Key Features
[Revolutionary filter structure]: Waterdrop D4 RO reverse osmosis water filtration system adopt innovative technology and design to integrate different filtration materials into a 6-in-1 composite filter, after full research on the properties of various materials. The filter uses the least space to achieve an optimized filtration effect, reducing TDS, chlorine, heavy metals, and more.
[Great upgrade with small size]: The elegant machine is only 12.44-inch in height. The tankless design makes its size even smaller, which can save more space under the sink.

Yes, this reverse osmosis water filtration system can work with your RV.
It has an integrated design that makes it possible to install it even in a tiny under-sink space, such as
RVs. You can combine this filter system with your RV for a regular and reliable supply of clean
water. Now you can stop using the dirty and unsafe water from campgrounds. This filter system ensures
you get clean and pure water for drinking directly from your taps and shower. You are also immune to the
common health issues associated with contaminated water, which may prevent you from enjoying your road trip.
Can I connect this machine with the mineralization filter?
Yes, this reverse osmosis water filter works perfectly with a
remineralization filter. All you have to do is buy a suitable remineralization filter and connect it to the
system. Simply search for "Waterdrop Remineralization Filter" and add the filter.
How often should I replace the filter? Can I replace it by myself?
The D4 RO system only requires replacement once a year. You don't have
to estimate when to replace your filters. It's very easy for you to complete the replacement by opening the
front panel and removing the old filter.
Does the system need the electricity to run?
Yes, the Waterdrop RO system need electricity.
Can the reverse osmosis system be connected to the refrigerator so the
ice is filtered as well?
1. Generally speaking, yes, The RO system can be connected to your
refrigerator. After completing the registration online, you could choose the accessory kit, which will
help you connect the RO to your refrigerator/ice maker. Since different refrigerator/ice maker has a
various requirement of water pressure, it's not possible for our RO system to provide them all.
Connection under mismatched circumstances may result in many problems, including but not limited: slow
ice making, frequent start-stop issues, etc. Therefore, it's NOT recommended to connect the RO system to
your refrigerator/ice maker. 2. To determine if the RO's outlet pressure is enough to be connected, you
may need to acquire the refrigerator's pressure requirement first, which can be found in its user
manual. For your reference: RO's outlet pressure: ca. 35 psi
What does Pure to Drain Rate mean?
The reverse osmosis water filter relies on a semi-permeable membrane to
filter out impurities from drinking water. When the tap water is compressed through the RO membrane, it
produced pure water and waste water. The ratio of pure water to waste water is called wastewater ratio. 1:1
wastewater ratio means 1 gallon water is wasted per 1 gallon purified, and 2:1 wastewater ratio means 1
gallon water is wasted per 2 gallon purified. The higher the wastewater ratio is, the less waster water
produced during the filtration process. During the use of RO water filter, the actual ratio might be lower
than the labeled, depending on many factors such as water quality, pH, pressure and temperature.
