Air purifier filter

The Trebs 49201 air purifier filter is a HEPA H13 filter for the Trebs air purifier 49200. This replaceable HEPA H13 filter ensures that 99.97% of the allergens in the air are removed. For example, it can relieve asthma symptoms. After intensive use, the filter should be replaced, so you can continue to provide clean air in the house. What is a HEPA filter HEPA originally comes from aerospace. Now this technique is also used in air purifiers to filter pollution from the indoor air. HEPA stands for: High Efficiency Particulate Air. HEPA filters are air filters that, depending on the type of filter, retain a minimum of 85% and a maximum of 99.999995% of all dust particles (most penetrating particle size) of 0.1 micrometer (µm). HEPA filters are classified into different classifications. Classification H13 indicates a filtration of 99.75% and 99.97%, so all dust particles larger than 0.1 micrometers (µm) are retained. How does a HEPA filter work A HEPA air purifier contains a fan that moves the air. First, the air is sucked in/attracted. This air then passes through the HEPA air purifier and filter and is filtered from dust particles and blown back into the room. What can a HEPA air purifier filter? A HEPA air purifier filters particles as small as 0.1 microns from the air with an effectiveness of 99.97%. One micron is one millionth of a meter (so very small). A hair is about 70 microns thick and just visible to the naked eye. A HEPA air purifier removes many types of contaminants from the air, such as coarse dust, fine dust, components of smoke, mold, viruses, bacteria, aerosols, pollen, dander and allergens from house dust mites. A HEPA air purifier needs periodic maintenance to keep it working properly. The HEPA filter becomes contaminated by use, so that it must be replaced at some point. To maintain clean air, it is necessary to replace the HEPA filter regularly. Used HEPA filters are not reusable and are disposed of as waste after use. What's in the box? • HEPA H13 Filter
