What is HEPA Filter and Why Vacuum Cleaners Equipped with It?
A HEPA filter is a type of fine air filter. HEPA means high-efficiency particulate absorption, that is, highly efficient dust retention. Used in vacuum cleaners and air purification systems. The HEPA filter is usually made of pleated filter material which is folded. They are designed to filter small particles. This type of filter is especially relevant, for example, if your apartment is after renovation and protects it from a dust mite. In a vacuum cleaner, this filter is a guarantee of clean cleaning and a protector of your health. Filters and spare parts. So, let’s why it is better to have it, in this article made by our team.
Functions of HEPA filters
This filter is needed to clean the air from dust. The main difference between the HEPA filter and the usual one is that the HEPA filter is installed in the vacuum cleaner in the path of air exit from the device, and not at the inlet. From this, it follows that it finally cleans the outgoing air from micro dust particles, which, as a rule, contain various allergens (pollen, dust mites, animal hair, etc.). When you are cleaning an apartment, a lot of dust rises. But if you use this HEPA filter, you can get rid of it thoroughly. The presence of this filter in the vacuum cleaner is also mandatory if you have people in your house with any type of allergy.
Types of HEPA filters
HEPA filters can be divided into groups.
Disposable HEPA filters are made of fiberglass and antimicrobial paper. Such filters are most often found in cheaper models of vacuum cleaners since their cost is not high and such a filter does not pass dust particles down to 0.3 microns.
Reusable HEPA filters are made of fluoroplastic filled with porous activated carbon. These filters are washable and can therefore last longer than paper filters.
Particles of a larger size negatively affect the characteristics of HEPA filters, since they constantly knock out of their places already retained small particles, which leads to a significant decrease in the percentage of filtration efficiency. Also, large particles quickly clog the pores and air channels formed by the microfibers of the HEPA filter. This leads to an increase in the resistance of the filter to the airflow.
How to clean HEPA filters?
Even if you are very careful with your HEPA filter, sooner or later the question will arise about how and when it should be cleaned. If you have a vacuum cleaner with a disposable HEPA filter, you can blow it with compressed air (in the opposite direction). However, in most cases, this is useless, as micro dust particles are trapped in the filter fibres and cannot be cleaned. Filters are washed under the strong pressure of running cold water without the use of any detergents, you also do not need to rub them with a brush so as not to spoil them. Only dry it at room temperature. Consider the fact that reusable HEPA filters have a limited shelf life as well as disposable ones, as the pores of activated carbon become saturated and clogged over time.
As a result, it must be said that the presence of a HEPA filter in your vacuum cleaner is not a luxury, but a necessity that will keep you healthy and prolong the life of your device. To find a vacuum cleaner with a HEPA filter, visit the Shark website.
