The abbreviation HEPA is an English acronym that stands for High Efficiency Particulate Air (filter). They consist of a dense fabric of randomly interwoven fibres that trap the smallest particles such as fine dust, pollen, mould spores and other allergens. HEPA filters are most effective for particles between 0.1 and 0.3 micrometres in size. HEPA filters cannot remove gases and odours. HEPA filters can be categorised into different filter classes.

They are particularly effective at removing gases and odours. Activated carbon is highly porous and has a large surface area that adsorbs pollutants such as smoke, bad odours or VOCs. However, activated carbon is not effective at filtering solid particles such as dust or pollen. Depending on the level of air pollution from gases and odours, activated carbon filters need to be replaced regularly, as activated carbon is quickly consumed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePre-filters\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMany air purifiers with filter technology have a pre-filter in addition to the main filter, which traps coarse impurities such as hair or dust.

If the air humidity is lower than 40 %, an air washer is recommended, as these also ensure optimum humidity and thus keep the mucous membranes moist, which can also alleviate the symptoms of allergy sufferers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre air purifiers useful against dust?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, air purifiers are effective in reducing dust particles in the air.

They are therefore effective in eliminating odours in indoor spaces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo air purifiers protect against viruses and bacteria?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eViruses and bacteria can be efficiently filtered out of the air with an air purifier. When used correctly, air purifiers can help to reduce pollutants in the air, including viruses. An air purifier helps to reduce the risk of infection from viruses and bacteria and can protect other people in the same room from infection.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between humidifiers, air washers and air purifiers?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAn air purifier is designed to remove pollutants such as dust, pollen, allergens and other particles from the air. A humidifier, on the other hand, is designed to increase humidity, which is particularly useful in dry air. An air washer is a combination of humidifier and air purifier. Air washers are particularly useful in dry and dusty environments.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"card-body\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Stadler Form","offers":[{"title":"White","offer_id":42134127837347,"sku":"R-015A","price":349.99,"currency_code":"USD","in_stock":true},{"title":"Black","offer_id":42134127804579,"sku":"R-015B","price":308.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0431\/2252\/4323\/files\/SF_Roger_little_white_new_iso.jpg?v=1778852745","url":"https:\/\/airpuria.com\/products\/roger-little-stadler-form-air-cleaner-for-smaller-spaces","provider":"Airpuria","version":"1.0","type":"link"}
