Hands On Review: 5 Stage Reverse Osmosis Water Filter by Reverse Osmosis Revolution – Dial in Your Home Brewing Water!


Why Use a Reverse Osmosis Filter for Homebrewing?

Using RO (Reverse Osmosis) or DI (Deionized) water allows you to start with a clean slate of sorts and build your water profile from the ground up using water salts.  That allows you to take control of an important aspect of your brewing, especially if you’re an all grain brewer and create exactly the water profile you’re looking for.

Water by John Palmer and Colin Kaminski, part of the Brewing Elements Series, is a great read to learn lots more about brewing water and water adjustments

Hands On Review

cln_img_12491st stage: Premium Quick-Connect 5 micron sediment filter. Dust and rust particles are trapped here in a filter which also extends the life of the system and the membrane.cln_img_12472nd stage: Premium Quick-Connect T28 coconut activated carbon filter – VOCs (volatile organic compounds) and other common chemicals are removed from the water in this stage. This filter also removes chlorine, cloudiness, offensive odors, colors and unpleasant tastes.cln_img_12543rd stage: High Rejection TFC type reverse osmosis membrane. 95%-99% of total dissolved solids (TDS) and other elements are removed in this stage. Arsenic, fluoride, lead, chromium, radium, viruses, bacteria, and other unhealthy contaminants are removed from the water. 75 gallon per day capacity. Made in USA.
4th stage: Produces ultra high quality water with deionizing mixed bed polishing filters. This stage produces exceptionally clean water with a minimum TOC backgroundcln_img_12455th stage: Premium US made T33 post polishing filter.

Note that you do need to use this filter on a regular basis.  According to the manufacturer (via email) you can extend that time by placing the unused assembly in the refrigerator.  After an extended period of non-use you are supposed to flush the filters for a set amount of time.  Consult the manual for guidelines.  If filtered water has an odor, according to the manufacturer (via email), you should replace the filters. Along with brewing water, I’m planning to use this for drinking water as well.  Check with manufacturer for current filter replacement guidelines.cln_img_1242The complete unit.  The top two hoses are for incoming water and waste water.  The bottom (unconnected) tubing is an option for outgoing pure, filtered water.  The other option is an included spout.  I went with the tubing option.cln_img_1260Here’s a look at the spout along with some additional replacement fittings that are included.cln_img_1262I swapped out the spout base for the hose option.  This is where filtered water leaves the assembly.cln_img_1264By default, this comes with a chrome metal 2-way diverter for kitchen faucets.   It’s said to fit 96% of all kitchen faucets (female or male type of spout). If you want to connect to garden/laundry hose, specify in the customer’s notes – see product description for more/current information on that.  Since I’m using this with a utility sink, I did want the garden hose option.  I used the “Contact Seller” feature to contact the seller, after placing an order, to let them know about my hose connection preference.  I found this to be a little tight getting on.  Better too tight than too loose.cln_img_1267The directions say to flush this for one hour prior to using the water.  From the first stuff that came out… I’d say that’s a good idea.cln_img_1270I picked up a TDS (Total Dissolved Solids) [Model TDS-EZ] meter to test the effectiveness of the filter.  If you decide to start purchasing RO or DI water from the store (instead of getting a filter), I would still suggest picking up a TDS meter.  Some water processors add minerals back for flavor.  A TDS meter will allow you to make sure you’re getting what you want.cln_img_1275Back of the package and instructions.cln_img_1286Front with cap removedcln_img_1279Back of the metercln_img_1308I used two Rubbermaid 1 gallon pitchers [Review] to measure how quickly pure and waste water were being produced.  It took about 3 minutes to produce 1 quart of waste water.  That’s about 5 gallons per hour.  It took just under 5 minutes to produce 1 quart of pure water.  The figures to 20 minutes per gallon or 3 gallons per hour.  That matches specifications right on.  Maybe even a little more quickly.  I’m not sure if this varies based on water quality of if it varies over time.  I’m very happy with how quickly this produces pure water.cln_img_1363My untreated tap water read 249 PPM (parts per million).  I used my Perfect Beaker [Review] to collect samples.cln_img_1303After being filtered, I got a reading of… 1 PPM!cln_img_1305The waste water came in at 382 PPM.  Note: You can collect waste water and use it for purposes other than brewing water.cln_img_1357Collecting brewing water in a 7 Gallon Aqua-Tainer Drinking Water Jug.


I can tell you empirically (because of the meter) that this filter works really well.  It took my hard tap water down to 1 PPM.  It’s easy to use and fits my situation perfectly.  I really like that it can be hooked up as I need it and it produces water relatively quickly.  Along using this water for brewing and drinking water you can also use it mix up Star San and resolve issues related to cloudy Star San [See: Testing Star San Effectiveness].

    So I have a question regarding waste water. According to my math and your numbers, in 60 minutes this system will produce 3 gallons of clean water and 5 gallons of waster water for a total of 8 gallons of water.

    Is this correct?
