Spa Marvel Filter Cleaner is a powerful hot tub filter cleaner that doesn’t utilize harsh acids or bleach, and removes and loosens oil, hair, dirt and grime that becomes lodged in the fabric of cartridge filters. One bottle of Spa Marvel Filter Cleaner provides 8 filter cleanings. At a fraction of the cost of other filter cleaning products on the market, Spa Marvel Filter Cleaner is the best and most economical filter cleaning agent available.
A thorough filter rinse once a week, with a proper complete monthly cleaning using Spa Marvel hot tub filter cleaner, will suffice for the majority of hot tub users. Keep in mind that the filter takes out whatever is put into the spa, and all it takes is one bather who is covered in body lotions to foul a clean filter.
The frequency at which filters need to be cleaned, is dependent on spa use. Clean your filter at least once a month, or more often if you have a smaller filter and a higher bather load. If you have a low-circulating spa with a small filter, and your spa is used by multiple people every day, you may have to properly clean your filter every week.
