FAQ's about RO/DI Systems

Q) Does reverse osmosis remove parasites?

A) The largest allowable pass through in a reverse osmosis membrane is 1/10,000th of a micron. The
size suggested by the NSF to remove parasites is 1 micron. This makes the filtration quality of reverse
osmosis 10,000 times better than the recommended value!​

Q) Where does the TDS go after the RO removes it?

A) The RO membrane has the ability to clean itself. The particulates in the water are flushed down the
drain. This is why the RO membrane lasts so much longer than the other filters in the system.​

Q) How much water does this system waste?

A) The typical waste to product ratio for a reverse osmosis system is 4 to 1 under the correct pressure.
The ratio will change in favor of the product as the pressure increases. There are other ways to improve the waste to product ratio as well. Please call us at (877) 803-7462 if you would like to explore options to improve your waste to product ratio.​

Q) How important is water pressure to my system?

A) Water pressure is very important! Optimum pressure to run an RO system is 60 PSI. Anything below 40 PSI is too little pressure for the system to function correctly and will cause under production and over waste. Low pressure will also cause the membrane to clog much sooner. If your pressure is under 40 PSI you need to consider the addition of a booster pump.​

Q) How often should I change my prefilters?

A) It is suggested to change the prefilters every 6 mon ths. This frequency may vary depending on the quality of your source water. High levels of particulates and or chlorine in your source water would suggest a more frequent filter change routine. It is not suggested to exceed 6 months under any circumstances.​

Q) I have high iron, will this harm my system?

A) Iron is very hard on a membrane as it is one of a short list of substances that the membrane is unable to remove from its surface. If you know you have high iron, we suggest the addition of a water softener with with iron removal capabilities. This will remove the iron up to 2 ppm. Anything below this is not a concern as the membrane should last 2 years at this level.​

Q) Where do I find filter replacements for my system?

A) We carry a full line of filters for your system and they are available for purchase 24 hours a day on our website or you can call our sales office at (877) 803-7462. Our system filter sizes are industry standard and can be found in any store that carries water treatment products. However, our systems are supplied with extremely high quality, one micron or lower filters. They are industry standard size but better than standard quality. Any substitution if necessary, should be temporary.​
