It has a flow rate of 2gpm
How to install CuZn UC-200 Under Counter Water Filter
What you should look when buying under sink water filter
There are a few features you should consider when buying under sink water filter. These include:
Types of under sink water filter
There are two different types of under sink water filter
simple/ direct inline.
Both types use cartridge combined with other technologies to provide filtered water, but installation is different.
Simple/ direct inline under sink water filter As the name suggests the simple under sink water filter works effectively to remove all contaminants but how it is being installed is not complicated/ it is simple.
It is mounted directly into the main water line under the sink in your kitchen.
All the cold water that gets in your kitchen sink’s main water line is diverted through the filter to be filtered.
The simple system is installed in an already existing faucet.
Advantages of direct inline
It doesn’t require a separate faucet for filtered water and unfiltered water.
This type is easy to install you do not drill a hole for an extra faucet.
Disadvantages of the direct line
It is connected to the kitchen sink main cold water pipe/line so a lot of water is filtered so you will have to change the filter more often therefore maintenance can be expensive.
If the water reaching the filter has high pressure it will overwork the filter and some water will pass through unfiltered.
The conventional is the opposite of simple its installation is complicated.
You need to divert kitchen sink main cold water pipe/line to the filter using a connection.
When the water is filtered, it is sent to the separate faucet installed in the sink.
You will have two taps one for cold water that is filtered and the other one for cold unfiltered water.
This type will make your filter last longer because not all water that gets to your kitchen sink main cold water pipe/line is filtered.
The convectional system the pressure is reduced so all water that enters the system will get filtered.
The of this type you require a sink that has two faucet holes if not drill an extra hole in the sink
It reduces the water flow rate
Requires plumbing for you to install the system.
The conventional system, the water pressure is low, therefore, you can wait for a few minutes before you get a full glass of filtered water.
Which contaminants it removes
Under sink water filter has a combination of the filter with different technologies which each removes the specific contaminant. Not all are designed the same so make sure you purchase the system that filters contaminants present in your water.
You can use a water test kit to know contaminants present in water.
Easy to install and maintain
Most of these systems are easy to install they come with the DIY installation process that you can do alone at home without hiring a professional.
Since the system use cartridges that require to be replaced after a period the replacement should be smooth and straightforward.
Under sink water filter removes contaminants using different techniques such as reverse osmosis, reduce hard minerals and some brands go up to six stages which include alkaline remineralization.
Check the system that has the most filtration technology because will help save a lot of money and space.
Also, the more the filtration stages the better because the system will provide quality filtered water.
Under sink water filter use cartridges to filter contaminants in the water.
The cartridge doesn’t last forever so requires to be replaced.
You should know how long the filter will last for it to be replaced.
Some brands need their filter to be replaced after filtering specific gallons or a few months, but this can be different due to some factors such as quality of water and amount of water filtered.
You should follow the manufactures instruction on when to change the filter.
Some companies have a filter indicator to inform when it needs to be replaced.
Water flow/ pressure
As we said earlier if your water pressure is high and you are using simple system some contaminants will escape and pass through unfiltered. In the conventional system, the water pressure might be low, therefore, you can wait for a few minutes before you get a full glass of filtered water. Know the flow rate of your system or water supply pressure before buying the filter.
Independent certification is the only way to guarantee your water system removes contaminants effectively and is made with quality material.
There are independent bodies such as NSF and WQA that test and approve most water systems.
Which contaminants do under sink water filter remove
The under sink water filter use cartridge combined with other technologies to remove contaminants such as: Bad Odor and taste Since the system has a carbon activated filter which helps remove chlorine odor and taste. Also, activated carbon filter removes organic, inorganic chlorine, heavy metals, herbicides, pesticides, algae, and molds. Removes heavy metal The carbon filter combination removes heavy metals such as lead, mercury, chromium VI, and cadmium. Particulate removal The system has a polypropylene sediment filter that removes particles, dust, silt, and rust. Reduce hard minerals (calcium and magnesium) that form scale on home appliances
