Ready to ditch the Brita and avoid the constant refills?

The under-sink filter is the best option when it comes to ease of use (Set it and forget it), unobtrusiveness (it’s an under sink) and value for money.

Besides, your kids will always drink faucet water – when was the last time they refilled a Brita and took a sip?

We know, it’s a new product that you’d like to get to know better so we’ve broken down the essentials when it comes to an under sink filter and how it works. Read on!


How Do They Work?

Under-sink filters can work in two different ways regarding if they are using conventional or reverse osmosis system filters.

The first working method is treating all the running water that is going through the main faucet to which the filter is attached. You get faster water flow, since the water isn’t spending much in the filter to be filtered from all the harmful contaminants.

The water filter system is directly connected to the path where the cold water makes its way to the faucet. This way the filter system is treating all the water going into the faucet. You could say that the filter system is working for the all around needs in the house or office.

The second method design is only treating a part of the water supply that’s only being used from the special faucet or plug. As a result, the water is being filtrated more efficiently, removing almost all of the contaminants.

Types of Under-Sink Water Filters


Conventional Filters

The conventional filters are allowing the filtered water to pass through and come from a separate faucet. It’s connected to cold water supply only, allowing unfiltered water to be used from the original faucet.

Its installation can be more complex than other filters, since it requires an additional faucet for the filtered water and fittings to attach the cold water line, and they require an extra hole for the filtered faucet, so if you don’t have one you are going to have to make.

The benefits of this is that the filtered water is being separated and the filters are long-lasting.


Reverse Osmosis Water Filters

Reverse Osmosis is a water purification process that removes sediment and chlorine from water. There is a pre filter before it forces water through a semipermeable membrane to remove dissolved solids.

The tank system contains a raisin that lets clean water go through and it absorbs and removes the harmful contaminants by 99%.

One of the benefits about the Reverse Osmosis systems is that it will save you some money on filter replacements and gets you the most efficient way of the under sink water system.

These RO systems are more expensive than the regular filtering system, but you are getting the highest quality of filtered water, and it proves the worth of its value.

The installation on the RO system can be a bit more complicated than on the regular one, since there are a few more removable parts, but the manufacturers are improving the installation process by developing a new model.

As a weak side at the RO process we can mention that it needs to produce waste water after the filtration. This waste water needs to drain and this is considered a waste of water.


How The Reverse Osmosis Filtration System Works

The RO system offers an extensive filtering process that’s designed to eliminate all of the harmful contaminants from the tap water.

The filtration process starts by removing the sediment from your water, which includes large, hard particles like rust and sand.

Then it continues by removing the carbon, chemicals such as chlorine can damage the filter membrane if they are not removed in this stage of the filtering process.

There is a pre-sediment and carbon block filter that removes chemical contaminants that  give to the  water that bad taste and odor.

The most efficient stage is the reverse osmosis. Its membrane filter can remove 99.9% of the harmful components and other contaminants that tap water contains.

Next is the remineralization, some RO systems will remineralize the water with minerals that are good for the body like calcium and magnesium in order to balance the pH levels of the water. This also improves the taste of the water.

At the final stage of filtration, there is a coconut shell carbon block filter or commonly referred to as polishing, its function is to remove any odors or taste that the previous filters missed.


Should You Install An Under Sink Filtering System?

Companies offer new affordable models of under sink filtering systems for a reasonably low price on the market and it will save you money on the water bill.

Now you can afford to remove hundreds of contaminants from your drinking water thanks to a little filter just under your sink.

Besides the affordable price, the manufacturers have made the installation easier through the years. Thanks to their user manuals, videos, and just the simplicity of the filtering system, you can save money just by installing it yourself.

Another great thing of the filtering systems is that they have removable parts. And even if you decide to move or just simply transfer the filtering system to another faucet, you can do that with simple tools.

We highly recommend using this efficient system in your house or office.
