It is a documented fact, that the vast majority of issues consumers face when dealing with a problematic hot tub can be traced back to its filter. Before paying for expensive service call, check the filter PRIOR to contacting a technician.
Most hot tub manufacturers recommend that a filter should be changed at least once a year. Dirty filters can be hazardous to your health, damaging to hot tub components and can actually void out a warranty.
Obviously, common sense dictates that you should always turn off the power to your hot tub before locating and inspecting the filter. Your hot tub manual will provide step-by-step instructions in regard to the easiest way to locate, remove and replace the filter.
It is sometimes possible to clean a filter and reuse it, for a limited period of time, until a new filter can be located. This should only be done if the filter is free of cracks, does not feel limp and can still hold its shape.
If you do decide to reuse a filter, it should be discarded after a period of two years. As a filter gets older, its fibrous material stretches. When this happens it allows larger particles of debris to slip through the filter and clog the hot tub pump.
Remember… these filters are much less expensive than a replacement pump. Make it a point to check your filter at least every four to eight weeks. It will probably save you money, in the long run.
(Caution: if the filter is broken or damaged in any way, do not attempt to reuse it… especially if the element, located in the center of the filter, is loose. It is best to keep an extra filter on hand, as an alternative to recycling.)
If you are unsure of the size of your filter, you can measure it quite easily. For the diameter, measure the widest point, at the end of the filter, from the outside edge to the outside edge. Measure to the nearest 1/16 of an inch. For the length, measure from the outside edge of one end cap to the other.
Another way to locate the hot tub filter replacement, you’re searching for, is to visit the website of the company that manufactured your particular tub. Nine times out of 10 that information is contained somewhere onsite.
