Dyson
Dyson is updating its range of air purifiers with two new models, including one that eliminates formaldehyde.
The two models are the Purifier Cool and the Purifier Cool Formaldehyde. I think the name tells you much of what s different about the two but it s important to talk about the improvements.
General improvements
The design is largely unchanged, which isn t a bad thing at all given how distinctive they look. You can tell the two apart from the accents – the Purifier Cool Formaldehyde is the only model with gold accents.
One big improvement to these two air purifiers is that the entire machine now meets HEPA H13 standard . In other words, it s fully sealed. What is captured inside can t escape.
Dyson claims that the new Hot+Cool range can filter out up to 99.95% of all airborne pollutants in a room up to 81m³, using no fewer than nine individual sensors to measure air purity. Formaldehyde is one such pollutant: 500 times smaller than 0.1 microns, formaldehyde particles are clearly the white whale of air purification. Dyson has created a solid-state sensor – as opposed to the gel-based sensors of old – that deals with those microscopic pollutants by destroying them at a molecular level.
Each Hot+Cool air purifier is also HEPA H13 certified. This applies to the entire machine, rather than just the filtration system itself, meaning in simple terms that impure air has no possible point of exit once it enters the purifier.
