I added this filter kit to my express water system and my ph has now been raised to 7.8 - 8.0 ph. Easy install and compatibility with my express system. Well worth the money as it was half the cost of express brand! ### ⭐⭐⭐⭐⭐ Good tasting water *by K***E on August 12, 2025* Easy to install improves taste of water and is a good price ### ⭐ LEAKY FILTER GROWS MOLD!!! *by W***W on September 17, 2022* The filter was easy enough to install (I liked that it came with quick connect fittings for both 1/4 and 3/8 tubing), but the low quality plastic of the fittings against the low quality plastic of the filter meant that one or both pieces’ threads bent out of shape upon the first gentle test-fit I did. So, I wrapped the threads well, using premium (Oatey) Teflon pipe tape, cut my filter-to-spout tube, and re-assembled the filter between the two freshly-cut pieces of tubing. All seemed fine and I flushed for 15-20 minutes as directed, and the water tasted pretty good. HOWEVER, the good things end there. Over the next few days, every time I went to use the filtered water, it would spurt and purge the air from the line, as if I had just put it in. And if air is getting in…… that means water was getting out. Out of the filter assembly, which sits in my sink-adjacent kitchen cabinet… made of wood. I redid the Quick connections, ensuring cuts were 90°, i removed and re-applied more Teflon tape to the threaded parts, I silicone’d around the threaded connection points, and gingerly put it all in the cabinet with a drip pan underneath. Fast forward another two days, and the water started spurting again and now had a funky taste. I pulled out the drip pan with the filters, and noticed MOLDY GROWTH AMONG THE FILTER MEDIA, which I’ve shown in the attached pictures, along with large air bubbles!!!!! I immediately shut off the water to the filter system and cut the filter out. Geekpure’s customer support did nothing. ## Frequently Bought Together - Geekpure 10 Inch Inline Alkaline Water Filter Kit pH+ for Reverse Osmosis System -1/4” Port - Geekpure 5 Stage Reverse Osmosis Replacement Filter Set with 50 GPD Membrane -Standard 10 Inch --- ## 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.uk/products/170902049-10-inch-alkaline-ph-water-filter-kit-2-x-10](https://www.desertcart.co.uk/products/170902049-10-inch-alkaline-ph-water-filter-kit-2-x-10) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-10-18*
