Vacuum cleaners are an integral part of our daily lives. It is very helpful for us to clean the dust in our house. HEPA is a filtering system, a popular filtering system of vacuum is HEPA filtering. This is a very important consideration when it comes to vacuum selection if you are dealing with serious allergy problems or a house that is potentially contaminated with lead dust or mold.

HEPA vacuums are recommended for minimizing dust, dander, and other common allergens in homes where people suffer from allergies and respiratory. But it never gives you the absolute guarantee that it can automatically trap every dust in your house. What is HEPA filtration and their types can make our concept clearer

What is HEPA Filter

A HEPA filter (high efficiency particulate air filter), designed to remove 99.97 percent of all particles that are 0.3 microns in size that pass through it. HEPA filters are certified by a testing laboratory, but do not determine if it will stick to almost everything. The air flow does not maintain any rules for the rate at which the filter must be performed.

Manufacturers thoroughly test the filter before installing it in their vacuum and it removes air above about 75 to 100 cfm. However, the Europeans have applied the HEPA standard not just to filters but to the whole system. European HEPA standards have teeth and they’re enforced by European Common Market. The European standard is known as EN (European Norm) 1822.

We would recommend that if you are just thinking of a HEPA vacuum right now, choose the European standard.

Type of HEPA Filter

True HEPA-Filter

When you are planning to install HEPA filters in your vacuum to ensure trap allergies and get fresh air flow, it is important to choose the true HEPA filter. It must pass a standard to be a true HEPA filter. A serial number of true HPA filters has been assigned to them and has been shown to trap at least 99.97 percent of particles of 0.3 microns. As much as possible their test results are at their level. True HEPA filters can be a bit expensive but it must go through their specific criteria in practice.

HEPA-Type Filter

HEAP-Type Filters are built exactly like True HEPA filters and look like them. Notably, however, one of the ways to recognize them is that they do not exceed the true HEPA standard. Distorted HEPA-type filters on the market can trap about 75 to 90 percent of dust particles, and that percent can fall even lower for particles of one micron and below. And they do not follow the serial number.

How Does It Work in Vacuum?

We have already discussed the HEPA filtration system, a filtration that seals dust and dirt after trapping. To know how HEPA works in a vacuum cleaner we need to know the whole processing of vacuuming.

A vacuum usually collects dirt in two ways. Bagless and bagged. It first creates suction with their motor which pulls all the dirt from the surfaces and to do this they use a rotating brush to suck the dirt especially from the carpet. Although there is a separate brush for cleaning upholstery, the dirt accumulates in the bag or bin. The effectiveness of the filtration system plays a significant role here. After dust particles re-spread on the floor without filtration. If you have a good HEPA filter in your vacuum, it traps the dust particles, sealing their air flow so they can’t get out again.

HEPA filtration is very effective in trapping large dirt and pet messes perfectly. In most cases, this is enough for you. However, if you have severe dust mite allergies or a serious contaminant problem, you need to take a real HEPA filter It is possible to buy a vacuum that collects more than 99 percent of fine particles, but it will be expensive. However, HEPA that cannot trap 99% of dust and allergies are real HEPA and can release some dust into the air.
