FREQUENTLY ASKED QUESTIONS

I can’t find my cartridge on the web site, what can I do?
If you have watched the “How to order my filter” video on the home page and followed the steps on the filter finder tool, then simply call customer service at 310-909-4466 so that we can help you order the correct filter.

How often should I replace my filter?
All cartridge filters should be replaced once a year. Just think, all of your hair, body oil, dead skin, body lotion, saliva, sweat and misc debris from one’s body all gets collected into the filter. Even though we clean the filter regularly, there is still 10-15% of debris that cannot be seen with the naked eye left on the filter. We recommend that you use a filter cleaning solution every 1-4 months depending on how often you use the pool or spa.

I just bought a used spa or moved into a house with a pool. Do I need to replace the filter cartridge?
Absolutely! If you don’t replace the cartridge you will be re-circulating all of your hair, body oil, dead skin, body lotion, saliva, sweat and misc debris from the previous owner. Illness can result from having a dirty filter.

How Does A Cartridge Filter Work?
Swimming pool filter cartridges work by allowing water to pass through a very fine filter surface. This filter surface captures any impurities that attempt to pass through and hold them until you clean the filter cartridge or replace it. Cartridge filters have more surface area than sand filters. This allows for fewer clogs and much easier maintenance. Cartridge filters also operate at a much lower pressure than sand. This causes less backpressure on the pump so you have a greater flow of water through the system. The swimming pool filter cartridges can filter out anything down to 5 to 10 microns in size. To put this in perspective, a single grain of table salt is about 90 microns in size. Anything below 35 microns is invisible to the naked eye. Swimming pool filter cartridges are extremely popular because they are very easy to maintain and relatively inexpensive. Basic cartridge maintenance can be performed by simply rinsing off your cartridge with a garden hose or soaking them in detergent. However, the best way to ensure a clean and sparkling pool is to just simply replace them.
