True HEPA Filtration


Common Misconceptions

Clever marketing has flooded the market with filters that are not effective at filtering the air you breathe. Claims like HEPA-Type, HEGA and more are creative ways to hide that a filter doesn't meet industry standards. 

True HEPA 

A High Efficiency Particulate Air (HEPA) filter must satisfy certain standards of efficiency, according to the United States Department of Energy. 

In order for a True HEPA filter to meet this standard, it must remove 99.97% of particles from the air as small as 0.3 microns in size. 

Hard to visualize how small a micron is? Check out our chart below:

A filter's efficiency refers to how many particles are trapped and removed from the airflow passing through the filter. At 99.97% efficiency, only 3 particles escape from every 10,000 passing through the filter. True HEPA filtration captures smoke, dust, pollen, pet hair and dander, mold spores and dust mites. 


While HEPA-Type filters appear to be similar to True HEPA filters, they are not standardized and cannot match the performance.

HEPA-Type filters don't typically disclose the size of particles filtered. They may claim to filter 99.9% of particles, but they don't say how small those particles are. They may only filter out larger particles, but allow smoke and mold spores to get through and enter your home again.
