Each time about 6 mos, I change filters they fall apart Filters do not last without dissolving.
All around good product.
Arrived on time, like the products.
No problem with the new filters. Hot tub is working great!!
They are hot tub filters and perform as advertised.
This product is being used in a hot tub and am pleased at the water clarity which means the filter material has excellent quality.
These filters are junk in a hot tub. The blue plastic starts flaking off a few months. Litters the tub with blue debris. DONT BUY!
I use this filter for my spa and this is the same product that you see at other sites but a much lower price!
Had a little trouble finding correct size filter for our small Viking hot tub but these fit the bill! Thanks Spa Depot!
Works and fits as expected, good product.
