One might ask if it really matters if a water filter is NSF-certified. Or the question can be who cares whether or not a water filtration system has the approval of a third-party organization? After the manufacturer of the filtration system says its’ filter is as good as or better than the next competitor.  

Quality versus water filter cost?

Are you looking for the cheapest water filter or the best filtration that will give you the highest drinking water quality? It’s convenient to walk into any hardware store to buy a no-name water filter brand at a very low price. These systems may not have been tested by any qualified third-party agency.

Most importantly, we cannot just take the manufacturers at their words simply they say the filters have been inspected before shipping or something like that. Although they have highly paid qualified engineers and scientists that hopefully make sure they produce a better product than their competitors. Don’t you think we should trust them if they guarantee the effectiveness of their device?

Listen to the experts

While searching for filters that have been independently tested and certified, be aware that EPA makes it clear that it does not approve or certify any water filter.  EPA’s registration is not to be taken as an approval, endorsement, or a certification of a specific water filter or purifier. If you see “EPA Approved” label on a filter, return it to the shelf and move on.

Several independent organizations like NSF International, Water Quality Associations (WQA), American National Standards Institute (ANSI), and Underwriters Laboratories (UL) inspect and certify water filters. WQA and UL generally follow the NSF/ANSI certification standards.

Although there is no guarantee a certified filter will give you 100% satisfaction, NSF Standards are great way to measure the quality of water filters on the market. So, when you are in the market to buy a water filter, it is best to listen to the real experts. Water filters such as the several models by Multi-Pure are certified according to the type of contaminants they can reduce. Their water treatment devices are certified NSF/ANSI Standards 42, 53, and 58 Arsenic V, Cysts, Lead, PCBs, MTBE, Mercury, Asbestos, Chloramine, VOCs and many more other contaminants of health concern.

If you have tested your water and you know what’s in it, you can be well informed as to the type of water filter you will need for your home.
