What Happens if You Use a Vacuum Without a Filter? 

A shop vacuum is a very effective and strong tool for cleaning areas covered with dust. It is an easy function that lets suck all into a canister and allows the user to remove the dirtbag, clean it, and then set it inside again. 

The Function of a Filter in Vac

Before explaining what happens when you do not want to use a filter, you should know what a filter is needed for. A filter basically removes dust or solid particles from what you are cleaning. A filter in a shop vacuum collect impurities such as dust, solid particles, or nails in your house. 

In Wet Surfaces

Now you should pretty much have an idea about the purpose of a filter. You can use water with a shop vacuum. But then you can only use it for cleaning wet surfaces or open space and only after removing the dust bag. Otherwise, your vacuum might get clogged due to getting blocked. 

No to Filter: Yes to Mess

Using no filter creates an issue of the dirt being thrown back into your space. This just exhausts the very reason for using a vacuum. No use of a vacuum filter shortens the lifespan of your shop vacuum. Also, the dirt might get messed up inside the metal container. The dirt might leak out of the shop vacuum.

How to Use a Shop Vacuum Without a Filter? 

A shop vacuum is an easy system to collect dust from your surroundings. These are “good to have around” tools in daily life. All you need to do is suck the dust-out. Now to the most frequently asked question. If you have decided not to use a filter then we want you to know the safest way to do so. 

Ensure if You’re Okay With It

At first, make sure you know that your shop vacuum can do without a filter. Otherwise, you are just shortening the lifespan of your shop vacuum. Placing water on the bottom of the container will allow some of the dust to be trapped but not all of them. 

Remove Bag for Use of Water

If you are using water, then you must remove your dust bag while cleaning wet debris. Some models use special filters for wet debris cleaning. But with no filter use it only in open areas as the dust might get thrown back into the air. 

When Is Water Okay?

Use of water only increases hassle nothing else. Cleaning large wet areas is not a good idea. But a broken pipe is fine. When you use water instead of a vacuum filter, you probably need to empty it every 30-50 seconds. 

Because the vacuum fills up very quickly. And when it does it has a high chance of getting clogged. Firstly, remember to have a hose from where you can the output. This lets the liquid go directly out.
