The Differences Between “Air Filtration” (HEPA) and “Air Purification” are like black and white.

Despite the logic of pure science, the world continues to push the false narrative to the contrary that filtration systems (HEPA Filters, In-Duct filtration and others) are able to cleanse and sanitize your indoor air environment.

Allow us to show you why this is virtually impossible. 
But first, please try to find where nature is dependent upon, or using filters (like HEPA filters), to create clean, fresh air. Well? We’re still waiting…

Lastly, do not forget to bring Fluid Dynamics and the current speed of indoor air into the equation: it travels at over 1100 feet per second. Now let’s discuss our two options for creating clean, fresh indoor air.

Let’s get started on the differences:



Air filtering refers to the process of removing contaminants from the air by passing it through a filter – usually via suction, which is caused by use of fans with varying strengths.

The filter is designed to trap and retain certain contaminants, such as dust, pollen, and smoke, while allowing clean air molecules to continue on and pass through each successive filters.

Even if the air filter can suck hard enough to try and get the air currents in the corners, behind the furniture, up on the ceiling, and other remote areas, it will still not be able to sanitize and cleanse the surfaces.

And we KNOW that is not going to happen, because of how air moves: First, it is moving at around 1100 feet per second indoors. Then, Brownian Motion, air vortexes, obstructions like furniture, people walking about, opening doors, cabinets or closets, natural slip streams and eddies of air current, and more, will keep many particles, pathogens, allergens, gasses and more from getting anywhere near the unit.



Air purification, on the other hand, refers to the process of removing a wide range of contaminants from the air.

This is typically done using a combination of techniques, such as ionization, photo catalytic oxidation, Lysis, UV radiation, and other chemical reactions.

Below is a simplified illustration showing how PRO-ACTIVE air purification sends out a sun-like air-cleansing plasma into the indoor air environment, cleansing the air from allergens, particles, VCO gasses and other harmful particulates.
