5 of the Best Air Filters
Take a breath with devices that scrub pollen, pollution and other unwanted particles from your home
Dyson Purifier Cool Autoreact
Dyson claims its sleek and recently updated Purifier Cool will capture 99.95 per cent of pollutants, gases, odours, pollen and dust mites, including ultrafine particles just 0.1 microns across – that includes viruses like H1N1. An activated carbon filter also nabs gases like NO2.
As a company, Dyson puts its efforts into the quality of the filters and says less about the clean air delivery rate, claiming the rating isn’t representative of a standard room in an average home. Even so, it says the Purifier Cool was tested in a chamber 81m3 (2,860ft3 ) in volume – significantly bigger than some competitors.
Also impressive are the techy extras you get with a Dyson price tag. The filter has sensors to measure air quality – neatly displayed on a LED display – and gets to work when it detects something. There’s also an integrated fan (sans blades, as is the Dyson way) while other models have a humidifier.
