FAQS About Reverse Osmosis Water Filter Systems
What is a Reverse Osmosis Water Filter?
A reverse osmosis water filter is an advanced water purification system that removes contaminants on a molecular level. Unlike basic carbon filters, reverse osmosis systems force water through a semi-permeable membrane with microscopic pores that block harmful substances while letting water molecules pass through. These systems use multiple filtration stages—pre-filters to eliminate sediment and chlorine, the main reverse osmosis membrane for impurity removal, and post-filters to polish the water. The result is highly purified drinking water free from contaminants like lead, arsenic, fluoride, pesticides, and many other chemicals that standard filters can’t remove.
How Does a Reverse Osmosis Water Filter Work?
A reverse osmosis water filter works through a multi-stage purification process that begins when water enters the system from your home’s supply line.
- In the first stage, water passes through pre-filters that eliminate larger particles, sediment, chlorine, and organic compounds that could damage the sensitive reverse osmosis membrane.
- Next, the water is forced under pressure through the reverse osmosis membrane—the core of the system—where water molecules pass through while contaminants are blocked and sent to the drain.
- After passing through the membrane, the purified water flows into a storage tank until you need it.
- When you turn on the dedicated drinking water faucet, the stored water passes through a final polishing filter that removes any lingering taste or odour before it reaches your glass.
This thorough process results in water that is up to 99% free of dissolved solids, heavy metals, microorganisms, and other unwanted substances.
What Size Reverse Osmosis Water Filter Do I Need?
The size of your reverse osmosis water filter depends on your household size and daily water consumption. Smaller households (1-3 people) usually do well with systems that produce 50 gallons per day, which is enough for drinking and cooking. Medium-sized households (4-6 people) typically benefit from systems rated for 75-100 gallons per day, while larger homes or those with higher water use might require commercial-grade reverse osmosis systems that can produce 150+ gallons daily.
During the initial consultation, Mersey Heating and Air Conditioning technicians will recommend a system that ensures you have enough purified water without unnecessary waste or capacity you’re paying for but not using.
