Best Air Scrubber for Drywall Dust [Top 5 Picks, Pros & Cons]

Best Air Scrubber for Drywall Dust

The air is contaminated with impurities that might affect your health if you continue to inhale them. Indoor air may contain more contaminants compared to outdoor air.

Air scrubbers remove these pollutants from the air. It is different from air purifiers because it deep cleans and eliminates harmful substances from the air, including airborne particles like drywall dust, pollen, pet dander, and mites.

It is necessary to improve the air quality in your surroundings, homes, industrial buildings, and workspaces.

Air scrubbers are machines or an HVAC unit that removes mold, pathogens, air contaminants, mites, and foul smells from the air using a multi-stage filtration system.

This portable negative air machine draws air into its compartment and traps the particles, then it passes the air through some filters and sends out clean, fresh air. They are more effective compared to other HVAC systems because their filters can:

  • Trap pollutants such as pet hair, dust, and smoke particles
  • Eliminate foul smell from the air
  • Kill pathogens with Ultraviolet light
  • Release charged oxidizers into the air to attract charged contaminants that can pass through the scrubber.

Now, let us take a look at the factors you must consider before buying the best air scrubber for drywall dust.

List Of Top 5 Air Scrubbers For Drywall Dust

Buyer’s Guide To Select The Best Air Scrubber For Drywall Dust

1. Filtration System

You have to consider the filtration system of an air scrubber because the clean and fresh air sent out by the device depends on the quality of filtration.

Most air scrubbers have two filters. The first one, known as the pre-filter, captures large particles like pet dander/fur and pathogens like mites.

The second filter is commonly called the High-Efficiency Particulate Air (HEPA) filter. It captures drywall dust particles and other smaller particles. It can eliminate up to 99.97% of small particles down to 0.3 microns and is very common in HVAC units.

Most scrubbers come with a three-stage filtration system to remove the tiniest particles and odor. The activated carbon filter is the third filter, which helps eliminate smoke from the air. It is called an odor control filter.

An air scrubber with a fourth-stage filter is the best bet. It filters gas fumes from the air. So, when selecting an air scrubber for drywall dust, always ensure that it has a high particle holding capacity with a low airflow loss.

2. Airflow Rating

Air scrubbers have an airflow rating between 100 Cubic Feet per Minute (CFM) to 20,000 CFM. The airflow rating determines the size of the scrubber. You need to consider your requirements for this device before making a purchase.

If you need it for your home, the one with an airflow rating of 500 or 550 CFM can handle it. For commercial and industrial purposes, a rating of 5,000 CFM and above will eliminate dust particles and drywall dust.

Construction workers should go for an air scrubber with a high airflow rating.

3. Air Blower Type

If dirt accumulates on the machine filters, its pressure will reduce. It is necessary to get a quality scrubber with a powerful blower to prevent dirt from building up on the filter.

Blowers functions in different ways. The airfoil blower in air scrubbers can overcome the pressure drop caused by dirty filters and enhance airflow.

The building up of contaminants on the filter may choke up the device and create a static resistance, which may incur maintenance costs in the long run.

It is pertinent to purchase an air scrubber with a more powerful blower for your jobs.

4. Price

The price of an air scrubber depends on the type of work and the location you are using it. It is wise to determine the features and sturdiness of the machine you need.

If you are tackling drywall dust, odors, and mold, then you don’t have to spend a fortune. The contaminant you are trying to get rid of will determine the amount you should spend on purchasing the negative air machine.  

Spending some amount on a 500 CFM air scrubber should be enough to tackle contaminants in your home, garage, and basement to give fresh and clean air.

The ALORAIR CleanShield HEPA 550 has a powerful blower with 3-stage filtration and is cheaper than other units in its category.

5. Durability

Since you will be using the air scrubber to tackle drywall dust commonly found at remodeling or construction sites, you must be sure that the machine has a durable construction that can withstand harsh conditions without breaking or cracking.

Well-tested brands with a history of making high-quality products will function just the way you want it and last longer, but remember that quality comes at a price, which you cannot compromise.

You can get a durable negative air machine at a reasonable price by choosing the one with your specific requirements.
