Best Air Scrubbers FAQs

What is an Air Scrubber?

An air scrubber is a portable device with filters that sieve out airborne particles or contaminants in a particular space. The device clears out dust, pollen, mold, and other particles from the air, improving the quality of the indoor air.

It works by drawing air from the given area and passing it through its two or three-stage filter to capture the particles and then blows out the clean air. The size and filter operations of a HEPA air scrubber used in an environment are determined by the size of the area and the types of pollutants in the area.

Air scrubbers find applications in homes, offices, commercial outlets, and industries. Indoor pollution is typically more than two times the pollution outside. With air scrubbers, the indoor air is rid of contamination, giving a refreshingly clear air.

How Does an Air Scrubber Work?

An air scrubber is a negative air machine that captures airborne contaminants and improves the quality of air in a particular environment. Contaminated air can lead to allergies and other health complications. Using an air scrubber will enhance the quality of living, improve job quality, and lower remediation costs.

This portable filtration system captures airborne particles, removing up to 99.97% of particles in the air that passes through it. The HEPA filter traps dust, asbestos, bacteria, pollen, lead, mold, and other airborne particles. It draws in air, and the air passes through the different filters, and the particles are removed.

air scrubber usage

What is An Air Scrubber Used For?

An air scrubber is an air purifier, filtering the air of particles greater than 0.3 micrometers. It usually has a two-stage filter with an optional carbon or odor filter. The first stage filter captures large particles in the air that travels through it, while the HEPA filter captures smaller particles.

Air scrubbers are particularly useful in removing gases, chemicals, toxins, and other harmful substances from commercial and industrial environments. It is an industrial air cleaner for sewage and water treatment, construction, renovations, and remediation projects.

The device purifies the air, potentiating long-lasting health benefits.

Is the Air Scrubber Safe?

An air scrubber machine is an entirely safe device. The RA 650 Scrubber, for example, is C–ETL-US Certified and complies with testing, ozone, and electrical safety regulations. Some air scrubbers are ozone-free, while some use small levels of ozone, below the United States EPA exposure benchmarks.

Air scrubbers eliminate dust, pollen, bacteria, and other harmful particles from indoor air, providing clean and safe atmosphere for breathing. This contributes to the overall health of the user. So, the air scrubber is not just reliable; it ensures safety.

Do Air Scrubbers Remove Mold?

Yes, the devices remove mold. Many users report effective use of air scrubbers for mold spore removal. However, its effectiveness in mold remediation depends on several factors, especially the total amount of air exchanges per hour in a particular environment. It’s essential to know the air capacity of the environment or area and the size of air scrubber that can filter that air volume.

Air scrubbers are an excellent option if you want to get rid of mold spores that are potentially harmful to your health. Whether the mold spores are visible or not, the device will effectively eliminate them.

How Long Should You Run an Air Scrubber?

How long you run an air scrubber depends on the size of the area. Before purchasing one, it’s recommended you calculate the dimensions of the area. The size of the area will determine the size of the air scrubber you’d buy. To get the average time to run your air scrubber, divide the size (in cubic meters) of the area with the unit size of the air scrubber.

The standard guideline is running an air scrubber for 24 – 48 hours at four air exchanges per hour. This is, however, the minimum standard, as you might have to run the air scrubber for longer to get better results.

What Size of Air Scrubber Do I Need?

Choosing the right size of air scrubber is a vital step in meeting your air scrubbing needs. Picking up the right size will ensure it works maximally in your home or any area you intend using it. The first thing to do is deciding where you want to use the air scrubber. Is it your room or the entire house? When that is done, the next step is measuring the size of area or space, in square foot or cubic meters.

After getting the size of the space, the next point of action is matching it with the rating of the air scrubber. It’s recommended you get an air scrubber that has a rating exactly or slightly higher than the square foot of the area.

What is the Difference Between an Air Scrubber and an Air Purifier?

Air scrubbers are portable filtration systems that clean out airborne particles, ensuring clean, fresh air in the given space. They have a pre-filter that captures large particles, and a primary filter that captures smaller particles and harmful substances in the air.

An air purifier typically fits into HVAC systems and purifies the air just like the air scrubber. It rids the room or given space of airborne particles and harmful chemicals. Both the air purifier and the air scrubber have a HEPA filter that filters out microbes and particles up to 3 micrometers.

While there are no vast differences between both machines, the air purifier is a better choice for homes or environments with asthmatic or other respiratory issues. The fact that the air purifier can be conveniently fitted into your HVAC system is another noteworthy difference.

Buyer’s Guide: How to Choose the Best Air Scrubber

In choosing the ideal air scrubber for your domestic or commercial use, there are several factors you must consider. A pleasant air scrubber will perform at optimum capacity, and be of the best quality. It must be able to fulfill the purpose it was purchased for. Here are essential tips that’ll help you choose the best air scrubber.

Filtration System

The filtration system of an air scrubber is an essential part of the device because it traps particles from the air that travels through the machine, leaving only fresh, clean air.  The quality of the filter determines the performance of the air scrubber.

So when choosing a filter, go for the one with a high particle holding capacity and longevity. You should also go for the one that has a very low airflow loss. While most filtration systems use three-stage filters for particle and odor filtration, one with a fourth stage filter for gas filtration is far beneficial. We recommend the XPOWER X-2580 for its four-stage filtration system.

Type of Blowers

A quality air scrubber is equipped with a powerful blower that prevents the buildup of debris on the machine filters. When there’s too much dirt on the machine filter, airflow resistance sets in, and the effectiveness of the air scrubber becomes ill-affected.

Blowers are designed for various use cases. There’s airfoil blower designed for air scrubbers because of its ability to overcome the drop in pressure of dirty filters. This type of blower enhances the machine’s airflow and contributes to its durability as dirt starts to build upon the filters. For this feature, we recommend the OdorStop OS500, as it comes with powerful blowers.

Portability

Depending on your line of work or your reason for getting an air scrubber, you might have to go for a very portable one you can easily tuck in the most remote places. One of the significant features of an air scrubber is its portability. Look out for light-weight portable air scrubbers you can quickly move from one place to the other, without looking for multiple hands. Our best option is BlueDri BD-AS-550-BL because it’s easy to move around.

Airflow

The choice of an airflow rating will depend on the size and type of the given area. If you intend to get an air scrubber for your house, 500 CFM airflow will do the job effectively. However, a large commercial or industrial area will require a much higher airflow rate. It’s important to note that the rate of the airflow is directly proportional to the size of the air scrubber. What is crucial, however, is getting a machine with airflow equivalent to the size of the area, and the purpose it intends to serve. For this feature, we’d easily go with B-Air RA-650 for its tremendous airflow.
