Thanks for trying our Elite Filter, and we're sorry to hear that it's not the right product for your household. While we think you get the best of both worlds when filtering with our products, improved taste, and reduced contaminants, we don't make claims about TDS reduction at Brita. TDS isn't a measurement of water safety, and here at Brita, we focus on what we think matters most to people: contaminant removal and taste. We'd love to discuss this with you more, so please call 800-242-7482 and mention the reference number 231220-000176. We hope to talk to you soon. Shannon from The Brita Team
