SpiroPure SP-RO400AQD 150 GPD RO DI Water Filter System for Aquariums, Reefs; 4-Stage Apartment RO Countertop Reverse Osmosis System with Deionization, Tankless
Brand: SpiroPure
Read more
- 4-STAGE RO SYSTEM: SED sediment filter reduces large particles to protect the other cartridges. The CB carbon filter utilizes coconut shell solid block activated carbon to protect the RO membrane from harsh chlorine and other chemicals. The RO reverse osmosis membrane reduces harmful particulates and impurities in water down to 0.0001 micron, including total dissolved solids (TDS), heavy metals, sodium chloride, copper, chromium, lead, and more. The final stage is a DI deionization filter.
- DEIONIZATION FILTRATION: Fourth stage DI cartridge employs mixed-bed, indicator resin for enhanced filtration of TDS (total dissolved solids). A 2:3 ratio of cation and anion resins assists in near complete reduction of ions from water including sodium, sulfate, copper, and more. Color-changing green media turns purple when exhausted, letting you know it’s time for a cartridge changeout. Deionization filtration produces pure water faster, more efficiently, and more affordably than distillation.
- HIGH FLOW: Unlike other reverse osmosis systems, SpiroPure countertop RO systems come with a high-flow 150 GPD membrane, the highest water flow rate that can be currently achieved at this RO membrane cartridge size.
- VERSATILE INSTALL: This portable RO water filter with deionization can be wall-mounted or placed upon your countertop, making it a great choice for aquariums or Apartment RO applications. Get practically purified water for your aquarium, spot free-cleaning for cars, streak-free cleaning for windows and other glass, CPAP machines, humidifiers, neti-pots, and more.
- EASY INSTALL: This RO system comes mostly pre-assembled to save time, not only with pre-installed mourning brackets, but each filter cartridge already has the quick-connect fittings for easier installation. Color-coded hoses help you in knowing which line goes to what port. The package also includes wall mount brackets and screws, as well as two faucet adapters (3/4" standard garden hose connections and 1/2" connections for select kitchen faucets).
