Northstar Reverse Osmosis Filter Set - Contains Membrane 7287514 and New Pre and Post Filter Set NSROPF4 (Replacement for set 7287506) with Maintenance Reminder Tag - Authentic NorthStar OEM

Time to replace the filters in your North Star NSRO42C4 reverse osmosis system? This complete OEM kit has everything your system needs for a full system filter change — in one order. What’s included: — 7287514 Reverse Osmosis Membrane (recommended life: 1–3 years) — NSROPF4 Pre/Post Filter Set — 2 filters (replace every 6 months) — Soft Water Supply Filter Change Reminder Tag Important note on the battery: The previous version of this filter set (part number 7287506) included a battery for the system’s filter change indicator. The current NSROPF4 version does not include a battery — this is a change made by the manufacturer, not a missing item. The filter components are virtually identical in quality and fit. If your filter indicator needs a replacement battery, standard batteries are available separately. The pre and post filters need replacing every 6-12 months — so this kit in many circumstances covers a full 12 months of maintenance. The membrane is included to complete your annual service. Order once, stay covered all year, unless your water quality requires more frequent filter changes. Why OEM matters: Third-party RO filters are made to generic tolerances and may not seat correctly in your NSRO42C4 housing, leading to leaks, bypassed water, or reduced contaminant rejection. Authentic North Star OEM parts are engineered for your system and NSF certified for performance and safety.
