A filter cartridge performs the work of trapping all the impurities present in the water of the spa. Since these cartridges trap all the dirt, it is obvious that they get clogged. Back washing these filter cartridges is one of the best ways to keep the cartridges clean. All you need to do is use a garden hose and rinse off all the dirt accumulated on the filter cartridge. The cartridges must be back washed once in every two-three weeks and a deep cleaning session must be performed once in every three months. To deep clean the cartridges, soak the cartridges in a cleaning solution and rinse them off the next day.
Like every other machinery, even the filter cartridges fray out after a prolonged use. This is when you must buy a spa filter replacement cartridge. One thing that must be kept in mind is that the replacement cartridges must be of the same brand as that of the original cartridges. For example, if you own Bullfrog Spas, try and purchase a set of Bullfrog Spa replacement cartridges. Make sure that you note down the specifications of the original filter cartridge as this will make your search easy.
Another important tip that must be kept in mind by every spa owner is to always keep extra filter cartridges. When you take out your filter cartridges for cleaning, you can use the other one. Also, if your filter cartridges stop working suddenly, you will not have to rush to the retail store to purchase new cartridges. Instead, you can use the already kept filter cartridges and order spare cartridges online at an economical price.
