Hepa Air Purifiers

An air purifier in an important device to have around the home, they can make a significant difference to the quality of air you are breathing. A HEPA air purifier can help enormously if someone in your family has a respiratory condition or suffers from certain allergies. This article aims to discuss the benefits of installing a HEPA air purifier and how the air filter actually works.

HEPA is an abbreviation to describe a ‘High Efficiency Particulate Arresting’ filter, originally designed in the 1940s by the US military to prevent the spread of airborne radioactive particles. HEPA air filters are now commercially available for the home, but the same technology is used for high-spec industrial air filters where high quality, pure air is essential in various industries such as pharmaceuticals, computer chip manufacture and hospitals. One common application of the HEPA air filter is in the domestic vacuum cleaner. To avoid the release of unhealthy dust and other particles into the air during operation, almost every vacuum cleaner on the market today has a small built-in air filter.

There are a variety of air filters available on the market today, some more efficient than others. HEPA air purifiers are widely regarded as the best solution to provide the most efficient form of air filtering; the HEPA certification is the industry standard. HEPA filters are made up of a pad containing many fibre layers that trap the tiny particles that are pulled into the filter system. It can efficiently remove at least 99% of the minute airborne particles including dust, dust mites, pollen and some bacteria. When the particles are caught in the filter, the air purifier blows the clean air back into the room, this is much more pleasant to breathe in! A HEPA air filter pad is removable, and will need replacing over time as the dirty particles build up and the air filtering becomes less efficient. Some of the newer models contain a washable pad that can be taken out, cleaned and replaced.

When choosing a HEPA air purifier for your home, it is important to do some research because there is such a variety of appliances available to buy. They come in various sizes from small portable units to larger freestanding models. You need to ascertain the size of the room where the air purifier is to be located in order that you can purchase the correct size to efficiently filter the air in the room.
