A couple weeks ago we talked about the main differences between cartridge filters and sand filters. Last week we dove deeper into sand filters. Now we will take a look at cartridge filters and what they can do for your pool and why they may be a better option for you than sand filters.
Cartridge filters are both energy efficient and cost-effective. There is no loose filter media like sand used inside. Cartridge filter systems push water through a polyester spun pleated filter that catches dirt and debris.
Cartridge filters remove particles as small as 10 microns, and because of the large surface area, they have less resistance and perform well at slower speeds, which conserves energy and reduces your running costs. Also, they don’t require any backwashing, which can be a big plus as backwashing is one of the biggest causes of pool water loss. Instead, the cartridge filter is removed from the tank and sprayed down with a garden hose (watch this great video "how to clean your filter" showing you how to do that on our video page). So technically, it requires a little more elbow grease, however, cartridge filters require cleaning less often. Cartridge filters require deep cleaning once or twice a year and need to be replaced about once every three years.
Simply, cartridge filters are better for those who have trouble keeping their pool clear and want to spend less time maintaining the pool. This is the reason why they are widely preferred by residential pool owners. Sand and cartridge filters are both great options for your pool.
