What is a good water pre-filter

[Coleman]

Wondering what is a good water pre-filter to fill a hot tub with? Can someone give some ideas on which way to go and be used multiple time?
Thanks Coleman

I would just google hot tub pre-filter or go to any hot tub store.

Eco one and Spa marvel make two pretty decent ones that don't cost a fortune
