Last week, we discussed, in depth, the three kinds of filters on the market, since we’re on a mission to help you make a well-informed filter decision. Based on effectiveness, it was easy to see that most people would probably go the DE filter route. Now let’s look at some other factors. Required routine maintenance is definitely something to consider when choosing a filter. After all, the point of your pool is to swim in it, not spend all your time baby-sitting it! It’s worth noting that as your filter fills with debris, it causes increased pressure and decreased flow rate. Many factors play into how quickly your filter fills up, but it’s always good to remember that clean filters decrease energy loss. In general, a filter should be backwashed when your pressure gauge reads 8-10 lbs. higher than the original clean startup reading. A sand filter requires backwashing every 1-2 weeks, but actually replacing the sand every 4-5 years or so. Since sand is so inexpensive, we can see why the sand filter is so common, despite its sad lack of effectiveness of actually cleaning your pool water. Cartridge filters require more hands-on, labor intensive maintenance. Read: If you want the dirt and debris off your filter, soak it, hose it down, scrub it and chlorinate it with good, old-fashioned elbow grease. And, inevitably, it will need to be replaced, depending on what kind of cartridge filter you’re using. This kind of maintenance can be something of a turn-off for some folk. If it were us, we’d rather spend the time practicing our cannon balls in the deep end of our pool! Onward to our favorite filter option. DE filters require the usual regular backwashing along with adding a specific amount of DE each time the filter is backwashed. Other than that, the nylon material coated grids need a thorough cleaning and inspection only once a year to keep things in tip-top shape. Not bad! Now you can get back to working on some serious pool recreation. Anyone up for a game of water volleyball?
