FAQ
Product
How often do I need to change the filter?
12 months or 1,000 gallons, based on water condition.
How to install the countertop RO water filter system
The K19-S countertop reverse osmosis water filter system is installation free and requires no
drilling nor messy holes.
How to fill the RO water filter system with water?
This water filter system has a large capacity and can be easily filled with water by simple
lifting, which is very convenient to operate.
Where should I put this water filter system?
This water filter system adopts a plug and play design. It can be used in any place as you wish,
like a living room, a kitchen, an RV, a bedroom, etc.
Do I need to replace the UV lamp regularly?
Most reverse osmosis systems are designed to reduce most contaminants in water through
micropores of RO membranes. However, bacteria which are not intercepted by the RO membranes will
still breed in inside pipelines. Our UV sterilizer can perfectly solve the problem, because up
to 99.9% of bacteria can be reduced through UV sterilization. Therefore, the best water filter
system should integrate UV sterilization with the RO system to provide the most purified
drinking water. This is why we design the K19-S countertop reverse osmosis water filter system.
Is this reverse osmosis water filter system unit suitable for well water?
We do not recommend using well water as source for our RO systems. The reasons are as
follows:
1. Large particles.
Compared to municipal tap water, the well water is rich in large particles, which will clog the filters easily, and shorten their life significantly. Please note that the filters will still need to be replaced more frequently, even if you have added a pre-filtration system.
2. Composition
The well water has a very complicated composition, 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.
