SpaGuard Filter Cleaner deep-cleans your spa filter cartridge, removing the body oils, dirt, grime, and scale that ordinary rinsing leaves behind. Your filter is the hardest-working part of your spa — it's constantly pulling contaminants out of the water. Over time those oils and minerals embed themselves deep in the filter's fabric, where a garden-hose rinse simply can't reach.

When that buildup clogs the cartridge, everything downstream suffers: water circulation drops, filtration gets less effective, the water turns cloudy more easily, and you end up using more chemicals to compensate. A properly cleaned filter reverses all of that. SpaGuard Filter Cleaner breaks down the embedded gunk so water flows freely again, your filtration works the way it should, and your cartridge lasts longer before it needs replacing — which keeps money in your pocket.

It works on all types of spa filter cartridges and can be used two ways: a quick spray-on clean, or a deeper overnight-style soak for heavily loaded filters.
