HEPA air purifiers are the superior choice when it comes to air purification. They have a first-pass efficiency rate of 87 to 99 percent, which means that they capture more particles faster than electrostatic air purifiers. Electrostatic air purifiers have an efficiency rate of 60 to 80 percent in the first step and require more time to improve indoor air quality. HEPA (high-efficiency particulate air) filters use a fine-mesh material to capture particles and are much more efficient than electrostatic filters.
They remove 99.97% of dust particles in the 0.3 micron range, while an electrostatic filter removes 97% of dust particles. HEPA filters also have a first-pass efficiency of 87-99%, while an electrostatic filter has only 60-80% first-pass efficiency. If you want clean and uncomplicated air, it's clear that an air purifier with a HEPA filter is the right choice. The prefilter will absorb larger particles and save the life of the HEPA filter, which is usually the most expensive element in the machine.
If you want to spend less money and clean the filter yourself, your answer will be completely different from that of a person who doesn't want to clean the filter themselves. So, is an electrostatic air filter right for you and your home? HVAC manufacturers have been testing the effectiveness of filters in protecting people from contracting the virus. HEPA filters are easy to replace once or twice a year and don't require you to spend time cleaning them. If your family doesn't have a respiratory illness, you're a practical homeowner and don't mind cleaning the filter, an electrostatic air filter can save you money and still keep your home clean.
All I can do is warn consumers to stay away from any air purifier that doesn't include a HEPA filter.
