How to Choose the Best Reverse Osmosis System

If you want clean drinking water for your home without relying on a water delivery service or bottled water, the best reverse osmosis systems can offer great tasting water on demand! We found 10 amazing osmosis systems for people who want to improve the taste of their drinking water, reduce plastic waste, and reduce contaminants in their water. Before we get into the reverse osmosis reviews, here are some important features to know about while shopping for your new system!

Best Reverse Osmosis Systems

Filter Capacity: Under the sink reverse osmosis systems come with a storage tank that reserves clean water for whenever you’re ready to use it. Whole house systems won’t have a tank – instead, they hook right into your water main for constant filtration.

Product Buying Icon

Contaminant Removal: One major benefit to reverse osmosis systems is their ability to remove several contaminants from your drinking water. This may include things like microorganisms, metals, sediment, fluoride, etc. Removing these contaminants improves the overall look and taste of your water.

How to Choose the Best Reverse Osmosis System

Flow Rate: The flow rate for your system is the amount of clean water it outputs. This is expressed by gallons per day or gallons per minute. You can use this to help you choose the right size for your family’s needs!

Product Buying Icon

Stages: Reverse osmosis filtration systems use a series of different filters to cleanse your water of a variety of contaminants. More stages mean a wider variety of contaminants are filtered out, but it also means more filters to change and maintain.

Best Reverse Osmosis Systems

Size: Under-sink filtration systems are great for those who want clean drinking water without installing a giant tank and system. We’ll let you know the size of each one so you can find one that fits perfectly under your kitchen sink!

Product Intro Icon

Warranty: Investing in the best reverse osmosis system you can afford will keep you outfitted with clean drinking water for years. However, if something bad happens to your system, a warranty will protect you and help with repairs or parts replacements.

Now that we’ve covered everything you need to know about reverse osmosis systems, let’s get to the fun part – product reviews!
