 Last updated  - January 12th, 2022

The NSF is accredited by the American National Standards Institute (ANSI). They have set the standard for water filters across the globe. Furthermore, with new refrigeration filtration technology, ensuring your replacement filters are NSF 53 certified refrigerator water filters is essential. 

The NSF uses a special, consensus-based process to develop standards. It means that regulators, consumers, industry, and academia are involved in developing those standards, to ensure maximum human protection. There are more than enough reasons to trust products with NSF/ANSI standards.

Things To Know Before Buying

Any medium can be used to filter water. However, it doesn’t mean that it perfectly cleans the water, or does anything at all. Moreover, if the filter is not certified, it might even be dangerous. It might cause chemicals such as arsenic to reach and contaminate the water.

On the other hand, if the filter is certified, you will have no problems when it comes to purifying the water. Some certifications can even mean that the filter is lead-free and completely safe to use. Let’s talk a bit more about the NSF/ANSI certification.


When it comes to international standards and certifications, it might get confusing. Unless you are directly connected to the industry, you don’t need to bother with too many details.

Basically, NSF and WQA are very similar organizations. They both do the necessary testing to satisfy already-maintained rules and standards. Both NSF and WQA perform testing on various products and satisfy the regulations provided by ANSI and SCC (Standards Council of Canada).

Products NSF Certification Process

Having an NSF (or WQA) certification is very important for manufacturers. That’s why they voluntarily submit their products for testing. There are various regulations that the product has to meet during the testing. In the end, if the product has met all but a single regulation, it can’t get a certificate. That’s why NSF certification is very important when it comes to product quality and safety.

Types of Certifications

The last criterion to consider before you move forward with your quest for the best filter for your home is the certifications. It is important that filters can perform the way they advertise. Home drinking water treatments are becoming popular. It is difficult to differentiate between manufacturers and advertisements.

Certification is as vital as the results of your water test. How do you know a product will work as they promise? How do you know it won’t do more harm than good? The answer lies with NSF and ANSI certifications.

All products coming with an NSF International mark meet the strictest standards when it comes to public protection. The same goes for ANSI and products certified by the European Union’s agencies. Before installing any type of filter in your home, read everything about how the manufacturer tested and certified it.

Here are some National Science Foundation (NSF) standards you can consider:

  • NSF Standard 42 refers to the filter’s aesthetic effects: Filters meeting this standard reduce chlorine. This improves the taste and odor of your drinking water. The rule mostly addresses carbon filtration.
  • NSF Standard 53 refers to the filters’ effects: A NSF 53 water filter has to meet the minimum requirements for the certification of POU/POE filtration systems. An NSF 53 filter removes a long list of contaminants from your water. This can include Cryptosporidium, Giardia, lead, volatile organic chemicals (VOCs), MTBE, etc.
  • NSF Standard 58 refers only to reverse osmosis filters. The standard certifies that the RO filter reduces toxic pollutants, chemicals, bacteria, etc. Certified RO systems decrease the levels of the following contaminants in your water. The list includes TDS, cysts, chromium (trivalent and hexavalent), arsenic, nitrate/nitrite, cadmium, lead, barium, turbidity, fluoride, copper, VOCs, asbestos, radium 226/228, perchlorate, selenium, etc.
  • NSF Standard 401 refers to incidental contaminants or emerging compounds. The standard (and thus, the filter) can cover up to 15 contaminants found in water as of late. The standard lists human/veterinarian pharmaceutical drugs (prescription and over-the-counter medication), flame-retardants, pesticides and herbicides, BPA, precursors to commercial detergents, and more. The NSF Standard 401 also applies to RO water filters.

Most filters you will find on the market meet the NSF standards 42 and 53, while others can reach more.

Difference Between Standards

It’s not enough to say that the product is certified. The number that comes after the label is even more important. Therefore, we have 4 different NSF/ANSI standards.

1. NSF 42

We can say that 42 is the lowest standard of all four. meaning they usually remove chlorine and offer a better tasting and odorless water. A good example of an NSF42-certified product is a water pitcher filter.

2. NSF 53

This certification can be considered as a higher-level certification than 42. Although it includes all 42 standards, it also takes care of your well-being. Products certified with this standard reduce specific contaminants.

The NSF 53 certified refrigerator water filter uses carbon filtration. However, the quality of carbon filters determines their ability to remove contaminants, and at which percent. That’s why filters certified with this standard can significantly vary in their ability to reduce contaminants. Most of these filters are installed below the sink. Also, some products might even have multiple filters.

3. NSF 401

This is a relatively new standard. It was developed after certain pharmaceuticals were wound in tap water. These filters also test the water for various prescription drugs and reduce various herbicides, pesticides, and detergents.

The most common product with this standard is a carbon filter. It can be used under the sink, or inline for a refrigerator.

4. NSF 58

Products with this certificate include reverse-osmosis systems. However, since RO systems can’t remove contaminants that carbon filters can, most of these products already include carbon filters.

Using reverse-osmosis, systems are able to remove nitrate, nitrite, cadmium, copper lead, and various heavy metals. They usually come with a pre-filter or post-filter that uses carbon. Like carbon filters, RO filters also vary when it comes to the ability to reduce contaminants.

Why Choose a NSF 53 Certified Refrigerator Water Filter

As mentioned, with this certificate, you won’t have to worry about whether or not you are drinking clean water. With that kind of filter, all the contaminants with negative effects will be removed. These contaminants include copper, lead, mercury, barium, cadmium, cyst, asbestos, and similar.

The NSF 53 certified refrigerator water filter is especially important if you live in an area where water is contaminated. Also, frequent rain and weather changes might affect water. Since ANSI standards involve regulators, consumers, industry, and academia, your drinking water will be perfectly safe.

Choosing the Right Filter

Certification Necessity

The first question that you might ask yourself is whether this certificate is necessary or not. Let’s break it down a little bit.

If a filter doesn’t have a certificate, it doesn’t mean that it’s bad. It can do an excellent job even without a certificate. However, among two filters without a certificate, you can’t be sure which one is better. The thing is, the other filter might even be harmful.

If your filter is certified, you don’t have to worry. You don’t even have to completely understand what the NSF certificate is. You can simply use the filter, knowing that it will provide maximum results when it comes to both aesthetics and safety.

Choosing According to Your Needs

When choosing a filter, you should consider what exactly you need. Then, you need to check which certificate a filter has, and decide whether to buy it or not. For example, if you want only to improve the water taste, an NSF 42 certification would be enough.

If you want a filter that improves water’s effects, look for 53 certifications. If you live in an area where water might be contaminated with herbicides, pesticides, and chemicals, look for 402 certifications. In the end, if a reverse-osmosis filter is what you need, make sure that it satisfies NSF 58 standards.


There is always a lot to think about when protecting your family’s health. This is why making sure your NSF 53 certified refrigerator water filter is up tp date. Just make sure that the one you choose fits your fridge.

If you are not sure, you can always contact your fridge support center or search the web. The ones on out list fit various models and we are confident one will fit your needs, and fridge.
