Review: Excellent so far - Perfect but little on pricey side to other options. I wanted something to add to my 6 stage RO system which comes out at zero for my reef tanks. As I now live in a very hard water area with no reservoirs the water smells and is awful up this way. Added this to the side to which I divert the water for drinking. Comes out at around TDS 82 perfect and even better with a slice of fruit. Review: Goodness you can taste. - This is our second time using the iSpring & there is a noticeable taste profile difference which highlights a difference in quality between a cheaper brand. If it didn't make a difference we would buy a cheaper brand. Lasted the stipulated time, water still tasted good. Just replaced it as it had hit the 12 month period. Obviously different water quality will impact its longevity. Water is back to fresh spring tasting perfection. Installation is easy. turn tank off, open faucet, disconnect old filter insert new one, turn tank back on, run water through it, test it with TDS meter, enjoy. No mess, no fuss straightforward. Soft in the mouth like water from a fresh spring on a long hike. Refreshing like in Psalm 23. ## Features - BALANCED MINERALIZATION - Standard RO systems remove both harmful pollutants and beneficial minerals, often producing slightly acidic water.

While I think we're not meant rely on our drinking water to get our minerals, sometimes I get questions of concern from guests. Word to the wise: best not to even mention that your water filter is RO. Sometimes people think it's distilled water. Ugh. Anyway, I bought and attached this sixth alkaline stage and did a before and after taste test. The 'before' was just as good as ever. The 'after', now going through the filter, has a slight brightness to it which, while not a huge difference, is to my taste buds preferable. ## Frequently Bought Together - 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 - iSpring F7-GAC NSF Certified 1-Year Replacement Filter Cartridge Pack, 7-Count for Standard 5-Stage Reverse Osmosis (RO) Systems - iSpring Greatwell Reverse Osmosis Membrane 75 GPD 11.75” X 1.75”, Replacement Fits Standard Under Sink RO Drinking Water Filtration System, MC7 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.ke/products/48699655-fa15-alkaline-inline-water-filter-cartridge-nsf-certified](https://www.desertcart.co.ke/products/48699655-fa15-alkaline-inline-water-filter-cartridge-nsf-certified) --- *Product available on Desertcart Kenya* *Store origin: KE* *Last updated: 2026-09-18*
