There are mainly three types of under sink water filters such as Simple Water filter, Reverse Osmosis, Conventional Water filter. As we move further you will get to know which filter will be suitable for your house. We have explained in detail what types of different filters are available in the market. Our motive is to get you the best under sink water filter.

Simple Under Sink Filter

Under Sink Water Filters Simple

Simple Under-Sink Filter connects directly to your already existing cold water supply, and the water will flow out of your existing tap. It doesn’t use a separate faucet to deliver the filtered water. It rather have two different faucets, you have one faucet that will deliver you the filtered water. You can consider this type as an affordable option. Simple Under-Sink Filters may force you to frequently change the filter due to its connection to one single faucet.

Reverse Osmosis Systems

Reverse Osmosis systems use the membrane to filter the water. These systems are very effective under sink water filtration because it is a multistaged filtering system. Mostly all the Reverse Osmosis systems have dedicated faucet it is beneficial to you it will save money on replacing the cartridges. One of the downsides of this system is it produces wastewater and this process needs to drain the water it has a dedicated outlet port for wastewater. Reverse Osmosis systems are a little bit higher side on the price but it will give the best filtration among the other filter in the market.

Conventional Under Sink Filter

Under Sink Water Filters Conventional

Conventional Under-Sink Water Filter will connect to your cold water supply line as it were the case in the simple system but it will give you dedicated faucet on your countertop. It will still allow you to use you the other faucets for other water uses. It is very beneficial because it will give your filter a longer life. In conventional style, the system makes sure you do have an extra hole in your countertop for the dedicated faucet.

Benefits of Under Sink Water Filter

2. A technology named mineral booster which is present in almost every water filter. It helps you to get the minerals that are necessary for your body into your water with ease.

3. The under-sink RO water purifier improves your immune system. The major reason behind weakening your immune systems are the various bacteria in your water. Hence these water filters.

4. We are not saying it is too cheap but we do believe that if you invest in a good under sink water filter then it will have less maintenance and that will definitely give you a sense of savings.
