SpaPure Filter Cleaner | Hot Tub Cartridge Cleaner

• 1 x SpaPure Filter Cleaner (liquid concentrate — spray bottle not included for the spray method)

• Heavy-duty formula — cuts through stubborn oils, soap residue, scale, and grime
• Two ways to use — quick spray-and-rinse, or a deep soak for heavily loaded cartridges
• Restores filtration and flow — clears the pleats so water moves freely again
• Extends filter life — regular cleaning means cartridges last far longer before replacement
• Supports clear water — a clean filter is the foundation of balanced, sparkling water
• Works with every system — compatible with chlorine, bromine, biguanide, mineral, and ozone setups

The cleaner's formula breaks down the oily, greasy film that ordinary rinsing leaves behind, and dissolves the mineral scale that hardens onto filter media. Together those two actions clear out the pleats so water can flow through freely again — restoring both the efficiency and the lifespan of the cartridge.

That oily buildup matters more than it looks: it's the perfect hiding place for the contaminants your sanitizer is trying to control, and a clogged filter can't capture new debris. Cleaning the filter is often the missing step when water stays cloudy or dull despite balanced chemistry.

Pro Tip: If chemicals keep "disappearing" or the water won't clear no matter what you add, clean the filter before reaching for more product. A fouled cartridge is the single most common reason a spa fights its owner — and it's an easy, cheap fix compared to dumping in more chemicals.

Always add chemicals to water, never water to chemicals. Choose the spray method for a quick clean or the soak method for a deeper one.

Spray Method (quick clean)

1. Remove the filter from the spa and rinse off loose debris from the pleats.
2. Using a spray bottle (not included), spray SpaPure Filter Cleaner over the cartridge, working from the top down.
3. Allow the cleaner to stand for 15 minutes.
4. Rinse the filter completely, return it to the spa, and resume normal operation.

Soak Method (deep clean)

1. Add 16 ounces of cleaner to 2½ gallons of fresh water in an appropriately sized plastic container (never steel, metal, or aluminum).
2. Mix thoroughly, then place the cartridge into the solution.
3. Soak the filter for 30 to 60 minutes.
4. Rinse the filter completely, return it to the spa, and resume normal operation.

Clean filters every 6 to 8 weeks on chlorine or bromine systems, or every 4 to 6 weeks on a biguanide or other system.

Pro Tip: After rinsing, let the cartridge dry before putting it back if you can. Spraying or soaking, then a thorough rinse, lifts the cleaner and the debris out of the pleats — and giving it a chance to dry helps the fibers recover their shape so the filter seats and seals better when it goes back in.

SpaPure Filter Cleaner is compatible with all sanitizer systems — chlorine, bromine, biguanide, silver/mineral, and ozone. Because it cleans the filter hardware rather than treating the water, it fits any spa and any routine.

It's designed for cartridge filters (the standard in portable spas and hot tubs) and works as a companion to your whole care lineup — clean the filter before a stain & scale removal treatment, and any time you drain and refill. Use a plastic bucket for soaking, never steel, metal, or aluminum.
