Make your life easier, order more than one!  Especially since you have a multi-filter option, decrease time needed to filter and increase the longevity between replacements.


This 7" Gravity Replacement Filter Element (PROONE® G2.0 7" FILTER ELEMENT)

is amazing and beats out the competition because it doesn't need to be primed.  Why would you prime your filter with contaminated water!? 

This filter helps reduce and remove more than 200 contaminants including VOC™s, lead, fluoride, heavy metals, pesticides, SVC™s, disinfectants, glyphosate, inorganic non-metallics, herbicides, pharmaceuticals, PFOA, PFOS and micro-organisms while leaving good minerals like calcium.  See the lab results for more specific contaminants reductions.

  • Replacement for our gravity systems that use the 7" filters (Nomad and Big Series)
  • Nut and Alumina Free!
  • No additional filters needed for fluoride like others require.
  • 1 YEAR limited warranty on the filter media.
  • Replace the pair approx. every 10 months.
  • Designed to work with most other brands of gravity filters!

Proud to work with these Amazing Brands

We Believe

Do Your Own Research

That's what we did, and compiled these highly effective brands backed by sound science.

Our company was founded by a husband and wife team of engineers who were looking for safer water for their newborn.

We know that nothing beats 3rd PARTY LAB RESULTS with PROVEN PERFORMANCE for water filters, water structuring devices and EMF harmonization devices.



"this is the first and best purchase I've made for it! The water tastes incredible and I know that it's nourishing the cells on our body with every sip! After the first week of drinking our newly filtered and structured water, I felt my energy levels really spring back to life. I had been feeling pretty worn out and I feel really great now. Clean. Healthy water has been the biggest change I've made that has affected that."

Delphina P.
Director, Prevention Research Center, Mother of Two

"This filter system is the best! I searched tirelessly & finally found a full house system that removes fluoride, in addition to all of the other garbage. The amazing bonus I never expected is the customer service & education that Highbrow provides. I rarely see 100% ethical, helpful & knowledgeable people passionate about their work"

England D.
Founder of England's Primal Health, Mother of Three

"I am so thankful to have found this company. Their customer service is world class as they took time to help me find the perfect solution to my needs. They are true experts in the field who are not looking to just make a sale but to match you up with the right product and they really have taken the time to research the plethora of filtration options out there and focus on those which are tested, certified, proven to deliver great value. You will get the best pricing as well."
