    I’ve been using the Omnipure K2555 DI post-filter after my RO system for a few weeks now, and I’m truly impressed. It delivers amazingly crisp, ultra-pure water—perfect for brewing coffee, aquariums, and lab-quality tasks. The filter efficiently drops the TDS to near zero with zero taste or odor. Installation was a breeze thanks to standard quick-connect fittings. A bit pricier than standard carbon filters, but the purity and consistency are absolutely worth it. Highly recommended for anyone seeking top-tier water quality!
