Reply 4 years ago. Curiously, both Powermatic models cleaned the air about 60 percent faster at their slowest speeds. In this mode the Mood Light which is also a status indicator will be solid blue.

In a workshop that uses cutting, grinding and sanding equipment, dust in the air is inevitable. This is most common in woodworking shops where large amounts of sawdust and woodchips are released into the air as we work. Shops that deal with stone have a bigger problem because many stone products release minute particles that contain crystalline silicone and the health effects from inhaling silicates is particularly dangerous.

This is also true for contractors who cut masonry and stone on site. The main effects of dust or sawdust in the air is that they cause damage to the respiratory system, resulting from particles collecting in the lungs.

Breathing in any amount of dust over a prolonged period can cause irreparable damage to your lungs. Other health problems can be scratching of the eyes and, in some cases, skin irritation. Most woodworking shops will use dust extraction systems that are connected to the machine — usually dust collection bags attached to a vacuum system. These systems are very effective and remove a lot of the wood-chips and sawdust released by the tools that we use.

However, there is always dust that is not collected by a conventional dust extraction system. Small particles of 5-micron or less become airborne very Workshop Air Filter System 10 easily and these particles are the most dangerous — causing the most damage to our lungs. They are too small to see and will go by unnoticed unless they are in large volumes. This causes a fine mist in the air. Because most of the fine dust is not collected by regular dust extraction systems, a secondary air filtration system is of great importance.

Not only are particles in the air a cause of health problems, but they can also have a negative effect when applying finishes and paint to the final product. In the US, indoor air quality regulations are a legal requirement for employers in two states — New Jersey and California.

Despite the lack of federal legislation for air quality in the workplace, labor law does state that all workers have the right to a safe and healthy working environment. By default, this means that if the air in the workplace poses a health risk to your employees, you are in contravention of the law — no matter what the state laws are.

This is why any workshop that produces dust needs an air filtration system that is capable of removing dangerous particles from the air. This means that it needs to have the correct filters, normally removing particles of up to 1-micron in size. To give you an idea of what this is, 1 micron is 0. For most shops, a 1-micron filtration system is fine for solid matter particles.

An HEPA filtration system will remove particles of 0. Your workshop air filtration system needs to clean the air in the shop times per hour. This means that the entire volume air in the area needs to pass through the air filtration system at least six times every hour. An air filtration system uses a fan to draw air through the filters and release it back into the atmosphere as clean air without any harmful particles.

To do this you need to calculate the volume of your shop Length X Width X Height , you then multiply this by the number of times you want the air to be cleaned and divide your final answer by Installing an air filtration system is not complicated.

Larger units may require a V circuit and may also require heavier mountings as these will be heavier machines. Generally, people prefer to hang the air filtration system from the ceiling and most of the smaller models have eyes or hooks to make this easy to do.

Placing the filtration system too close to a wall or workbench will obstruct the airflow. This will provide the best air circulation around the room. Maintenance of your air filters is critical to ensure that the system works properly. Air filtration systems have filters that are designed for cleaning and are usually very accessible and easy to remove and replace. This can be done by using compressed air or a vacuum cleaner. You should check these filters to see how often they need cleaning, maybe with every third work session.

A filter can be cleaned many times, but at some point, they need to be replaced. Generally, the larger the unit, the higher the airflow. None were loud enough to require hearing protection. With each unit, airflow dropped off as dust built up in the filters—especially the prefilter—but three Shop Fox, Supermax , and Powermatic PM fell off less than 10 percent.

The box fan dropped off the most, eventually stabilizing at 30 percent, followed by the Rikon 28 percent and Powermatic PM 23 percent. We tested these systems in an cubic-foot shop space walled off with plastic floor to ceiling. Then we sanded MDF with a drum sander using grit sandpaper, and no dust collection.

The chart above shows how well each machine filtered dust in our trials. Both Jet units scrubbed the air in 13 minutes at high speed. Curiously, both Powermatic models cleaned the air about 60 percent faster at their slowest speeds. The good news: Each machine was able to return the air to the control level. Obviously, the Best Small Workshop Air Filter 40 larger the shop space, the more time each machine will Air Filter For Small Workshop Query likely need to clean the air. All the rectangular-box machines have a prefilter and secondary pocket filter.

Both are easily accessible for cleaning. Eight of nine tested air-filtration systems have two sets of filters, as shown above. The prefilter, made of spun nylon or pleated fabric, captures larger dust particles 5 microns or larger , and can be cleaned with compressed air or a shop vacuum. Most prefilters will eventually need to be replaced after cleaning no longer improves their performance.

The Powermatic PM, below , has a screen rather than a traditional prefilter. Because replacements for these filters cost 4—5 times more than the prefilters, be sure to keep the prefilter clean or replace it often to preserve the inner filter. As dust particles build up on the filters, airflow drops off, but filtration improves.

Bottom line, most "dust collection" is really "chip collection" and a portion sometimes a large portion of ultra fine dust never enters the airstream heading to that state-of-the-art dust collector. A 4-inch diameter pipe has a cross-sectional dimension of 0. To achieve the "holy grail" of CFM of airflow, the dust collector will need to generate an airstream moving at 5, feet per minute 5, FPM will actually produce a theoretical CFM of It is simply not possible for a 5, FPM airstream to overcome inertia, slow down, and capture a particle of dust moving at over 9, FPM.

Of course, some particles will be caught. Larger, heavier particles will not move as fast and air resistance and gravity will slow those particles more quickly. The airflow produced by the "dust collector" can grab and gobble them up. A guard over the top of the spinning blade helps. Dust hits the blade guard and bounces, slows, and the airflow can capture more… but still not all… some will escape and float about, unimpeded, in your shop.

I have a large cyclone dust collector. The filter efficiency is high, the airflow outstanding. Even with all of that, and as clean as my shop always appears, you can wipe a finger along any wall and come up with dust… a lot of dust, unfortunately. In my dust collection webinar class I encourage woodworkers to set their expectations realistically and approach dust collection as a "holistic" endeavor, with a focus on "point-of-capture" strategies, PPE, and supplemental air cleaners.

A dust collector, no matter how good, simply won't do it all. Please, please, please, don't mistake my heretical opinion of dust collection as an excuse to "give up" or to think that "any old dust collector" will do, or worse, do without. A good dust collector will collect larger chips and sawdust and will make woodworking machines run better, make the work environment nicer, will result in better outcomes, and will go a long ways toward cleaning up the air.

A good dust collection system is absolutely essential, but understand, what we euphemistically call "dust collectors" are really just "chip collectors. A secondary shop air filter will get a lot of that free-floating dust, but it will not get it all, either.

To really clean the air in your shop, you need a tertiary air cleaner… one expressly made to "clean" the air, not just filter it. Big noisy units and small noisy units. Round units, square ones, tall skinny ones, odd-shaped ones, and even a few high-tech futuristic-looking ones.

They all captured dust, as was obvious when it came time to change or clean the filter. But none worked as well as I had hoped and all had shortcomings. Most were way too noisy, the units were what I consider to be "consumer grade" translated, that means "cheaply made" — they certainly weren't cheap to buy!

And they all eventually broke down or became ineffective. It was disappointing and I began to feel that no one made a really decent air cleaner.

The core problem was that I was looking at air filters, not air cleaners. Then I happened to visit a few cigar bars. Cigar smoking always seemed so convivial, and well, cool. And it seemed to me that cigar smoking goes naturally with other good things… a glass of wine or a single malt scotch, good conversation, perhaps a game of cards… but for some reason, even though I love those other things, I don't love cigars.

It is not for a lack of trying. I've tried expensive cigars, really expensive cigars, and cheap cigars. Long ones, fat ones, thin ones, mild and strong, dark and light, domestic and foreign, some that were probably even illegal to own… I just can't seem to develop a taste for the things… but I tried.

Along the way I visited a number of really swank, high-end cigar bars. It was at these better cigar bars that I started to notice a commonality besides the ambience and fellowship. A certain type of air purifier seemed to be the de facto "standard. The cigar story is simply a way to provide backdrop for a recent "wood shop experience. By the way, isn't "nose blind" one of the greatest commercial tag lines ever? I tried to sort out the aroma. There was a smell of wood, of course… several varieties, in fact.

But there was more. Some lingering fumes of finishes still curing… a little mold smell, an entirely different story… a scented trash bag that smells worse than the trash… residual smell from the last batch of coffee beans I roasted… the space-age oil I spray on top of my cast iron tools to prevent rust… probably more… all intermingled into one really unpleasant odor. My thought process was straightforward… if one of those things could clear the air of cigar smoke, surely it could clear the air in my shop.

I equate almost any expenditure to what an equivalent amount of money would buy in new tools. Still, I had to give fair consideration to my health and overall comfort as well. You see, I have allergies.
