Why NSF and ANSI Matter: The Science of Filter Certification- Filter Efficiency and Certification

Think about something inseparable from your existence! Yes, you guessed it right- Water! It is the main component of life. It is an important factor in living a healthy lifestyle, too. Drinking water is mandatory for our existence, but have you ever wondered how it may harm you if you consume poor-quality water? Polluted drinking water is unfit to drink and can result in various health issues. It might result in chronic diseases such as cancer and related issues, reproductive and nervous system problems, and the most common being gastrointestinal illnesses. It may sound minute, but sometimes the results go deadly. 

Things to practice to get pure water

There are things that might help you to get good quality water, like: 

  • Better technical growth
  • Water filtration
  • Water quality rules
  • Procedures based on current and better scientific water research 

 It provides better drinking water standards that help to reduce water-borne diseases globally.

Don't miss this! 

Standard water quality instructions and markings such as NSF/ANSI 61 persuade consumers that trusted certification organizations have tested their products for toxin water consumption.

Why do NSF and ANSI Matter?

NSF and ANSI NSF stands for- 

  • National Sanitation Foundation, a worldwide environment and public health organization
  •  ANSI stands for the American National Standard Institute. It is wholly responsible for developing standards for manufacturing and procedures in the United States. 

Rules not to miss!

Your water treatment or distribution products must abide by NSF and ANSI 61 to manufacture, distribute, and sell water treatment in North America. NSF and ANSI secure the guidelines or requirements for water system gadgets to create better water health standards. All equipments used for water treatment should meet the right standards. It is necessary to check that harmful toxins aren't released. 

What is NSF/ANSI Standard 61?

NSF and ANSI Standard 61 allot national standards related to water treatment. NSF and ANSI set strict guidelines for managing working parts that come into contact with drinkable water or machines that support filtered water production. The tests or experiments diversify from a very basic cold water test at various pH levels to many more difficult chemical certifications.

However, there needs to be clarity about these certifications to ensure they are clear. People may end up buying the wrong products in their absence. 

How do NSF Test Tanks and Accessories?

The test is basically done with a liquid before and after contact with a given equipment. It helps to analyze whether anything has leaked out or derived from the machine. Many manufacturers test pH 5, 8, and 10 exposure water at the underlying temperature. That is perfect for drinkable water storage, but these take steps to guarantee possible leakage or discharge in chemical storage tanks. Chemical storage systems require more strict testing.

The tank test is done by sustaining them for a specific period the NSF/ANSI decides. After the period, the chemicals exposed to the tank's material are studied for the existence of chemical compounds that have leaked from the tank itself.

The Science of Filter Certification

There are different levels of certification that a chemical storage system may achieve. This contrast can confuse certification, and some manufacturers incorrectly explain the certification levels of their products.

Note that many listed products, such as NSF-61, can only adhere to drinking water and not chemical storage, and many products can apply to chemical storage and not drinking water.

By going through the NSF website, which has a full list of elements by the manufacturer, you can independently confirm that a product meets the correct standards for your application. You'll see a list of chemicals that the fixings are certified for. Next to the chemical name is a percentage that marks the concentration for which the product is certified. 

For example, if you see a storage tank with sulfuric acid ≤ 75%, the tank is certified to store up to a 75% sulfuric acid concentration.

If your tank is certified but the fittings and accessories on the tank aren't, then you need to get your chemical storage system needs to be NSF-61 certified. This is why it is important to understand the difference between tank and system certifications.

A full system certification consists of even small parts like seals and fittings, which must be tested, too. When selecting equipment, it's important to ensure all materials meet the NSF-61 standards for drinkable or filtered water or chemical storage. Even the tiniest parts of your system must be tested to avoid any health hazards. 

What can save you?

If you install a Nispira water purifier, you can keep the worry aside, as the water it provides is completely pure. You can be assured that the water reaching your glass or home is pure at its best. 

Wrapping Up

Sometimes, you may get misled while checking all the efficiency and certification of the filter, but if you are using Nispira, you can go stress-free and enjoy the pure water.
