Deionization White No gauge

Purity Defined

Our combination of Reverse Osmosis and Deionization creates the ideal home system for the purest water possible. The four stages of filtration before Deionization dramatically increase the lifespan of your filter and gives you a lower cost than Deionization alone. Great for softening hard water at your point of use without adding sodium. Start making better tasting food, ice, coffee, and drinks. Extend the life of your water using appliances by keeping impurities out of them!

White gauge deionization

  • Express Water’s 1st stage is a Sediment filter that targets dirt, dust, sand, and rust.
  • The 2nd and 3rd stages are Granular Activated Carbon and Activated Carbon Block Filters which focus on pollutants like chlorine, volatile organic chemicals, and odor causing compounds.
  • These early stages help extend the life of the 4th stage, the Reverse Osmosis Membrane. The membrane focuses on the most difficult impurities like lead, arsenic, chromium, fluoride, TDS, radium and others.
  • The 5th stage is the Deionization Filter. Deionization filters even the finest dissolved impurities and most difficult minerals via ion exchange. The RO Membrane extends the life of your DI Filter.
  • The 6th stage is a Post Activated Carbon Filter which does a final pass on your water, right before it comes through the faucet, removing any possible taste or odor.

It’s the combination of these stages that has given countless customers water purer than bottled water straight from their faucet.

NSF certified tested performance

Independently Tested

Express Water RO Systems have been independently tested by a third-party ANAB accredited testing laboratory that use established NSF / ANSI drinking water standards, including NSF/ANSI Standards 42, 58, 401 and EPA 524.2, for the reduction of TDS (total dissolved solids), chlorine taste & odors, emerging compound and incidental impurities, and more.

  • Heavy Metals: >99.96% (Including Mercury, Lead, Uranium, Chromium VI and more)
  • Chemical Disinfectants: 99.68% (Chlorine and Chloramine)
  • Fluoride: 99.83%
  • Pharmaceuticals: >99.99% (Including Testosterone, Ibuprofen, Caffeine and more)
  • Nitrates / Nitrites: 99.26%
  • Volatile Organic Compounds (VOCs): >99.99% (Sources include paint, varnishes, gasoline, smoke and more)
  • Semi-Volatiles: >99.29% (Including hydrocarbons, ethers, PCBs and more)

    Skip the Deionizer and Could use a membrane flush valve

    Skip the Deionizer and Could use a membrane flush valve
    This kit gives you a lot of features for the price, but I would recommend this kit instead: https://www.amazon.com/dp/B00J2DGTD8/ref=emc_b_5_tI'll explain why below.First of all, I really like this kit. This kit came with everything you'd need for a standard install. It does have an automatic shutoff when the reservoir is full, which is a key feature since these things can generate about 300 gallons of waste water a day without that shutoff valve. Second, this has two stages of carbon filtration before the RO membrane. It takes some digging as to why this is good, but ultimately this is for chloramine treated water which a lot of cities use as it's more stable than chlorine. This stability means it's also harder to remove, hence the need for multiple carbon stages. I'm not 100% sure what the third carbon stage adds other than a nice-to-have and being a post-membrane scrubber may remove some undesirable chemicals that may leach from there. All-in-all, I don't hate the third stage of carbon, but I don't know if I'd have gone out of my way to add one but it is a nice feature that I'm glad to have.The two things I'd change about this kit is: First, I'd add a membrane flush valve. This allows you to "bypass" the RO membrane and only generate wastewater. This is key when you replace your first two stages of carbon, and is a good preventative maintenance step to do periodically which prolongs the life of your RO membrane. You can buy this separately for about $10 and would be a good investment. Still not a deal breaker, I really do like this RO unit (note, not the DI unit).The reason why I'd recommend the other kit is because I strongly recommend you skip this deionizer. If you don't need a deionizer, don't waste your money. This adds not only about $30 to the filter cost, but also adds about $80 a year in filter media ($40 per filter replacement every 6 months). From what I can tell it's an integrated dual-media filter that needs to be replaced if either media becomes expended. It's difficult to see if/when you need to replace the media (not a clear container using color-change media) and the replacement media is very expensive. For about $100 you can pick up a two-stage deionizer, with a standalone (In/Out) TDS meter, color changing media to tell you when to replace the media, two separate deionizing media that can be replaced only when they are expended, and the media only costs about $15 per canister per replacement ($30 per complete replacement) and should last twice as long. This upgrade should easily pay for itself in the first year. Additionally, the additional TDS meter will let you know when the input TDS creeps up indicating a membrane failure. It's cheaper to replace a failed $17 membrane than to destroy $30 worth of media only to then replace both. This feature will save you about $20 on the first membrane replacement.All-in-all, fantastic kit. You get a lot for the price and the quality seems fantastic, but I'd go with the other kit by the same manufacturer, and pay a little extra up-front for a dedicated, two-state, color-change, DI filter.

    Reviewed in the United States on December 25, 2020
    So I'm not much of a handyman, and anyone who's seen my reviews in the past will know this, but this system was very easy to install, works flawlessly, and provides us some of the best water we've ever tasted. Took me about 2 hours to install, and the only reason I have given it less than a perfect rating is because the cheap water faucet they provided has already begun leaking and replacing it will be around 70 bucks. Other than that, this unit is superb and I'd by another.
