A HEPA air purifier is a great, trusted choice for anyone looking to remove allergens or airborne irritants. Originally created by nuclear scientists to help remove dangerous particles from the air, HEPA technology is now used widely in domestic and office environments.
Here we present a range of air purifiers with either True HEPA or HEPA-type filters, suitable for a variety of budgets and room sizes.
‘True HEPA’ filters remove 99.97% of particles down to 0.3 microns. ‘HEPA-type’ filters are generally cheaper and may offer a similar performance, but their efficiency can vary. Read more information about choosing a HEPA air purifier below....
HEPA filters are composed of a layers of media made up of randomly arranged fibres. The fibres are typically made of fibreglass with diameters between 0.5 and 2.0 micrometers. The air space between HEPA filter fibres is typically greater than 0.3 μm. The filters trap particles through a combination of mechanisms. Particles will either physically not "fit" through the filter or they will "stick" to it as they enter.
HEPA stands for ‘high efficiency particulate arrestance’. This acronym refers to a filter that is manufactured, tested, certified, and labeled in accordance with current HEPA filter standards. HEPA filters are the most common filters in use. They deliver high levels of filtration and are very dependable.
You can find either True HEPA or HEPA-type (or HEPA-like) filters on the market. The minimum True HEPA filter standard requires the filter to capture 99.97% of the 0.3 micron particles in the air passing through the filter. Performance levels of the alternative HEPA-type filters can vary. They typically remove 99% of particles between 0.3 and 3 microns which will be sufficient to deal with most particle filtration requirements in your home.
Sometimes a HEPA-type filter is all a person needs to tackle airborne allergens and particles and feel more comfortable. If you require even more efficient filtration which removes even very tiny, fine particles, a True HEPA filter is a superior choice. If you can afford it, we advise you choose an air purifier with a True HEPA filter as they leave you with cleaner air.
Air purifiers with True HEPA filters and HEPA-type filters remove pollens, dust mite debris, mould spores, pet dander, smoke, odours and some chemicals for a healthier home or workplace environment. Make sure you check the specifications on the product you are interested in, to ensure it deals with the particles you wish to remove from your air.
