We have copper pipes and get green stains if drips in bath tubs, showing copper in our water. Also they treat the water with fluorides here.

I want to filter both and I understand a reverse osmosis filter is best for doimg this. Anyone research this and have found a good one? Any regrets to the one you got over others?

While these filter systems are great! As a plumbing contractor I've "never" found a consumer maintain these systems correctly. The different filters, membrane and storage tank all have specific requirements on maintenance and replacement. Filters need replacing every 6 to 9 months. The membrane need to be replace every 2 to 3 years. And the storage tank needs to be pressurized and checked and replaced 2 or 3 times during the life of the system. Then there are other parts that fail too.

For my tenants I like a simple single filter system, like an Ever-pure sealed cartridge.

We have well water, a little hard, but lots of dissolved iron. I actually prefer hard water, probably because I grew up with it. Soft water feels too slimy to me, I doesn't feel like the soap is rinsed. We have 2 particle filters first, since we get a black silt in the water too. Then the iron filter, which needs little maintenance. It back washes every few days and the media needs changing every 10 - 12 years. That makes the water fine for most uses except drinking. It still has a funny taste. For a long time we used a brita filter pitcher and that worked, we talked about putting one under the sink and DH got an Reverse Osmosis. Not a full house, just for drinking.

My daughter has a different type of iron, it actually comes out of the sink clear, but in 5 minutes the iron precipitates and it looks like it came from a mud puddle. She just uses a softener with iron salt in it. That works well for her.

We installed our RO filter in the basement under the kitchen sink since it would have taken a lot of cabinet space. We are happy with the RO filter. But it does waste 2 - 3 gallons of water to every 1 gallon it filters. And that is the most efficient one. Not too concerned for amount used for drinking, coffee and tea. We still cook with the faucet water. Not sure I would want to do RO with a whole house. I am sure just a carbon filter under sink would have worked just as well for us.

We have a water softener in the garage, be sure it is separate from irrigation water or you will salt your plants.

We also have a ro purifier on the kitchen sink. Our water here is horrible, so it makes a big difference. Some people do whole house ro, but I don't feel it necessary.

We have another filter in the refrigerator but just fill water bottles from the ro and cool them.
