Recently produced modern models of vacuum cleaners are increasingly equipped with HEPA filters. Such devices deal with particles that can only be seen with a microscope.

History of Creation

High Efficiency Particle Containment - that's how the abbreviation HEPA is translated from English. The device and material of these filters allow us to classify them as fine cleaning devices.

They were developed in the last century, in the forties, when creating the atomic bomb project. The purpose of these filters was to remove radioactive impurities. After some time, the scope of cleaning devices has expanded significantly. They began to be used in mechanical engineering and in medical institutions, in the pharmaceutical and food industries, as well as in household appliances.

What is a HEPA filter? This high performance particle retention device is made from fine cellulose fiber. During the operation of the vacuum cleaner, dust settles on a network formed from the smallest pores. At the same time, even the smallest particles with a size of 0.3 microns are retained.

HEPA filter is made using a special technology. Its main principleis the pressing of layers of cellulose and their layout in the form of an accordion. This allows you to significantly increase the area of the filtering surface. The cellulose accordion is fixed with a reinforcing grid.

HEPA filter can be disposable. In this case, fiberglass is added to cellulose during its manufacture. The reusable HEPA filter is made from PTFE fibers.

Purpose

Filters for very fine cleaning are used when cleaning the room with a vacuum cleaner. They allow you to eliminate microorganisms and allergens. The smallest particles are also very effectively captured. This process is possible under the action of the following HEPA filter mechanisms:

- the effect of particles catching on microfibers;

- the effect of inertia, which is expressed for large particles;- the diffusion effect, which is most pronounced at low airflow speeds.

Can the HEPA filter be washed?

There are times when a rather unpleasant smell of dust appears when vacuuming. This may mean that the filter has expired and has ceased to retain particles for which it was designed. In order to correct the situation, it is necessary to replace the cellulose accordion with a new one. You can simply wash it. However, this procedure is only possible if the filter is of a waterproof type. The terms of replacement and cleaning conditions are indicated in the instructions for the vacuum cleaner.

Modern Samsung vacuum cleaners do not have dust bags. Basicgarbage and dirt settle in a special plastic container. In addition, the vacuum cleaner is equipped with two filters. One of them cleans the air when it is sucked in, and the other when it leaves the vacuum cleaner. This is a HEPA output filter for Samsung type H 11. It is waterproof. When dirty, rinse under running warm water at least two or three times a year.
