Best Air Scrubber for Smoke [Top 5 Air Scrubbers, Comparison]

Best Air Scrubber for Smoke

Air scrubbers are known for maintaining clean and purified indoor air, the reason they are suitable for offices, homes, and construction sites. Standard air scrubbers come with a blower that channels contaminated air through a series of filters in the machine.

Each filter eliminates various pollutants, such as smoke, dust, pollen, odor, and more, from the air. The filters also trap airborne contaminants of various sizes measured in microns (a millionth of a meter).

Although the sizes of these smoke particles range from 0.008 to 0.6 microns, air scrubbers are still very effective against them. Air scrubbers eliminate smoke particles from the air through active and passive methods.

In the active method, the machine cleans the air by generating and spreading negative ions throughout the scrubbing area to bond with pollutants, such as smoke and dust. When this occurs, the particles become too heavy to float in the air as they fall on surfaces and floors.

Then you can remove those particles by wiping the surfaces. With the negative ions, filters can trap particles that are too small to catch.

At the same time, the filters in the machine, such as the pre-filter, HEPA filter, and an activated carbon filter, combine to eliminate smoke from the air passively.

Top 5 Air Scrubbers for Smoke

Buyer Guide To Select The Best Air Scrubber For Smoke

If you want to get rid of smoke and fumes from the air, there are certain features you must consider in an air scrubber before making a purchase. This buyer guide will help you select the best air scrubber for smoke.

1. Filtration System

Some air scrubbers remove smoke from the air by leveraging various features simultaneously. They combine the functions of negative ions, HEPA filters, and activated carbon filters to remove smoke particles, fumes, and odors.

The best air scrubber for smoke must come with a pre-filter, HEPA filter, and an activated carbon filter.

The pre-filter captures large particles, which are too heavy to float in the air after bonding with the negative ions released by the negative air machine.

HEPA filters are effective at trapping particles of sizes down to 0.3 microns. With this, they will do an excellent job trapping more smoke particles and further reducing the smoky air.

The negative ions and HEPA filters reduce the volume of smoke particles, but they are not good at neutralizing the smell of smoke from the air. That is the essence of having the activated carbon filter in your air scrubber.   

The activated carbon or charcoal filters eliminate the smell of smoke and other odors from the air. Not all air scrubbers come with these carbon filters, but some are compatible as optional filters.

Using the machine for a long time to rid the air of smoke will cause the filters to become saturated. That is why it is vital to replace the filters periodically so that the scrubber can maximize its efficiency.  

2. Airflow Rating

The Cubic feet per minute (CFM) rating of an air scrubber gives information on the volume of air cleared by the unit per minute. It is also called the airflow rating and falls between 100 CFM and 20,000 CFM.  

If you intend to use an air scrubber in your home for smoke particles, then an airflow rating of 500CFM and above is sufficient. For industrial or commercial purposes, a rating of 5,000 CFM and above can eliminate smoke from the air in your environment.

You must have in mind that the rating determines the size of the machine, so the higher the airflow, the larger the air scrubber. Due to this, it is necessary to decide on the location you want to use the machine before purchasing.

3. Blower Type  

The type of blower used in an air scrubber is vital as dirt filtered from smoky air accumulates on the filters and causes a decrease in pressure. A powerful blower such as the airfoil type prevents specks of dirt from building up on the filter.

When contaminants build up on the filters, it may choke the machine to create a static resistance, which incurs maintenance costs in the long run. This blower type enhances airflow by overcoming the drop in pressure caused by dirty filters.    

4. Coverage

The maximum coverage area of an air scrubber derives from ACH (Air Changes per Hour), CADR rating, and Airflow rating. If these factors are higher in a particular machine, the coverage area of that machine will be higher.

For smoke removal from small spaces, a minimum coverage area of 500 sq ft is preferable. To eliminate smoke from large areas, you can daisy-chain up to 3 units using the GFCI outlet on the primary unit. 

5. Air Changes per Hour (ACH)

ACH is the number of times the volume of air filters in 1 hour. It means that a unit with an ACH of 4 will draw in and decontaminate the air in a room about 4-times in one hour.

Experts recommend that air scrubbers for smoke in homes or small offices should have at least 6 ACH, which means completing air changes once every 10 minutes.   

For heavy contaminations caused by smoke particles during industrial projects, a scrubber with an ACH of 10 is the most effective in cleaning the air.

6. Durability

Any machine you purchase for your project must stand the test of time and prove its durability to avoid wasting money from time to time buying new units.

The best air scrubber for smoke must have a durable construction with a rotomolded body that can withstand harsh conditions like the heat from smoke and fumes.

Go for brands with positive feedbacks from buyers and a history of manufacturing quality machines, but remember that you cannot compromise quality over price.

You can also get a reliable, portable, and durable unit at a better price when you go for the one with your specific needs.    

7. Price

The type of work you intend to do with the machine determines the amount you should spend to purchase it. Always ensure that you specify the features of the unit you need to avoid spending too much on unnecessary features.

If you are tackling smoke, fumes, and smoke smell in your home, then a moderate-priced air scrubber can do the job.

Spending a few hundred dollars on a scrubber with an airflow rating of 500CFM and above should be enough to remove smoke particles from the air for fresh, clean, and purified air.

Final Words:

The tiny particles of smoke can penetrate your lungs and cause heart and asthma attacks, bronchitis, strokes, and respiratory diseases.    

Inhaling these fine particles of smoke may lead to premature deaths among people with lung and heart diseases. Children can experience dizziness, chest pain, coughing, wheezing, and breathing difficulty.

However, using an air scrubber for air contaminated with smoke removes the fumes, smoke, and odor, to maintain clean, fresh, and purified air. Also, it will help with allergy symptoms, coughs, sinuses, fatigue, nausea, dizziness, and headaches.
