If you take away a vacuum cleaner from a modern woman, she will say that cleaning the house is impossible. But after all, our grandmothers used to do without this miracle device, and their houses were no dirtier than those of modern housewives. Have we been so spoiled by civilization?

No, the fact is that cleaning with a modern vacuum cleaner is very effective. It can remove dust from any surface, and most importantly, it does not get back into the room.

Today, manufacturers of household appliances from different countries offer a huge number of models of vacuum cleaners. The most expensive of them are equipped with fine filters. What is this device and what is it for?

HEPA filter is designed for fine cleaning and retention of microparticles. Initially, these devices were developed to equip the ventilation system in hospitals, medical centers and where increased air purity is required. This technology has become widespread in the West, and is widely used in the manufacture of air cleaners and vacuum cleaners.

BeforeWith devices of this type, vacuum cleaner manufacturers install several more coarse filters that retain larger dust particles. HEPA filters are able to trap microparticles as small as 0.3 microns and prevent them from re-entering the air. It should be noted that such particles are the cause of many diseases and allergic reactions. Therefore, asthmatics and people with allergies should install a HEPA filter on the vacuum cleaner.

They come in two types - disposable and reusable (washable). Disposable filters are made of paper, and reusable filters (they are much more expensive) are made of fiberglass or fluoroplastic. The latter can be washed and continue further operation. Despite the rather high prices, the reusable HEPA filter will have to be replaced after two years of use. Filters of this type are used in small household portable vacuum cleaners. In order to save money, they are made in the size of 50-200 cm square. When the HEPA filter reaches 20-25% of its life, its efficiency drops to 80% of its original level.

Special attention deserves the material from which the casing of the device is made. The main condition for its good work is a snug fit to the block. If there is no airtight seal between the housing and the filter, then the efficiency of its work will be equal to zero.

All HEPA filters are divided into classes. In accordance with the international classification, they are assigned numbers from 10 to 14. The larger the model number, the more efficient its work.

Some versions of modern vacuum cleaners already have a HEPA filter, others have the ability to install one.

Manufacturers often use "HEPA-like" or "HEPA-like" expressions to promote their products, which can be misleading to consumers.

You can buy a replacement HEPA filter in all stores selling household appliances of this level, or order it on the official website of the manufacturer.

Many buyers are worried about the following problem: will replacement HEPA filters suitable for their vacuum cleaner model disappear from sale in a few years. We can reassure you: manufacturers produce universal options that will fit many models.
