But I didn't fully realize all the plastic you throw away with the filter cartridge until after a year when I replaced the stage 1&2 filters. Wish the manufacturer would try to reduce throw-away plastics.... ### ⭐ poor product *by A***R on January 25, 2021* Do not buy! If you do verify the waste water. The one I had wasted over 10 to 1. If you buy do it thru Amazon and if not happy you can return it. My experience with auqusure indicates you might have to jump thru hoops to return. ## Frequently Bought Together - Aquasure Reverse Osmosis Water Purification System, 4-Stage Filtration, NSF Certified, Polypropylene Material, Multicolor - Aquasure Harmony Series 48,000 Grains Whole House Water Softener w/High Efficiency Digital Metered Control Head (48,000 Grains) --- ## 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.vn/products/92685941-reverse-osmosis-water-purification-system-4-stage-filtration-nsf-certified](https://www.desertcart.vn/products/92685941-reverse-osmosis-water-purification-system-4-stage-filtration-nsf-certified) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-10-09*
