Transform your tap water into pure, refreshing drinking water with the IPW Industries AC-30 Compatible Reverse Osmosis Filter Replacement Kit. This comprehensive annual maintenance package includes everything you need to keep your Culligan reverse osmosis system operating at peak performance: 2 sediment filters, 2 carbon block filters, and 1 inline GAC post-filter. Engineered with premium materials, our 5-micron sediment filters feature 100% polypropylene construction with a flat-bottom design that sits securely on your sump cup, effectively capturing rust, sand, and particles before they reach your RO membrane. The carbon block filters utilize high-grade coconut shell carbon to eliminate chlorine, chemicals, and unpleasant odors, ensuring your water tastes crisp and clean. The NSF-certified 2"x6" inline GAC filter provides final-stage polishing, removing any remaining tastes or odors after the reverse osmosis process. With convenient 3/8" quick-connect fittings, installation takes minutes without special tools or plumbing expertise. Compatible with Culligan models AC15, AC30, H83, H83S-R, and LC50, plus numerous OEM part numbers, these filters deliver OEM-quality performance at significant savings. Replace pre-filters every 6 months and the inline filter annually to maintain optimal flow rates and protect your investment. Note: RO membrane sold separately.
