Hydronix HX-ICF-2512-ALK Alkaline Remineralization & Ph Inline Water Filter Fits Any Ro Drinking Systems, 1/4 inch Npt Ports, White

These filters are not cheap, but are the highest quality inline re-mineralizing filters that I could find on this platform. Not only does it provide a complete spectrum of minerals and electrolytes (ionized calcium, magnesium, sodiumand potassium), it uses high-quality Bio Ceramic media to achieve this, which you can't say about most of even the bigger brands selling a similar product on Amazon.Most cheap alkaline filters are mostly filled with some kind of cheap charcoal/carbon substrate and industrial-grade calcium that shouldn't even be used for drinking water. The multi-stage media in this filter include:• D600 Anti-oxidant Mineral Spheres• Bio Ceramic Alkalizer• ORP Mineral Stones• D300 Alkalizing Bio Tablets• Mineral BallsThe only gripe I have with this particular offering is the 1/4" NPT interface. I would prefer quick-connect fittings so that you don't need extra adapters/sealant to incorporate this into your RO stack.

I have installed it to my RO System which is quite easy. It increased the water quality. I would have given 5 star rating but I am not sure about its life cycle (durability ) since I installed couple months back.

No fittings
