Without a shop air filtration system in your workshop, you could be spending a lot of time in a space with poor air quality. Dust, soot, and other airborne pollutants can infiltrate your respiratory system and make you sick (Source). The best shop air filtration systems ensure that the air in your workshop is clean.
A shop air filtration system, sometimes called an air purifier, is a device that sucks up air and rids it of contaminants using internal and external filters before circulating it back into the room (Source).
However, the best air filtration systems have a heavier airflow than a standard residential filtration system. Airflow is measured in cubic feet per minute (CFM) and is sometimes adjustable based on your needs.
Shop air filtration systems can be portable, however, industrial units are often hung from the ceiling for optimal results. They should be positioned near where you spend the most time and should be constantly operational.
Aside from occasionally having to change filters, shop air filtration systems require little maintenance and are easy to operate. Whether you’re a professional tradesman or a hobbyist, every workshop should have one.
Prior to purchasing a shop air filtration system, you’ll need to consider its air filter efficiency in microns. This number dictates the smallest particle it’s capable of trapping, so the smaller the better. You’ll also want to consider its airflow in CFM, its clean air delivery rate, and its size.
Don’t spend another minute in your workshop without one of these top-rated shop air filtration systems.
What is an Air Shop Filtration System?
An air filtration system is simply a solution that is primarily designed to purify the air in a shop setting. This is often achieved through a specialized filtering process to get rid of harmful microscopic particles from the air. However, different shop air filtration systems function differently.
For instance, a particulate filter consists of porous or fibrous materials that are meant to remove such solid particles as pollen, dust, bacteria, and mold from the air. Some of the best shop air filtration systems feature a catalyst or an absorbent material like charcoal.
Such systems are capable of removing gaseous pollutants like ozone and organic compounds from the air as well. Air filtration systems find their application in places where air quality is important, such as in ventilation systems.
How Much Does a Shop Air Filtration System Cost?
The cost of shop air filtration systems varies significantly from one model to another. The portable filtration models are the cheapest, ranging between $80 and $180 apiece.
For extended media filters, the cost including installation fees will be $400 to $600 per system. Electronic shop air filtration systems, on the other hand, are priced between $400 and $1,000 apiece.

Factors to Consider Before Buying a Shop Air Filtration System
If you would like to improve the quality of air in your shop, you should consider buying a good filtration system. Most of the modern filtration systems feature high-quality construction, powerful motors and an assortment of modern air filtration features. To choose the right system for your shop, here are some of the key considerations you need to make:
Type of Filter
Though designed to accomplish the same thing, the various residential and commercial air filtration systems are designed differently. Here are the three different types you should consider:
- Air Purifiers
An air purifier is essentially a device that suctions up small quantities of air and traps any contaminants using super-fine filters. The filtered air is then expelled from a chute into the room where the device is placed.
These systems are designed to do this repeatedly, continuously cleaning the air of a room. They are suited for small rooms as they can only purify a limited amount of air at a time.
- Industrial-Strength Air Filtration Systems
Though costly, these are some of the most effective air purifies in the industry. These tend to have larger capacities and most of them are designed for permanent installation in commercial and residential buildings.
- Ion Generators
These are portable shop air filtration systems. In their functioning, in generators are designed to produce minor ‘shocks’ into the air. This charges the airborne particles using static energy, which ate then attracted to nearby objects, such as walls, carpets, and furniture.
This means that you need to wipe every surface in the room thoroughly after using an ionic generator. However, there are newer models that are designed to attract the charged airborne particles to the filtration system itself.
Since they only have limited air filtration capacities, these air ionizers may only be used in a single room at a time.
How much air can the system clean per unit time? This is one of the important considerations you need to make in order to get a system if the right capacity for space you will be using it in. The airflow of a filtration system is expressed as the number of cubic feet of air it can filter per minute (CFM).
To arrive at the right CFM value, you should work out the changes per hour for the room ( length of the room x width x height x air changes per hour). Most rooms, including living rooms, offices, and bedrooms require about 6 air changes per hour.
Heavily polluted rooms like smoking rooms, restrooms and lobbies need about 12 to 15 changes per hour. Units with lower airflow ratings are suited for single rooms. If you need a model that will clean air for the entire home or larger shops, you should go for higher CFM values.
Air Filter efficiency
The efficiency of an air filter is expressed by the size of the smallest particles it can trap. For air purification systems, you should go for filters with an efficiency of 0.3 microns or less.
This is most air pollutants, including pollen, mold, pet dander, dust mites, and bacteria are between 0.3 to 5 microns large.
The best HEPA filters are very efficient at trapping airborne particle that is larger than 0.3 microns. To filter particles smaller than 0.3 microns, such as chemical fumes, cigarette smoke, and viruses, you should go for activated carbon filters, ultraviolet air purifies or an ionizer.
Clean Air Delivery Rate
The Clean Air Delivery Rate (CADR) is essentially the total volume of air that an air purification system can cleanse of a specific pollutant in one hour.
It is expressed in cubic feet per minute (CFM). The higher the CADR value, the more efficient a system is at removing that particular pollutant from the air.
The leading shop air filtration systems have a CADR rating of between 350 and 400 CPM.
How to Use a Shop Air Filtration System
Knowing which air purifier is best for your home is great, but is just the beginning. The best air purifier will have to be used properly for enhanced efficiency and durability. These tips will help you get the most benefit out of your shop air filtration system:
- Choosing the Location
Air filtration systems should be installed free of any obstruction. It is advisable to set the unit a few feet away from the nearest objects.
This is meant to offer free circulation air into and out of the system. Again, you need to ensure that the filtration system is of the right size, depending on the size of your shop.
- Proper Positioning
You also need to point the shop air filtration system in the right direction. If installed in a larger room, make sure the flow of clean air from your purifier is directed towards the occupants. When installing the unit in a smaller room, positioning may not be important as the air can circulate throughout the room with ease.
- Leave it Running
In woodworking shops, most of the routine tasks are known to produce sawdust that pollutes the air, despite having the greatest dust collection hoses. In such areas that re heavily contaminated, you may need to run the best shop air filtration system continually.
This is one of the reasons why a considerable number of modern filtration systems are energy efficient. This allows you to purify the air for long hours without hurting your electricity bills.
- Change Air Filters Regularly
Be sure to read and follow the manufacturer’s repair and maintenance instructions for the system. Generally, carbon air filters need to be replaced annually. Washable filters, on the other hand, should be cleaned after every ten days of use.
This will keep the unit functioning at optimal efficiency.
Our Final Verdict
Different shop air purifiers apply different purifying and cleaning technologies. Before choosing the best hanging shop air cleaner, you need to ascertain the main air quality problem you are trying to resolve.
Additionally, you need to get the ideal system depending on the size of the room.
Just as is the case with the five systems reviewed above, your preferred unit needs to have the right filter efficiency, airflow, and filtration technology for the intended application.
With this guide at your disposal, you should have an easy time choosing the best shop air filtration system.
