FAQS About Reverse Osmosis Water Filter Systems
What is a Reverse Osmosis Water Filter?
A reverse osmosis water filter is a comprehensive filtration solution that purifies water at the molecular level. Unlike standard carbon filters, reverse osmosis systems force water through a semi-permeable membrane with tiny pores that trap contaminants while allowing pure water to pass. Each system includes several stages of filtration—pre-filters that capture sediment and chlorine, a main RO membrane, and final filters that enhance taste. The outcome is extremely pure water, free from common contaminants like fluoride, lead, pesticides, and more.
How Does a Reverse Osmosis Water Filter Work?
Reverse osmosis water filters clean your water through a staged process that starts as soon as water enters the unit from your home’s plumbing system.
- Initially, water flows through pre-filters that remove particles, sediment, chlorine, and chemicals that could damage the RO membrane.
- It then moves to the semi-permeable membrane, where pressure pushes water molecules through, while impurities are rejected and flushed away.
- The clean water is stored in a built-in tank until needed.
- When you turn on the system’s designated tap, the water is routed through a final carbon filter that removes any lingering odours or taste, delivering a refreshing glass every time.
This process removes up to 99% of total dissolved solids and contaminants, including bacteria, heavy metals, and more.
What Size Reverse Osmosis Water Filter Do I Need?
The right system size depends on your household’s water use and the number of people in your home. A 50-gallon-per-day system works well for households of 1–3 people. For medium homes (4–6 people), a 75-100 gallon-per-day system is more appropriate. Larger families or those with high water demands may require a commercial-grade unit delivering 150+ gallons per day.
During your in-home consultation, M&K Heating and Air Conditioning will recommend a system that meets your needs, providing enough filtered water without wasting energy or space.
