Next Generation Reverse Osmosis Filter

In a traditional RO filter, the purified water is stored in a tank for later use. However, a tankless reverse osmosis water filter eliminates the need for a storage tank. Instead, it uses a direct flow-through design, where water is filtered on-demand, providing a continuous supply of purified water without any waiting time.

High flow undersink reverse osmosis filters provide a continuous supply of filtered water on demand. This ensures that you have clean drinking water available whenever you need it, without the need to wait for a tank to refill.

Frequently Asked Questions about Reverse Osmosis Water Filters

Undersink Reverse Osmosis Filter

What is reverse osmosis and how does it work in water filters?

Reverse osmosis is a highly effective water purification process utilised by advanced filtration systems. By employing a semipermeable membrane, reverse osmosis filters exert pressure on water, allowing pure water molecules to pass through while blocking impurities, contaminants, and particles. This process ensures the removal of harmful substances such as bacteria, viruses, heavy metals, chlorine, fluoride, pesticides, nitrates, sulfates, and various other contaminants commonly found in tap water.

Are reverse osmosis filters compatible with different water sources?

Yes, reverse osmosis water filter is designed to function efficiently with diverse water sources, including municipal water supplies, well water, tank watre and tap water. In general, most standard reverse osmosis systems are designed to handle TDS levels up to 600 ppm.
However, it is crucial to assess the specific impurities present in your water and choose a reverse osmosis system that can adequately address those contaminants

What impurities can reverse osmosis water filters effectively eliminate?

Reverse Osmosis system effectively eliminates around 96% of all dissolved impurities, TDS and salt.
Reverse osmosis water filters excel at removing a wide range of impurities, including but not limited to:
Viruses and Bacteria: polio, rotovirus, norovirus, E. coli, Legionella.
Heavy metals: lead, ferrous iron, arsenic, cadmium, chromium, selenium, mercury
Chemicals: Chlorine, bromine, flouride, iodine, nitrates, sulfates, pharmaceuticals, organic acids, proteins.
Contaminants: Sediment, rust, dirt, bad taste, and odours.
Others:  (VOCs), PCBs, BPA, and many other contaminants.

Does reverse osmosis water filters deplete essential minerals from water?

While reverse osmosis filters are highly efficient at eliminating contaminants, they also might remove beneficial minerals such as calcium and magnesium from water. However, advanced reverse osmosis systems often incorporate additional stages, such as remineralisation, to reintroduce essential minerals into the purified water, ensuring a more balanced and healthier drinking water experience.

Do reverse osmosis systems waste water?

Yes, reverse osmosis systems produce both purified water and waste water. The ratio varies depending on the system, but it’s typically around 3:1 or 4:1 (waste water to purified water). However we supply modern RO systems which designed to be more water-efficient and reduce waste, it’s up to 1:3 (waste water to purified water)

Can I install a reverse osmosis water filter system myself?

Yes, many reverse osmosis systems are designed for DIY installation. Our RO systems are DIY, easy to install and come with detailed installation instructions, reverse osmosis filtre installation videos and all the necessary components. However, if you’re not comfortable with plumbing or have specific concerns, it’s advisable to hire a professional plumber or handyman to ensure proper installation.

What RO water filter faucet options are available?

1. Standard Faucets: These are basic faucets that come with a separate handle for filtered RO water, Our filtered water taps are available in many finishes and colours, See our options
2. Three Way Mixer Taps: These faucets have two handles—one for hot and cold water, and another dedicated handle for filtered water. They eliminate the need for a separate filtered water faucet, See our options

Do a reverse osmosis system need a power source to oporate?

Most advanced reverse osmosis systems require a power source to operate. The power is typically used to drive the water through the membrane, which is a crucial part of the reverse osmosis process. Additionally, some systems may have additional components such as pumps, TDS meter, lifespan indicators or electric valves that also require power.

However, there are some non-electric reverse osmosis systems available that do not rely on electricity, they run on the water pressure (more than 40 psi).

The Reverse Osmosis Filter

Reverse osmosis (RO) is a water purification process that uses a semi-permeable membrane to remove dissolved solids and impurities. Reverse osmosis membrane has around 0.1 Nano (0.0001 micron) pore size which contributes to a very high removal capability of Fluoride, Lead, heavy metals, ions, bacteria, viruses, calcium, chloride, copper, iron, magnesium, nitrate, nitrite, colloids and silt, and many more, thereby producing ultra pure great tasting water.

A reverse osmosis process has several filters that work together to remove impurities from your drinking water. Generally, the RO system involves four stages: The first filter is a sediment filter that removes particles such as dirt, sand, and rust. The second filter is a carbon filter that removes chlorine, chemicals, and other contaminants. The third filter is a reverse osmosis membrane that removes dissolved solids such as fluoride and lead. The fourth filter is a carbon polishing post filter that removes any remaining impurities in the water such as chlorine, taste, and odor.

A reverse osmosis water filter is excellent because:

  • It is very effective in removing contaminants from water
  • It is easy to install and maintain
  • It is relatively affordable
  • Designed to fit into the existing water supply

Compared to other water filter systems, reverse osmosis filters have a higher quality of filtration. They are also more effective in removing contaminants such as fluoride and lead. If you are looking for a water filter system that can provide you with clean, safe, and pure drinking water, then a reverse osmosis water filter is the best option for you. Purified water comes out the tap at the normal water pressure you would expect.

Water purification is the process of removing undesirable chemicals, materials, and biological contaminants from water. The goal is to produce water fit for specific purposes. Most water is purified for human consumption (drinking water), but water purification may also be designed for a variety of other purposes, including medical, pharmacological, chemical, and industrial applications.

Note that a reverse osmosis water system uses extra water. As part of the filtration process, contaminants are removed and these are washed out through the waste water exit. This waste water can be recycled for alternate use, or washed down the drain. Waste water is normally generated whenever purified water is used.

Optional post stage

Mineral Filter, The reverse osmosis process will remove all contaminants and minerals and a remineraliser filter will add minerals back to the water which will raise the pH level of the water to be alkaline.

RO filter is recommended for people who want the highest quality of water possible or for those who have water with a high TDS (total dissolved solids) level.

If you are looking for a reverse osmosis water filter system that can provide you with the highest quality of water, then a system with a mineral post filter is the best option for you.
