a properly sealed filter path and enough carbon to matter, and the price tag does not reliably predict either. Compare the clean air delivery rate for smoke against your room volume, then check the annual filter cost. On a 30m2 open plan you want a unit that can turn the air over several times an hour at a speed you can live with, and the cheaper tower usually gets there by being louder, which is a real cost you will pay every evening.

Owned one of the expensive towers for two years, sold it. The formaldehyde and VOC readouts on the screen were the main reason I bought it and I stopped trusting them within a month, because the number would climb every time I opened a bottle of cleaning spray and then sit high for hours regardless of whether the unit was on. Air felt fine. So did the cheap box I replaced it with, at a third of the filter cost.

With a gas hob, the extractor is your air purifier. Ducted to outside if you have it, and run it for ten minutes after you finish cooking rather than switching it off when the pan comes off the heat. A recirculating hood with a tired charcoal cassette is doing almost nothing and no freestanding unit in the room will make up for it.

Going to gently push back on the pile-on. I bought the expensive one specifically because it has no exposed blades and a toddler who puts fingers in things, and the oscillation actually moves air across a long open-plan room in a way my previous squat box never did. I am not claiming it filters better per euro. I am saying the form factor was worth something to me and that is a legitimate reason to spend money.

Buy the EUR 190 one and put the EUR 460 you saved into filters and a second unit for the bedroom. Two average units in the two rooms you actually occupy beat one excellent unit in the room you walk through.
