If you've just installed a salt water pool system, you may be wondering what kind of filter is going to best meet your needs. Salt water filters for your pool work just like other pool filters, so choosing the right one is essential.
There are three basic kinds of salt water filters. Sand filters are the most versatile, and they offer perhaps the best cleaning capability for your pool. Whether you have a semi-public pool or simply a backyard oasis, a sand filter will give you the best possible water quality. A cartridge filter is far cheaper than any of your other filter choices, but they simply aren't effective as sand. Moreover, you have to replace them more frequently, so while the initial cash involved is low, the cost builds up over time. DE filters tend to offer great water quality results, and they're a good choice for lots of families.
Which one is right for me?
Figuring out which one to install in your pool is based on a number of factors. First, think about how frequently your pool is used and who uses it. Your pool will need a far better filter if it is used on a daily basis by a number of people. Second, consider the size of your pool carefully while you pick out the right filter. Finally, think about how much maintenance you want to undergo as you work with your filter.
For longer term use, sand is the answer.
For low maintenance, a cartridge filter is your best bet.
For extremely clean water, DE filters are the number one choice.
Keep these points in mind, too, as you search for salt water filters for your pool:
DE filters and cartridge filters simply aren't the right choice if you have a pool that sees more than ten occupants per day. While lots of manufacturers will suggest that their DE or cartridge filter can be used in that manner, it's just not the case. The debris in your pool can clog the filter, and you'll end up replacing it with a sand model instead.
Sand models do tend to create a level of inefficiency as they waste more water than any other type of pool filter with the weekly backwash. If your main concern is water efficiency, don't purchase a sand model.
DE filters are illegal in some places. Check your local regulations carefully before you make a purchase.
Finding the right salt water filters to meet your needs can be difficult, but there are two great ways to get recommendations that will actually work for your pool. First, chat with your local pool supply store. Some even offer home visit consultations so you can be sure to get something that meets your needs. Second, talk with other pool owners. If you don't personally know any, spend some time networking online with forums and bulletin boards. Find other pool owners who have similar experiences, and you'll be sure to learn from their mistakes and success with salt water filters.
