Know before you buy
The system includes a dedicated calcium mineral cartridge that adds calcium back into the water after the reverse osmosis process. This safely raises the pH level, resulting in water that is more alkaline and often described as having a smoother, more refreshing taste.
The system features super-capacity filters designed to last twice as long as standard filters. Depending on your local water quality and usage, you can generally expect to replace the pre-filters every 6 to 12 months and the membrane and mineral cartridges every 2 to 3 years.
With dimensions of 18 inches high, 16 inches wide, and 5.25 inches deep, the unit is designed to fit most standard under-sink cabinets. We recommend measuring your available space, including the area occupied by your garbage disposal or existing plumbing, before installation.
The RO-PH90 is WQA Gold Seal certified to remove up to 99% of common impurities. This includes lead, chlorine, heavy metals, cysts, sediment, and various pesticides, ensuring your drinking water meets high safety standards.
Yes, this system uses a storage tank to hold the purified water, as the reverse osmosis process happens at a slower rate than a standard faucet flow. The 90 GPD rating refers to the daily production capacity of the membrane, ensuring you have a steady supply of water ready when you need it.
While many homeowners with basic plumbing knowledge choose to install the system themselves, it does require connecting to your cold water line and drilling a hole for the dedicated drinking water faucet. If you are not comfortable working with plumbing, hiring a professional plumber is recommended to ensure all connections are secure.
