Some of the factors to consider include:
Source of water
It is important to consider your source of water as some waters have higher hardness levels than others. For example, well water is more acidic as compared to municipal water. Some filters don’t have the capacity of dealing with very acidic water. There are also some which will not alter your water PH if that is what you are looking for.
It is important to both know the water pressure of your home and the water pressure of your filter. There has to be a balance or else you will have issues with leaks. If the water pressure of the water filter is too low, you might have to invest in a booster pump.
The flow rate of the water filter you are interested in is very important. No one would want to find themselves in a situation of inconvenience because the flow rate of the filter is too low.
The water capacity of the water filter is very important as it should be able to sustain your home. The water capacity is also a great indicator of how long the water filter will last.
Warranty/ after-sales service
It is also important to consider the warranty of the filter that you are buying and the kind of after-sales service available. That will give you confidence that the material used is of good quality and that you can always get support whenever you need it.
Some materials are not BPI free and hence may release harmful compounds and lead in the drinking water. Always check to make sure that the filter is made from food-grade material.
AS much as the certifications are not the overall base of the judgment of a good filter, they can give you confidence that the filter meets standards. A good filter should be NSF/ANSI certified.
