Listed below are a few things that you need to consider before deciding on which is the best inline water filter for your needs.

  • 1. Daily Filtration Rate

Basically, the design and function of all water filters are more or less similar. But, there are some factors that differentiate each of them. Prior to choosing the right product for your needs, you need to have a rough estimate of its daily filtration rate.

For in-line water filters, this maximum daily rate is measured using gallons per day (GPD). The filtration rate is something you must take into consideration because powerful filters offer a higher filtration rate.

  • 3. Effectiveness in Eradicating Contaminants

One of the main reasons why people install in-line water filters is to remove impurities and contaminants from the water they drink. Even in tap water, there are impurities that are naturally present, but it’s important to note that these can pose a risk to your health over time.

Biological impurities and chemical pollutants in the water you drink from the tap have the ability to cause serious issues such as hormonal issues, high cholesterol, and so on. In addition to that, there are heavy metals such as lead and arsenic that can be found in unfiltered tap water.

That’s why it’s important to choose an inline cold water filter that is capable of removing as many of these contaminants as possible.

  • 4. Quality of Water

Water filters aren’t just about purifying the water in removing contaminants, but they also about improving the overall quality of drinking water. There are a lot of other things that can be wrong with water such as bad taste, a foul odor, maintaining the pH, and keeping all the necessary minerals that are good for the body. These are all the things that high-quality in-line water filter can achieve.

There are different filters, such as reverse osmosis filters and activated carbon (AC) water filters that provide the ideal solution to help fight foul and pungent tastes and smells in the water. They filter out harmful elements which destroy the flavor and nutrients of water, helping to make it safe and healthy for consumption by you and your family.

  • 5. Installation Process

Step 1: Find the Location

One of the best places you can set up your water system is on the cold water supply pipe beneath the kitchen sink.

Step 2: Remove the Pipes

The next step is to turn off your home’s cold water supply before removing the cold water pipe underneath the kitchen sink. This may be up to 3 inches in length. Use the pipe cutter to help you remove the section between the water supply valve and the tap.

Step 3: Set up Connections

Now that a gap has been created, all you have to do is install the water filter in that section. Connect the inlet of the water filter to the water connection line. The outlet has to go to the main pipes. The two ends are clearly marked for identification with ‘in’, ‘out’, or other symbols.

Step 4: Place the Filter

Your next step is to drill holes on the compartment wall where you can place the filter and attach it to the wall. There’s a bracket that you can use for placing the filter with screws to attach it on the wall firmly.

However, for most people, finding the right way to clean your filter can be challenging. If you want to reuse your water filter and simply take the steps listed below:

Fill up a bucket with half a gallon of water. Pour 2 cups of muriatic acid into the bucket slowly. Gently mix it with a long plastic stirrer until it’s thoroughly blended. After that, you can set the bucket aside. Loosen the debris from your water filter using a high-pressure hose. Spray each side of the filter, and concentrate on those areas that have a buildup of calcium or rust.

Submerge the filter in the acid solution in place the bucket in an area that is secure and ventilated, away from children and pets. Leave the filter to soak in the solution for about five days.

Pour half a gallon of water into a separate bucket and remove the filter from the acid and place it into this bucket for about five minutes. Afterward, remove it from the water, rinse it thoroughly using a high-pressure hose and then you’ll be able to reinstall it into your water filtration system.
