A dirty filter and scaled pipes make the water harder to keep clear, and the fix depends on which part needs work. A filter cleaner works on the filter itself, a pipe cleaner works on the plumbing, and a replacement filter has to match your tub's size, fitting style and part number.
Start with the job, because a filter cleaner is for the filter itself and a pipe cleaner is for scale, soap and sediment in the plumbing. Then check the product page for the method and the time it needs. If you are buying a replacement filter, match its size, fitting style and part number to your old one before you order.

They are made for different jobs. A filter cleaner is for the filter, and a pipe cleaner is for scale, soap and sediment in the pipework, so follow the label for the job you need.
Check the size, the fitting style and the part number, then match them with your old filter. Some product pages cross-reference part numbers from several manufacturers, which helps when you are checking.
Some product pages describe a soak in filter cleaner solution as an alternative to a quick spray. Follow the product label, and let the filter dry before you refit it.
Filter life depends on how often the tub is used and how well the filter is cleaned. Check the replacement interval in your manual or on the product page, because it varies between filters.
