According to recent statistics, 85-percent of lung cancer is caused by smoking.
Well, what about the other 15-percent?
Surprisingly, the rest of it, to a large degree, is caused by inhaling carcinogenic particles. We don’t mean to scare you but this is a fact worth considering.
Working in a woodshop by default creates a large amount of wood dust, which contains various harmful chemicals. And by using a dust collector you may get rid of the larger bits of residue but the atmosphere can still contain particles as small as a single micron (0.001-millimeter).
So, what do you do?
You get a filtration system that can purify your workspace’s air to a degree of at least 80 to 95-percent, ensuring your lungs are safe even from the specks of wood dust that can’t be seen.
Which is why we’ve decided to create this guide to help you choose the best woodshop air filtration system out of a zillion mediocre options available in the market.
Our goal is to ensure the maximum amount of protection for your health without compromising the efficacy and flow of your work.
Benefits Of Using Woodshop Air Filtration System
Keeps Your Lungs Healthy
As a professional carpenter or a DIY enthusiast, an unavoidable issue is dealing with wood dusts. Specifically, artificial wood can contain a number of chemicals that cause severe damage to your lungs and nasal passage.
Inhaling wood dust has been connected to a number of diseases, such as Dermatitis, Asthma, various allergies, and Cancer. However, simply keeping a dust collector in your workshop won’t provide sufficient protection against such serious consequences.
Air Filtration systems designed to be used in woodshops, can purify the air by catching particles as tiny as 0.001-millimeter. A dust collector isn’t able to capture particles of this size. Thus, without using an air filter you may expose yourself to life-threatening specks of wood too tiny to be captured by other purification systems.
Cleans Your Workshop Even When You’re Not Around
Majority of the air filters have an adjustable timer built into them. The purpose is to allow the system to shut itself down after a certain period of time that can be pre-programmed by you.
This way you can, for example, set the timer at a 2-hour period and leave the workshop. The filter will purify your workspace’s air for 2 hours then automatically turn itself off. As a result, aside from saving a chunk on electricity bills, you also get to come to your workshop the next day, already cleaned and ready for use.
Offers Easy Installation, Simple Operating And Low Maintenance
Air filters are quite easy to install. They come preassembled, you simply have to decide where you’ll hang/set the device.
They also have a fairly simple operating mechanism, which doesn’t require much time to learn. And, in terms of maintenance, other than a few occasional filter replacement and weekly cleaning, the system doesn’t require much attention.

How To Choose The Right Woodshop Air Filtration System
The area coverage speed of a woodshop air filter is measured in CFM.
CFM (which is an abbreviation for “cubic feet per minute”) describes how many cubic feet of space the purifier can clean in 1 minute. The higher the CFM rating the bigger space a filter can purify per minute.
If you operate from a garage/home style workshop, a filter with a range of 300 to 450 CFM should be enough for effective purification. However, if you want to install a filter for an industrial workshop (e.g. an area with a 90 to 140-square meter space or more) you should buy a filter with a range of 1000 to 1700 CFM.
You can check the product’s description segment to figure out how much area the device can cover, how many purification cycles it can run per hour, and the range of CFM it offers. This will give you a general idea about the filter’s purification capability and help you decide the optimum CFM range for your needs.
Filtration system of an air filter is, without a doubt, one of the prime factors to look into.
The standard is using a 5-micron external filter with a 1-micron internal filter to ensure a 80 to 95-percent air purification. However, there are a few additional factors that we think are worth checking out.
For example, you should opt for an electrostatic outer filter as it is capable of attracting more particles through electronic charges. Also, choose an internal filter with multiple pockets, which minimizes the need to clean it on a regular basis.
The best woodshop air filtration system should have a diffuser and a movable exhaust as well. The diffuser will help to disperse the purified air over a wider space and a movable exhaust will let you direct the airflow to your preferred direction.
The filtration system of an air filter is certainly an important factor, but don’t let that distract you from the mechanism that allows the filters to function in the first place, the motor.
We recommend a minimum of 1/3 to 1/5 HP motor for small and medium sized woodshops. Motors with this range of horsepower can function safely with a 15-amp circuit breaker, which is the standard for most home electronics system.
For an industrial workshop, you should choose a minimum of 1/6 to 1/8 HP motor.
Also, make sure to choose a filter that provides a motor with an overload protection. Otherwise, an absence of this seemingly minor feature can cause potential fire/explosion hazards in your workspace.
Another factor to consider about the motor is its RPM. RPM (short for “revolutions per minute”) describes how fast the motor can spin the blower wheel/fan. The fan is responsible for sucking the polluted air inside the device through the filters and then pushing out the purified output. Thus, a motor with a high RPM means faster airflow.
We recommend choosing a filter that offers a range of RPM (e.g. a motor with 1200, 1400 and 1700 RPM) for you to choose from. This way you can adjust the speed of the airflow in accordance with the demand of the situation.
Generally, woodshops are situated in marketplaces or a residential area rather than in an industrial sector. Therefore, a loud air filter can become a cause for concern.
Specifically, if you work from home then a loud filter may cause a bit of domestic irritation and neighbor complaints. It’ll also prevent you to keep the device on at nighttime.
So, for home workshops, we recommend choosing a filter with a maximum noise level of 25 to 35-dB. For a marketplace woodshop, you can get away with a noise level of 40 to 60-dB.
However, for industrial use, you may need to go up to 70-dB as industrial filters generate a massive amount (up to 1700 CFM) and speed (up to 1700 RPM) of airflow.
Arrangement And Portability
If you intend to set the filter at your ceiling, then make sure it comes with sturdy eyebolts or mounting hooks on the top surface. Some manufacturers include chains in the package as well, so you won’t need to buy them separately.
The popular method is to hang the filter from the center of the ceiling, as this placement usually ensures the most optimum level of circulation. Some people prefer to set the filter by using a bolted metal frame instead of hanging, presumably to have a more secure setting.
If you intend to travel with the filter, make sure it has an ergonomic and padded carrying handle which is strong enough to carry the load of the device. For using it on your workbench/table, we recommend getting a filter with padded feet to avoid scratches on your work surface.
Construction Of The Cage And Air Vent
Most manufacturers use a squirrel cage to case the filter. We recommend choosing a filter that uses an industry-grade metal cage with a steel net protected air vent.
Go for an air filter that has a board for manual control, along with a remote to allow a wireless operation. This way you won’t have trouble operating the device whether it’s hanging from the ceiling or sitting on your worktable.
Lastly, be sure to check that the filter has features like time delay and auto-shutdown. These features will help to keep your workstation clean and breathable even when you’re not physically present there, along with reducing a significant amount of cost on electricity bills.
Frequently Asked Questions
What’s The Difference Between A Dust Collector And An Air Filter?
Answer: A dust collector is typically used in an industrial setting but they can be an important safety accessory in a personal workshop as well. However, it is designed to collect larger particles, directly from the source, thereby, leaving the air still impure with smaller particles (e.g. 0.005 to 0.001-millimeter particles).
An air filter is better equipped to refine the air of these smaller particles. Thus, using an air filter along with a dust collector can provide you foolproof protection against pollution.
What Is The Difference Between CFM And RPM?
Answer: CFM (short for “cubic feet per minute”) determines how many cubic feet of space the purifier can clean under 1 minute. The higher the CFM rating the bigger space a filter can purify per minute.
RPM (short for “revolutions per minute”) describes how fast the motor can spin the blower wheel or fan, which sucks the polluted air inside the device through the filters and then pushes out the purified output.
By knowing the CFM and RPM rating of an air filter, you can precisely determine its efficacy and decide if the device meets your expected requirement.
What Size Air Filter Should I Get?
Answer: Air filters come in a diverse range of diameters. Some are taller but thin, while some are shorter but wide. However, the depth of the filters stays more or less the same ranging from 10 to 20-inches.
The shape and size of the filter also largely depends on its CFM and RPM rating. Industrial air filters with high CFM (up to 1700 or more) and high RPM (up to 1700 or more) naturally take up more space, along with being heavier than filters designed for personal woodshops.
According to most woodshop air filtration system reviews, assessing features like the diameter of your workspace, type of your shop, the number of particles required to be purified per minute, etc. can help you determine the perfect size.
How Do I Clean My Air Filter?
Answer: Air filters are fairly easy to clean and maintain. You can wash most 5-micron external filters and use a blow drier to clean 1-micron internal filters once a week to keep the filter running at an optimum level.
However, after a while, you may need to consider replacing the filters if they become too clogged up despite a normal, regular wash. Most manufacturers offer replacement filters for their products that you can buy separately.
Is It Better To Hang The Filter Or Place It On My Workbench?
Answer: That is entirely a matter of preference.
If you want an equal circulation all over your workspace then it is better to set the filter at the center of your ceiling (however, the shape of the room also needs to be considered in this case).
On the other hand, if you want the filter to flow purified air in a particular direction, or close to the tools you’re working with, placing it on your workbench would be a better choice. However, in that case, make sure the filter has padded feet to avoid scratches and stains on your worktable.
“The greatest trick the Devil ever pulled was convincing the world he didn’t exist”
This famous quote is apt to describe why you need an air filtration system. Because, they can save you from particles which are too tiny to see yet capable of causing massive damage to your health.
However, if you choose an air filter that can’t do its job properly, then you’ll be back in the same situation.
In this guide, we’ve tried to provide the facts you need to know for buying the best woodshop air filtration system in the market, while avoiding the ones that fail to deliver what they promise.
So, stay happy, stay healthy, and choose your filters carefully!
