Frequently Asked Questions

A reverse osmosis system uses multi-stage filtration — including a membrane — to remove up to 99% of contaminants like lead, chlorine, fluoride, nitrates, and more from your water.

What does an RO system remove?
 RO systems remove:

  • Heavy metals (like lead, mercury, arsenic)
  • Chlorine and chloramine
  • Fluoride
  • Sediment, rust, and dirt
  • Nitrates, sulfates, and more
  • Bad taste and odour

Most systems require:

  • Pre-filters: every 6–12 months
  • Membrane: every 2–3 years
  • Post-filters: every 12 months
    (Your system’s manual will have exact timelines.)

Modern RO systems are much more efficient than older ones. Some high-efficiency models use as little as 1 gallon of waste per 1 gallon of filtered water.

Many under-sink RO systems are designed for easy DIY installation and include all parts. If you’re not comfortable installing it, a plumber or handyman can typically do it in under an hour.

Yes — reverse osmosis removes most minerals. However, this does not make the water unhealthy. You can add a remineralization filter if preferred.

It depends on your water quality. RO systems remove more contaminants than standard carbon filters, making them ideal for those wanting the cleanest water possible.
