Find Hot Tub Filters by Size & End Cap
Nothing is more important in maintaining good hot tub water quality than the filtration system. Dirty, clogged or worn-out filters will fail in their job of trapping contaminants and put an unnecessary strain on the spa pumps.
Hot tub filters should be cleaned regularly and replaced every 6 - 9 months.
If your water quality starts to deteriorate unexpectedly then the cause is very likely to be old or dirty filters.
