How does the Under-sink Filter system work?

The under sink water filter system comprises three main parts. These are; the filtering device, an input tube, and an output tube connected to a faucet. From the source of your water, the under the sink is connected to the cold-water pipe which serves as the input device.

Then sends the water to the water filter. From the water filter, water passes through another flexible plastic tube towards the faucet on top of your sink than to your container or cup ready to drink or use. Not all the water from the under-sink filter is filtered but, only that which passes through the faucet chosen by the user. For the water to pass through all those pipes and the filter to the faucet until when you receive it in your cup, it moves under high pressure.

Types of Under Sink Water Filter, and How They Work

The Conventional Under-Sink Water Filter

With the conventional under sink water filter, it comprises of two faucets: the special one and the regular one. During installation, the under sink water purification system is connected to the cold water pipe then to the filter through the pipe. It then proceeds to the special faucet to have the filtered water collected. The hot water and the other cold water that passes through the regular Faucet is unfiltered. Water that needs filtering will have to be put in the water pitcher or the countertop filter.

With the conventional under sink water filter, less pressure is needed. As less water is filtered compared with the simple water filter where all the systems water is filtered. Additionally, Conventional under sink filters tend to be a bit more expensive than simple ones. This is because you must drill a hole in your sink or counter to allow your special faucet to get through. You only need to filter the drinking water therefore the filter cartridges last longer as they filter less water.

What you will like about Conventional sink water filters

  1. Higher quality drinking water is produced.
  2. The filters last for a longer period as less water is filtered.
  3. Easy to install.

What we did not like about them

  1. More expensive at the time of installation

The Simple Under-Sink Water Filter

Under the Simple under sink water filter, all the cold water from the water source is diverted through the input tube to the filter system and then to the common Faucet. It is only the hot water of the water system which leaves without filtration unlike for the conventional where even some cold water is unfiltered.

During the installation of this under sink water filter, you do not need to drill any hole in your sink for an additional faucet which makes it affordable. With the simple under sink water filter, you need to filter all the cold water in the system be it for drinking, washing, or cooking. Hence, its filter and Faucet need regular replacement.

What you will like about the Simple under sink water filter

  1. You spend less to install the filter.
  2. All the cold water is filtered.
  3. No drilling through the sink.

What we did not like about the filter

  1. It requires regular replacement of the filters.
  2. The higher flow rate of the water makes some of the filtration tasks less practical

Should You Buy Under-sink or Countertop Water filter?

The Difference Between the Under-Sink Filters and Countertop Filters

The names of these filters display their location and connection. The under-sink water filter is placed beneath the sink such that the water connected to it gets filtered before it gets to the final Faucet. For the countertop water filter, it is placed either on the counter-top or beside the sink.

Under-sink filters tend to be wider than the countertop filters because below the sink there is enough space compared to the countertop. When it comes to filtration rate, the under-sink filters are better than the countertop filters. The countertop filters tend to interfere with the design of your kitchen so when buying one, one must consider the colour in the kitchen or drinking room to match it well.

Under-sink Water Filter Buying Guide. Tips For Choosing The Best

There are certain features that one should consider when choosing the best under-sink water filter.

  1. Flow Rate

This refers to the speed at which water moves through the filter to the final Faucet and then to the collector. It is measured in gallons per minute and as you are buying your under sink water filter, consider the flow rate you opt to have in your home. However, the flow rate of your filter is affected by other varying factors such as the particles in your water, water pressure at your home, cold water temperature among others.

  1. Capacity

While buying an under-sink filter, also look at the capacity of the filter it can hold and how much you need for your home. The capacity of the water which runs through the filter also affects the replacement of the cartridges. You will find filters that filter fewer gallons of water within a given period. And then they require you to replace them regularly. So one should put this in mind. Still, about the capacity, some filters can filter large gallons of water but when they can only remove a few.

  1. Water Pressure

The flow rate of the water depends on the water pressure which determines the time you spend on your sink waiting for just a cup of water. During purchasing that water filter check out its pressure because it helps to also boost the overall pressure of the system.

But you should keep in mind that with higher pressure, water spends less time within the filter and so some contaminants might be left behind without being filtered. It means you must be aware of the available contaminants. This is done by using a testing kit and then go for a highly effective water filter.

  1. Maintenance and installation

Easy installation and replacement of filters should be part of the important factors to consider when you go to purchase an under sink filter. More reasons to consider ease of installation is that you do not spend a lot on the process, fewer risks to damage the filter during installation. Some under sink filter systems do not require professionals to install them. So, this would be a great choice if you are looking at buying any filter. In case professional installer and maintenance personnel is required, always consider the cost.

  1. Filter longevity

In most cases, the longevity of the water filter is determined by the capacity and type of contaminants in the water you intend to filter. The user should bear in mind that replacing filters is not as free as you need to buy a new one. Hence, you should so opt for a filter that is directly proportional to the contaminants of your water, hence longer longevity. Having to change your filters is annoying and price dependant. While buying the under sink filter, consider one with a change reminder just in case of replacement. But, not all filter models do have these features.
