How often am I supposed to replace hot tub filters?

Most folks swap them out every year, sometimes sooner if the water is hard or the tub gets a lot of use.

How do I know what filter to get for my hot tub?

Check your spa manual or look at the label on your current filter, then match the size and model so it fits and seals right.

The fuzzy surface grabs oils from sunscreen, lotions, and hair products so your water stays cleaner between filter cleanings.

It will turn on, but you should not run it that way because dirt and gunk will shoot into the plumbing and the pump can get damaged.

If the pleats are grimy, the jets feel weak, or the water stays cloudy even after cleaning the filter, it is probably time for a new one.

The water gets cloudy, the jets lose power, and you might strain the pump which can lead to expensive repairs later.
