Cartridge Filters Are Great For Many Reasons.

  • They do not require Diatomaceous Earth or any other add in product for proper filtration
  • They only need to be cleaned on average two to four times per year
  • They are usually easy to take apart and put back together
  • They remove a very small particle (down to 9-11 microns) which is smaller than we can see
  • They provide crystal clear pool water with the least amount of effort

 As far as size goes, it depends on how many gallons your pool is and how often you want to clean your filter. Anything up to 20,000 gallons can use the 300-350 sq. ft. filter systems and you will most likely need to clean them every 3-6 months (depending on how much dirt and debris enters your pool). If you went with a 420-450 sq. ft. filter for the same size pool with the same amount of debris, you could expect 1-2 months longer in between cleanings. A 30,000 gallon pool needs at least the 420-450 sq. ft. filter and a 40,000 gallon pool needs at least the 520-580 sq. ft. system. With that said, there are many brands to choose from. Any brand will do the job but here are my favorites.
