1. Types of Contaminants Removed/Reduced:

Before purchasing any refrigerator water filter, you should know about the contaminants that are currently present in your inlet water.

4. Certification:

Previously, anyone can produce a water filter and then claimed that it produced a safe & healthy drinking water. However, with independent authorities now take care of this part, you can easily find out if they are telling the truth or not.

NSF International and ANSI (the American National Standards Institute) are the two bodies that test and certify water filters according to standard, so a particular product has been certified by either or both, there is a strong possibility that you will get the quality water filters what you are paying for.

Filtration system Standards 42,53 and 401 deals with the reduction of chlorine and concerns about heavy metals like lead and mercury.

5. Usage/Filter Life:

All refrigerator water filters have varying usage in terms of the amount of water being effectively filtered or the duration of the filter itself.

Most of the filters can be replaced while others may require replacing the entire filtration system instead. Don’t worry about changing the filter a few times, or put on a filter that lasts longer instead, it will ultimately depend on your taste.

Ideally, you’ll want a filter system that lasts more than 6 months, or in some cases, a filter system that can last for years. Equipping one that lasts longer will ultimately depend on your own preference.

6. Cost/Price:

No matter what kind of product you buy, the cost is always the most important factor, and as you can see from the review above, the price of refrigerator inline filters can vary enormously.

Usually, more expensive models offer better taste water or the whole product, but you can still find good water filters that are part of the cost.

Be in good condition Some will incur additional costs such as filter replacement when the time comes, so this must be taken into account.

The warranty provides this protection if you receive a defective item or fail to function properly after a period of time. Get a water filter with a suitable warranty period that can be replaced or repaired in case of any kind of problem.

Why Inline Refrigerator Water Filter is Important?

Let’s consider one real-life scenario to understand the importance of inline filters for refrigerators. 

Assume that you don’t install any inline filter & you directly get a drinking water supply from your refrigerator’s recipient section.

In this case, the recipient section of your refrigerator becomes the house of various types of bacteria, viruses & parasites. They will start to multiply & grow very fast. When you drink this water you unknowingly intake these types of biological contamination to your body.

Bacteria and viruses are not only constraints for you. If you’re getting a municipal water supply then the amount of biological contamination is considerably low. Most of the municipal water supply treatment plants disinfect biological contamination from water using the chlorination process.

Chlorine is a super effective & very popular disinfectant chemical. It can destroy almost all types of bacteria, viruses & parasites from water. But it has a downside. It is not considered healthy for the human body.

As per the research and recent studies, the chances of cancer are 93% higher for the people who are drinking chlorinated water than those who don’t drink chlorinated water.

Another shocking fact is that the average American consumes 300-600 times more chlorine than its safer range for the human body. Consumption of chlorine is not the only problem. 

Chlorine can affect your body in another way also. Chlorine is easily mix up with organic compounds present in water and produces dangerous compounds called trihalomethanes.

Trihalomethanes restrict the production of free radicals in the human body and ultimately responsible for cell damage. Some research studies also found that trihalomethanes are highly carcinogenic. Even if you intake a small amount of it will very harmful for your body.

A refrigerator water filter is very effective in removing contaminants like Chloramine, pesticides, bacteria, viruses & herbicides. It makes your water healthier & also improves the of your drinking water.

Hope, Now you understand the importance of an inline water filter for refrigerator & why should you invest in it.

How Do Refrigerator Water Filters Work?

This inline filter is installed at the backside of the refrigerator. It contains different types of filter mediums that will remove contaminants from water. In this section, I will explain a little more details on how each stage of the filter works.

Large Water Filter:

This is the first stage of the filter and responsible to remove all types of floating contaminants like sediment, debris, rust & other types of suspended material present in water.

Normally, the filter of this stage is made of fiber or it can be made of porous material like sand. The material of this filter varies as per the model of inline filters. Some large water filters are super effective & also capable to remove some types of bacteria.

Small Water Filter:

As discussed, In the first stage contaminants like sediment, rust & debris are removed. The function of the second stage filter is to remove bacteria & organic compounds from the water. Organic compounds make the taste & smell of drinking water very bad.

Activated Carbon Filter:

The activated carbon filter is the third & the most important medium in the filter cartridge. Activated carbon has a huge surface area and a lot of porosities so that it can easily hold pollutants.

As the water passes through the activated carbon filter, most of the remaining elements flowing through the water, including chlorine, volatile organic compounds, certain pesticides, and herbicides, will be trapped by the surface of the filter.
