Kind Regards Mia Lauren　 Customer Service Rep ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent product *by on Reviewed in the United States July 24, 2024* I bought this as my backup for my filtration system. I have used the system for over a year now and the first filter actually lasted 10 months. I was thrilled as the information had said it should last about a year. The water here is well water and has a high concentration of calcium. The Waterdrop system and filters have consistently filtered water with TDS at 100+ to TDS at 30-40 during that 10 months of daily usage. I admit to using the system to provide drinking water and water for tea and coffee only. I highly recommend the system and filters. ### ⭐⭐⭐⭐⭐ Countertop water cooler filter *by on Reviewed in the United States February 23, 2026* It’s perfect.
