Like how it works to clean water and easy to install and clean when gets dirty worth getting 2 at a time so you have extra one to use while other one has over night soak for good cleaning and then time to dry out before using again
This is my second time ordering and it came quickly. I bought last one and it helped keep the water clear from Dec to May. 1st time in five years that I haven’t had to empty and refill or not use the tub over the winter. Definitely recommend buying this filter to others that use their tubs 3-5 times a week
