Unhealthy air quality in the home leads many people to invest in an air purifier. There are many different types and this can lead to confusion about which model is the best to buy. HEPA air purifiers have many advantages and they will be the subject of this article. This is the most efficient air purifier available on the market today and this has led to it being the most preferred type to buy.
The acronym HEPA represents High Efficiency Particulate Air. This type of filter is unique because it is required to meet the standards of air purification efficiency laid down by the United States Department of Energy, (DOE). HEPA filters come in different classes but those available commercially are all designed to extract at least 99.97% of airborne particles down to 0.3 micrometers in diameter and can actually filter particles down to 0.01 micrometers. There are many types of particle that come into this category which is why HEPA air purifiers are so popular. This means that they are used in equal numbers by people who have an allergy and by people who just want to remove smells or dust from their homes. The purification process is done by using a fan to blow air through the filter; most models have several fan settings.
The kind of particles in the air depends on where you live and your lifestyle. Most homes will have dust mite allergens, pollen, bacteria, plant spores, mold and fungi at one time or another. Some homes will also have tobacco smoke and pet allergens. All homes will suffer from household odors and gases from time to time. These might include pet litter, cooking odors, various toxins, tobacco smoke and gaseous pollutants from detergents and cleaning materials. HEPA air purifiers are very efficient at removing these undesirable pollutants from the room.Quite a few HEPA air purifiers also include an ionizer, which will work on larger particles in the room giving a comprehensive air cleaning effect. The ionizer causes ions to build up on larger particles until they fall under the influence of gravity. They can then be simply removed by dusting or using a vacuum cleaner.
In summary, a HEPA air purifier will efficiently improve the quality of air in your home or office. They can be operated all day in the worst cases or just at certain times in order to remove odors or to perhaps to help you sleep. The best air purifiers to buy are the ones that have permanent washable filters since these help save a considerable amount of money that you could spend on something else.
