Introducing the APEC ROTL-600 Tankless Reverse Osmosis System. Featuring a premium 3-stage filtration designed with high-quality materials to bring you the best tasting and purest water possible into your home. The first stage Sediment/Carbon filters out sand, silt, rust, and other unwanted larger impurities. Then the water flows to the second stage RO Filter membrane where 99.99% of impurities are removed. This is where the RO system removes impurities including heavy metals such as Lead, Arsenic, and Chromium, as well as harsh & harmful chemicals like Chlorine, Fluoride, PFAs (forever chemicals), as well as 1,000+ chemicals, metals, and pathogens. With an efficient pure-to-drain ratio of 1:1, you will enjoy less wasted water and money. Due to the tankless design, you do not need to sacrifice under-the-counter storage to have clean water! Keep your storage space below organized and neat. The ROTL-600 will indicate the status of your filters with illuminated lights informing you when a cartridge change is due or soon to be. We don’t take being the most trusted name in water purification for granted, we stand by our products and offer lifetime customer support with agents in the USA to assist you!
