How It Works

How Do Media and Electronic Air Cleaners Work?

Media & Electronic Air Cleaners

  1. Particulates and other offending odors fill the room. 

  2. Air Cleaners are turned on

  3. Air units scrub the air by throwing air against the wall creating a Coanda Air Effect and circulates the air in the room.

  4. The Coanda Air Effect brings stagnant/dirty air towards the unit which begins the cleaning process.

  5. Air passes through the unit and is cleaned through pleated filters and activated carbon (media); or passes though a electronic cell (electronic) and is then exhausted back into the room to be reused.

Electronic Air Cleaners

As dirty air particles race through the air cleaner, they first encounter high voltage (over 8,000 volts!) ionizing wires.  The intense voltage gradient creates vast numbers of positive ions. These positive ions bombard airborne particles in the airstream and become attached to the particles as “hitchhikers.”  As the now-charged particles pass between our tightly spaced, charged collector plates they are irresistibly attracted to the oppositely charged plate.

Media Air Cleaners

Media air cleaners use pleated paper filters. Modularity allows you to customize an air cleaning solution. To capture particles choose from a variety of filters of different efficiencies from common particulate cleaning to Hospital grade filters.

Sorbent Gas Phase Filters

Gas Phase filters (a.k.a. CPZ) are used in either the electronic or media air cleaners. These gas phase filters are able to capture odors, gasses, and other volatile organic compounds (VOCs). Air-Pure System's  gas phase filters use high quality, activated carbon and potassium permanganate pellets. These filters can be customized to the customer's requirements.

Media vs Electronic Which One?

When it comes to purchasing an air cleaner there are so many combinations and cleaning types it can quickly become confusing. When it's time to make a decision remember to think of the application.


- If you are trying to filter out oil mist from your machines or other particulates that would be hard for a paper filter, you would decide on electronic cleaning.

- Office and other similar settings which worry about outside particulates should choose a standard pleated media are cleaner to capture common particulates such as hair, dust, pollen etc.

- For offensive odors, gasses, or VOCs you would choose the media/electronic air cleaner with the activated carbon and potassium permanganate.
