You should always take a closer look at your Jacuzzi® Hot Tub filter before replacing it to ensure that all traces of dirt and debris have been removed.  It is also very important to check for signs of wear and tear, particularly if your Hot Tub filter is nearing the end of its lifespan. Look for cracks around all visible plastic and ensure there are no rips or tears in the main body of the filter.

DO let your filter dry naturally
High quality filters are designed to withstand varied temperatures but applying direct heat such as a hairdryer or even placing it on a radiator could warp and damage the plastic or effect the performance of your filter.  

DO make sure you have a filter fitted in your Hot Tub before turning it on.
As we have already mentioned, the Jacuzzi® Hot Tub filter removes dirt and debris ensuring the water is kept clean. It is also an important part to stop the debris from being sucked into the pump and causing damage. The pump is one of the more expensive parts to replace, therefore we do not recommend running your hot tub without a filter.
