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 convectional and simple/ direct inline.
Both types use cartridge combine with other technologies to provide filtered water, but installation is different.
As the name suggests the simple under sink water filter works effectively removes all contaminant but how is being installed is not complicated. It is mounted under the sink on your kitchen sink main cold water pipe/line. When installed all the cold water that gets in your house is diverted through the filter to be filtered. It doesn’t require a separate faucet for filtered water and unfiltered water and is easy to install you doesn’t have to drill a hole for an extra faucet.
The only disadvantage with this type since it is connected to the kitchen sink main cold water pipe/line. It won’t filter hot water, a lot of water is filtered so you will have to change the filter more often and lastly if the water reaching the filter has high pressure it will overwork the filter and some water will pass through unfiltered. It is a problem if you have with high contaminants
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 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 probably you will have faucet of hot water. This type will make your filter last longer because part of water is filtered and the pressure is reduced so all water that enters the system will get filtered.
The disadvantages 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 and requires plumbing for you to install the system.
