Protect your property and the planet with the Ecoflo biofilter, the septic system with the lowest carbon footprint.

New to the world of septic systems? See what a septic system is and how it works.

What is the Ecoflo septic system?

The Ecoflo biofilter is the most sustainable septic system available and the best way to protect your property and the environment for the future.

This energy-free treatment system gently removes wastewater pollutants with a filter made of coconut husk fragments or a combination of coco and peat moss. Both materials are natural and compostable, and coco is 100% renewable.



The Ecoflo biofilter is most often a solution for:

  • primary residences
  • seasonal cottages
  • residential developments
  • apartment buildings
  • campgrounds and parks
  • office buildings
  • schools
  • temporary work camps

Start-up visit

After your Ecoflo biofilter is installed, we visit you on site to teach you how it works, answer your questions, and make sure your septic system is working perfectly.

Please note that this service may not be available in all regions.

Compare septic system warranties

The Ecoflo biofilter warranty is clear and complete. There is no fine print or hidden tricks.

Compare that to the competition. Other manufacturers warranty only certain parts of their system. Few cover the cost of labor. And none of them guarantee what matters most: the treatment performance that protects your property.

Wastewater first flows into a septic tank. Solids settle on the bottom of the tank and liquids flow into the Ecoflo biofilter for treatment.


Inside the Ecoflo biofilter, a non-mechanical tipping bucket scatters wastewater across perforated distribution plates. Wastewater drips through these plates and falls across a filter made of coconut husk fragments or a combination of coco and peat moss.


This filter is the heart of the Ecoflo septic system. It creates a physical barrier that captures and removes wastewater pollutants.


After percolating through the all-natural filter, wastewater flows downstream for additional treatment or for safe discharge into the environment.
