Air Scrubber vs Air Purifier – What’s the Difference

Air Scrubber and Air Purifier

One cleans the air of fumes, construction dust, and removes odors; the other can kill the COVID-19 virus and keep occupants safe. A pretty big difference between air scrubbers and air purifiers, then, and you can’t afford to get the wrong one for your home or office.

Air scrubbers and air purifiers are two popular air purification systems. We’ll break down the differences between them and help you decide which is suitable for your building. 

Why You Might Need an Air Scrubber or Air Purifier

With the average person spending 90% of their time indoors, it’s vital to maintain a high standard of indoor air quality (IAQ). Yet, that’s not always the case. Every day, whether at home or the workplace, people are exposed to health hazards such as:

  • Cigarette smoke
  • Mold spores
  • Volatile organic compounds (VOC) 
  • Smog
  • Dust
  • Animal dander
  • Allergens 

All of these can have a serious impact on health (especially in the long term).

Air Scrubber vs Air Purifier – What’s the Difference? 

Though both devices are designed to clean the air in your building, there are significant differences in their purpose, design, and operation. 

In general, air scrubbers quickly remove contaminants from the air, while air purifiers are long-term solutions to sanitize the air. 

What is an Air Scrubber? 

Air scrubbers are a type of air cleaner. They scrub the air using various mechanical filters suited for the particular application they are needed for.

You’ll usually find them: 

  1. In heavy-duty industrial settings; or
  2. On residential and commercial sites, being used to remove construction dust, severe mold infiltration, and noxious fumes. 

Industrial grade scrubbers are of two kinds – wet and dry. 

Wet Scrubber

Wet scrubbers are generally for highly contaminated areas, like wastewater treatment plants. Contaminated air is pulled into the scrubber, then run through a water-soluble treatment compound, then pushed back out by fans.

Dry Scrubber

Similarly, dry scrubbers use a series of mechanical or negative ionization filters to draw in polluted air and release scrubbed air back into the building. 

What is an Air Purifier? 

The most popular choice to clean the air in your home or business is an air purifier. There are hundreds to choose from, each with varying airflow rates (how many square feet they cover), filtration processes, and other features.

Most use one (or a combination of) of these three technologies to clean the air: 

  • HEPA Filters

Designed to capture very small particles, these densely packed filters have been used reliably for decades to screen out mold spores, dust, pollen, and even viruses. These air filters remove particles from the air that can aggravate allergies, asthma, and spread diseases. 

Some purifiers include carbon filters to eliminate odors.

  • Negative Ionization 

Using negative ionization, an air purifier cleans the air by pulling in some of the building’s air molecules and adding an extra electron to them. 

These negatively charged molecules then stick to the positively charged pollutants and form a heavy molecule that will sink to the floor instead of being breathed in by occupants. 

  • UV Filter 

Ultraviolet filtration (UV light) is a highly effective way of destroying airborne viruses and bacteria. With more health measures in place than ever to ensure safety in indoor spaces, this purification technology has become indispensable. 

Air Scrubber vs Air Purifier – Which Is Better for Your Business?

Air Scrubber vs Air Purifier

Though nothing beats fresh air (as long as it’s actually fresh), air purifiers and air scrubbers have become essential additions to the HVAC system in our post-COVID-19 world. 

If you’re looking for the best option to keep your home or office air sanitized and protect occupants from stray viruses, an air purifier like CleanAir Tower could be the right option for you. 

While many air purifiers have just one or two filtration technologies, AirFixture’s CleanAir Tower combines all three. That’s why it’s ideal for use at home, in the office, and even in the classroom.
