What is an under sink water filter?

Do you know the quality of the water coming out of your sink? If you feel worried about it and you don’t want to buy bottled water which may waste money and pollute the environment, you probably need to consider an under sink water filter, which is installed under your sink and purify your tap water. Once you open your faucet, you will get filtered water purified by the under sink water filter. This type of water filtration system can remove or reduce many contaminants, such as chemicals, heavy metals, virus and bacteria, etc. If you want to know how many contaminants in your water, you can read this article to learn more. Because it is installed under your sink, it will not make a mess on your countertop or faucet.

How to choose the best one?

There are plenty of models on the market. They are similar or different. How to choose the best one is also a problem if you are the first time to buy one or you just don’t feel satisfied about the current one and want to replace it. Here, we’ve list some steps you can follow to choose the best one.

Does the space under your sink is large enough for a filter? The filter will be installed under the sink and it will be attached to the water pipes. Therefore, enough under sink space can accommodate the system. Make a measurement and ask customer service for some advances. You also can choose a compact unit if you find the space is so small. If a compact unit cannot be installed, you should give up and may choose a countertop one instead.

What types of contaminants are in your water? Before you buy a filter, you should know what types of contaminants are in your water and what contaminants you plan to remove. This is because different types have different abilities to remove different contaminants.

  • Buy a water testing kit and test, and decide what you plan to filter out of your water.
  • You also can ask the water company to provide details on your water composition. Some companies may provide these details on their websites. Mostly, they are required to disclose the water composition if you use tap water.

Purchase a filter which has abilities to remove contaminants presented in your water. Different units might be designed to remove special contaminants. Therefore, you should learn more details and you also can ask sales associates about which one is the best. You also can read details on their website and read customer reviews. Generally, out tap water may smell bad, so it is highly recommended to buy one that can remove odors well.

Activated carbon filters or Reverse Osmosis systems?

  • If you water seems not so bad, you can choose an activated carbon filter to capture odors, chemicals and pesticides. You can use a replaceable cartridge, if the current one is useless. However, this type of filter is not effective to other types of contaminants.
  • A reverse osmosis system can remove plenty of contaminants in your water, including heavy metals, chemicals, virus and bacterial, and so on. If you find the quality of your water is pretty bad, you can choose reverse osmosis. This type of system can remove larger particles that are larger than water from your water and flush them as waste. Generally, most RO units use several stages of filtration methods to remove a wide range of pollutants in our water. And some of them can add back healthy minerals, make our water tasting fresh and healthier.

Choose a filter with a faucet attachment. Many units come with a faucet attachment that can allow you to use filtered water to drink and cook, while use regular tap water to clean and wash dishes. This design can prolong the lifetime of your filter.

How much money do you plan to invest? An under sink filter may cost you between $100 to $500. If you choose a RO system, you may pay more than a carbon filter. Even Ro systems vary prices and stages of filtration.

Look for filters on online website, like Amazon. Many models are easy to install and you can do it yourself. What’s more, you get a large discount on Amazon. And there are many customer reviews left by real users, which can give some advice. If you want to see it, you can check it in your local hardware store and buy it on Amazon.

Look for filters which are easy to install. If the system you purchased is complicated to install, you may need to hire a professional to do the job, which may cost you much money. If the installation is straightforward, you completely can do it yourself. If you need to replace the filters after 6 months or 1 year use, you can do it yourself.

Consider the maintenance cost. Filters need to be changed every several months or 1 year. If the replacement filters are expensive or it is not easy to change them by you, the maintenance cost will be high. Therefore, choose one with little maintenance cost.
