Pure, Healthy Water From Your Faucet
Start drinking healthy and stop drinking impurities with your own home Reverse Osmosis Water Purification. Express Water offers the highest impurity reduction rated RO Membrane for up to 99% reduction of major water impurities.
We have designed our system’s four stages of filtration to work together for long-lasting high-grade impurity filtration, giving you the cleanest water and the best value in filtration.
Choose the best in home filtration and start drinking healthy today!
- Express Water’s 1st stage is a Sediment Filter that targets dirt, dust, sand, and rust.
- The 2nd stage is a Granular Activated Carbon Filter which focuses on pollutants like chlorine, volatile organic chemicals, and odor-causing compounds.
- These early stages help extend the life of the 3rd stage, the Reverse Osmosis Membrane. The membrane focuses on the most difficult impurities like lead, arsenic, chromium, fluoride, TDS, radium and others.
- The 4th 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.
Independently Tested
Express Water under sink 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)

There was a problem filtering reviews right now. Please try again later.
My first attempt at cleaning up my water was a Brita pitcher. It did absolutely nothing to improve water texture or taste, but it may have been effective in filtering various unwanted particles, etc.
My second attempt was a PūR faucet filter. Again, it did nothing regarding improvement of taste or texture. I did however like the convenience of the faucet attachment, and I was impressed with the amount of potentially harmful elements the manufacturer claimed it could remove.
My third attempt was a Zerowater pitcher. Wow! This was the first time my tap water ever tasted as good as bottled water. I'm not sure how each of the three mentioned filters compare concerning the removal of harmful contaminants, but I do know that the Zerowater filter produced the best tasting water. Using the included TDS (total dissolved solids) meter, Zerowater delivered a zero reading just as promised.
If Zerowater is perfect, then why am I here discussing an Express Water system? The expected lifespan of Zerowater filters is dependant on initial water quality. My TDS rating of 575 means that I would only get 8 gallons or less per filter. Even when buying filters in a bulk pack it would be MUCH more expensive than buying bottled water. It's simply NOT cost effective.
Finally, my last and best solution: An EXPRESS WATER countertop Reverse Osmosis system.
The Express Water system is incredibly easy to install. A simple to understand instruction sheet is included. (1) Remove the blue lock pins from the connector on the SED filter and also from the connector on the black hose coming from the ROM filter. (2) Pull out the protective pins, insert the two color coded hoses (that lead to the faucet connector), and then put the blue lock pins back on. (3) Attach the faucet connector and you're ready to go! It took me about 10 minutes to set everything up.
It's recommended to let the water run through the filter for roughly two hours before you'll achieve the best quality.
My results:
Express Water fills a 64oz (half gallon) bottle in 13 minutes. One gallon in 26 minutes. It reduces my 575 TDS rated water to a rating of 9 and delivers water that has a very pleasing texture and taste.
* Your results may vary depending on water pressure and quality.
How I use it:
I fill a couple of 64oz bottles with filtered water and keep them in the fridge. I also still use the Zerowater pitcher. The water going into the pitcher now has a TDS rating of 9, so the Zerowater filters last much longer (40 gallons or more) and the filtering process is much faster.
No more carrying multiple bottles of water home from the store each week, and I feel better about not generating so much plastic waste.
If you live in an area with a relatively mild TDS rating, the Zerowater pitcher may be all that you need. But, the only cost effective solution for those in areas with a high TDS rating is to use a Reverse Osmosis system. The Express Water is one of the least expensive to buy, maintain, and operate.
I highly recommend the Express Water countertop system.
Special Notes:
Make sure the faucet attachment is correctly on the threads and tight. If too much water is leaking you'll reduce water pressure and end up wasting water.
Even though the overall build quality is excellent, my ROM filter is leaking (directly under the large side of the filter on the left). Initially it was losing about a drop or two a minute, which adds up quickly. I was able to turn the large portion of the filter clockwise which stopped part of the leaking (now it's a few drops an hour). I'm going to give Express Water customer service a call to see if I can get it resolved. I'll update this review after I go through that process.
Some people claim that it's not healthy to drink water with a low TDS rating. In my opinion that's nonsense. You don't have to suffer with foul hard water taste and a heavy texture just to get minerals and nutrients in your diet, you'll get plenty from other sources. Plus, there are simple methods to add minerals back into the water should you wish to.
Keep in mind that the process of Reverse Osmosis generates a lot of waste water. It isn't like a pitcher or faucet filter system that only outputs clean, filtered water. With Reverse Osmosis you have a special faucet that outputs purified water, and at the same time you have another outlet that rejects the "bad water". For every one gallon of filtered water you're going to create a few gallons of "bad water". Probably a 3:1 ratio. You CAN collect the bad water and use it for watering plants, cleaning floors, etc. But it definitely should not be consumed. You may need to consider the extra usage of water in a Reverse Osmosis system if you have concerns about your overall water usage / water bill.
If you plan on using filtered water in an aquarium the manual recommends that you add the DEIONIZATION filter upgrade.
Required water pressure: Minimum 45 PSI / maximum 80 PSI. If your water pressure is too high you can add a pressure regulator to make it work.
Beyond the brands that I mentioned, there are many other very effective pitcher filter systems available. Some do an amazing job of removing very specific elements (like Floride) and some remove a broad range. Most are incredibly expensive to maintain and in most cases they don't reduce TDS levels (which may not be an issue for you). My advice is to research the quality of your tap water and decide what is most important for you to remove. Then seek out the filter system that best suits your needs.
PROS:
* Easy to setup!
* Very effective. I get a 3 ppm on the filtered water. Bottled water I used to buy was 5 ppm.
* Express Water support is very responsive, they usually responded my emails in about 8 working hours.
* Easy to extend with a hose with the EW "upgrade kit" (this is also a con, see below).
CONS:
* Wastes a lot of water, that should go without saying.
* After I first set it up I had an issue with the ROM filter leaking water. I contacted Express Water via email and they instructed me to "tighten" the filter head in order to stop the leak and it did (I used my hands to do it).
* I'm torn on value for money.. monetarily speaking is not the best compared to alternatives available in my neck of the woods. I will need to use this filter for a couple of years to see a _monetary_ return on investment. However, I was aware of this before buying and I still bought it mostly for convenience and peace of mind since you can't really trust the people that distribute the bottled water around here. I had somewhat of a health scare with one of the jugs the company sold me which prompted me to seek out alternatives like this RO system... but I digress.
* Stated filter life expectancy. Express Water should be more forthcoming/honest when it comes to the filter's life expectancy. Saying that the filters need to be replaced every 6 to 12 months makes zero sense. A family of 5 will make a much more intensive use of the RO system than a single person household and saying that they both need to replace the filters after the same amount of time is not very honest imho. Instead they should provide an estimation based on filtered gallons per day, assuming that the tap water has a certain PPM range. That would be way more useful, accurate and honest.
* In my opinion, the little metal spout is not the best approach for many use cases. Even to fill a small 1 gallon jug you still need to get a funnel or risk making a mess. The system should include some kind of alternative setup where we could fit a hose instead, or on top of, the spout.

Installation was easy on the kitchen faucet using the included adapter. Worked without any leakage from the faucet. Water tastes great, similar to bottled or from ZeroWater filter. Water flow rate is as expected from a RO system, very satisfactory. There's also no Deionizing Filter meaning the < 10 ppm water comes directly from RO membrane, shows good quality.
One small issue I had:
I noticed a small leak at the ROM filter cap (a drop every 2 secs). I tried to take the ROM filter out and tighten its cap using the included key. It did tighten it very well, however, when I tried to reconnect the pipes back together, the mouth of the ROM cap was now facing a different direction causing the white tubing to fall short to secure a connection to the GAC or PAC filter. So I contacted ExpressWater, explained the issue and asked for additional white tubing. They responded in time and mailed me additional white tubing for no extra cost. I was easily able to connect the tightened ROM filter now by cutting the required length of white tubing. There were no leaks at all after that.
