Our Experience with the CuZn Under Sink Water Filter
Great value for the money, this filter delivers a noticeable improvement in water taste and clarity.I was surprised by how clean the water felt after just a few days, and the absence of chlorine and metals like lead is a huge plus. The 5-year filtration life means I don't have to replace it often, which saves me time and hassle. The installation was straightforward-no drilling, and the included parts made it easy to set up under my sink.It's a solid choice if you want reliable, high-performance filtration without sacrificing beneficial minerals.
The three-stage system, with Micro Sediment Membranes, KDF-55, and Coconut Shell Carbon, effectively tackles contaminants like PFAs and PFOS. I've tested it against other filters, and the NSF/ANSI 42 and 372 certifications back up its claims. The result is water that feels smoother and tastes better than before. Though, it doesn't remove TDS, so if mineral content is a concern, you'll need a separate reverse osmosis system.it's also a bit heavier than some models, but that's a small trade-off for its durability.
it's a well-designed filter that outperforms competitors in longevity and performance. The DIY setup is a breeze, and the customer support was prompt when I had a quick question.If you're looking for a long-term solution to purify tap water, this one ticks all the boxes. Just keep in mind it's not a magic fix for TDS if that's critical for your needs.

The Key Contaminants We've Successfully Reduced
The CuZn under-sink filter is a game-changer for anyone seeking cleaner, better-tasting water. After installing it, I noticed a significant improvement in my tap water's flavor, thanks to its 3-stage filtration system-Micro Sediment Membranes, KDF-55, and Coconut shell Carbon.It effectively removes harmful contaminants like PFAS, PFOS, Lead, and Chlorine without stripping away essential minerals, which is a huge plus. The NSF/ANSI 42 and 372 certifications add peace of mind, confirming its performance and safety.Plus, the 5-year filtration life means fewer replacements and long-term savings compared to other filters that last just 6 months.
Installation was surprisingly simple. The inline design fits under my sink with no drilling required, and the included parts made setup a breeze. I watched the video tutorial, and it took less than 10 minutes. The filter's compact size is perfect for small spaces, and the water flow remains strong even after years of use. Though, it's vital to note that it doesn't reduce Total Dissolved Solids (TDS), so I still use a separate reverse osmosis system for complete purification.
Pros and cons are clear. The pros include: • 5-year filter life,• NSF/ANSI 42 & 372 certification,• No drilling installation,• Removes PFAS,PFOS,lead,and Chlorine,• Maintains beneficial minerals,• Improved taste.

A Long-Term Solution for our Water Needs
I recently installed this under-sink water filter, and it's transformed my tap water experience.

My tap now tastes almost like bottled water,with a noticeable reduction in chlorine and lead. The NSF/ANSI 42 and 372 certifications give me confidence in its performance, especially for tackling pfas and PFOA/PFOS, which I'd heard were tough to remove.
Installation was surprisingly simple. No drilling required, and all parts are included.The video tutorial made it easy to set up in under 10 minutes, even for someone like me who's not DIY-savvy. It's compact enough to fit under most sinks,and the low-maintenance design has been a breeze. Plus, the 5-year filtration life is a huge plus-far better than the mere 6 months other filters offer.
