Why are filters essential?
Filter cartridges are an essential feature of a hot tub pump as they filter out dirt and grime from the water in the hot tub to help keep it clean and healthy. They also prevent this dirt from getting into the pump and heater which could cause damage and reduce its lifespan.
How do the filters work?
These filter cartridges work by catching dirt and grime when the water is pumped through them. As your pump will usually be continuously cleaning and filtering the water when it is turned on, this dirt can quickly build up, especially when the hot tub is regularly used.
How often should I clean and/or replace the filters in my hot tub?
Between each use and at least every 3 days you should remove the filters and give them a wash to clean this dirt off the filter. Every few weeks depending on intensity of use, old filters should be replaced with new ones (especially when they become harder and discoloured). The more often you use your hot tub the more often you should clean and replace your filters. Showering before using your hot tub can significantly help reduce the deterioration of your filter.
What happens if I don't replace the filters?
Failure to wash out your filters can result in them becoming soiled and clogged which will ultimately constrict water flow. This will put extra strain on the pump motor and potentially cause a mechanical breakdown. Poor filter care and maintenance is the number one cause of pump/heater failure.
