The filter has to be the most important part of your spa or hot tub. Its purpose is to filter out solid organic material that can not be removed throught the use of chemicals. Generally hot tub filters take out material down to 5 microns. The filters ability will depend on how many "square foot" of filtration it has, but will be sized correctly by the hot tubs manufacturer to ensure adiquate water quality.

Hot Tub filters should be changed between 6 months and 1 year, your hot tub filter may clean up with a hose but it will start to put back pressure on the pump if it not replaced and could burn the motor out. This is not visible by looking at the filter

Cant find the filter your looking for? 70% of the filters we sell are either a C-4950 (long filter with a hole down the middle that fits in with a basket on the top or a PWW-50 that are usually fitted in pairs into a hole that looks like a letter box, these are common to Spaform hot tubs. 

Hot Tub Filter Cleaning

Generally filters should be cleaned as a minium one every 3 weeks using a suitable hot tub filter cleaner and preferably using a waterwand filter attachement for your hose. Filters should never be pressure washed as this will break the fibres down very quickly. The filter should also be left to dry after cleaning to ensure its maximum life span. If you do not allow it to dry the fibres in it will go very hairy very quickly and hold bacteria very easilty.

If your filter is starting to look a bit hairy or dirty and it time for a new one please select your brand from the table below all our filters are producted with Microban antibacterial protection.
