Shop Vacs are extremely useful and can be used for a variety of things. They’re easy to cart around and are short so they are easy to fit into smaller spaces. Large bulky vacuums make it difficult to clean enclosed spaces. Shop vacs make cleaning a car or big messes a breeze. All the dust and debris that is getting picked up with a shop vac might make your shop vac filter very dirty. Your shop vac will begin to lose suction, spit out dust, and stop working efficiently if the filter is dirty. Luckily, cleaning a shop vac filter is very easy and you can go back to cleaning in no time. Here is a description of the easiest way to clean a shop vac filter.

When to Clean Your Shop Vac Filter

There is not a recommended time that you should clean your filter. It doesn’t necessarily have to be cleaned every couple of weeks or months. It depends entirely on how often you use it and what you suck up with your shop vac. A shop vac that only gets used every couple of weeks to suck up some cobwebs isn’t going to need to be cleaned as often as one that gets used every day for serious messes. The hose on your shop vac will seem like it’s jammed if the filter needs to be cleaned. Most of the suction will be gone and the vacuum will start to puff out dust every time it is turned on. Don’t worry, your shop vac isn’t broken, it can be fixed with a simple cleaning of the filter.
