The H.E.P.A. filters that we know about today were originally developed in the early 1940s and were used by scientists to prevent and trap airborne radioactive contaminant particles from becoming a problem.

Some time later in the 50s, these HEPA filters were later marketed for residential use and the term became branded and generally known as a term to distinguish any highly efficient filter to trap very small particles.

But because of demands for improved air quality in various high-tech businesses such as space travel, pharmaceutical manufacturing and hospitals, HEPA filters became widely used in these industries to help eradicate dangerous or unhealthy airborne particles such as dust, smoke, mould, pollen and later asbestos.

A \’True H.E.P.A. filter\’ must be capable of retaining at least 99.98% of particles as small as 0.3 microns in size. These are minute particles and are the most difficult to filter and trap. They are considered the most penetrating particle size – MPPS.

This type of filter comprises of a mat of randomly arranged fibres that trap the smallest of particles. If you are actively searching for the best H.E.P.A. vacuum cleaner, always look for one with a \’True HEPA Filter\’ installed because they have the only types of filters that can actually feature 99.98% efficiency for retaining particles 0.3 microns or larger.

Because of the excellent filtration abilities of HEPA filters, they are very effective at removing unhealthy particles from the air and from areas such as carpets, upholstery and bedding, and can help make the air we breathe much healthier too. Poor indoor air contains pollutants, chemicals, gas, dust mites, mould, and other harmful ingredients. Low indoor air quality can also cause symptoms such as running eyes, headaches, tiredness, congestion, and many more serious and acute problems.

Most HEPA filters are found in air purification systems and vacuum cleaners to catch very small particles of dust. Vacuum cleaners use HEPA filters as part of the filtration process, and they are very helpful for asthma and allergy sufferers, as the HEPA media filter is able to trap the fine particles that can cause asthma and allergy symptoms.

In general, for a HEPA filter in a typical vacuum cleaner to be efficient at particle entrapment, the vacuum cleaner should be designed so that all of the air that is sucked into the vacuum is passed through the HEPA filter, with none of the air leaking by it.

Two basic types of HEPA vacuums exist. There is the canister and upright vacuums where canister vacuums normally have smaller cases that can be pulled along and follow behind you as you vacuum your carpet. Usually a long hose is attached to the canister vacuum cleaner that will help you to clean hard to reach areas of your home. Canister vacuums also often feature detachable rug brush beaters that are more powerful when compared to those found on upright vacuums.

Upright HEPA vacuum cleaners consist of one single unit that may come with an attachment hose to help clean hard to reach areas with specialized vacuuming tools. Upright vacuums may leak dusty air back into your home, and since the rug beater bar is permanently attached to the vacuum\’s case, once this important component breaks, the entire vacuum will have to be replaced. But if your home is mostly carpeted, an upright vacuum may be a better decision as its beater bar can dislodge dirt and dust embedded deep in the fibres of your carpets.
