Best NSF Certified Shower Filters

Welcome home to a rejuvenating power bath by our very own NSF-Certified Shower Filters. The National Sanitation Foundation is a US-based standard-gauging system for determining the products that meet the strict public health standards.

Quality models vary with various NSF ratings and certifications. NSF 177 – For shower filters that attach directly to the pipe and are certified to decrease only chlorine and no other elements; NSF 43 – Lower bad odor and bad taste; NSF 53 – provides the health effect to mention but a few.

Therefore, for the products to become NSF-Certified, they must have undergone independent testing and adequately satisfied all the requirements in the NSF chart. For easy identification, NSF-Certified products bear the NSF-Mark.

Be informed there is a difference between products that are NSF-Certified and those that Meet the NSF Standards. If you have had flaky skin or dry hair over a certain duration of time, you might want to check your water status. Raw water contains so many contaminants that have proven to be irritable without question.

Unfiltered water could contain calcium, magnesium, chlorine, lead, and arsenic-all substances that are detrimental to our bodies’ health. So could you find an all-in-one solution to hard, chlorinated water?

Welcome to our informative review. In the review below, we expound on the best pick for shower filters. Most shower filters are outdated hence preventing efficient water filtration. In lieu of that, we use unique standards to gauge each filter’s performance.

These standards are contaminant removal, improved water pressure, odor removal, and durability. We will be concise, intensive, and extensive in our coverage. So if you wish to find out more, read on.
