Installation was done by a plumber because my pipes are in an old house and sizes are not modern standards. He did not use the plastic T but installed a brass one on my cold water feed. I bought EZ4 because it filters the best. Water flow is what I would expect for a drinking water faucet. The included faucet in my unit does not have the indicator light with battery and the listing said it did. I bought the unit in October and didn’t install till January so too late to exchange the unit. Would have been nice to have the indicator light to know when to change. All in all this unit is so much better than having a big filter stuck on my sink faucet and getting in the way. I’ve not changed the filter yet so I can’t speak to the ease of filter replacement. I would definitely recommend this system but also have someone with plumbing skills around to be sure you have the right fittings because not all house’s plumbing is modern and standard. Review: Don't be alarmed if the water tastes different...that's a good thing! - Fairly easy to install. I didn't have any leaks. Water comes out cloudy at first but then clears up as it settles (I guess from going through the filter media). Tastes a little different than before, but maybe that's because I'm used to the chlorine taste that it previously had and now it has no taste?. Overall, very satisfied. I did call tech support for a question on how far the tubing went into the culligan faucet (5/8 inch or all the way which is about 2 inches) because the manual wasn't clear here (just said to push 'firmly' into the faucet). The tech did not call back until the following day, but said it only goes in a short distance so the ferrule compression ring compresses on the tubing where the T insert is fitted into the end of the tubing. Makes sense to me...the insert gives it strength so the compression washer doesn't crush the tubing. I originally had the tubing pushed all the way into the faucet and still did not have a leak. Another thing I did was to cut a piece of 5/8 inch plywood to use as a template that I could hold firmly against the wall to drill the hole in a granite countertop for the faucet and to keep the bit from walking. I drilled a 5/8 inch hole (same size as the bit I was using to drill through the granite countertop) in the plywood where I wanted the hole and used it to guide the diamond coated bit to cut through the countertop. This worked perfectly. I kept dipping the diamond coated bit in water every 30 seconds to clean it and keep it cool. It only took about 5 minutes or so and I was through. Perfect clean cut. ## Features - SUPERIER FILTRATION: Provide your family with visibly clean, great-tasting water for drinking, cooking and more - FEATURES: Reduces particulates class 1, chloride, cyst, chloroform, MTBE, mercury, lead, turbidity, perfluorinated chemicals; 0.5 GPM flow rate; Includes 1 twist-on/off filter cartridge replacement, tubing, dedicated faucet, and installation hardware - COMPATIBILITY: Culligan US-EZ-4 cartridges - FILTER LIFE: Up to 6 months or 500 gallons, depending on usage and water conditions - CERTIFICATION: Tested and certified by IAPMO to NSF/ANSI Standard 42 for the aesthetic reduction of Chlorine Taste and Odor, Chloramines and Nominal Particulate Class 1.

Perfect clean cut. ### ⭐⭐⭐⭐ Filter is good, the included hardware isn't enough. *by B***E on September 30, 2023* I get it, products are made to a price point. But most of America has 3/8 compression fittings on their shutoff valves. The water tap that comes with this kit requires removal of your shutoff valve which means cutting off the water for the whole house. And it's a cheap fitting at that. Assume you will have to purchase something to connect you existing water supply to the included 1/4 line. And they don't really include much line, so might need to purchase more if your supply is at one side and you want to mount the faucet on the other side of the sink. Then there is the faucet. It feels really cheap. Compared to my last Ispring faucet this feels lower quality and the knob is awkward and can't be reversed due to a still way to mount the base. The biggest issue is if you have granite counters that are not paper thin, the nut to tighten the water line hits the retaining nut for the faucet. That was the filter itself is a beast and the mount is nice quality. They say you have to turn off the water supply to replace the filter but it seems like the type that doesn't need that. Will have to test it when it's time to change the filter. Overall not terrible but a little more thought should have gone into this. It's still the best filter that's not RO and has actual ratings on it for what it removes. --- ## 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.it/products/8369678-culligan-us-4-ez-change-under-sink-water-filtration-system](https://www.desertcart.it/products/8369678-culligan-us-4-ez-change-under-sink-water-filtration-system) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-08*
