For projects and applications that require controlled environments and filtered air, air scrubbers and negative air machines are commonly utilized. Although the two are often referred to interchangeably as if they provide the same functionality, there are a number of differences that set them apart. In the following, we’ll dive into those differences and explain the common applications for rental air scrubbers and negative air machines. 

What are Air Scrubbers?

Air scrubbers are machines that are used to remove unwanted airborne particles through a specialized filtration process. Also known as air wash units, commercial air purifiers, HEPA air scrubbers, and portable air scrubbers, these machines are effective at removing a variety of contaminants. These included mold, chemicals, VOCs, smoke, bacteria, odors, and more. These units generally range from 250 cubic feet per minute, or CFM, up to larger units in the 2,000 CFM range.

What are Negative Air Machines

Similar to air scrubbers, negative air machines help remove unwanted and potentially dangerous particles from the air through a series of filters. They are also used to create negative pressure isolation rooms to contain airborne contaminants, like dust, fumes, molds, and even viruses as seen during the Covid-19 pandemic. 


These units, by creating a negative pressure environment, help contain those particulates within a specified area. By maintaining this negative pressure, an inward airflow is created, preventing contaminants from entering other areas. 

What are the Main Differences Between Air Scrubbers and Negative Air Machines?

Although these two pieces of equipment perform similar functions, there are a few key differences that are important when deciding which is best to rent for your particular project. For one, air scrubbers are more portable than negative air machines. Negative air machines are most often used at large job sites and projects, require more labor to move, and are usually stationary in nature. Air scrubbers are often on the move and not stationary. Their smaller size and weight make them a preferred choice for smaller job sites and where portability is paramount. 


Next, negative air machines use ducting to release the unwanted air from the particular room or area being worked on. Air scrubbers, though, do not use ducting to release air, but rather recirculates it. 

What Commercial and Industrial Applications Rent Air Scrubbers and Negative Air Machines?

Mobile Air & Power Rentals rents air scrubbers and negative air machines for a wide variety of commercial and industrial applications:


  • Restoration projects (water, fire)
  • Renovation projects
  • Asbestos and mold abatement jobs
  • Construction sites
  • Building remediation
  • Hospital applications (virus infection air control, isolation rooms)
  • Diagnostic and treatment rooms
  • Biohazard removal and more


As you can see, air scrubbers and negative air machines can serve a variety of useful purposes. For many projects that have shorter term needs, renting the equipment is often the most economical option. When doing so, working with a trusted industry leader will ensure the right equipment is chosen to ensure safety and optimal working conditions.
