The right size size for my water cooler Thanks a bunch πŸ’œ Review: Excellent product - 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. ## Features - The K19RF replacement filter is compatible with Waterdrop 𝐖𝐃-πŠπŸπŸ—-𝐒, 𝐖𝐃-πŠπŸπŸ—-𝐇 countertop reverse osmosis system. - [Superior Filtration Performance] The innovative RO membrane is designed to reduce TDS, chromium, PFAS, fluoride, arsenic salt, iron, radium nitrate, calcium, particles, chloride, chlorine and heavy metals. - [0.0001ΞΌm Pore Size] The superior RO membrane of the filter can intercept any impurities larger than 0.0001 micron.
