Best Air Scrubber for Mold [Comparison of Top 5 Air Scrubbers]

Best Air Scrubber for Mold

Polluted air can cause health hazards, including headaches, sore throat, chest tightness, nausea, and other respiratory diseases to you and your family.   

Mold can occur in any area, environment, or condition, whether in a warm or cold season. It is a fast-growing and aggressive fungus that can take over a home if not tackled early.

It may lead to poor indoor air quality, damage to the surface, and health issues for the occupants exposed to this unhealthy air. If mold spores contaminate the air around you, there are devices you may use to remove them from your home and environment permanently.

An air scrubber effectively removes mold spores from the air. It also tackles different problems in the home, such as scrubbing the air after a fire incident, water damage, or during and after a house renovation.

An air scrubber cleans, freshens, and purifies the air in your home by capturing and eliminating mold spores, odors, dust, pet dander, mildew, and other contaminants.     

You may ask: Is an air scrubber the best device to filter and clean the air of mold?

Yes, an air scrubber is the best device, effective for mold remediation.

Air scrubbers eliminate pollutants, including asbestos, chemical fumes, dust, pollen, lead, and others resulting from accidents or large-scale projects in the home.

These airborne contaminants pollute the indoor air by settling on carpets, upholstery, and furnishings, which will pollute the environment, thus the need for air cleaning protection.

Top Air Scrubbers for Mold

How Effectively Do Air Scrubbers Remove Mold?

An air scrubber can effectively remove mold spores from the indoor air with its HEPA filter and enough airflow. The HEPA filter traps and captures mold spores produced from the fungi in the indoor environment.  

The air scrubber works by drawing air from the compromised environment and filtering out impurities and pollutants such as mold by passing it through the HEPA filter. It is one of the most efficient methods of eliminating contaminants from the indoor air.

Mold spores are particulate matter with smaller sizes of 0.3 microns and below, which may easily pass through other filtration techniques except for a HEPA filter. A HEPA filter can efficiently trap these irritating small mold contaminants in the air.    

Air filters come with the MERV rating, and a true HEPA filter is MERV 17.

In the offices, using a HEPA air scrubber with germicidal Ultraviolet light prevents mold growth because the UV-C light is an air sanitizer that can prevent stagnant water in the air duct from turning to mold, thus maintaining good quality air.

Now, let us consider the critical factors you must look out for before purchasing the best scrubber for mold.

Buyer’s Guide To Select The Best Air Scrubber For Mold

When selecting a scrubber for mold, you must consider the features that will effectively capture the mold spores, stop the growth, and trap the odor caused by such pollutants.

1. Filtration System

The most effective air scrubber for mold must include a pre-filter, true HEPA filter, and carbon filter in the filtration system.

The pre-filter eliminates larger particles of air, leaving the smaller particles. The HEPA filter removes up to 99.97% of particles of sizes down to 0.3 microns. Since mold spores are these sizes, they cannot pass through the HEPA filter.

The HEPA-rated filters use anti-microbial treatment to stop the pollutant from reforming and protect the air. The activated carbon filters remove odor, volatile organic compounds (VOCs) and purify the air with chemical adsorption.

Purchasing an air scrubber with these filters will eliminate mold, remove odor and purify the air in your home, and replace it with fresh and clean air.

In this case, the XPOWER X-2580 HEPA Air Scrubber has the most effective filtration system with 4-stage filters to remove mold and odors due to water damage.

2. Airflow Rating

The airflow rating of an air scrubber is in CFM (Cubic feet per minute). With this, you will know how fast the scrubber can suck in contaminated air to release fresh, clean, and purified air.

Most negative air machines have a maximal airflow of 500 – 750 CFM, and you can adjust the airflow with the variable speed control switch.

The minimum airflow rating is 250 CFM, and there are several stages before you adjust it to 500 – 750 CFM. Some industrial air scrubbers come with an airflow rating of 1500 – 2000 CFM, and you may combine up to 3 scrubbers for a more powerful airflow if you are tacking mold in a larger space.

Be sure that you purchase a unit with a CFM rating suitable for tackling mold spores.

3. Power Outputs

Air scrubbers with 1/3 HP and 1/2 HP motors can power 200 and 350 Watts. The higher the wattage, the higher the airflow rating.   

For small jobs, you can use a single unit with 3Amps, but for bigger ones, you have to daisy-chain two or three units for a powerful airflow. That is why air scrubbers come with the GFCI sockets.

You can connect up to 3 units with the GFCI outlet to achieve 9 Amps. When you power ON the first unit, other units that link to it turns ON automatically for more airflow to remove mold from a larger space.

4. Maximum Coverage Area

Air scrubbers have the recommended maximum coverage area based on CADR ratings, ACH (Air Changes per Hour), and airflow rating. Units with a minimal coverage area of 500 sq ft and above are better. Anything below this may be too weak for mold remediation projects or renovation jobs.

5. Blower Type

Using this machine for mold will cause debris to accumulate on the filters, which may affect the speed and efficiency of the unit and lead to static resistance.

Although different blowers are available for air scrubbers, the best blower that overcomes a drop in pressure due to a dirty filter is the air-foil type blower.

With the air-foil type blower, debris cannot accumulate on the filters. Combining this blower with a powerful motor will produce enough airflow to sustain the filter.

The air scrubbers listed in this review come with powerful electric motors and an air-foil blower that removes mold effectively.   

6. Speed

There are two-speed options available on air scrubbers: single-speed and multiple-speed options. Devices with the single-speed option offer a weak air cleaning system since you cannot adjust their speed.

For the multiple-speed machine, you may adjust the speed for all projects. It provides a better cleaning system and circulates air better than the single-speed. Mold removal needs an air scrubber with a powerful blower and adjustable speed control settings.   

7. Durability

The rotomolded polyethylene body of an air scrubber can withstand different weather and handle for a long time without damage. Before making a purchase, ensure that you understand the details of operational faults and failures.

Also, confirm the maintenance of the unit and its warranty period. Always consider a brand with a track record of manufacturing high-quality products, and make sure it is up to the task required from it.

8. Price

We all know that quality comes at a price, but going for a robust high-end air scrubber with an outrageous price does not mean it will handle your project perfectly.

While you cannot choose price over quality, you can get your preferred unit with all the features you need for a particular project, even at a fair price.

Purchasing units with inferior specifications may lead to the inability to perform a specific task. It is best to consider the features you need in the device as this will determine the amount you spend for its purchase without overpaying for irrelevant features.
