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

Why are people suddenly scrambling to get their hands on the best air purifiers? Poor air quality can lead to a range of health complaints. The problem is particularly acute in our cities: poor air quality outside can cause poor air quality indoors. I had hoped to grow out of these allergies, but I never did. And it was after I gave birth to my first daughter eight years ago that I also started to suffer from hayfever. What’s one more allergy to add to the list? Matt Thomas, Lead Small Electricals Buyer at John Lewis, has noted a marked increase in air purifier sales. “Typically, we’ve seen families with young children, new parents and families where there’s a history of allergies or respiratory conditions being the early adopters,” he says. First, make sure that you have the latest version of the app, that your Wi-Fi is working and that your air purifier is within range of your router (within 10 meters).

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. It was around the same time that I was diagnosed with asthma. I had many episodes as a child related to my allergies and my asthma. There were numerous occasions when I ended up in hospital needing treatment and help to breathe. It’s just as good as an air purifier too, though its CADR rating is slightly below that of the purifier-only Pro P2. In tests, it took PM2.5 levels from a maximum 411 micrograms per square metre to 25 in 135 seconds, bringing it down to double figures in just over a minute. Again like the Pro P2, it’s quiet, with the noise barely noticeable at the lowest speed in purifier mode. Left on Smart mode, with the front-facing display turned off, all but the lightest sleepers should be able to sleep through.

What we really like about this purifier, however, is that it’s both effective and pretty quiet about it. At full tilt, it’s as noisy as most rival air purifiers, but in its sleep mode you’d struggle to hear it above ambient sound levels – we measured the output at just 31dBA. In our deodorant spray test, the H-Purifier 500 got the PM2.5 concentration down to safe levels within two minutes and eight seconds, and Hoover’s three-filter purification system has been approved by the Allergy UK charity. We’re not 100% sure about the option to add essential oils to the airflow, but the options include an H-Biotics bottle that adds probiotic “good” bacteria to the atmosphere. All in all, it’s a superior purifier that’s perfect for mid-sized and larger rooms, with a price tag that won’t leave you gasping. As hayfever season hasn’t really started yet, I haven’t been able to fully test the 100% Pollen Neutraliser Technology which pulls in and traps pollen from the air, before neutralizing it. I will look forward to seeing how effective this is later in the year and I will update this post. Using the air purifier’s humidifier function Efficient 3-Stage Filter System】 The first defence primary filter can filter dust, pet fur, lint; The second defence H13 HEPA filter trap airborne particles such as pollen, pet dander. The last defence activated carbon stage can effectively filter out unpleasant smoke and odours. 3-Stage defences protect your each breathes 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 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.The best air purifiers for larger rooms 1. Hoover H-Purifier 500: Best quiet purifier for larger rooms
