How long do hot tub filters last Sunday, 26 January 2014  |  Jon Pennington

In general a hot tub filter will only last 1 year, that is 1 year of continual use, if you rotate your filters i.e. have 2 pairs then the filter will last 2 years.

What to look out for

• If the filter is fluffy
• if the filter pulls in at the waist
• if the filter is light green in colour
• cracked filters
• filters with holes in
• heavily discoloured filters

You may also want to change your filter if they have heavy amounts of slime on and inside the pleats.

Why change the filters?

If the water cannot flow through the pleats easily this will cause a restriction to the hot tub pumps and will either burn out the motor or pop the Capacitors.

If you are struggling to keep your water clean the filter might be the cause.
