The following lists some advantages to using this filtration system.

Potent Water Filtration System

The CDC considers powerful reverse osmosis filtration as highly effective in removing bacteria. This is exactly what Aquasana RO uses. Tap water first passes into a more concentrated solution to remove contaminants. The pore size that reverse osmosis water filters use is about 0.0001 micron. The next stage is to go through a diluted solution filtered by a semi-permeable membrane for more cleansing.

Patented Claryum Technology

Because of the claryum RO filter, product owners can enjoy safe and great-tasting water. The technology filters out at least 74 contaminants. You won’t be taking chlorine or heavy metals with your drinking water. The OptimH2O also removes chloramines and chemicals that are used on plants or pests. There’s more.

It retains the naturally-occurring minerals that are beneficial. Your drinking water keeps its magnesium and potassium content. The pH maintains balance. Also, alkaline and calcium magnesium and potassium content are intact.

NSF Tested

Similar to Aquasana Clean Water Machine, the Optimh2o reverse osmosis claryum filtration is NSF tested. The California Department of Health Services Drinking Water Treatment Device Program tested it. Results certify that it meets the standards for safety and quality. Each glass of water is safe for those with sensitive stomachs.

Quick Water Filtration

Aquasana’s OptimumH2O water filtration cleanses your tap water fairly fast. The estimated rate is .5 gallons per minute. That’s good enough for four glass servings in one minute.
