Features

  • 6 Stage Home Water Filtration System: Max Water 6-stage RO-DI (reverse osmosis deionization system) filteres particles down to 1/10,000 of a micron effectively filter out 99.99% of impurities after DI (deionization) stage. This includes improvement against bad 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 filter out 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) after the DI stage.
  • TDS Note: After the DI stage, the TDS drops to 0, however your water output may still have a TDS value. This is a result of the final stage of filtering using an inline carbon filter. Any unfavourable taste or odour left behind will be eliminated by this inline carbon. It's possible that the process will leave behind small, harmless carbon particles (60 PPM/TDS), which will gradually filters.
  • 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.
  • Quality Tested: We consistently provide products and services that meet customer quality requirements.
  • Why Max Water: We have 15+ years of experience in water filtration industry providing solution with a smile to millions of families across North America. Make Max Water your solution to all your filtration needs.

  • Great so far!
Color: 6 Stage 100 GPD RODI System With Digital...
So far it’s working out great. Two small issues that were corrected after a little time trying to figure it out . The O ring for the to filter was not easy to place kept leaking till I figured out how it’s supposed to go . Second better instructions on hose assembly would be nice ( bigger pictures for older eyes). Printing very small as well as pictures. Other than that is fills a 5 gallon container in 57 minutes. That’s great. ... show more

  • Zero TDS
Color: 6 Stage 100 GPD RODI System
instruction booklet isn’t very self explanatory but overall easy to set up with the help of YouTube. After flushing according to instructions, my TDS meter was reading zero within 30 minutes. At 60 PSI this product was producing just about 3 gallons per hour which is slightly lower than advertised however it still fit my needs. I’m overall very satisfied. ... show more

  • Works well!
Color: 6 Stage 100 GPD RODI System
I purchased this unit for my aquarium. I use it about once a week to create water for my ATO I installed a T in the copper pipe and mounted this to it. Super easy if you have plumbing skills. if not, I think this could be very complicated Once installed, it has worked great. I can do about 30 gallons in eight hours. ... show more

Great filter but instructions are vague and the instructions show how to connect filter to 2 other devices i dont have , water pump and pressure switch which did not come with this 6 stage water filter. Better instructions are needed to install. I was able to get it done but I took off auto shut off valve and pressure gauge ... show more

  • Did the instructions get translated?
Color: 6 Stage 100 GPD RODI Hydroponics
It works. 3 stars because the instructions are terrible. The video installation is the only saving grace. Even still, the video and the instructions show nothing about the pressure gauge and where it goes as well as the teflon tape placements. Your main filter cap will require the tape or it will leak no matter what. Be sure to look up a guide on how to properly use the tape on the filter cap or you will spend hours cleaning up wet floor and disassembling/reassembling the unit. ... show more

  • Worked well for a year now!
Color: 6 Stage 100 GPD RODI System
I use this unit for my saltwater reef tank. A year later and I’ve done nothing but added a second DI canister. I added the second one so that I can refill them with cation and anion resins separately, since they don’t exhaust at the same time. A little better than the mixed bed, imo. Great unit. No complaints. Fits well under my bathroom sink! ... show more

  • Aquarium RO Water
Color: 6 Stage 100 GPD RODI Hydroponics
Very pleased with this product. Easy set-up with clear, concise directions. All filters and tubing are included and are of standard size so they will be easy to replace when necessary. You will need an adapter to hook up to a kitchen/bathroom sink. Everything else comes in the box. price is fair, too, for my dime. ... show more
