• Quick Install & Anti-Clog Design: Push-to-connect fittings and a twist-and-lock design support DIY installation in about 3 minutes and filter replacement in about 3 seconds. The upgraded filtration area is described as providing about 20× more dirt-adhesion area to help improve filtration performance while reducing clogging risk. Includes a 3/8" line for standard under-sink feed valves plus a 3/8"–1/2" converter for common cold-water lines and faucets.
• Service Life, Applications & Notes: When used with municipal water, the system is rated for up to 12 months of use (actual life varies by water conditions) and can be upgraded with UF or MZ filters to match different needs. Suitable for kitchens, bathrooms, RVs, offices, and rentals due to its compact design. Note: TDS is not a complete indicator of water quality; the system is designed to retain minerals (such as calcium, potassium, sodium, and magnesium) while reducing certain unwanted substances, so TDS readings may not drop.
