Product Information

My allergies started around age seven from what I can remember. They came on seemingly out of nowhere. It started when I realised that being around animals made me poorly. If I went to someone’s house and they had a cat or a dog, my throat would get really sore, my eyes would start streaming and get unbearably itchy until they would swell up and I could barely see. I would sneeze incessantly and after a while, my windpipe would get tight, I would start wheezing and I would have real trouble breathing. Noise is another factor – you don’t want to replace one irritation (allergies) with another (the sound of a jet plane in your room). For many, the hum is something that doesn’t bother them, but some purifiers can get very noisy. It’s also worth remembering that, while some machines are quiet on their lowest setting (where they’re often at their least effective), they might be loud on the fastest (where they’re working at their best).

An air-quality sensor, which enables the machine to switch itself on when the air quality becomes poorer, can be useful. After all, you can’t see when the air quality dips, for example, as the result of a high pollen count. Ultra-Quiet Sleep Mode】 No light, no noise, just air purification! Sleep soundly while the air purifier works as quietly as 22dB for light sleepers. Sleep Mode automatically turns off display lights and reduces noise levels In terms of what to expect on the noise front then, if you’re running it at the standard mode, then Hoover’s official figures are 50dBA. Move it into the Sleep mode though and this goes down to 21dBA, which isn’t bad at all if you’re going to need to keep the unit running at night.

Issue

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.

What is generally present in smoke are carbon monoxide, carbon dioxide, sulphur dioxide volatile organic compounds (itself a category), carbon, ash and soot – particles which can damage the airways and lungs. Speed settings. Most air purifiers have a choice of speeds so you can keep it lower for sleeping and turn it up when the pollen count is high. A night mode can also help if you want a quiet setting and dimmer lights while you sleep, although we found this doesn’t always work as well as you’d hope. If the fan is set to its highest, the Dimplex can wipe out the pollutants and smells in your room in just 15 minutes. Handy if you’ve just been cooking. At its lowest setting, it’s very quiet – albeit not as quiet as the Blueair – and there’s a night mode that turns off all its lights until daybreak. Otherwise, this has the same advantages as the smaller version: effective three-stage filtering, a built-in humidifying function and Sharp’s Plasmacluster ion technology, which – while it sounds like a weapon from a Halo game – works to kill odours, bacteria and mould. While the Vax PureAir 300 gives you even more airflow and covers larger rooms for less, the Sharp hits a sweet spot for price, performance and features, making it a great mid-range purifier for mid-sized rooms.An air purifier works best when it is on all-day long in pollen mode. However, the air purifier will have to work harder if new pollen is being brought into the house constantly. Therefore, to make best use of your new air purifier follow these tips:

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. 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. Bring the air purifier into the room in advance for when there will be planned smoke – cigarettes, cooking etc A Swiss manufacturer we’d not come across before, Stadler Form launched their first product, the odd-looking Fred humidifier, in 1998 and now produce high-quality fans, heaters, dehumidifiers and air purifiers. Our favourite is this one, Roger Little (there’s also a Roger Big for 104m 2 rooms and plain old Roger for 66m 2 rooms).Considering an average UK living room of 20m2 (with a height of 2.4m), based on LABC UK data and a CADR of 330.

The H-PURIFIER range of air purifiers have a uniquely treated HEPA (H13) filter which not only captures the pollens but actively neutralises them*, making them harmless to allergy sufferers and preventing the allergic reaction (allergic rhinitis).

Which H-PURIFIER is best for smoke?

There is also an active carbon layer that traps and absorbs gaseous pollutants (VOC, NO2), fumes, cigarette smoke and odours.
