Woodworking is truly wonderful: shaping and manipulating a piece of wood until it assumes the form of furniture, tools, and even showpieces—all with a few tools and the right skills.
But it’s also messy and even dangerous. Part of the reason is sawdust. In any woodshop where sanding, grinding, and cutting occurs, there is bound to be sawdust. And without the best woodshop air filtration system, you might end up inhaling this dust, which contains harmful chemicals and even carcinogens.
“But what about my dust collector?” you might be wondering. Those can only hold larger wood chips but not smaller, finer particles that remain in the air.
So here are the best filtration systems currently to be found on the market, reviewed for your benefit.

Buying Guide for Woodshop Air Filtration System
Before you decide which air filtration system to buy, make sure to keep the following factors in mind.
The strength of an air purifier or filtration system is determined by the amount of air volume it can move. This is measured in cubic feet of air moved per minute (shortened to CFM). Choosing a system with the right CFM involves making some calculations.
Use this formula: first, multiply the length of the room with the width of the room. Then multiply this figure with the height of the room and the number of air changes per hour.
But what what does "air changes" mean? It simply refers to the number of times you want your air filtration system to put out fresh air into the workshop. Rooms with heavy pollution require about 12 to 15 air changes in a single hour, but if you don't do any heavy woodworking, as low as 6 air changes per hour also work.
Another indicator of the strength of the air filtration system is its filters. Most systems have external filters which can capture particles measuring 1 to 5 microns. These ensure air purification of 80 to 95 percent.
As before, the right number of filters depends on the size of your workshop, how frequently you work there, and the scale of your projects.
Look into the specifics of the filtration system as well. Some air filtration systems are equipped with inner filters as well as external ones, which allows for better quality air. Whichever you choose, though, steer clear of single-filter models since they can't catch large particles and are prone to clogging.
The versatility of your air filtration system is determined to a great extent by its available fan speeds. The larger your workshop, the higher the fan speed should be. And as you may be able to imagine, the CFM of the machine ties closely in with speed. Also, look for models that allow you to adjust the fan speed.
The best air filtration systems are those that are designed for long-term ease of use. On that note, we prefer systems with a diffuser, which spread clean air more easily. A movable exhaust is also preferred as this allows you to control the direction of the airflow.
Like any machine, the air filtration systems also come with their own motor. Motors having at least 1/3 to 1/5 HP are suggested for small to medium workshops. If you're working in an industrial woodshop, however, a minimum of 1/6 to 1/8 HP is the better choice.
RPM is also an important consideration when it comes to the motor. An air filtration system's RPM determines the speed at which the motor spins the fans. So, a higher RPM translates to a faster airflow and cleaner air delivered to you quicker.
Also, make sure that the filtration system you choose is equipped with overload protection. This eliminates the risk of a fire hazard.
FAQs About Woodshop Air Filtration System
Q: What is an air filtration system?
Ans: It's a technology that prevents dangerous particles from persisting in the air of your woodshop. It works with the help of air filters.
Q: What happens if you inhale wood dust?
Ans: Not to scare you, but wood dust inhalation is associated with quite a few diseases, such as asthma, dermatitis, and even cancer.
Q: Can't I just use a Shop Vac instead of installing an air filtration system?
Ans: Shop vacs undoubtedly offer great suction; however, their airflow is also quite weak. Moreover, whereas an air filtration system can work in the background, a vacuum can only be used after you're done.
Q: Doesn't my dust collector do the same job as an air filtration system?
Ans: A dust collector can only catch the particles which happen to fall in its direction. An air filtration system works constantly in the background to keep the air in your workshop clean and can deal with small, unseen particles.
Q: How should I clean my air filtration system?
Ans: Take out the filters, dust them off, and clean them in water. Then let them dry before reinserting.
Q: Where should I install my air filtration system?
It’s common to hang it from the ceiling, but wherever you put it, make sure that the air intake outlet isn’t obstructed.
While it's true that all of the products mentioned above will provide top-notch filtering, making a choice ultimately depends on you. The fan speed and airflow should be adjusted to how frequently you work. This will allow you to get the best woodshop air filtration system without spending unnecessarily on high-powered models.
We ardently hope this review has aided you in choosing the right filtration device for your workshop.
