With one of the highest purity and production ratings, the Microline® removes up to 93% of virtually all impurities, delivering great-tasting, healthy water every time*.

Frequently Asked Questions

What contaminants can a reverse osmosis (RO) system remove, and how does it improve my water?

An RO system can remove up to 99% of common contaminants like lead, chlorine, nitrates, arsenic, and sediment, along with many other dissolved solids. By using a semipermeable membrane, it filters out even tiny particles, giving you water that’s cleaner, clearer, better-tasting, and safer to drink.

Can RO systems be used for both city water and private well water?

Yes, RO works well for both. On city water, it removes chlorine, chloramines, and other treatment byproducts. On well water, we often recommend a UV + RO combo to also address bacteria or microorganisms. We’ll test your water to match you with the right system.

How often do I need to change filters, and is this included with your plans?

Most RO filters are replaced every 6–12 months, while the membrane lasts 2–5 years. With our rental and maintenance plans, all filter changes and servicing are included, so you don’t have to track schedules or handle replacements yourself.

Will an RO system reduce water pressure or waste a lot of water?

Modern RO systems maintain good water flow and are more efficient than older models. While some water is used during filtration, newer designs minimize waste to just a few gallons for each gallon of purified water produced.

How does RO compare to bottled water?

RO is more cost-effective and convenient than bottled water, giving you unlimited fresh water at home without the plastic waste. Many customers save hundreds each year while reducing their environmental footprint.
