What is The Function of a Filter in a Shop vac?


The device is very powerful and multifaceted. It is designed in a way that they can take in anything. Talk of dust, screws, metal shavings and any other kind of rough debris around your home.

That simply defines the work of a filter in your shop vac.


How a Shop Vac Works


Generally, shop vacs functions in a similar way as other vacuum cleaners. However, it has a small modification on its model. It works more efficiently than traditional vacuums.

This is due to the fact that it can take in bigger fragments of debris and clear wet spillage normally found in industries and workshops.

However, a shop vac is still usable in your house. Nonetheless, note that without fine pointed attachments, it gets hard for the vacuum to collect all fine fragments of dirt.

When cleaning wet substances, you can take away the filter. This is wholly dependent on the design of your vac. There are shop vacs that have filters specially made to clean wet surfaces.

However there is an amount of liquids they can’t work on. Always pay attention to the sound of your shop vac when cleaning.

Most models come with the floating ball mechanism which puts off the motor once the tank is filled. It produces a high pitched sound to alert you that you must now turn it off and clear it.

Cleaning Wet Surfaces or Fluids


It is best to use foam sleeve filter to clean wet areas or swimming pools. HQRP 2-Pack Foam Sleeve Filter is best in this case. It keeps any kind of dirt from getting into the vacs motor.

On top of that, get a collection bag that is resistant to tear. This is not optional if you are vacuuming extremely dirty liquids that could contain large stone or pebble particles.

The bag traps the fragments in as the water gets pressed inside the chamber. Once done, clear the bag and dislodge the fluid.

Number three filter collects fine dust, ashes and powder. It is referred to as the finer filtration system. Ensure that your vac is harmonious with the three filters because all models are not.

The answer is yes. You can, but we honestly don’t recommend this practice. A filter will help you escape a lot of trouble.
