About This COMPLETE FILTER KIT FOR YOUR NORTH STAR NSRO42C4: This OEM replacement set includes everything your system needs for a full annual maintenance — the 7287514 reverse osmo sis membrane (1–3 year life) plus the NSROPF4 pre and post filter set (replace every 6-12 months). AUTHENTIC NORTH STAR OEM PARTS — NSF CERTIFIED: Every component is genuine North Star Water Treatment Systems-manufactured and NSF certified for performance and safety. The membrane is certified to reduce chlorine taste and odor and meets NSF/ANSI standards for contaminant reduction. OEM parts fit correctly, perform as designed, and protect your system’s warranty. FITS NORTH STAR NSRO42C4 ONLY — PLEASE VERIFY YOUR MODEL: This filter set is designed exclusively for the North Star NSRO42C4 reverse osmosis system. It does not fit other North Star models or other brands. Check your system’s model number before ordering. Not sure? Message us and we’ll confirm the right filters for your system before you buy. IMPORTANT UPDATE — BATTERY NOT INCLUDED IN CURRENT VERSION: The previous filter set (7287506) included a battery for the system’s filter change indicator. The current NSROPF4 version does not include a battery — this is a manufacturer change, not a missing item. If your filter change indicator needs a new battery, standard replacement batteries are available separately. Everything else is identical in quality and fit. INCLUDES FILTER CHANGE REMINDER TAG — NEVER MISS A CHANGE: Every kit ships with a Soft Water Supply branded reminder tag — record your installation date and next change due date right on the tag and hang it on your system. Pre/post filters: replace every 6-12 months. Membrane: replace every 1–3 years. Sold by Soft Water Supply, an authorized water treatment parts distributor.
