Hear from people who love Aquasana
We moved into a house with a water softener and the water tasted terrible. One of our first purchases was this filter. Our water tastes fantastic! The flow is great too! We had a different filter at our old house and the flow of water was very slow! This one is great!
JEN S. - PENNSYLVANIA
I absolutely my RO system under my sink! It was very easy to install, and after letting it run for a little bit, the water already tastes better! I have city water so it completely changed the game for us to have this filter.
CRUNCHY MOM ENTHUSIAST
Installation was easy and water tastes amazing. Feels good to know my family is drinking clean water.
CHRISTYNM
We are loving everything about it! Was easy to install and we have had no issues with performance. The filtration is noticeably different that our previous filtration system.
SM123 - SAN DIEGO, CA
We love our RO water! It was pretty easy to install overall and the water tastes great. I especially like knowing that the water is remineralized. The spout matches our sink and faucet perfectly!
ERICA H
We're very well pleased with the Aquasana Smart Flow. We had it professionally installed so the work was done quickly by a plumber familiar with the product. After the initial preparation of the system, we quickly noticed our water, coffee and tea tasted better and that the occasional unpleasant smell we've experienced has not recurred. We also use the filtered water to wash fruits and vegetables. The brushed nickel matches our existing faucet, and the system is compact enough so that we still have adequate under-sink storage.

Enjoy Healthier, Better-Tasting Water with Aquasana Reverse Osmosis Water Filters

Aquasana reverse osmosis systems deliver advanced under sink water filtration for cleaner, healthier, better-tasting water straight from your tap. Powered by Claryum® + RO technology, our RO filters reduce significantly more contaminants than standard pitcher filters, including PFAS*, fluoride, lead, chlorine, and microplastics. Our RO systems are tested and certified to NSF/ANSI Standards 42, 53, 58, 372, and 401.

Compared to bottled water and pitcher filters, Aquasana RO systems provide long-lasting performance while helping reduce single-use plastic waste and freeing up valuable fridge and counter space. Each of our RO systems replaces the equivalent of thousands of plastic water bottles every year, helping reduce waste while providing clean, great-tasting water at a fraction of the cost.

Why Choose a Reverse Osmosis Water Filter?

Reverse osmosis water filters provide one of the most advanced forms of home water filtration available. They work by forcing water through an ultra-fine membrane that blocks hard-to-tackle contaminants that even carbon filters can't reliably catch.

Aquasana reverse osmosis systems combine powerful RO membrane technology with Claryum® filtration to reduce up to 99.99% of 90 contaminants, including PFAS* Forever Chemicals, fluoride, lead, chlorine, arsenic, pesticides, microplastics, and more.

Unlike pitcher filters, our reverse osmosis systems connect directly to your water line to deliver continuous flow of filtered water — no waiting or refilling required. Cleaner water on demand for drinking, cooking, coffee, and more.

The Power of Claryum® + Reverse Osmosis

Standard RO systems are effective, but they have trade-offs. They can be slow and waste significant water during the filtration process.

Aquasana addresses these limitations by combining advanced reverse osmosis filtration with our Claryum® technology. Our RO systems are designed to deliver faster flow rates, improved water efficiency, and exceptional contaminant reduction compared to traditional reverse osmosis systems.

The result is cleaner, great-tasting water you can trust for drinking, cooking, and everyday hydration.

Choose the Best Reverse Osmosis System for Your Home

Each Aquasana reverse osmosis filter is tailored to meet specific needs. Here's a quick comparison of our RO systems:

  • SmartFlow® Reverse Osmosis: Removes up to 99.99% of 90 contaminants. Combines three stages of filtration including Claryum®, reverse osmosis, and SmartFlow® technology for maximum performance and efficiency.
  • HealthShield™ Reverse Osmosis: Removes up to 99.9% of 85 contaminants. Combines two stages of filtration including Claryum® and reverse osmosis, while featuring a tankless design to maximize valuable under sink space.

Straightforward Installation and Easy Maintenance

Replacements will vary in frequency depending on the use and the system purchased.
