Frequently Asked Questions

What is a whole-house reverse osmosis system?

A whole-house reverse osmosis system purifies all the water entering your home, not just one faucet. Water is forced through a fine semipermeable membrane that removes up to 99% of dissolved contaminants, so every tap, shower, and appliance delivers clean, purified water. It is one of the most thorough home water treatment options available.

When do I need whole-house RO instead of a water softener?

Choose whole-house reverse osmosis when your water has problems a softener alone cannot fix, such as arsenic, nitrates, high total dissolved solids, or several contaminants at once. A softener removes hardness minerals, while RO removes a far broader range of dissolved substances. Free in-home water testing helps confirm which solution your home actually needs.

Does whole-house reverse osmosis remove arsenic from well water in Northern Minnesota?

Yes. Whole-house reverse osmosis removes arsenic along with lead, nitrates, fluoride, and other dissolved contaminants, cutting up to 99% of total dissolved solids. Arsenic occurs naturally in some Northern Minnesota groundwater, so well owners with severe or complex water chemistry often choose whole-house RO for complete, every-tap protection.

What Hellenbrand whole-house RO systems does Range Water Conditioning install in Northern Minnesota?

Range Water Conditioning is a factory-authorized Hellenbrand dealer offering the N Series and the HRO 3.5 whole-house reverse osmosis systems. As a high-end whole-house solution, these can be paired with pre-treatment such as softening and iron removal. All Hellenbrand equipment is built in the USA.

How is whole-house RO different from an under-sink reverse osmosis system?

Whole-house reverse osmosis treats every water line in your home, while an under-sink system purifies water at a single faucet. Whole-house RO is the higher-end choice for households with severely contaminated water, sensitive skin, or health concerns who want purified water from every shower, tap, and appliance, not only for drinking and cooking.

Is whole-house reverse osmosis worth the higher cost?

For homes with severe or complex water problems, whole-house reverse osmosis is often worth the investment because it protects your family, plumbing, and appliances throughout the home. It is a premium solution best suited to water that softening alone cannot resolve. A water test confirms whether contaminant levels justify the upgrade.
