Since many countries have announced the quarantine and doctors recommend self-isolation, a HEPA air purifier helps lower the spread of the COVID-19 virus significantly.
For example, PurOxygen P500 Air Purifier comes with the HEPA filter. The brand claims that it captures 99.97% of the particles above 0.3 microns and 95%-99% - below 0.3 microns. Thus, potentially it can filter out up to 99 percent of the COVID-19.
The unit needs 2 hours to clean the air in the space of up to 550 square feet. Besides the COVID-sized viruses, it removes 99.98% of airborne pollutants that float in the air and settle down on surfaces. These are mold, dust, dander and other allergens. It also deals with smoke, bacteria and microbes. As for the placement, to make the performance as effective, as possible, it is recommended to keep the distance between the air purifier and any object in a room to at least 4 inches.
Besides, the model features a 6-level enhanced purification. It consists of 6 filters each working on neutralizing a particular type of contaminant. These are a pre-filter, the HEPA filter, the activated carbon air purifier (absorbs smoke and chemical reactions); the cold catalyst filter (decomposes different harmful gases), the negative ion generator (besides filtering, eliminates the debilitating effects of extra positive ions in the environment), and the UV light sanitizer (neutralizes germs, bacteria, viruses and allergens). This high-performance air purifier contributes to the overall protection of the immune system, whose state is a key factor of the resilience to COVID-19.
