How To Choose Your Faucet Water Filter?

Once you start to shop for the best water faucet filter for your budget and needs, there are also certain factors that should be considered. They are as follows: 

1. Odor Or Taste

If your tap water has an unusual taste and strange odor, then you might need a water filter which will improve both the smell and the taste of the water.

2. Water Use

The amount of water needed to be filtered should be considered. If you use only a small amount every day, then it would be better for you to use a filtering pitcher. A counter-top or the under-counter filtering unit is needed for larger amounts of filtered water. But for the majority of people, a faucet mounted water filter is a great choice.

3. Contaminants

Since we don’t actually know what is in the water, the water filter should have the ability to remove the contaminants from the water. The National Drinking Water Database could help in determining the unwanted substances in the water. After that, you can compare the filters and choose the one that excels in the said role.

4. Style Or Finish

Being an extension of the water fixture, there is a high possibility that it won’t look natural in the kitchen. There are numbers of filters that are available in chrome, white, black, or the brushed aluminum finishes.

5. Filter Replacement Cost

Most of the filters should be replaced at least every 2 to 3 months, and they are particularly rated by a number of gallons of water that they could filter. Bear in mind that replacement filters costing the same as the entire unit might not be a great choice.

6. Last But Not Least - Price

And finally, most faucet water filters could be reasonable in price, but the price isn’t always associated with the filtering performance. Simply consider a great faucet water filter based on your budget and our filter reviews, of course! 

Bear in mind the above-mentioned factors once you plan to shop for the best water faucet filter for you to have a safe tap water as well.

How To Install Your Faucet Water Filter?

Before you buy your faucet water filter from the ones we have on review here, you should also learn how to install it. Follow these steps for safe and quick installation, but check out this video from PUR filters first:

Shut off the water supply. It would be the best that you shut off the water valves located under the sink just to be sure no water will come out if the faucet is turned off.

Step 1: Remove The Faucet Aerator

The threaded aerator is located on the end of the faucet which can be removed. Simply, wrap a cloth around it to protect the faucet then loosen it using a pipe wrench and spin it off by hand.

Step 2: Clean The Seal Or Threads

Clean the residue off from the threads which are at the end of the faucet right after the aerator has already been removed.

Step 3: Check If Adapter Is Needed

Check the parts and determine if there is a need for an adapter. Now, you have to take all the parts out from the package which the filter would come in and lay them on a cloth on the counter that is next to your kitchen sink. Also, you have to take a look at the sink faucet threads and identify the needed adapter piece.

Step 4: Install the Faucet Attachment Piece

There are instructions in the manual that would help you a lot. It will also tell you which piece you actually need to thread to the water faucet.

Step 4: Attach The Rest Of The Filter

And it’s time to attach the water filter bottle along with the enclosed filter into it to the part that you just threaded on the water faucet. Attach some other needed parts.

Step 5: Test If Everything Is Working

And finally, test, in order to make sure that there are no leaks and the water flow, is good.
