iSpring FA15 Alkaline Inline Water Filter Cartridge, 10” x 2” with 1/4” Quick Connect, NSF Certified, Add-on for RO Systems, Balances pH & Restores Minerals, 3-Layer Replacement Filter

Good

Awful water taste (bad fish) i flushed my whole system like 5 times and every time the smell goes after flushing and comes back after water settles for a few minutes in the filter . I’ve noticed a couple of reviews here mentioning the same issue, it would be great if the vendor can explain what’s happening here and whether its a product defect or something. I had to throw this 3 days after hours and hours of flushing/wasting water

This filter gives an horrible after taste, tastes like plastic and not pleasant. Have wanted a few weeks to see if it goes away and run many liters of water through it but no improvement.

Llevo varios años con esta marca de filtros y no defrauda . El cartucho de filtro iSpring FA15 ha sido una gran mejora para mi sistema de filtración de agua. Se nota la diferencia en el sabor, eliminando cualquier rastro de cloro y dando un agua más fresca y limpia. La instalación es sencilla y el rendimiento es excelente. Dura bastante tiempo antes de necesitar reemplazo, lo que lo hace una opción conveniente y económica. Además, su compatibilidad con sistemas iSpring lo hace ideal para mantener una filtración de calidad. Si buscas un filtro que realmente haga la diferencia en la pureza y el sabor del agua, este es una gran elección.

This filter is good and will buy again

I use a sediment cartridge, carbon cartridge, ro membrane and dionizer resin bed filter with this Alkaline and mineral filter and its been working great. I use the rodi system for my reef tank, but since rodi water is essentially stripped of everything bad and good things, I could not use it for drinking purposes, so I bought this filter to remineralize the water and it did. the rodi water had 0.01 tds, and after running it through the alkaline filter, it went up to 0.14 which means I have minerals again essential minerals. The Ph was already pretty good at 7.6-7.8 but after running it through the alkaline filter it went up to 8.8-9.0, and as you may or may not know alkaline water is great for you as apposed to acidic water, and since your body is made up of mostly water it makes sense, anyway iam rambling here, so to wrap up I am very happy with the results.

Tip 1: Flow arrow is a clear engraving and easy to miss. Don't rely on the sticker label orientation in comparison to the video, which some say can be reversed. Tip 2: My TDS went from about 10-15 (iirc) to about 50-65 (My tap is 400TDS). Perfect for me. This TDS tastes great to me. EDIT: placing in front of tank, TDS dropped to 30-35. Not sure if this will cause scaling in the tank though. Tip 3: Took me about 1 minute to install. It's easy if you know how to release the quick connect. I did it in-line to the tank for now, but understanding there's maybe a few oz in the cartridge that will sit and overmineralize. I'll move it to before the tank if it bothers us as it does for some others. EDIT: I've heard of 3 different ways in the reviews to install this alkaline cartridge lol. The 3rd way is after tank but before polisher. Just different tradeoffs. No one has provided an argument for which is definitively best.
