- This system produces up to 190 liters per day of purified water and is delivered complete:
- A 3 US gallon pressurized storage tank containing 6.5 liters of reverse osmosis filtered water.
- An installation manual.
- Chrome tap.
- All hoses, pre-filters, post-filters, and fittings required for easy installation.
- The membrane can last between 1 and 2 years depending on the hardness of the water. Filters must be replaced every six months.
The osmosis systems reversed e wastewater to make water, and it must be done at high pressure because the water is forced through microscopic holes that capture contaminants.
This is normal and the same with all reverse osmosis systems, because it is the way the membrane rejects impure water, which goes to the drain, to produce pure water.
The system operates optimally at 5.5 – 6 bar (80-90 PSI), and to achieve the indicated flow rate, we recommend operating the system at or around this pressure.
This allows the system to reduce the wastewater / pure water ratio and work faster to produce pure water.
Since many people do not have this network pressure, reverse osmosis systems or booster pumps can be purchased from us and added to the system, which will increase the outlet pressure (a minimum of 2 bars (29 PSI ) is required to operate the booster pump).
Please make sure that the water pressure in your network is equal to or higher than this pressure before buying it.

Top 10 Best Under Sink Water Filter: Buyer Guide
Now, we will tell you the most important factors that are required in the buying of the best kind of under sink water filtration system. Some of these important factors are described following:
Flow rate means how much a filter system produces filtered water in one minute. This flow rate is found out by Gallons Per Minute. It is the most significant factor that reveals the speed of the filtered water. Most of the water filters have a flow rate of 0.8 to 2 GPM.
The life of the filter is the second most important factor. The installation and replacement of the filter may be easy or not, depending on the nature of the filter systems. The long-lasting filters are more suitable to use because if the life of the filter is low, then it costs you much and also take your time to replace the filter again and again.
Healthy minerals retain in the water:
The best water filter system is that which easily removes all the harmful chemicals and contaminants but keep the healthy minerals remain in the water. The healthy minerals are necessary for the freshest water.
The micron rating is as important as the filter cartridge. Micron rating means that how much the size of the particles are filtered out by the water filtration system. Most of the best quality water filter system has a rating of 0.5 Microns. The smaller number of microns is more effective for the water filtration system.
Easy installation and Filter change:
The process of installation and the replacement of the filter must be easier. The DIY installation is the best for the water filter. The water filter comes with full essential parts that are required in its installation. If the process of installation is easier, then the filter system is best to purchase.
The changing of the filter should be easier. Every filter has its life span and after that life, the filter must be changed. Some of the life of the filer is six months and some filters have a life between 2 and 5 years. After the time of the filter’s life, the filter should be changed in order to maintain the long-running of the water filtration system. We hope that all the above factors are helpful for you.
