What is the difference between an air purifier and an air scrubber?

Since the pandemic there has been global concern over indoor air quality. The terms “air purifier” and “air scrubber” (a relatively new term) are being used a lot more and sometimes interchangeably. Both improve indoor air quality, but they have fundamental differences that we will highlight in this article.



The main difference between an air scrubber and an air purifier is the particles they clean. An air purifier is designed to clean airborne particles whereas an air scrubber can remove particles from the air and surrounding surfaces.


How does an air purifier work?


Air purifiers are usually designed to pull airborne particles through the equipment and filter them out within the purifier itself.


How does an air scrubber work?


Air scrubbers most commonly use negative ions that attach themselves to airborne or surface particles, thus making them heavier. In some cases, air scrubbers can take these heavier particles and filter them through an internal system.


There are two methods to scrub the air, dry and wet


If the air scrubber uses wet scrubbing, it pulls the air in and through a damp pad or filter to trap free-floating particles.


If it uses dry scrubbing, the machine sucks the particles through dry filters to clean the air, like a HEPA filter.


Some air scrubbers also remove odours using carbon filters and kill germs using a UV light.



AIRsteril an air purifier or an air scrubber?

AIRsteril products have been designed by specialists in air purification but their technology and process is arguably more in line with that of an air scrubber due to the negative ions.


AIRsteril units release negatively charged Superoxide Ions to attach to the airborne contaminants causing them to cluster together and fall from the air as they become too heavy. This can remove airborne particulates down to 0.0001 microns, that’s better than any HEPA filter on the market.


The AIRsteril however doesn’t require HEPA filters. The system freshens the air by killing airborne pathogens, viruses, bacteria, fungi, mould spores, allergens and by decomposing odours and harmful gases using a combination of air cleaning technologies.

Internal:

· Germicidal Irradiation

· PCO – Photocatalytic Oxidation

· Dual waveband UV

Transmitted Technology (Plasma Quatro):

· Superoxide Ions

· Targeted Ozone

· Purified Air

The AIRsteril technology combines sterilising, cleaning, and purifying technologies, including germicidal UV light, dual UV operation, Photocatalytic Oxidation (PCO) and a purifying plasma of superoxide ions and optimal ozone. First, it uses internal processes to purify the air, before releasing purified air and Plasma Quatro back into the room to continue working.
