One membrane runs a Stealth-RO150; the RO300 uses two. As a membrane ages its rejection rate drops, so keeping an eye on PPM and swapping it in good time keeps your reservoir water genuinely clean rather than just filtered.\u003c\/p\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUp to 98%+ PPM rejection\u003c\/strong\u003e when new\u003c\/li\u003e\n\u003cli\u003eRated up to \u003cstrong\u003e150 gallons per day\u003c\/strong\u003e output\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect fit\u003c\/strong\u003e for Stealth-RO150, Stealth-RO300 and Stealth 100\/200 systems\u003c\/li\u003e\n\u003cli\u003eOutput scales with source water temperature -- warmer water gives closer to full rated output\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFalling RO output or rising PPM readings?\u003c\/h3\u003e\u003cp\u003eA tired membrane shows up two ways: the rejection percentage (how much of the inlet water's PPM it removes) drops below around 90%, or output flow slows noticeably. Testing your RO and source water PPM side by side tells you which stage needs attention -- if rejection has fallen off, it's the membrane, not the pre-filters.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFits Stealth-RO150 (1 membrane) and Stealth-RO300 (2 membranes)\u003c\/li\u003e\n\u003cli\u003eReplace every \u003cstrong\u003e6 months to 2 years\u003c\/strong\u003e depending on use and source water quality\u003c\/li\u003e\n\u003cli\u003eCheck rejection % periodically by comparing source and RO output PPM readings\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Stealth-RO150, Stealth-RO300, Stealth 100\/200 systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRejection rate:\u003c\/strong\u003e up to 98%+ when new\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated output:\u003c\/strong\u003e up to 150 GPD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity needed:\u003c\/strong\u003e 1 for RO150, 2 for RO300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTypical service life:\u003c\/strong\u003e 6 months to 2 years\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Hydro-Logic","offers":[{"title":"Default Title","offer_id":53798910492938,"sku":"NUT-HYD2-008-01","price":108.35,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/hydrologic-stealth-ro150-300-membrane-1.png?v=1790169707","url":"https:\/\/hydrocropshop.co.uk\/products\/hydrologic-stealth-ro150-300-membrane","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
