How to choose the best one?

First, you should know what types of contaminants in your water you want to remove or reduce. If your water is relatively clean and just contains some fluoride which causes bad taste and smell, you just need a relatively easy filter to remove it and your water quality will be improved heavily. However, if your water contains many heavy metals and other types of contaminants, you may need a relatively advanced filter to make sure all the contaminants can be effectively removed or reduced. To many of us, we don’t know how to start, so a water quality test is a good start which can help you find out what types of contaminants in your water. You also can ask your water company for a water testing service. Some test reports are also available on the internet.

If you find the water quality is pretty good, a 1or 2-statge water filter is enough, which can help you easily reduce the chlorine and sediment. And you don’t need to spend much money to get an advanced one because it is just a waste of money. However, if the water quality is pretty poor, a 1 or 2-stage filter cannot remove all the contaminants in the water. For example, heavy metals are still in the filtered water. In this situation, a more than 3-stage water filter is needed to improve your water quality.

In most situation, a reverse osmosis system is the best choice for the under sink water filter. Why? Generally, our water contains many types of contaminants, such as chloride, arsenic, copper, Iron, Mercury 2, lead, sodium etc. Such a RO system can effectively remove and reduce these contaminants. You may spend more on such a filter, but it deserves.

Before making a decision, the following tips are helpful for you.

Check customer reviews: The customer reviews can tell you more. Because you haven’t used it, the experience left by other users can help you know whether it is good for you. You many find positive reviews or negative reviews, but you should know what you really want and focus on the major reviews. Or some negative reviews mislead you, because there is no perfect product on the market.

Initial Cost: The second thing you need to consider is the initial cost. Much more expensive models may not the best ones and you may waste your money. Finding out the most cost-effective by comparing features with prices is a good idea.

Maintenance cost: Besides the initial cost, you also need to consider the maintenance cost. After normally six months of use, you need to replace the filter with new ones. Therefore, you should know how much the replacements filter is. And replacement filters must be easy to get. Therefore, choosing the popular brands is a good idea.

Easy installation: If the model you choose is difficult to install, you may need to hire a plumber which may cost you much money. Therefore, choose one with an easy installation, and you can install it yourself without extra spending on installation.

Space and compatibility: Before ordering a new one, you must know whether the under sink space is enough for your filter. And compatibility with your fixtures and appliances is also very important.
