Why Are Hot Tub Filters Important?
Even if you regularly add chemicals to your hot tub, without a filtration system the water would still quickly become dirty; filling up with oils, lotions, as well as small debris like sand and leaves. This would not only look bad but also cause some water quality issues such as foamy or cloudy water.
For this reason all hot tubs come equipped with a micro filter. Hot tub filters are designed to trap smaller debris like sand, as well as oils and lotions that build up in the water with use. By removing these from the water, the filter helps to keep the water cleaner, clearer and easier to maintain. It also protects the hot tub pumps from sucking in debris that could clog or damage them.
How Often Should You Clean Your Hot Tub Filter?
Over time, the amount of debris trapped in your hot tub filter increases to the point where it can no longer effectively do its job and it will need to be cleaned to restore it to its peak working condition.
Every 1-2 weeks, remove your filter and rinse it off with a hose or in your laundry tub to remove any dirt or debris caught in it. Once rinsed you can put it right back in the hot tub. If you find that there is dirt and debris caught deep in the filter pleats that simply won’t come out, you can buy a tool like the Filter Flosser to provide a deeper clean of the filter.
Along with these basic cleanings, you should also chemically clean the hot tub filters every 3-4 months to remove trapped oils and lotions. To chemically clean a hot tub filter you will need to purchase a specialty hot tub filter cleaner.
Add the filter cleaner to a bucket of water large enough to fully submerge the filter. Place your filter in the bucket with the cleaning solution and let sit for at least 3-4 hours. When the time is up, remove the filter and rinse it with a garden hose to wash off any cleaner and debris left on the filter.
For best results, let the filter fully dry after a chemical cleaning before putting it back into the hot tub. To ensure that your hot tub doesn’t run without a filter during this time, we recommend rotating between two sets of filters. While you clean one, the other can be put into the hot tub. When it is time to chemically clean that filter, the original can be put back in the hot tub and so on.
Why Do You Need To Replace Your Hot Tub Filter?
Even with regular cleanings your hot tub filters will eventually need to be replaced. This is because over time the filter fibres begin to stretch, allowing larger and larger debris to pass through them. Letting the filter dry after a chemical cleaning will help to tighten the filter fibres again but they never quite go back to the way they were when new. Eventually the filter fibres will loosen to the point that they can no longer effectively keep the water clear and will need to be replaced.
How Often Should Your Replace Your Hot Tub Filter?
Your hot tubs filters should be replaced after 6-12 months of use, depending on how often you use your hot tub. If the hot tub water is fresh but still has a hard time staying clear, chances are your filters are ready to be replaced.
Note: If you’re rotating between 2 sets of filters you will only need to replace your filters every 12-24 months as each filter will only have been working for half the amount of time.
How Can You Extend The Life Of Your Filter?
The key to a longer hot tub filter life is regular cleanings and well balanced water. Following the cleaning schedule outlined above is the single best way that you can increase the lifespan of your filters. Even well maintained filters can be damaged by poor water balance, however, so make sure to also regular test and balance your water; paying special attention to the level of sanitizer in the water.
