Product is for my jacuzzi, works perfect.

Great filters at a reasonable price
These filters get replaced every 6 months or faster depending on your situation. They have always been the perfect fit and last a long time with minimal maintenance. They arrive on time ready to use. Highly recommend.

Great filter
The only filter brand Iâll use in my hot tub. I was buying filters from my hot tub store and the filters didnât fit properly and my water was always cloudy. After switching to this brand Iâve had pristine water and it actually fits the way a filter is supposed to.

Great value
Compared to buying these in a store, you will save money buying these here. Same filter, same durability for far less.

2021 Coast Spa-Apex L: compatible
I have a 2021 Coast Spa Apex L model that came with an unmarked, no model# or manufacturer name dual core filter that lasted about 15 months. This Unicel filter fits perfect. Time will tell how it works but most reviews are good.
xdvr –
Yup
Works as advertised.
Kalan Elijah Rylee –
Works as advertised and quality is good. Filters out my hot tub great! Also generally cheaper to buy on amazon then in stores like home depot. Highly recommended. Definitely buy this over a hot tub store, you’ll pay way less and works the same!
Hans Dekkers –
We installed a used tub, with an older filter. Cleaned the filter, but did not get the results we hoped for. With this Unicel, in 24 hours the water was cleared out. Excellent product.

Les plus : eau plus claire ,utilise moins de brome et de produit stabilisants.Les moins : il se nettoie assez facilement à lâeau, mais demande un peu de temps pour bien déloger les résidus.
