What Is an Inline Water Filter?

As the name suggests, inline water filters are the type of filters that are installed directly into a water line. Therefore, water is filtered as it passes through the pipeline. Inline water filters are long, thin, cylindrical shape filter cartridges that remove dirt and other harmful substance from your water. Besides this, it limits the limestone formation which protects your precious equipment.

Reasons for Using Inline Water Filter:

Inline water filter is a highly trusted water filter type that people uses in their homes and offices because of the following reason:

  • They are durable and efficient
  • Versatility is endless with an inline water filter. Just install it in one kitchen line and use it with more than one appliance such as a water cooler, ice maker, refrigerator, etc.
  • They are space savers and doesn’t require a big area for installation
  • Inline water filters are an economical and pocket-friendly option that is just like long–term investment.

Some Cons of Inline Water Filter:

  • Installation is a bit tricky:

In this era where inflation rate is increasing day by day. You look for ways to cut –off the labor cost. Unluckily, inline water needs an experienced plumber for its installation. You can’t do it on your own. Though installation is simple but it needs expert knowledge.

  • Confined to be used with limited appliances:

Inline water filters are not like whole house water filter that supplies pure and clean water from every faucet of home. You can only install an inline water filter to be used with the fridge, ice maker, kitchen sink. It doesn’t cater to the need of your entire house appliances.

  • Not a thorough contaminant removal:

Inline water filters are useful for removing the majority of the contaminants like chlorine. But if your water has a high level of heavy metals, then inline water fails to filter them properly.

How Do They Work?

Inline water filters work immediately as soon as you installed them. Their working is really very simple. With the help of water pressure in your plumbings, water is pushed through the inline filter which has different layers of filters.

The first stage or first filter layer removes toxins, chemicals, and other impurities from water by using a filter medium. The second stage revolves around the removal of chemicals. Depending on the type of filter medium it removes different chemicals and toxic substances from water.

At this stage, the taste and smell of water are improved while different viruses, bacteria, and VOCs are effectively removed. The result is clean and pure water that you can use for making ice, cooking, and drinking.

Types of Inline Water Filters:

There are different types of inline water filters depending upon the filter medium that they are using to filter water from harmful contaminants. Below, we have mentioned some of the most common types of a filter medium that are used in inline water filters:

  • Charcoal: 

Charcoal is a popular filter medium that is used in numerous water filtration systems. An inline water filter that has carbon as a filter medium removes contaminants via the adsorption process. In this process charcoal binds the contaminants to the media. Therefore, no contaminants will pass through the system with water.

  • Granular filter:

For trapping a wide range of different contaminants, a granular filter is the best choice. Actually, it’s a blend of multiple filter mediums. Using filter medium of different pore size, it effectively removes numerous chemical and substance from your water. 

  • Activated carbon: 

It is one of the most commonly used filter mediums. In inline water activated carbon traps the contaminants molecule and binds it with the filter medium. Therefore it doesn’t let the contaminants enter into the water. Activated carbon is very effective for removing chlorine and unpleasant odor from your water.

How Should You Buy an Inline Water Filter – Buyers Guide

Inline water filter is a life-saving option when you want clean and purified water from your faucet. You may found many different brands of inline water filters which do nothing but leave your mind a big hotchpotch. So if you are planning to buy an inline water filter on your own, we will help you. Here we will share some points that will help you in buying an inline water filter

  • Filtration Rate:

 The filtration rate is actually the number of gallons your filter can treat per day. With this, you can estimate the working capacity of your inline filter. Filters with exceptionally high filtration rates are quite expensive but they are of immense use for big families. Therefore, based on the need of your family, choose an inline filter with a suitable filtration rate.

  • Installation Process:

Be it an inline water filter or whole house water filtration system, installation is a tricky process. if you have some plumbing experience then installing an inline water filter underneath your kitchen sink would be a child’s play for you. But for naïve people who want to cut off the extra labor cost, there are certain models of inline water filters that are comparatively easier to install.

  • Capacity:

The majority of the inline filters that are available in the market, usually have a minimum capacity of 3000 gallons and a maximum capacity of 20000 gallons. The capacity of the filter indicates the gallon of water after which you need to change the filter.

A filter with 3000-gallon capacity can easily work up to 6 months whereas a filter with 20,000 gallons would be more than enough for 5 years. When comparing low and high-capacity inline water filters with their prices, you will be amazed to know that there isn’t any significant difference between the two. In fact, the high-capacity inline water filters are cost-saving. As you buy it once and need to change it after 5 years.

  • Certifications:

Certification is one of the important factors that you need to look into when buying an inline water filter. I think if your inline water filter is safety certified, this will give you peace of mind that you are using one of the best water filters in town.

Usually, inline water filters have NSF standard 42 certifications which assure no chlorine taste and odor in water. Very few inline water filters have NSF 53 certifications which claim that the filter will remove lead and heavy metal from water. So depending upon your quality of water chooses an appropriately certified inline water filter.

  • Lifetime of inline Water Filter:

Every product existing in this world has some expected lifetime. The same goes with an inline water filter, it has got some expected time frame after which you will have to change the filter. 

It all depends upon the working of the inline water filter or how much water you put through it. And it varies from family to family.

For a small family of 4 members, water usage will be low, so the life of the inline water filter would be extended as you will not be using it so often. Similarly, for a bigger family where consumption is higher, the expected life of an inline water filter would below.

The best tip to determine when the filter needs a change is to keep a water testing kit with you. After every month, test the water and you will get to know either your filter is doing a great job or not.

FAQS

what is the best filter for my inline water?

There are many different brands of inline water filter that claims to be the best. But we personally like Watt inline water filter and ECOlife inline water filter as one of the best filters in the market. 

How often do I need to change my filter?

Well, it totally depends upon the brand and filter cartridge you are choosing. Every brand of inline water filter has some specific capacity or filter life, after which you flow rate of water becomes slow. This is the right time when you should change the filter.

What happens if we keep using an inline water filter after its specific lifetime?

If you keep using an inline filter after its stated lifetime, the contaminants would start accumulating on the filter and it filters water at a slower rate. Therefore, you won’t get clean and purified water like before. In short, there would be no use of a water filter. So, it’s recommended to change your filter cartridge before ending its lifespan.
