It’s speed makes it ideal for living rooms and bedrooms and it can be wall-hung to save space,” says Matt Thomas of John Lewis. This is because, rather than drawing in air from behind, it draws it from a ring around its front surface. There is also a ring of coloured light all round it, which changes from green to red according to the air quality levels. In smart mode it adjusts its power accordingly. The HoMedics stays quiet at its lowest two settings, but noise levels ramp up on its highest setting to around 54.1dB, making it louder than some larger models. It uses between 16W and 34W while in use. Performance is in line with other small purifiers, taking just over four minutes to bring our PM2.5 particulates down to safe levels from a high of 387 micrograms per square metre. However, with a HEPA filter, a carbon odour filter, an ioniser and UV-C treatment to combat germs, the HoMedics has a more robust set of air treatment features than other purifiers in its class. It’s affordable, but not at all basic. Some purifiers have a built-in timer. This can be really useful if you want your machine to come on a few hours before you get home, or if you want to turn it off automatically at night. At just 18dB on its lowest setting, the Blue 3210 is technically quieter than a whisper. It’s certainly the quietest we tested as well as one of the most efficient, using about as much energy as an LED lightbulb.
The first thing you notice is that the multi-award winning briiv is unlike anything else in the air purifier market. With it’s Scandi-looks and natural filters, it looks like miniature greenhouse. But it could just be the future of indoor air purification. In addition, many will include active carbon filters to remove traffic fumes, cigarette smoke and volatile organic compounds (VOCs) from people, animals, plants and products in our house. The carbon is treated to have an extremely high surface area – it’s ultra-porous – attracting small particles to it and trapping them. Active carbon filters are known for removing bad smells. Where to place an air purifier It’s as a purifier that we’re recommending it here. The Purifier Cool Autoreact offers an extremely high level of filtration, with a fully-sealed H13 HEPA system rated to remove 99.95 percent of particles down to 0.1 microns and a carbon filter to remove odours, harmful gases and VOCs (volatile organic compounds – see FAQ section below). The Wi-Fi setup is straightforward enough if you’ve ever done the same thing with other wireless-enabled appliances in your home. The unit has three different settings to choose from with an Auto option that essentially removes the need for any real setup as such. This sets the fan speed for you, based on the air quality the appliance has detected. So I guess the question is, is this air purifier worth it? I was extremely pleased with just how much it alleviated my allergies. I honestly wasn’t expecting the outcome to be so good. We’ve been using it for just over two weeks now and haven’t suffered from any allergy symptoms at all in that time. And I haven’t had to take antihistamines or my inhaler at all.The CADR aims to provide an objective measure of the effectiveness of a portable air purifier at dealing with different types of allergens. A purifier with a score of 250 for dust particles is as effective as adding 250 cubic feet of clean air per minute. Buyers should focus on the results of the specific pollutant they’re aiming to eradicate, whether that’s pollen, smoke or dust, and many manufacturers will supply CADR figures for the most common.
Smoke particles range in size from 0.1 to 1 micron in cigarettes, 10-100 microns in cooking smoke and 0.4-1 microns in exhaust smoke. Hoover home air purifiers capture particles as small as 0.3 microns, which means they can capture the vast majority of smoke particles – enough to feel, see and smell the difference. The H-Purifier 300, 500 and 700 all have pollen capturing and neutralizing built in as standard, as well as the pollen alerts. The difference between models is that the 500 comes with a diffuser which can release essential oils or H-BIOTICS probiotics to sanitise surfaces and create a more hygienic environment. The top of the range 700 comes with the diffuser and a humidifier.Unlike dust and pollen, listing all the chemicals in smoke would be almost impossible, but the rule of thumb is that no smoke should be inhaled and all particles can be harmful. Is smoke harmful? The diffuser feature can be really useful for households that experience a lot of smoke – the purifier can periodically release a pleasant aroma which can combat the bad smells created by the smoke – be it cigarette, cooking, fire burning or machinery. How to use an air purifier for smoke effectively The air purifier will reduce the number of these particles over time as well as remove the particles causing odour – this will make the air cleaner and neutralise the odour.
