How to Clean a Cartridge Filter

Cartridge filters have been used to clean and remove unwanted particles from water since the Mid-1960s. Whether you have a pool or spa, it is important to understand how to clean the filter as regular maintenance will ensure the filter lasts as long as possible.

Items needed to Clean a Filter

  • Filter Water Wand (Recommended)
  • Garden Hose
  • Bucket
  • Filter Cleaner

Regular filter cleanings should be performed every month and should take no more than 30 minutes once you get the hang of everything. The best time to clean your spa filter is when you are draining and refilling the tub. There may also be times it needs to be cleaned before then. If the water is balanced and properly sanitized, yet the water does not seem as clear as usual, it doesn’t hurt to give the filter a good clean.

Spraying a Filter with Cleaner

Filter life depends upon the type of tub you have, the brand/type of the filter, the usage of the pool or spa, and the balance of the water. If your filter is unable to support itself when you stand it on its side or the pleats have become damaged, it is time to replace the filter. Check your owner’s manual or the manufacturer to ensure you are using the correct filter for your pool or spa.

When cleaning the filter there are a couple of options. You can use a cartridge tab cleaner or a spray on cleaner depending upon your preference. Cartridge tab cleaners require you to soak your filter in a bucket for a half an hour in the cleaning solution and then rinse clean.

Filter Water Wand in Use

With a spray cleaner, you saturate the filter with the solution and let it sit for 5 to 10 minutes then rinse it clean. Both options work equally well and are priced similarly. Follow the product instructions for specific steps to follow.

When rinsing the filter, some customers ask if there is a better option than using the nozzle on their hose that is able to thoroughly clean and not damage the pleats: We recommend using a Filter Water Wand. This device attaches to a garden hose and is designed to clean safely between the pleats faster while using less water. AquaVision Pool & Spa carries the Filter Water Wand as well as all of the cleaning products you might need for both pool and spa filters.

Maintaining a proper water balance is key to the extension of your filter. Be sure to regularly have your water tested and maintain the sanitation levels required per your sanitation system that you use. If you have any questions, reach out to your local pool and spa store or, if you are in our area, call AquaVision Pool & Spa with any questions you may have.
