CF FILTER Reduces rust, sediment, large particles, chlorine, taste and odor.

MRO FILTER Reduces most contaminants, such as antibiotics, organic matter, heavy metals, nitrite, bacteria, and limescale. Improves the taste of water and provides purified water that is as fresh as spring water.



The reverse osmosis membrane has a pore size of 0.0001 μm, which is one-millionth of a strand of hair. Bacteria and viruses are 5,000 times larger than its pore size.

Only water molecules and some beneficial mineral ions can pass through the RO membrane. Heavy metals and other impurities are discharged from the waste water tubing.



🔵 Blue = Filters are healthy and functioning well.
🟣 Purple = Prepare to replace the water filter within about 15 days.
🔴 Red = Replace the water filter.



The tankless reverse osmosis system ensures the safety of your family’s drinking water. This compact RO system also saves over 70% more under-sink storage space as compared to traditional reverse osmosis water filter systems. The tankless design avoids recontamination, such as bacterial growth.

      Excellent Way to Have RO Water at Home.

      This is a much more simplified system than the traditional RO system. With it being on demand you won't have the added maintenance associated with RO water storage tanks. This makes for a better system pressure, faster dispensing of filtered water and fresher water as well. I really like that it includes a remineralization cartridge. You can add one to any RO system, but that It comes with one is great. I think the key to having this CF & MRO system is to also purchase a stocking supply of the filters. You will want to change them at a certain interval and keep them changed. As there are only 2 filters on the system they will only last so long as they are combination filters composed of many layers of different filtration media. WaterDrop recommends 1 yr on the CF and 2 yrs on the MRO filters. I think this is a max interval and you might find that if your water supply has a lot of sediment or rust or other contaminants that you will need to change the CF filter more often. You can tell when there is a reduced flow of filtered water that it is time to change a cartridge. Alternatively you could purchase and install a 5 micron sediment filter prior to this filter and then plan on changing the sediment filter every 6 months or so. That should extend these filter intervals to their max 1yr/2yr rating. I think these on-demand RO units are the way of the future. No more adding air to the storage tank to boost the flow of filtered water. No more post storage tank activated carbon filters to change. The only downside to this filter is that it is not recommended to feed a refrigerator or ice maker. Well, I guess you could then get a storage tank after all and just have it in-line to the refrigerator and only for it. Then you will still be getting fresh RO water at the dispenser faucet. 5 stars.

      Perhaps the best under sink RO system

      I just finished installing this myself, following the provided instructions. It was super easy

      Updated and easy RO design

      This is a brilliant design. It eliminates the holding tank as in other RO systems, and need for sanitizing them.

      Comparable to the more expensive name brand
