How does reverse osmosis system work?
The water supply in your home gets in under pressure, irrespective of
where you live. Reverse osmosis relies on this same pressure to push water through a semipermeable
Water passes through the semipermeable membrane under pressure. This leads to the
separation of the impurities from the water molecules. The impurities are on one side of the membrane,
and the water molecules on the other, with the clean water going to your tap without any impurity
whatsoever. There are several filtration stages in the RO water filtration process - up to seven
sometimes, and these are responsible for the high purity of water.

How long does a reverse osmosis filter last?
The integrated filter in this system needs to be replaced once every year.
When to replace the filters of this reverse osmosis system?
You should replace it only once a year, depending on the quality of your
Can I connect a water softener with this reverse osmosis system?
a. Please note that the water softener is NOT designed to provide
drinkable water. Its main function is to soften the water for washing clothes, taking a bath, flushing
b. If a salt-based water softener is installed BEFORE the RO unit:
water could be salty since our unit can only remove 90% salt added by the softener.
-The RO filter's
lifetime could be shortened due to the unusual amount of sodium in the source water, which is NOT
covered by the warranty.
-We have already put a clear warning on the product page regarding this
c. If your water softener is NOT salt-based, then our RO unit should work properly with

enjoying your road trip.
Is this reverse osmosis water filtration system suitable for well water?
We do not recommend using well water as source for our RO systems.
reasons are as follows:
1. Large particles.
Compared to municipal tap water, the well water is
rich of large particles, which will clog the filters easily, and shorten their lifetime
significantly.Please note that the filters will still need to be replaced more frequently, even if you
have added a pre-filtration system.
The well water has very complicated compostion,
and some of them (apart from the large particles) can cause the filter or internal valve to be clogged
and prevent the RO system from normal performance.
3. Water pressure
The well water may not
provide the feed water pressure that the RO system requires (14.5 psi min.). Furthermore, the water
pressure will be even lower after passing through pre-filtration systems.
Do I need to have an electrical outlet under my sink for this work?
Yes, the system requires electricity to work. So, an electrical outlet is
Can I connect the remineralization filter with this reverse osmosis water 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
” and add the filter.
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
