Reverse osmosis systems are available for different house installation. They are system installed at the point of entry known as the whole house reverse osmosis system, other are installed at the point of use known as under sink reverse osmosis system and other requires no installation and are placed on the tabletop or kitchen sink top known as countertop reverse osmosis system.
In this article, we will discuss the countertop reverse osmosis system
What is the countertop reverse osmosis system?
THE Countertop RO system does not require installation and drilling so the system is placed on the countertop, tabletop. Also, like under the sink RO system and whole house RO system that has a tank, the countertop RO system is tankless.
It has a Compact design enough to fit your countertop, office desk, night table, and granite
This is the best system for people with a small home, travelers, students, and renters who cannot make a change in their plumbing. You can use countertop RO in the rented apartment, condos, hotel rooms, RV, college dormitories, or when on go.
How does countertop reverse osmosis system work?
Most countertop reverse osmosis system utilizes a 4-stage filtration system. Some come with a pitcher/dispenser where you fill untreated water.
You place the pitcher at the right place and with a touch of the button your unfiltered water pass through the filtration and you have pure water.
Others come with diverter for kitchen faucets that help connect to the most standard faucet without the use of no tool
KFLOW is a 4-stage countertop reverse osmosis water filter system. The 4-stage include
Stage 1: Polypropylene Filter-it help remove dirt, corrosion, sediment, sand, and any other physical particles. It’s working pressure 0.1 – 0.4Mpa and temperature 4 – 40°C. Filtration precision is 5μm
Stage 2: Coconut Carbon Block Filter (CTO)-it removes any additional chlorine and organic matters. Its working pressure 0.1 – 0.4Mpa and temperature 4 – 40°C. Filtration precision is 0.5μm
Stage 3: Reverse Osmosis Membrane (R.O. Membrane). The membrane is certified by CE. It helps remove bacterial, viruses, heavy metals, harmful microorganisms, antibiotics, and any other harmful substances. Filtration precision is 0.0001μm
Stage 4: Rear Coconut Carbon Block Filter (CCF). Improve the taste of the pure water to light sweet. Its working pressure 0.1 – 0.4Mpa and temperature 4 – 40°C
Reverse osmosis filter can be used for 2 years, PPF filter can be used for 1 year, Front and rear carbon block filter can be used for 1 year
This system adopts recycling multi-filtration technology meaning the water left after filtering is not hastily classified as wastewater, but will be recycled for the next round filtration with adding water. It helps save water wastage compared with the convectional RO system.
KFLOW RO system features an electronic filter indicator that helps you remind you of the remaining life of the filter and notify you when the filter needs to be replaced.
When it comes to filter change no tool is required, its Spiraled filter system makes the filter replacement easy thing.
This water filter is certified by European Conformity and All materials of this countertop water filter are food-grade-level standards.
