The shop vac is one of the most valuable cleaning tools in your home. It helps to take care of various messes, including fluids on your floors that several other vacuums wouldn't pick up. However, its difference from the traditional vacuum for carpets is why you need to take a few minutes to learn a few things about this type of vacuum before getting a shop vac or putting yours to work.
One of the most commonly asked questions that pop up in people's minds is, "can you use a shop vac without a filter?"
Well, your shop vac can be used without a filter. There are situations where you may prefer to do without a filter. The filter on the vacuum helps while sucking up dry dust, but you also need to know that it's not all the time the filter is required.
To better understand these impressive cleaners, we would discuss how they function and answer some common questions concerning their usage.
Will it hurt a shop vac without a filter?
Even though you can use the shop vac without a filter, it's, however, safer not to take it out. This way, your wet dry vacuum is more versatile, and the risk of getting damaged is reduced. Also, not all models of shop vacs can function well without a filter. Depending on the structure and model, there can be a risk of damaging or breaking your cleaning tool.
You may use a shop vac without a filter while cleaning an open space. But if you must clean an enclosed space and avoid cases where the wet dry vac blows dust back into the air, cleaning with a filter is installed. Hence, the purpose of vacuuming is defiled. The filter helps avoid lots of trouble and debris blowing right back into the air around you, especially while vacuuming dirt and dry surfaces.
This would equally mean that you can use a shop vac wet dry without a filter when cleaning moist dirt or fluids. Otherwise, you are putting your machine at the risk of getting blocked and will stop
functioning. Also, if you use a dust bag, you should remember to take it out when cleaning wet surfaces. It's essential to bear in mind that not all shop vacs function well without a filter. So it would be best if you did enough research on your model to ensure it can keep up without one.
Water from the bottom of the tank can catch the dust you are sucking up and leave some behind. A shop vac that uses water as a filter system can also do without the filter. But it's still not a recommended practice since it can shorten the lifespan of your machine.
What does a filter do in a shop vac?
While answering the question on "can you use a shop vac without a filter?" it's crucial we describe what a filter does in a shop vac.
The design of the wet dry vac is to ensure that it sucks up almost anything. It's a highly versatile and powerful machine suitable for all kinds of vacuuming work. The shop vac filter is a crucial component that even most people aren't aware of its use or even its existence. But it serves a greater purpose than you may think.
The filter captures small particles that can infiltrate the air we breathe, causing allergies, dirty messes, or eventually damaging your wet dry vac. However, you need to ensure your shop vac uses quality filters that capture all the finest and most dangerous dust. Dust is most harmful when they are challenging to see with bare eyes. These types have more ability to affect the performance of your machine.
However, while some vacuums come with filters, some may not. But a quality filter will prevent harmful fine dust from getting into your workspace. Regardless, it would be best only to use a shop vac without a filter when cleaning wet debris. Even though some models have filters built especially for wet cleaning, you can only use them while dealing with a small amount of water. In this case, you shouldn't forget to rinse and dry it after.
Ensure you are using the appropriate accessory for the specific types of cleaning. Depending on the shop vac model, the filters may look different. Regardless, it should be able to remove water.
A foam sleeve filter is an excellent choice to use while vacuuming dirt from wet surfaces like swimming pool areas. It helps to keep dirt away from entering the motor. Dry cleaning, on the other hand, can work with a wide range of filters. Some are pretty basic while picking up big pieces of wood chops and smaller stones. The more advanced ones are suitable for gravel, sawdust, and other similar things. A more acceptable filtration system can handle powder, ashes, and even if the dust is too fine.
Also, make sure you use filters that are compatible with the model of your shop vac. But when you notice a loss in suction, this can be an indication to change your filter.
Do I need a filter in my shop vac if I use a bag?
Most shop vacs have two stages of picking up debris. This means the wet-dry vacuum intends to use both the canister filter and bag filter. With or without a bag installed in your shop vac, you should still use the filter. The bag gets most stuff, but the filter helps protect against any item that gets through or in case of bag failure.
The filter plays an important role, especially when working on drywall dust with fine and potentially hazardous dirt. Using both may not be compulsory, but it keeps the inside of the shop vac cleaner and helps the filter last longer. If you have to pick up a bunch of garbage mixed with water, it's essential to use both.
The bag saves you so much stress, prevents clogs, and avoids messing up your canister. It makes emptying the vac easy, while the filter gets the dust out of the air. It's wise to have both. After which, it's right for you to dispose of the bags. If the bag rips open and you don't have a filter, the dust would end up thrown out through the exhaust port. This way, the dirt you suck up gets into the fan and motor, resulting in your shop vac shutting off and requiring repairs.
While the bag acts as a collector to avoid blasting dust all over the place, the filter helps when the bag ruptures. Picking up large to medium-sized debris may not necessarily require you to use a collection bag. However, if you are picking fine dust such as drywall or plaster, you can even use a HEPA filter along with the collection bag.
How often should you change the shop vac filter?
Putting the shop vacuums through several cleaning tasks can get them less efficient and effective than they should be. Some parts, such as the filter, can have shortened useful life. A clogged-up filter will end up overworking the shop vacuum motor, and if it continues, the motor can burn out. Replacing a burned-out motor can cause a lot of money.
Vacuum filters are necessary parts of shop vacs that capture dirt and ensure it doesn't return to the air. It's better to ensure you don't ignore your vacuum filter. When you notice a tear, rip, or stuck on the stain from paint or other debris, it's important to consider replacing your filter. Particles like dust that escapes the filter can clog your unit and cause your machine to lose suction.
The proper recommendation from manufacturers is to change your filter averagely every three to six months. However, a lot also depends on what you regularly vacuum. Fine dust and pet air can clog your filter much faster than regular dirt or dust, so you may even change it earlier than the recommended time.
Also, if you or your household suffer from allergies, it's essential to change your filter more often. New filters will prolong your vacuum's life and ensure optimal performance by keeping dirt and obstructions away from critical mechanical parts.
How often should I clean my vacuum filter?
While some wet dry vacuum cleaners come with washable filters that can be rinsed off and reused over and over again, some don't. Pleated filters that are not washable should be replaced at least twice a year. However, it's often common to see people neglect cleaning their vacuum filters. Most time, it could be due to having limited time, or we don't just think about it.
Even an averagely dirty filter can cause significant effects on the suction power of your shop vacuum. Ideally, you need to clean your vacuum filter every three months or even more often if you use your vacuum regularly or for high-traffic areas in your home.
The most effort by most people is only by taking the filter out of the shop vac and tapping it inside trash to knock off the dust. Unfortunately, this is not an effective way to clean your vacuum filter.
For your shop vac to run at its best capacity and have a longer life, you should empty the tank after collecting dirt and give the filter a thorough cleaning.
It will help if you take your vacuum to your garage or a place in your home where you do not mind getting dirty. Grab the shop vac and gently clean the pre-filter screens and post-filter screens with clean water from your kitchen sink or sprayer on your hose. But, be gentle with the nozzle, and ensure the water pressure does not damage the special coating on the filter.
After cleaning the filter, ensure that they are completely dry before returning them to your shop vac. Also, do not machine wash or dry the filter.
What happens if I don't clean my vacuum filter?
The vacuum creates suction, buy pulling air into itself. While absorbing air, it also draws in dust, dirt, and other debris mixed with everything coming from the floor. Meanwhile, the more significant bits fall directly into the canister of the bag. The fine dust particles remain suspended in the pressure created by the air. And since these particles are so small, gravity barely affects them.
The dirty air cannot permanently stay in the vacuum cleaner. It must leave somehow. Now, this is where your filter comes in. The filter allows only air to flow while catching the dust and dirt particles. As this happens, the filter now has tiny dust particles trapped inside the folds and fins of the material it's made from. This can restrict the smooth flow and reduce the volume of air through the filter.
For the filter to maintain maximum airflow and ensure the vacuum sucks as efficiently as it blows, it's required that you clean the filter often.
Here is a list of things that happens when you don't clean your vacuum filter:
- The filter becomes clogged with dust and dirt particles
- The volume of air passing through the filer reduces
- The vacuum cleaner uses more energy than necessary to force air through the clogged filter, causing overheating.
- The vacuum loses suction and wouldn't perform as expected
- Eventually, the vacuum cleaner stops working after it is clogged and uncleaned for too long.
