Experience and familiarity with the OmniFilter product line.

Great system I am replacing an old one that I have had too long. Tried other brands and they just do not work as good.
Diane L on Jun 30, 2015
Great Product
Richard P on Jun 30, 2015
I had one for 9 years when it developed problems so I tried to replace it with a DuPont Version which was a big mistake. The new Dupont version does not have the pressure to fill the Ice Maker and is constantly discharging waste water more than what the Omni Filter system ever did. I only replaced the Omni system because I wanted a simpler way to change filters. Even with the filter changes its still a better RO System

How often do you need to change filters and how many filters need to be changed?
A shopper on Mar 18, 2014
Can this unit be hooked directly to a refrigerator water line?
A shopper on Feb 28, 2015
Best Answer: Yes. If your not going to use the faucet that came with it just hook the water supply to ice maker line. The line for the discharge would then go to your sink drain st the highest point possible. When you look at the instructions, the reason the waste line connects to the bottom of the faucet and then to the drain is for an air gap so if your drain ever backed up dirty water good not be get back into the R O unit. And that could only happen if you lost water pressure at the same time. Better to install the faucet and tee off the filtered water supply to your ice maker.
Sorry do long winded, wanted to make sure y'all are completely informed. Good luck. Unit works great.

are there any retail stores in Omaha Nebraska that carry Omnifilter reverse osmosis systems? What is the most populare RO system for a small family? If I locate the tank and filters in the basement 20 feet from the dispensing faucet, will I have adequate pressure?
john n on Nov 18, 2014
Best Answer: I have installed the RO2050 with nearly 20 feet of tubing from the basement to the kitchen sink. The 1/4 inch tubing on the RO2050 does not deliver as much flow as the system I replaced that had 3/8 tubing throughout, but flow is reasonably good. The old system was three stages vs. the RO2050 five stages, which along with price attracted my attention.

I would never put the RO2050 under the sink because it has a lot of different tubing connections that will be cumbersome to deal with when it comes time to change the various cartridges. The previous system did not have any tubing connections to deal with when replacing cartridges, but I still chose to place it in the basement to avoid spills under the sink when changing cartridges. After 2 months all seems to be functioning well with the RO2050 and basement placement will make cartridge replacement much easier.

Be sure to understand how to depress the sleeve around the tubing connection so that you know how to release the various tubes when you change cartridges. Practice this while making the initial installation. Also be sure to firmly seat the tubes in each coupling. You will soon know which ones you didn’t do properly when you turn on the water! This connection system is becoming quite popular for all sorts of tubing and pipe connections.

What is the expected cost of filter replacement per year for a family of three?
john n on Nov 18, 2014
Best Answer: I can't answer this, as I bought this for our AZ home, and haven't installed it yet.

This is the web site for it: www omnifilters. com /ro2050- filter.htm

I had to add spaces because I can't put a website directly

You will find a place to ask the company directly.

Why is it better to connect to a non-softened cold water line? IF my whole house is on a softener sysyem, that is a lot of extra work.
Eileen M on Apr 24, 2014
Best Answer: You don't want the filter to treat softened water because it is full of salt. The main water line from your source (municipal or well) will be "hard" water. It will be the incoming water line to the water softener. Typically, a house is plumbed to have the cold "hard" water line run to the kitchen sink. You can trace the water supply line from its entry into your house or have a plumber determine if the cold water line to your kitchen sink is "hard". (Or just taste the water and determine if it is salty). The outside water faucets should definitely be plumbed "hard". If they aren't, your putting salt water in your garden and on your lawn!

How often does the filter need to be changed?
Jody J on Mar 18, 2014
Best Answer: Jody,

There are 4 different filters and they are changed at different intervals based on your water quality and consumption. Generally speaking though, the sediment filter RS14 changes every 4-6 months, the carbon cartridge CB1 every 6-12 months, the R200 finial filter every 12 months and the OM1 reverse osmosis membrane every 24 months. If you have very hard water and it is a municipal source heavily treated with chlorine and fluoride, the filter change intervals will be more often. I pretreat all the water entering my house with a whole house filter before it enters the RO unit or my water softener. Make sure you connect the RO unit to a NON-softened cold water line.

Hope that helps!

How much water goes down the drain during the regeneration cycle and how often does the system regenerate?
AllanG on May 11, 2014
Best Answer: The system only re-genterates the volume of water when water is drawn. Therefore, if you draw a pint of water the system will clean a pint of water to replace the pint drawn. Research indicates that the amount of waste water will depend on the quality of water going into the unit. For marginal tap water it could take up to seven units of waste water to produce one unit of purified water.

is a air gap required?
Bogart L on Apr 3, 2014
Best Answer: No need to modify. Just install as directed. The faucet supplied is an air gap faucet.
I hope this helps?

Does this filter reduce fluoride? By how much? Thanks
A shopper on Mar 18, 2014
Best Answer: Reverse Osmosis system can remove 87% to 93% of the Fluoride found in water. This would also be true of our RO2050-S-S06 system as well.

where is product manufactured ?
A shopper on Nov 6, 2013
Best Answer: Not 100% sure. Omni Filters is based out of Wisconsin, but being the RO business myself for many years, I'm sure most of the product if not all is made in China. This should not be an issue as Asia and Japan have been ahead of the US in this technology. The system performs flawlessly. I have purchased and used systems that cost 10 times this one, and there is no difference. Don't be afraid to purchase this item and be assured of safe drinking water.
