What is HEPA vacuum cleaner?

Highly efficient air vacuum (HEPA) Air (HEPA) contains a filter system that permanently removes the smallest of the airy particles without creating any type of by -product from the process. There are three types of filter vacuum on the market: truth or closed HEPA vacuum cleaners, unopened HEPA vacuum cleaners and vacuum cleaners similar to HEPA. Certified, true or closed HEPA vacuum cleaner has a closed filter system and is often recommended for those who have respiratory conditions. The models are launched as HEPA vacuum cleaners, but whose filter system is open, they have an authentic HEPA filter, although the captured particles can escape. Vacuum marked as hepa-like can have a filter similar to HEPA, but it is that does not meet the certification requirements as a real HEPA vacuum cleaner.

All actual HEPA vacuum cleaners must capture 99.7% to 99.9% of air particles as small as the size of 0.3 microns; The HEPA certification will be given by the vacuum. In Europe, the certified HEPA vacuum cleaner is referred to as grade 13 or 14 HEPA. CeThe merged seal HEPA vacuum cleaner is designed so that all air entering the vacuum has to pass through the filter system before leaving the machine. All air particles captured by this type of vacuum cleaner remain inside the vacuum until the filter is cleaned or emptied. That is why doctors often recommend closed HEPA vacuum cleaners for patients with asthma, allergies and other health conditions of the airways.

HEPA closed vacuum cleaners can use one filter or multiple filters. In order to function the vacuum properly, the filter should be removed at least once a year. Some filters can be washed and other one -off. Repeated filters are initially more expensive, but can save the buyer's money in the long term.

Some vacuum uses real, certified HFILTRY EPA, but lack a closed filter system. This means that vacuum can pick up 99.7% to 99.9% of air particles so mAlets like 0.3 microns, but some of these particles may end up in the environment. The reason is that all air is not forced to pass the filter before the vacuum. The system is leaking and the air can escape from any cracks as soon as it enters the vacuum.

There are also vacuum similar to HEPA with labels that claim to capture 85% or 90% of air particles as small as 0.1 micron. These vacuums may look quite similar to a real certified HEPA vacuum cleaner, but the filters in these machines have not passed the same strict testing. The particle size 0.1 micron, which picks up these vacuum cleaners similar to HEPA is not as small as what the certified seal HEPA vacuum cleaner can remove. This means that the consumer may not be able to remove mites and pollen from the home, which may not be the best choice with allergies or other conditions for some.
