Dyson Purifier Big+Quiet Formaldehyde review: big, quiet, powerful and pricey

Dyson Purifier Big+Quiet Formaldehyde: Two-minute review

January 2024: The Dyson Purifier Big+Quiet Formaldehyde was initially only available in the US and Australia, but one model is now available in the UK as well. We’ve updated the price section of this review to reflect that.

It was not love at first sight with the Dyson Purifier Big+Quiet Formaldehyde, but after just one day of using it in my own home, I don’t want to ever be parted from it – strong words for a rather big and bulky purifier fan, but I stand by it. It’s completely different from any of Dyson’s previous home purifiers – in terms of both design and functionality – although it shouldn’t be confused with the HEPA Big+Quiet that’s specifically for commercial spaces.

Like its name suggests, it is big and it is quiet. It’s been made to circulate clean air in large rooms while standing in a corner instead of in the center of a space to be at its most effective. Dyson says it can service spaces that are up to about 100sqm / 1,000sqft in size, projecting filtered air up to 10m. Moreover, the angle of the propelled air can be adjusted (there are three to choose from), so it doubles up as a powerful fan as well which, at full bore, isn’t louder than 56dB.
