Not all RO systems are created equal. Some are wimps. You need a tough customer for well water.
First, check for pre-filtration. Well water often carries sediment or sand. You need a sediment filter before the RO membrane, or the membrane gets clogged. It’s like putting on sunscreen before a beach trip. Do it.

Second, look for a booster pump. Well water pressure is low. Really low. RO systems need pressure to work. A booster pump is like a personal trainer for your water. It pushes it through the membrane with gym-level effort.
The sneaky problem: iron
Iron is the villain of well water. It turns your laundry orange and your tea black. It also destroys RO membranes.
You need a system that handles iron. Some RO units come with iron filter add-ons. It’s like giving your system a shield. Chlorine is also a membrane killer. If you use bleach in your well, make sure your RO has a carbon filter first.
Quirky fact: Some people’s well water is so iron-rich it looks like rusty lemonade. Don’t drink that. Get an RO system.
