HEPA filters are high efficiency units that can filter air up to 99,99% impurities. HEPA comes from English (High ANDefficiency Particulat Ago).
These filters are very effective with dust, mites, mold, pollen, bacteria and viruses.
HEPA filters are considered absolute! This is because they offer maximum efficiency in air filtration.
Where HEPA filters are used
HEPA technology is currently used in many appliances and appliances, in addition to industrial applications. It is common in ambient air purifiers, vacuum cleaners, filter dehumifiers and some air conditioning models.
These filters are also widely used in hospitals and aviation.
So if you have for example a vacuum cleaner or air purifier with HEPA, you have made a good bet. Yeah, so it guarantees a clean, healthy air inside the house. In addition, they are the most suitable for those who suffer from allergies or have respiratory problems.
Why use HEPA filters in vacuum cleaners?
If you think of a conventional vacuum cleaner, you know they can suck a lot of impurities. However, most vacuum cleaners do not have these filters, so they end up coming back out and contaminating the air.
This is why it is ideal to use a vacuum cleaner with HEPA filter. Yeah, they're great for floor cleaning, sofas, mattresses, pillows, carpets and curtains.
How do filters work?
HEPA filters are designed to retain tiny particles, unlike many conventional models. To this end, they use a special technology of fiber meshes. They also have at least 2 filter levels. Most have at least one prefilter to retain larger particles and then the mesh filter arranged randomly.
Simple HEPA do not filter smells or aromas, but for this purpose there are several models where an activated carbon layer is also added.
Maintaining a filter HEPA
Some filters can be cleaned with only one passage through water. However, many models cannot be washed or will lose their filtering capacity. In such cases, you should be able to clean the filter with air only. Ideally you should use compressed air and clean outdoors to avoid contaminating any closed environment.
Therefore, you should always check the manual of your equipment to see if and how to clean the filter.
