About this deal

HEPA air purifiers: Standing for "high efficiency particulate air," air purifiers with HEPA technology use a fiberglass filter that traps particles of a certain size out of the air. 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. The Telegraph does not yet have a laboratory for accurately measuring air pollution (we’re working on it), so instead we relied on the advice of buyers at large department stores, who deal with the full range of air purifiers and know the pros and cons of each one. We were looking for the best filtration power at the best price, but also took into account looks, reliability, fan and air cooling functions and the reputations of the manufacturers. 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 may be at the pricier end of the scale, but the AEG AX7 must be the best-looking air purifier on the market. Ideal for living rooms, its five-stage purification system ensures the capture of up to 99.9% of all microscopic particles and bacteria and can clean the air in 60m 2 room in as little as seven minutes, while making no more noise than light rain.

Cutting your pre-filter is easy. Simply remove the pre-filter from its box and use the provided cutting template. Following the cutting template will ensure your pre-filter is the correct size for its untended unit. Once you've finished cutting, you'll want to secure the pre-filter under the clips located on the rear of the air purifier's grille. Why are there two filters in my air purifier? What are the differences?Honeywell S Series Filters are specially designed to strengthen the Insight™ Series. Honeywell Enhancement Filters provide a degree of customization to the filtering experience as they're able to target specific odors. The availability of four different enhanced filters offers a personalized approach to targeting most common household odors as well as VOCs specific to the surrounding air. Intended to be used alongside a standard Pre-Filter and HEPA Filter, Honeywell Enhancement Filters can expedite the removal of odors and VOCs in the surrounding air. Are air purifier filters good for wildfire smoke? 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). Note: These replacement intervals are intended as guidelines only. Performance of any filter media is dependent upon the concentration of contaminants going through the system. High concentrations of contaminants such as dust, pet dander, and smoke will reduce the useful performance of the filters. 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). Based on 3rd party independent CADR testing for the smoke CADR value when operated at the highest level. Air circulation depends on many factors, such as room size and configuration. There is no guarantee that all of the air in a room will pass through the filter.

HEPA Filtration: This home air purifier helps capture up to 99.97% of the following microscopic airborne allergens and particles: dust, pollen, pet dander, dust mite debris and smoke. 1 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. HEPA-Plus Filter is designed to provide even better filtration than a standard HEPA filter. It can remove up to 99.99% of airborne particles, including smoke, pollen, pet dander, and dust.Note: the main filters on Air Genius or Quiet Clean Air Purifiers are permanent and do not need to be replaced but should be washed every 3 months according to the instructions in the owner's manual. The biggest impact is on cardiovascular and respiratory health but there is evidence that air pollution can have widespread effects,” she says. “Exposure to air pollution during pregnancy, for instance, is linked to low birth weights and pre-term births. Particulate matter associated with road traffic has also been found on the placenta.”

To achieve this, we needed to find a way to produce a quantifiable and fairly repeatable amount of particles; an environment or "test chamber" in which these particles and the air purifier units would be contained; and an accurate particle counter that acts as our control device and allows us to visualize this data. Here's what we came up with: Coway Airmega 400S: Acceptable performance, very sophisticated filtration system, voice and app control, air quality monitoring via the app and color coded LED indicators on the unit. There are just better options for the price. This air purifier for allergies is AHAM (Association of Home Appliance Manufacturers) Verifide meaning that it has been independently tested to ensure its efficiency in reducing smoke, dust and pollen in the suggested room size. The AHAM assigns a CADR (Clean Air Delivery Rate) Rating that measures the volume of filtered air delivered by an air cleaner. The Honeywell HPA100 True HEPA Air Purifier received the following CADR Rating:

According to the US Environmental Protection Agency, some of these microscopic solids and liquid droplets, which can be made up of hundreds of different chemicals, are so tiny that it's almost inevitable to inhale them. PM10 and PM2.5, which are particles of less than 10 and 2.5 micrometers in diameter, respectively, pose the greatest risk to human health since once inhaled, they allocate deep into the lungs and even into the bloodstream, impairing the proper functionality of the lungs and heart. Coway Airmega AP-1512: Above average performance overall. Sports a color-coded air quality indicator, eco-mode, filter alerts and has an ionizer option that enhances bacteria and virus removal. Cleaning Levels (Microscopic Particles, General Clean, Pollen and Turbo) make this an excellent air purifier for allergies
