That’s why many people are attracted to these inline water filters these days.

Incomparable affordability:

Except for the other water filtration systems or water filters brands available in the market, inline water filters are way far cheaper than them. But that doesn’t mean they compromise on quality. As you can have an inline water filter in some dollars and it will still be offering you the same healthy water as any other expensive or branded water filter offers.

So, for those looking for an affordable and best solution for their refrigerator, ice maker, washing machine, and other water filtration needs, an inline water filter is gonna be the best choice to consider so far.

Easy and in no time installation:

It doesn’t matter if you have any skills or you have not made any water filter replacement before. Because installing an inline water filter at your specific place or inside a particular electrical appliance is very easy.

Some of the inline water filters offer you two-way installation and an installation guide so that you have no hassles in making this replacement. Therefore, it is another benefit offered by these inline water filters.

Money-saving versatility:

Unlike the other water filters, inline water filters require low maintenance. They can stand and keep cleaning water for almost more than 5 years. Therefore, they need low maintenance. And the same way, they cause you less money to spend.

Moreover, some inline water filters work for just 6 months, however, offer high-quality water cleaning. Plus, some let you not buy an entire filtration system for the next time. Just an easy replacement after 6 months that will cause you only some dollars.

Quality and out of sight installation:

Inline water filters offer the best quality in cleaning water because they clean water at a relatively faster pressure. Removing the impurities to the depth, what you will be drinking will be a much worthier drink.

With this, like other water filters, they do not appear at the front sight or can be seen easily. Because due to their small sizes and unique fitting areas, they are always installed somewhere in the backside of a refrigerator or ice maker. Or beneath the kitchen sink in water supply lines. So, they do not bother attention and keep doing their duty silently.

Disadvantages of inline water filters:

Now, you’ve read all the advantages of inline water filters. So let’s have a look at some important things that will make you a little disappointed in these. But not much, just a little.

Installation is not for everyone:

Even though installation of an inline water filter is very easy, I would say that installation is not for everyone. Because you must have some plumbing knowledge and also you should be capable of reading and following instructions easily to install an inline water filter at a distant place. This takes much time and most of the time, you will need some tools like a wrench or connectors, etc.

Not an easy selection:

Due to the availability of a wide range of inline water filters, it is not an easy thing to choose the best one for yourself. So, if you get a low-quality inline water filter, it means you have wasted your money and the water is still contaminated with impurities.

Therefore, you must make a wise selection before buying the best inline water filter for refrigerator, ice maker, or kitchen sink.

You don’t get a full solution to containment removing:

Since it is mentioned in the description of many inline water filters that they can do this and that. But let me clear you one thing. They are not THAT capable of giving a thorough cleaning to the water. I mean they are good at cleaning impurities from the water like Chlorine, Lead, and other heavy metals, etc.

But still, you might have some complaints regarding the quality. However, this is only infrequent cases and with some low-class models. Because most of them are best in cleaning water and removing impurities from it.

How Do I Install My New Inline Refrigerator Water Filter?

Calling for a plumber to install your new inline water filter isn’t an economical thing to do if you can make this replacement by yourself. So, hold tight and gather your types of equipment. Because I am going to teach you how you can install your new inline refrigerator water filter?

However, installation may vary depending on the type of filtration system you are going to buy. But the general process is the same as described below.

Essentials you will need:

Before you go for making an installation, be sure to have these types of equipment. The list includes some adapters for water supply connectors, if necessary, a knife or pair of scissors for giving a clean-cut, a bucket, work gloves if you have any, a towel for cleaning, and filter mounting equipment.

This is important to remember that many filters come with these or for some of them you will have to pay an extra cost. But must check beforehand.

Turn off the water supply:

The very next thing you need to do is to cut off your tap water supply first. Because the replacement process could get messy if you don’t do this. However, to turn it off, shut off the water valve that is underneath your kitchen sink.

In this case, turn it towards the opposite direction for closing it. Then turn on the faucets to release the water in the tap or any extra pressure.

Unplugging the Refrigerator:

Since you are going to install an inline water filter in your refrigerator, you need to unplug it from the socket and pull it away from the wall. Like the same, you did while replacing the waterline inside your refrigerator door.

This is because the water filtration system is towards the backside of your refrigerator. That is why you have to do so for an easy replacement. Moreover, the same thing is required while replacing an inline water filter inside an ice maker or washing machine at your house.

Installing the Filter Mounting Hardware:

Now take the filter mounting equipment and attach it to the wall. This will require you to use a drill or screwdriver to do the job. So, if you have installed it or attached it against the wall, you should make sure that mounting equipment is attached in the right direction to easily hold your inline water filter in the same direction it is recommended to be mounted.

This is because most of the filters are needed to be installed vertically while some others are horizontal. So, make sure before you get this process started.

Now, cut your water supply line:

Take the water supply line and cut it with the help of your knife or that pair of scissors. Make sure that you do this cut cleanly so that you can easily install your inline water filter in that spot. Now use your towel to clean the ends of that cut supply line.

Attaching the Inlet Tube:

Examine the body of your water filter. You will see that one side of the inline water filter is the inlet side and the other side is the outlet side. Take the waterline and push its inlet end into the inlet side of the water filter. Then give the tube a quick tug to check if it is connected properly.

Flushing the new Inline water filter:

Hold your inline water filter at an angle over the bucket with the inlet end of the water filter attached to the water supply line. Now, turn on your water supply and make sure that you have flushed at least 2 gallons of water from the filter into a bucket. After this, again turn off the water supply. This is because all the carbon residue will be removed from the filter and will make it clean to use.

Attaching the outlet tube:

Once you’ve cleared the water filter, it is time to push the outlet end of the water supply line into the outlet end of the water filter. Give it a quick tug to check if it is connected properly. Then mount the filter on the bracket. Congrats you’ve made a successful installation of an inline water filter behind your refrigerator.

Checking for leakages:

After completing the installation process, the last thing you need to make sure of is to check if there are any leakages. For this, switch the water supply on and then if there is any water leaking around the outlet tubes. Give a little more push to the tubes into the filtration system to prevent this.

Hence, if you have covered up everything, clean the area and push your refrigerator back towards the wall. Plug it again and turn on the tap. You will have crispy clean water in your cup to drink.

How to maintain your Inline Water Filter?

Most probably it will be depending on the quality of water coming inside the filtration system. Because if the water is much worse, you will need to replace the water filter most frequently.

However, you just need to change the filter itself and this is the only maintenance you will need inside your inline water filtration system. For this, you must know the filter user’s manual of a particular filter you’ve bought.
