Thank You so much 😊** A: Hello, The yellow light indicates that you have about 120 gallons of water left before reaching 1,000 gallons. This is a good time to order your replacement cartridge. Thank you, WaterChef Customer Care **Q: No green light after battery and cartridge replacement. Can someone help please?** A: I’ve had the same problem with two replacement cartridges and batteries. Have been replacing based on time since the lights don’t seem to work. **Q: Does the filter look different when used? After more than 1 year mine is still white and no lights blinking** A: Then you are lucky, you must have really good water. We have been using WaterChef under the sink filter for years now, and every time the red light blinking & we change the filter, it is a greyish color. You can definitely see the residue on it. **Q: The yellow and red lights flash a few times then go off. No green light. I'm replacing the filter. What does this mean?** A: That happens to me as well. When replacing the filter make sure you replace the battery that comes with it. For me after about six months I start seeing the red light flash again ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great filter that is actually certified. *by P***R on August 8, 2021* I have had the water chef filter for 3 years now, and I think it works great. One thing that got me to buy this is that it is actually certified. I checked on the certifications for other filters and they are not listed, but this one actually is on the NSF website. Beyond that, this was fairly easy to install initially and works well with no leaks. We have a new baby in the house and it is great to know that many of the metals and chemicals present in water are being filtered out for baby and mom. ### ⭐⭐⭐⭐⭐ Easy to install *by R***D on December 20, 2024* Healthy water, healthy life! Works perfectly and easy to install! ### ⭐⭐⭐⭐⭐ If you want a filter, this is unbeatable *by R***3 on April 16, 2019* Update 11/3/21: I just replaced my filters for the third time. This water filtration system is simply the best, in my opinion. Our water tastes great, is clear, clean and is great for the environment. We use thermal water bottles for take along, eliminating throw away plastic bottles. This system is a terrific value, and they have found a loyal customer. Original review: I bought this filter to replace all of the other filters I have tried over the years. Filters hanging on my faucet, or huge filter pitchers in my fridge or on my counter, replacement filters taking up space in my pantry. The cost of all that stuff really angered me. I started my search for an alternative. I found it with Water Chef. Under the counter installation that was so easy. Did it myself. The filter works for 1000 gallons. Our last two filters cartridges lasted for 14 months. This is our third. We are saving so much money and the water tastes great. No more worries about clean drinking water. ## Frequently Bought Together - WaterChef UR90 Undersink Filter Replacement Cartridge (for WaterChef U9000 Filter Systems) 1000 Gal.
