Review on 🔍 Enhanced Replacement Filter: Whirlpool WHA4FF5 Premium Capacity by Wayne Ohlrogge

We bought this hot tub in place of Dupont and installed it on January 29th. Less than 2 months after the installation had to be changed again. The Dupont brand was slightly better, so the moral of the story is in the reviews of how long the filters last. UPDATE: I'm downgrading the rating to 1 star. Last time I estimated how long it took. I measured this time. This went on for 30 days and our water pressure dropped and smelled badly of sulphur. We bought Blue brand charcoal and mud, will install them and see if they last longer. The Dupont and Whirlpool brands have been removed from our list for the time being.
