What is the Ecoflo compact biofilter?
The Ecoflo compact biofilter is an alternative septic system that provides advanced treatment using a 100% natural, renewable, and compostable coco filter.

How does the Ecoflo compact biofilter work?
The Ecoflo compact biofilter treats wastewater in just a few steps:
- Wastewater from your septic tank enters the Ecoflo compact biofilter.
- Inside the compact biofilter, wastewater is evenly distributed across a filter made of coconut husk fragments.
- Wastewater percolates through the coco filter, where naturally-occurring microorganisms remove contaminants.
- Effluent discharges to your septic drain field or additional treatment components (if required).
Why is the Ecoflo compact biofilter installed for life?
To understand why the Ecoflo compact biofilter is installed for life, you need to know three things about how other septic systems work:
- All septic systems produce sludge — a thick mix of solids that bacteria can’t fully break down. Over time, it builds up.
- Sludge eventually reaches your drain field, where it clogs pipes and surrounding soil, causing your system to fail.
- Most systems are buried and inaccessible, so the only solution is to dig them up and replace them.
The Ecoflo compact biofilter is different. Here's how:
- Sludge stops here
The system’s coco filter acts as a physical barrier, capturing pollutants and sludge before they reach your drain field.
- No system failure
Each coco filter lasts 13 to 15 years (with proper care, it's often longer). When the time comes, we simply renew it. You never need to worry about drain field clogs or system failures.
- Easy access
It's easy for technicians to open your system’s lid, remove the old coco filter, and install a new one in the same tank. No excavation. No full-system replacements. No damage to your landscaping.
- Guaranteed performance
Filter renewals restore your system to day-one performance. After the service, we automatically renew our original warranty covering clogging, excess sludge, and treatment quality.
