Product Overview
This mineral purifier cartridge (23434A), marketed by Leisure Time as an EPA-registered antimicrobial device, uses silver ions — derived from a silver chloride source — to help reduce bacteria levels in spa water. Designed to last 4 months or until your next refill, this cartridge works in spas up to 600 gallons, providing long-lasting, low-effort protection.
When used alongside standard sanitizers — chlorine, bromine, ozone, or non-chlorine oxidizers — it allows for up to a 50% reduction in chemical usage while helping maintain water clarity and balance; it's designed to supplement a minimal sanitizer residual, not replace sanitizer entirely. For water care convenience, simply drop it in the filter, skimmer well, or use a string for easy retrieval — no measuring or dosing required. It also helps maintain neutral pH and balanced chemistry, enhances filter performance, reduces maintenance time, and delivers softer spa water with less odor. It's suitable for all spa systems — chlorine, bromine, saltwater, mineral, and ozone — and its reduced chemical consumption makes it simple to replace and gentler on the environment than sanitizer-only water care.
