💧 6 Stage Home Water Filtration System: Max Water 6-stage RO-DI (reverse osmosis deionization system) removes particles down to 1/10,000 of a micron effectively removing 99.99% of impurities after DI (deionization) stage. This includes reduction in bad tastes and odors, lead, fluoride, copper, cysts (cryptosporidium, giardia, entamoeba & toxoplasm) and other metallic ions from water leaving you with clean, clear water. 💧 Safe Aquarium Use: A RO/DI system removes contaminants from tap water, making it safe for use in your aquarium fish tank. When it comes to water filtration, you're going to either have an RO or RO/DI system. An RO and RO/DI are almost identical except the RO/DI system has an extra filtration stage called the "DI or Deionization" stage which brings the water down to 0 TDS (total dissolved solids). 💧 Simplified Installation: Our systems are designed to help installing and maintaining them easier. Quick Connects are color coded to make knowing how to install the system quick and easy. All filter housings are labeled for easy filter replacement. 💧 BPA free components: Our RODI water filter system doesn't contain Bisphenol A or other toxic plastic materials. 💧 Quality Tested: We consistently provide products and services that meet customer quality requirements. Producing 99.99% pure water, this is a great system if you are looking for a reverse osmosis unit for your saltwater aquarium or hydroponics setup.
