Product Information

Other filtration technologies are harder to evaluate, including those that incorporate activated carbon and ultraviolet light.

The problem is particularly acute in our cities: poor air quality outside can cause poor air quality indoors. Naturally grown reindeer lichen helps to trap and remove particles like pollen and other allergens, while a dense layer of coconut coir targets mould and bacteria. While an air purifier's ability to remove contaminants is the most important criterion, our experts also consider such factors as ease of use, maintenance and operating costs, the same way we do with other air treatment equipment, like humidifiers, portable air conditioners, dehumidifiers and dehumidifiers for your basement.

Another possible concern is regarding air purifiers that use ionizers to help attract particles like static. Most impressively, Philips says the filter only needs changing once every three years – a huge improvement on comparable machines – which would represent a sizeable saving in the long term.

It rivals our top-ranking BlueAir for performance, though it fell short of the winner's circle due to its less-than-average coverage area (361 square feet versus the 540 square feet of the Blue Pure). Based on an extensive preliminary review of technical data, including claimed coverage area and type of filtration, our review team selected various 2023 models for hands-on testing, which took place both in our Lab and homes, the latter allowing us to test how they performed in real-world conditions. It’s also worth comparing manufacturer figures for the maximum size of room as these can vary enormously, sometimes when the CADR doesn’t.

Indeed, we’ve found low-cost machines with features that are usually only found in much more expensive models. The Sleep Mode (with an optional night light), allows your or your kids to drift off while it quietly goes about its business.

Here, you can switch between the three fan speed settings or set the off timer, with two-, four-, six- and 12-hour settings. Our consumer testers measure factors like ease of setup, intuitiveness of controls and how uncomplicated it is to locate and replace the filter (or clean it, when applicable).A handy sleep mode means the purifier can continue to operate quietly without disturbing anyone, and there’s an optional night light if preferred, so it’s a good choice for smaller bedrooms once the workday is over. While many of us worry about the air quality on bustling city streets – heck, Dyson even launched a wearable air purifier to tackle the problem – few of us are aware that the air we breathe inside our homes can be just as detrimental to our health. It claims to remove up to 99 per cent of pollen, pet dander, dust and mould spores, and we definitely felt the air was a little clearer in the bedroom we used it in. I was shocked at just how quickly it could heat the room and it now gives me peace of mind that a quick burst of heat can bring my office up to temperature within minutes rather than hours.

But Dyson has proven itself splurge-worthy in other product categories, from cordless vacuums to hair dryers, and that’s what our experts found with its latest air purifier, the Dyson Humidify+Cool Formaldehyde. Even 2023 air purifiers that excel at removing particles like dust, smoke and pollen are limited in their ability to capture smaller toxins, such as those from cleaning products and paint.While it can in theory clean larger rooms up to 36m2, it’s definitely more effective in smaller areas.
