How To Choose The Best Under Sink Water Filter

There are a few factors that you can’t afford to miss when buying an under sink water filter because if you do, then you will end up buying a bad product. Here are those important factors that you need to keep in mind:

Water Pressure

With more and more people complaining about the water pressure being reduced after installing a water filter, it becomes important for you to check that this problem doesn’t occur with the under sink water filter that you plan on buying. The water pressure needs to be normal (a bit slow is justified because it is being filtered). If it is too fast, then that means the filtration process was not done efficiently.

Filtering Capacity

Some filters are more efficient in removing contaminants than others. You will also find many models that incorporate excellent filter system, but they are not capable of removing a specific type of contaminant. To ensure that you are buying a good product, you must check the contaminant type and ratio using a home water quality testing kit. This test will make you familiar with the type of contaminant(s) present in the water coming into your house and in what amount.-

Installation & Filter Change

When buying an under sink water filter, you must pay attention to the installation process. It is recommended to choose an under sink water filter that is easy to install or else, you will have to call up a professional, which increases the overall cost of the unit. Besides installation, you must check as to how easy or difficult the process of changing filters is. If it is easy, then consider the product, otherwise move onto the next one.

Cartridge Longevity

This parameter varies from company to company, as you may come across models in which filters need to be replaced every six months or so, whereas, you will also find models in which the filters are changed after 2, 3 or 5 years. The role of cartridges is the same in all filters, but the ones that are lasting longer are made with high-quality components, so I would prefer to opt for those cartridges.

However, the cartridge may not last for as long as it has been advertised, the reason being the quality of water in your area, which may be different than the water used at the time of checking the quality of a particular cartridge. Therefore, you need to be a bit flexible with the time frame provided by the company as it can up or down depending upon the quality of water running from your kitchen faucet.

Wrapping Up
