10 Best Inline Water Filter

Types of Inline Water Filters

For many people across the globe, installing inline water filters is becoming more of a need rather than a want to live a healthy toxin-free life.

According to an NSF report, the most common filters used nowadays by people are refrigerator filters.

Many people prefer to use inline filters as they are more cost-effective and beneficial to the health of the people using them and their surroundings.

Mainly the inline filters used for water are identical looking on the outside; they have a basic cylindrical shape with various fittings on the sides of it that connect all the way up to your main water line.

Even though they are identical on the outside, the filters used inside are entirely different as different inline water filters use different insides to remove contaminants. Some of these include activated carbon, charcoal, and carbon block.

The most commonly used of the three is activated carbon.

The absorption process to trap contaminants is used in activated carbon inline water filters and is also highly effective in removing any odor or bad taste from the water.

Secondly, charcoal inline water filters are a part of activated carbon filters as they also use the process of absorption to remove toxins from the water.

During the process of absorption, the charcoal helps the toxins bind to the media preventing it from being flown through the water stream.

Lastly, carbon block inline water filters include compressed carbon that is usually finer than normal carbon that is used, which helps prevent flow channels to start forming in the media. Due to this, the water is purified enough to drink.

What is an Inline Water Filter?

Directly installed into your cold main water line is the new inline water filter, which helps deliver clean water throughout your house without dependence on any other house appliances.

The inline water filter has been recommended as highly reliable, and unlike usual under-sink filtration systems, does not require any tap installation system to be used.

One of the significant uses of installing an inline water filter is that it directly fits your main water line without any additional hassle. Another reason why inline water filters are highly recommended is that they last up to twelve months without having to change them and are also very cheap compared to regular sink filter models.

Although it may have multiple advantages, the downside of using inline water filters is that they can only be used in the main line that they are connected with. If you need filtered water in any other parts of the house, installing taps is necessary, increasing installation costs.

Drinking filtered water decreases the risk of being contaminated with different toxins and pollutants. Since the ratio of chlorine is less compared to other filter models, the taste of the water is cleaner.

How Does an Inline Water Filter Work?

We all want the best when it comes to home appliances, and choosing the most suitable and finest inline water filter may take up a lot of your time.

But it is also necessary to consider aspects like the different components in water filters, the capacity of the water it can hold in it, and many other things.

After getting an inline filter that caters to all your preferences, you next think about how it works.

An inline water filter is directly attached to the main water line of your house, after which it opens a path for effectively removing all different sorts of toxins or pollutants that may be contaminating the water.

 Secondly, after the water filter is installed, it goes through chemical and mechanical filtration stages as any other water filter does.

The two major stages that the water filter goes through include first purifying the water, after which it can be drunk.

After that, it goes through the chemical filtration stage, which is also considered to be the most crucial part because, in this stage, it removes all the toxic chemicals that may be a risk to our health and to the surrounding in general.

Hence, this process is mandatory to follow, after which the chances of contracting any health issues or water-related diseases decrease a fair amount.

After the chemical filtration process, the water is clean enough to drink, the taste of the water is also enhanced. It also removes contaminants that start from viruses all the way up to different bacterias.

Installing an Inline Water Filter?

Different purity checks are made before the water is supplied to the home in which the inline water filter is installed.

Water that is used is usually supplied through different channels like the river, etc.

This water is not safe for drinking, due to which the water is first tested and then allowed to be consumed by the public, even after which sometimes the water stays contaminated, which is why an inline water filter is used, since it is the most effective way to remove toxins from the water.

Inline water filters can be installed in your house for better and safe drinking water.

Different steps are involved while installing an inline water filter, which includes finding the perfect location where it can be installed, mainly on the pipe underneath your sink.

Secondly, the most important aspect that needs to be considered is that you need to turn off the cold supply of water from your home after finding the perfect location.

Then, start to remove the pipes under the sink, which are usually up to 3 inches long. After removing the pipes an opening needs to be cut between the tap and water supply valve.

Once an opening is created, the inline water filter needs to be placed in that opening.

The word ‘In’ is written on top of the filters, which need to be connected to the water connection lines, after which you have to connect it to the main pipe.

Lastly, multiple openings need to be drilled on the wall where the filter needs to be fixed.

After that, the filter can easily be placed into a stable position which you can further strengthen with the help of different screws.

After the filter is installed, you have to check for leaks by running the water, and it is preferred that you purchase a filter with a certified flow rate.

How to Pick an Inline Water Filter?

Many different variables are supposed to be taken into consideration before choosing a suitable inline water filter for a person.

Several factors are to be kept in mind while picking out a water filter which includes the following:

Different types of Filters:

Firstly the essential part of any inline water filter is the type of filter you choose.

Based on your specific use of the filter, you should pick your inline water filter; for example, if you’re looking for cleaner ice coming out from the fridge, you’ll need a different filter compared to if you need one to get clean drinking water from the sink.

An RV camper may need a different filter for his water supply since his water filter needs are different compared to a person who might be getting one for the sake of just purifying existing water in their household.

Various water supplies:

Secondly, you need to map out your water supply and try to understand it since everyone has a different water supply running in their homes.

The supply of water in your house may be dependant on one thing, and that is the location.

Water supply varies from place to place, the people living in urban areas have a different water supply which may have other chemicals and toxins in it compared to people living in rural areas, due to which both areas require different inline water filters to remove the toxins in their specific water supply.

In city environments, people are more exposed to water with high sulfur and minor other toxins.

While people living in rural areas may test positive for having more metal and corrosive elements in their water, due to which they need to find a filter that deals with such types of water.

The only accurate way of knowing what type of water supply you have is through getting a water test done, after which you can make a conclusion of what type of inline water filter you need to get.

Water usage and filter life:

One of the most common questions that run through a person’s mind while buying an inline water filter is how many gallons of water can be passed through the filter before it needs to be changed or a new one has to be bought.

This is why the life of a filter matters a lot for a person wanting to buy one.

Most companies advertise their water filters by saying they last a lifetime before they have to be changed or replaced.

But, the truth is it is solely based on how much water is consumed by a household and how hard the pressure of the water is that is run through them.

An example to justify the statement above is: if you are a family of three people, the filter life is expected to last longer than a house with six to eight people living in it.

Since the usage of water varies, which is why before purchasing a water filter, evaluate the number of people living in your house, the pressure of the water in your home, and how much it will be used.

An important tip that should be considered while buying a water filter is purchasing a water testing kit since it will help determine if it is working fine or not.

Pros and Cons

Advantages of Installing an inline water filter are many from which some are:

1. The inline water filter can directly be installed onto your cold water main water line. This implies that there is no need for any other item to be used; hence the reliability of the product is superb.
