My pick for the absolute best value is the APEC Essence RO-90. It’s the upgrade to the Budget Bro, with a 90-gallon-per-day capacity and a four-stage filtration that’s so smooth, Jesus would use it if he were a plumber. It installs in about 30 minutes, even for a person who thinks a wrench is a type of sandwich. The taste? So clean that your ice cubes will try to apologize for tasting like freezer burn.
One more shocking fact: a typical RO system uses about 3 gallons of waste water for every 1 gallon of clean water. That sounds terrible until you realize your washing machine wastes 27 gallons per load and your toilet could water a small jungle. Plus, you can repurpose the “waste” water for your plants—they won’t spill the tea on your slightly bougie filtration flex.
The Unofficial Checklist
Before you click “buy,” ask yourself: Do I have a faucet that isn’t from 1985? Do you mind a small filter under the sink that looks like a robot colon? Is your water pressure above 40 psi? If your water pressure is lower than your enthusiasm for Mondays, you’ll need a booster pump. That’s a whole other rabbit hole, but trust me, it’s worth it to avoid waiting an hour for a glass of water.

Also, remember that RO systems aren’t cheap long-term. You’ll need to swap filters every 6 to 12 months, which costs about $50 to $100 a year. That’s less than what you’d spend on bottled water in a month, but more than a bag of avocados. Priorities, people.
