The first stage of filtration of the LV-PUR131S air purifier is a preliminary filter or pre-filter. This helps catch comparatively large particles such as hair, pet dander, kinds of lint, and so on. A pre-filter plays an important role in increasing the life of the HEPA filter. You have to clean (dry cleaning only) the pre-filter from time to time to ensure its good performance.

True HEPA Filter

Levoit LV-PUR131S comes with a True HEPA filter in the middle layer. There are many types of so-called HEPA filters is available in the market. Among all, the most efficient one is the True HEPA filter. It can trap 99.97% of contamination from the air as tiny as 0.3 microns. This effective range of the true HEPA filter is good enough for a regular indoor place such as home or office. You will feel the changes in the quality of air in your home when you use an air purifier with a true HEPA air purifier.

Activated carbon filter

This is the final stage of the filtration system of LV-PUR131S. The carbon filter does not work like an ordinary filter. It does not catch or trap the airborne particles. Instead, it removes the bad odor and smoke particles from the air. It is capable of removing cigarette smoke, pet odors, VOCs, kitchen odors, and so on. A carbon filter does not add any kind of chemical or natural smell in the air. It just removes smelly particles from the air and makes the air odorless so that you can breathe fresh air.
