Which is better HEPA filter or electrostatic?

HEPA Air Purifiers typically have an 87-99 percent first-pass efficiency rate, meaning HEPA Air Purifiers catch more particles faster. Electrostatic Air Purifiers have a 60-80 percent first-pass efficiency rate and require a longer amount of time to improve your indoor air quality.

Is electrostatic filter better than HEPA?

A true HEPA filter is 99.97% efficient on removing dust particles from 0.3 microns to 10 microns. A LakeAir electrostatic cell is 97% efficient on removing dust particles from 0.1 micron to 10 microns. These numbers are very similar. Based on the efficiency numbers alone the HEPA is clearly a better filtration type.
