List of Top 5 Air Scrubbers to Get rid of Dust

Important Factors to Consider to Select the Best Air Scrubber for Dust

1. Type of scrubber

Air scrubbers are categorized into wet, dry, and electrostatic. A wet scrubber will remove dust and other harmful substances from the air by letting the contaminated air pass through water found in the mechanism.

For better performance, other liquids of different chemical compositions are used to capture contaminants of diverse charges. The air coming out of the air scrubber will have more moisture.

In fact, one can see a cloud coming out of a wet scrubber. The wet scrubbers are more popular because they capture particulate particles and gaseous contaminants.

The dry air scrubber for dust is designed with a reaction center where dry reaction material or sorbent is found. The contaminated gases are passed through the sorbent, and pollutants are absorbed.

It is now becoming more common to use these air scrubbers whenever gases are contaminated with acid.

The third type of air scrubber is the electrostatic precipitators which use charged energy to eliminate dust. A metal plate charged with a particular charge is used to capture contaminants from the gases passing over it.

2. Range/ Room size

To get the best value for your money, you need to check CFM – Cubic Feet per Minute. This is the scrubber’s ability to remove contaminants from the air in a certain room.

For a large bedroom or a medium-sized bedroom of about 1500 cubic feet, you might not need a scrubber reading more than 500CFM.

Such a scrubber will only take 3 minutes (1500/500) to scrub the room once, assuming you have properly sealed the room.

Remember, a scrubber works in volume, which means that CFM takes the length multiplied by the width and height of a room. Some scrubbers have 2000CFM and more and are more appropriate for use in factories and large warehouses.

3. Capturing other contaminants

A good air scrubber should capture all the contaminants in the air. They’re popular among home remodelers and industrial workplaces because they make the environment healthy by removing all the dust, smoke, and other dangerous particles in the air.

In an industrial set up there are many contaminants besides dust. As such, you need a scrubber that captures the VOCs, smoke, and anything that can make the air the workers breathe unhygienic.

This is why some buy scrubbers equipped with UV-C light technology to ensure which destroys the captured contaminants.

As a homeowner, you might not need to go to great lengths as industries a home because the main contaminants are dust and smoke. However, when remodeling, you will need a scrubber that will eliminate mold.

4. Noise level

The air scrubber is noisy, but there is no need to run it overnight or throughout the day. You will find most air scrubbers producing <70 dba. This means you can’t have a quiet conversation around it.

However, depending on the intended use and power needed, you should consider how much noise the unit can make when in use.

5. Extra features

For improved effectiveness of an air scrubber, manufacturers do include extra features. Modern scrubbers have a pre-filter, main filter, and a blower at the bare minimum.

The carbon filter, which captures odors and gases, is a common feature in many modern scrubbers.

Some scrubbers come with UV-C light technology, designed to inactivate microorganisms such as mold, germs, and viruses. The UV light disrupts the pathogens’ DNA hence making them inert and harmless to people and animals.

6. Budget

The price of an air scrubber is something every other buyer will want to look at. In general, scrubbers are pricier than air purifiers.

This is because they are more heavy-duty and are only designed to be used in places and instances where intense cleansing of the air is required.

For the smaller scrubbers meant for smaller spaces like homes, the price will range between $500 and $1,000. The pricier scrubbers ($1,000 and above) are ideal for construction sites, commercial sites and industrial use.

7. Portability

Air scrubbers are often used to remove dust, mold, and other air contaminants from a space that has been contaminated. As such, they are not ideally designed to be portable.

Still, there is a need for portable air scrubbers that home remodelers and contractors can use. In a portable air scrubber, a series of HEPA filters are installed to ensure the air gets cleaned before it’s removed.

In an industrial setup where exhaust gases need to be scrubbed regularly, you will find permanently fixed air scrubbers. The portable ones are cheaper than the permanent industrial scrubbers.
