Which type of swimming pool filter system is best?
First you must define best! Now with that background, which filter is best? I often use this question to gauge who I am talking to in a pool store. Just ask: “Which filter is best” and then listen for the answer. There is only one correct answer to that question: can you please define best? If the answer is any of the three, someone is trying to simply sell you something. • If you want bulletproof – sand is a great choice. • Low maintenance would lead one to cartridge. • The cleanest water might lead you to DE. • All filters work. • You can add a little DE to a sand or cartridge filter to increases its ability to filter small particles. • Flocculants can be added to the pool water to create big particles out of small particles (think – flocks of birds are easier to see). • Cartridges that become fouled can be replaced. My recommendations? I would go with a high-end cartridge filter. The reason is that no one really wants to have another item on the to-do list and good cartridge filter
