What is an air cleaner HEPA?

Many air purifiers use highly efficient air particle filters, also known as HEPA filters, as the main filter systems. Air purifiers that use HEPA filters reduce the amount of allergens, dust and microscopic particles in the air. HEPA filters are known for their efficiency in capturing these airy particles. The actual air purifier HEPA is usually evaluated to remove 99.97% of air particles. Scientists in the Manhattan project have created the HEPA filter system in the 40th year of the 20th century to remove radioactive particles from the air in the laboratories. Over the years, the filters have been improved to some extent and are now used in clean rooms, hospitals and aircraft, as well as households and businesses.

There are two levels of HEPA filtration in the air. The first is the level true hepa or Absolute Hepa , which captures 99.97% of all particles that are 0.03 micron or larger. Vacted States, these filters must go through the testing process to see if they have tutby the level of efficiency to be certified as a real HEPA filter. Real HEPA filters usually have a serial number that means they have passed the test process.

The second level of the HEPA filter efficiency is the filter like or hepa . They either did not undergo real HEPA testing or did not meet its strict requirements. These filters are usually 85% to 90% effective in removing air particles.

The HEPA air cleaner filter is usually an accorded sheet of HEPA filter material. There are three main ways that this material in the air cleaner HEPA captures particles. First, larger particles are captured, almost the same way as the sieve captures the leaves, but allows you to go through liquid tea. This filtration process is called interception and is common between most air filtration systems.

Unlike many other filters filters HEPA is not just částice trap larger than the smallest filter holes. The second method of filtration in the HEPA air cleaner is called impact. Impaction uses the flow air flow in the HEPA filter to drive particles to the fibers. When the air passes through a fibrous leaf, it moves and moves to find the way. The particles monitor the current and are often captured in the process.

The third filter process used by HEPA air cleaner, called diffusion, captures the smallest particles, usually those at 0.1 micron. These particles are so small that they interact with air currents at the molecular level. They are caught when they encounter air molecules, bounce and hit the filter fibers.
