FAQ
Curious about how the RO filter works? Our FAQ section covers everything from filter lifespan to installation tips for clean, pure water every day.
Why more and more people are choosing RO water
The most common reason people choose a reverse osmosis system is to reduce contaminants in drinking water. Regardless of your geographical area, there is more than basic H2O in your tap water, and an undersink or countertop reverse osmosis system can dramatically reduce unwanted contaminants. But most people don’t know how RO systems work, the benefits of RO water, or how to choose a suitable reverse osmosis system. You can read our blogs to learn more about water-related information.
How does a reverse osmosis water filter system work?
Water first goes through a pre-sediment PP membrane and a carbon block filter, which is where contaminants like sand, rust, chlorine, and others are reduced. After running through another sediment membrane to remove even more impurities, the water is subjected to a multi-stage composite filter design with a reverse osmosis system — reverse osmosis membrane. This step reduces 90% of TDS and heavy metals, including arsenic and mercury.

An undersink RO system can provid you safe and clean drinking water all the time right at home. Waterdrop reverse osmosis systems adopt advanced filtration technology, help you save your monthly water bill.
What are the benefits of RO water?
The RO membrane can reduce a wide range of potentially harmful contaminants from tap water, such as:

1. TDS, chlorine, bad taste and odor, chloramine, scale, and turbidity.
2. Carcinogen like chromium (hexavalent), chromium (trivalent), cadmium and cadmium compounds, and ferric oxide.
3. Heavy metals like lead, mercury, barium, copper, radium 226/228, aluminum, and others.
4. Micro organic contaminants, such as cysts.
5. Inorganic pollutants, such as arsenic, inorganic arsenic compounds, and fluoride.
6. Organic pollutants like asbestos, benzene, formaldehyde, trichloromethane, chlordane, PFOA & PFOS, and others.

Cook better with Reverse Osmosis Water Filter
The water filtered by the RO system is free of chlorine and limescale, which often affects the flavor of the food. Similarly, RO water is more suitable for tea and coffee. Filtered water from the RO system is free of heavy metals and organic compounds, making it ideal for drinking. Adults and young children can drink RO filtered water to improve their health. For infants, it can also be used in combination with milk powder to prepare a milk drink.

Save Money with Reverse Osmosis Water Filter
A consumer study showed that American consumers spent $15 billion annually on bottled water. However, getting a reverse osmosis water system can guarantee a constant supply of clean and filtered water, at just pennies per gallon.

The plastic bottles used in bottled water are often not recycled; they end up in landfills where they could take hundreds of years to decompose. With an RO system, you can spend less money on accessing pure and drinkable water, while protecting the environment.
How can you choose a suitable RO system?
The most common RO Water Filter Systems filter water in 3 to 5 stages, but the top-rated reverse osmosis systems are designed to offer a 7-stage filtration. The principle is the higher the filter stage, the better the taste of the filtered water.

Tank or Tankless of Reverse Osmosis Water Filter System
The traditional Reverse Osmosis System is a Tanked RO System, which comes with a few advantages. For instance, tanked RO systems take a lot of space in your home, and when the filtered water is stored for a prolonged period, it may taste differently.

The tankless reverse osmosis systems offer a better alternative. Since they have no tanks, tankless RO systems occupy less spaces in your home. They are programmed to produce water only when it is needed, so they are economical. Plus, the filtered water from these RO systems tastes better.

Reverse Osmosis GPD
Choose the RO system with a fast water flow and low drain ratio. This ensures you do not wait for too long to fill your glass with filtered water. For best results, we recommend a RO filter system with a 800 or 1200 GPD.
