This system is best suited for water that has moderate hardness (below 15 grains per gallon) and certain chemical properties, which may not cater effectively to all water sources.

The initial installation is electric-powered and requires setup at the home’s water entry point, which might necessitate professional assistance for some homeowners.

This system is best suited for homes with moderate hardness in water and may not be effective for those with higher levels of hardness, as it doesn't soften water or remove minerals that contribute to hardness. Additionally, while it significantly reduces contaminants, it does not lower Total Dissolved Solids (TDS), which might be a consideration for users concerned about mineral content in their drinking water. Another aspect to consider is the installation process, as it requires setup at the home’s water line point of entry, which may necessitate professional help for those who are not handy with plumbing.
