The difference is night and day! I'd got so used to drinking flat-tasting tea, coffee and straight water, that the introduction of this filter is immediately apparent. Straight water or cordial is especially tasty now. Installation was easy, just insert the 1/4" product water pipe straight into the filter without any additional connections and you're laughing. Now that I know, I will not do without one of these in future.

The water tastes a lot sweeter than normal and very refreshing. According to the description it adds magnesium sodium potassium and calcium so a health benefit too. So much like drinking spring / mineral water so saves pounds in buying such. Highly recommended and a vast improvement on normal filtered water. ## Frequently Bought Together - Waterdrop Remineralization Under Sink Water Filtration, 1/4” Quick Connect Post Filter for RO Reverse Osmosis Filter System, Restore Essential Minerals - Waterdrop G3P600 Reverse Osmosis System, 8 Stage Tankless Reverse Osmosis Water Filter, NSF/ANSI 42 & 58 & 372 Certified, Under Sink RO System, 2:1 Pure to Drain, Smart LED Faucet - Waterdrop G3 Replacement Filter 1-Year Combo, Pack of 2 WD-G3-CF Filters and 1 WD-G3-CB Filter, Replacement for WD-G3-W, WD-G3P600 and WD-G3P800-W Reverse Osmosis System --- ## 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.jp/products/373621966-waterdrop-remineralization-inline-water-filter-1-4-quick-connect-post](https://www.desertcart.jp/products/373621966-waterdrop-remineralization-inline-water-filter-1-4-quick-connect-post) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-06-18*
