Spa in-Filter Mineral Sticks Parts for Hot Tub Filter Cartridge, Last for 4 Months, Yellow, 2PCS

Very good produce. Performs as advertised and as expected. Really reduces the need for chemical additives to keep the apall chemistry within specs.

These work well and are a great alternative to higher cost units from the local spa dealer. They fit perfectly and help keep your water looking and smelling fresh and clean.

I’ve been using the Bilinavy Spa In-Filter Mineral in my hot tub, and it has made a big difference. The water feels cleaner, softer, and much more refreshing—almost like having a mini spa at home. It really helps cut down on that chemical smell and keeps the water feeling fresh for longer. Installation was quick and easy, and it fits right in without any trouble. My skin feels better after soaking, and I don’t notice the dryness I used to. A simple upgrade that makes hot tub time even more relaxing!

I never even noticed these weren't Nature-2 when I set up the subscription. But haven't noticed the difference. visually, or after installation.They do the job, reasonably cheap with a 4-month 'subscribe and save'.No Complaints.

Far cheaper than any other mineral stick I have seen. These are a hidden secret to keeping your water sparking clean. I change my filter 2x a year and use a mineral stick with my UV light filter. I use very very little chemical. No itchy bromine, a tablespoon of spa chlorine after each use. My water is crystal clear all year long.

These are so easy to use. I put one in my hot tub and just forget it for months. It sits in a corner out of the way and not really noticeable. Love them.

I have been using this stick for years along with some non chlorine cleaner, and it works great! Many years of doing this, and hottub is always sparkling! Just change out every 4 months.
