How do air purifiers work ?

1.How do E.S.P. Air Purifiers Work
  E.S.P. standard for Electrostatic precipitators.
  Electrostatic precipitators air purifier is a "filter-less" air cleaners. It is also known as an electronic air cleaner.

  Electrostatic precipitators have positive and negative charged plates. Particulates collect on the plates as they pass through the air purifier. Rather than having to replace the filter, you must wash or clean the plates. An electrostatic precipitators‘ performance is best when the plates are clean. When the plates become dirty, It’s time to clean the plate.

  Electrostatic air purifier produces small amounts of ozone as a by-product (within requirements set by UL 867). Ozone can kill germs, deodorize and freshen the air. Ozone Power (O3) < 0.05 ppm. For someone with a sensitive system such as COPD, emphysema or asthma, it is better to choose HEPA filter air purifiers.

2.How do HEPA air purifiers work
  HEPA stands for “High Efficiency Particulate Air.”
  A HEPA filter must capture 99% of all particles that pass through it that are 0.3 microns or greater in size. HEPA is composed of a layer of randomly arranged fibers. HEPA filters are often used in airlines, vacuum cleaners, cars, etc.

  HEPA air purifiers use mechanical filtration to capture particulates such as dust, pollen and smoke from the air. Over time the efficiency of a HEPA air purifier will improve.

  HEPA air filters need replacement at some point. This is for the sake of ensuring you are getting a high level of air cleaning. As the filters collect particles like pet dander, mold spores, pollen, and other airborne allergens, the airflow resistance will increase. This results in less airflow through the filter and lower air cleaning performance. If the filter is clogged it will have a difficult time in moving the air to clean your room.
