The word HEPA stands for high-efficiency particulate air. The best thing about a HEPA filter is that it can remove up to 99.97% of microscopic pollutants in the environment. This is entirely true.
Air Purifier vs. Dehumidifier, An air purifier propagate the air through a filter which traps atmosphere -borne pollutants and irritants like dust, pollen and smoke. A dehumidifier stinks in moisture and decreases the humidity levels from the atmosphere, killing mold and germs that flourish in moisture.
