Water filtration systems improve the taste, the smell, and the appearance of your tap water, all while removing dangerous contaminants that may cause health issues. Operating from Austin, Texas, Aquasana, Inc is a reputable company that creates its products with the environment in mind. That’s why all of its water filter components are engineered with recyclable parts, compostable materials, and produce minimal waste.

Until a few years ago, reverse osmosis water filters were not all that ideal because while they did filter out the bad contaminants, they also filtered out the good minerals. However, Aquasana resolved this issue with the launch of the Aquasana OptimH2O Reverse Osmosis + Claryum. This NSF-certified system is the first of its kind to combine powerful reverse osmosis filtration with Claryum selective filtration and remineralization, so while it effectively removes harmful contaminants, it replenishes your water with healthy, essential minerals.

Key Features of the OptimH2O Reverse Osmosis + Claryum

This Aquasana is NSF certified to standards 42, 53, 58, 401, and P473 and is packed with key features. The reverse osmosis system enables the filter to remove fluoride plus 88 other contaminants to ensure the healthiest, safest drinking water. The secret that makes this filter so effective is that the water pressure pushes the water through a special membrane that captures contaminants and impurities, which are then flushed down the drain. The innovative technology features remove the pollutants without removing healthy minerals like magnesium, calcium, and potassium.

The filtration and remineralization involve six unique stages, which all work together to provide the cleanest, purest water available.

  1. Reverse Osmosis: Filters out the dissolved solids smaller than one micron, such as fluoride and arsenic.
  2. Activated Carbon: Reduces chemicals such as herbicides, pesticides, MTBF, and VOCs.
  3. Catalytic Carbon: Eliminates chlorine and chloramines.
  4. Ion Exchange: Filters heavy metals such as lead and mercury.
  5. Absolute Sub-Micron Filtration: Tackles asbestos and cysts like giardia and cryptosporidium.
  6. Remineralization: Replenishes with healthy minerals such as calcium, magnesium, and potassium to improve the pH balance and alkalinity.

The impressively fast flow rate of 0.5 GOM and produces up to 32 gallons of water daily.  The operating pressure of 40-100 psi is effective.

The Pure Performance easy filter replacement is eco-friendly Claryum and carbon, so twisting it off and replacing it is simple and can be done within seconds.

 While the design may not be the most important factor to consider since most water filters are out of sight, it is worth mentioning that the OptimH2O Reverse Osmosis + Claryum is a larger filter at 12” X 4.5” x 12.5,” (length x width x height),  and the tank is 16” x 11” (height x diameter). It will fit under your sink, but you may not have much remaining room. However, most customers still refer to this system as “compact.”

What does this Water Filter remove?

The OptimH2O Reverse Osmosis + Claryum has been tested and proven to remove five times more contaminants than other reserve osmosis systems. Typically, other RO systems remove just 5-15 contaminants, while this filter removes 88! The OptimH2O Reverse Osmosis + Claryum has been proven to remove:

  • 95% fluoride and mercury
  • 97% chlorine and arsenic
  • 99% lead and asbestos

For a complete list of contaminants that this filter removes, see the Performance Data Sheet.
