Managing Hot Tub Filters

Hot Tub Filters

Hot tub filters are designed to remove suspended particles, oils, grease and other detritus from your hot tub spa, making them one of the most vital parts of the hot tubs inner workings.

If you keep your hot tub filter clean, not only does it improve the efficiency of the filter, but it will also make the water aesthetically pleasing to the eye to the point that you just can’t wait to jump in and enjoy the relaxation!

The best way to clean your hot tub filter component is to engage in a regular routine, cleaning approximately every two to three weeks depending on how often you use the spa and what product you use to sanitise it. Obviously it is wise to stick to the product instructions though as they can vary between different cleaning products.

The first stage of cleaning should be to remove the filter cartridge from its position in the hot tub and wash the filter out under the tap or hose. Care should be taken to allow the water to flow against the filter at approximately 45 degrees and all debris, grit and other nasty products removed. The filter should then be soaked overnight in a hot tub filter cleaner solution or cleaned in a dishwasher with a product such as ‘Filter Bright’ then rinsed out and let dry naturally.

Generally, Hot Tub filters will only need to be replaced every twelve months but in order to maximise their life you should endeavour to keep the water in the spa in proper ph balance, never be rough when cleaning the filter otherwise unnecessary damage can occur, and most importantly, allow the filter to dry out completely before using it again in the spa. It is widely recommended that you always have two sets of filters at one time in order to let the filter cartridge dry out completely.

Even though a Hot Tub filter cartridge should last about twelve months, there is no real defined life span as they have no moving parts and so there are a number of factors that can help you to decide when the filter cartridge has to be replaced. The most obvious of these is a physical failure in the filter such as a crack or tear in the body or mesh. Other factors to look out for include, lower flow rates, shorter periods between cleaning and general poor water quality.

When your Hot Tub filter needs to be replaced, the easiest way to make sure your spa remains fresh watered and clean is to choose the same filter that was previously installed as different size filters are available and not fully cross compatible. This can be done through manufacturer name or by using the serial number found on the filter.

Hot Tub Spa filters are a vital component for your hot tub or spa and a little effort in regular cleaning and knowing when your filter cartridge needs replacing will ensure that relaxing hydrotherapy bathing can be maintained.

Good info. I must admit that I never thought about changing the filter but I will certainly consider it!

Make sure you protect them and keep them very clean. You do not want outside waters clogging them up and bacteria to grow.

Make sure to change them regularly as well. Proper maintenance is key to keeping your hot tub lasting a a long time!

They are not as hard as people think to keep running well, as long as you keep up on them consistently. Ask your spa dealer or local pool store if you need help.
