What to Look for When Buying NSF Certified Water Filter
Buying an NSF-certified water filtration system is not as complicated as it sounds. One only needs to exercise due diligence in studying different products, looking out for specific attributes. It would be best for potential buyers to consider the following factors.
- Correct NSF Certification
The National Sanitation Foundation (NSF) has standards for specific water quality parameters and product attributes. It would be best to familiarize oneself with the different NSF water filter listing standards.
For example, an NSF-42 standard only addresses the water’s aesthetic qualities, while an NSF-53 qualification underscores a water filter’s ability to remove health-hazardous compounds. Meanwhile, an NSF-55 certification is only for water filters with ultraviolet systems.
A reverse osmosis system should have an NSF-58 certification, while a water filter for emerging contaminants should have an NSF-401 rating.
Prospective buyers can use the NSF search tool to check if the water filter they want to buy has an appropriate NSF certification.
For example, to answer the question is Cuckoo water filter NSF certified, one may have to type in the NSF search bar the ‘Cuckoo” brand. It will show that this brand has an NSF-42 qualification for its CPF-80XX series of water filters.
- Water Filter Type for One’s Needs
One can choose from a multitude of water filtration units. There are point-of-use systems that supply filtered water to a single fixture. Examples of these water filter types include faucet filters, refrigerator filters, inline water filters, water filter pitchers, and under-sink water filters.
Point-of-entry water filtration systems are perfect for whole-house applications. They deliver filtered water to every tap and water appliance in the home.
One can also choose water filtration systems based on their filter mechanism. For example, one can pick a sediment filter if the only concern is large particles or sediment in the water. A carbon filter is suitable for removing the nasty smell and taste of chlorine and other compounds.
Households worrying about dissolved solids can choose a reverse osmosis system or a carbon filter with ultra or nanofiltration. These units can also filter out microorganisms, including cysts, bacteria, parasites, and some viruses.
Filters with UV light are ideal for killing microorganisms in the water. A re-mineralizing membrane can balance the mineral-removing capabilities of a reverse osmosis system, returning beneficial elements into the water.
- Water Filtration Characteristics
It is always best to check the water filter’s performance characteristics, including filter capacity and flow rate. Filters with larger capacities last long. It can translate to better savings for the family because they will not replace the filter very often.
Flow rate is also crucial because it underscores how much water one can enjoy within a given unit of time.
Is NSF Certified Important
Yes, NSF certification is essential in ensuring the truthfulness or authenticity of a company’s claims regarding its water filtration performance.
It is the public’s safeguard against scrupulous companies, ensuring their water filtration performance pronouncements have the validation of a trustworthy, unbiased third-party quality standards organization.
An NSF-certified or NSF-listed water filter tells consumers that the manufacturer observed high-quality systems, processes, and methods in designing and constructing their products. All materials undergo rigorous testing, validation, and certification to ensure their appropriateness and safety for human water consumption.
What is the Difference between NSF 42 and 53
According to the National Sanitation Foundation, the NSF 42 standard reflects a filter’s ability to reduce aesthetic impurities, including chlorine odors and tastes. The contaminants
On the other hand, an NSF 53 standard pertains to a filter’s capacity to lower the number of contaminants with EPA-defined health effects. It can include filtration and adsorption processes, such as what occurs in carbon filter media.
A related NSF standard to NSF 53 is NSF P473. NSF P473 certified water filters can reduce the levels of perfluorooctanoic acid (PFOA) and perfluorooctanesulphonate (PFOs), which the EPA classifies as major environmental and human health hazards.
Are Brita Filters NSF Certified
Not all Brita filters have NSF certification. Some may have the NSF logo, but a closer inspection of the filter may reveal the qualification is only for select water contaminants.
It is also worth noting that some filters undergo testing, validation, and certification by the Water Quality Association, using NSF/ANSI standards.
The best NSF certified water filter gives consumers the confidence and security they need from their water filters. It removes whatever contaminants or impurities the manufacturer claims because a trustworthy, unbiased organization already qualified the product.
The certification also guarantees high-quality materials and manufacturing processes, giving families and individuals additional reasons to feel good about using the water filter. They can increase their water consumption, leading to better health and enhanced wellness.
