Ecoflo compact biofilter — the septic system that's installed for life
Failed perc test. Small lot. Seasonal use. No matter your site, our solution works where conventional systems won't.
How it works and why it lasts
More than 100,000 property owners across North America trust the Ecoflo compact biofilter to treat their wastewater.
The reason is simple: it's an energy-free system with no mechanical parts, built around a coconut husk filter that removes pollutants naturally.
The filter lasts up to 15 years or more with proper care. When it needs to be renewed, we install a new one in the same tank. No digging, no disruption. The system itself stays in the ground for life.
What is the Ecoflo compact biofilter?
Most septic systems use a conventional drain field to treat wastewater. That works on open land with good soil — but not everywhere.
The Ecoflo compact biofilter is designed for situations that don't fit the mold.
Small lots with tight setbacks. Clay, rock, or slow-draining soil. High water tables. Sites near a stream or wetland. Properties used seasonally, where a system sits idle for months at a time.
Because the bulk of treatment happens inside the biofilter rather than a drain field, it opens up options that conventional systems can't offer:
- an installation footprint up to 50% smaller than a conventional system
- direct discharge to a stream or ditch — no drain field required — when paired with our UV disinfection unit
- nitrogen reduction for areas with strict wastewater quality requirements
NSF certified and manufactured at our factory in Williamsport, Pennsylvania, the Ecoflo compact biofilter has been trusted in the USA since 1995.
Your solution when conventional isn't an option
If you've been told your land can't support a conventional septic system, you're not out of options.
The Ecoflo compact biofilter can reduce the size of the drain field you need — and in some cases, it can eliminate it entirely.
That makes the system ideal for sites with:
- failed or marginal percolation tests
- high water tables or seasonally saturated soil
- clay, rock, or slow-draining soil
- shallow bedrock
- limited space or irregular shapes
- strict wastewater discharge regulations

Designed for properties that aren't used every day
Unlike other septic systems, the Ecoflo compact biofilter is perfectly adapted for intermittent use at cabins, secondary homes, short-term rentals, and remote properties.
Many advanced systems rely on a pump or aerator to treat wastewater. At a seasonal property, that creates two problems:
- If you switch the system off when you leave for weeks or months, it needs time to recover before it can treat wastewater when you return.
- If you lose power during a storm, your system goes offline — and you may not be there to notice.
These aren't worries with the Ecoflo compact biofilter. It uses no electricity for treatment, so there's nothing to switch on or off and no vulnerability to power outages.
Its coco filter naturally retains moisture, keeping the microorganisms inside it active during long periods of non-use. When you arrive at your property, your system is ready.
What does an Ecoflo compact biofilter project cost?
The honest answer is that it depends. The state where you live, your site conditions, and the size of system you need all affect the final number.
For a detailed breakdown by state, our cost guide covers everything you need to know.
What the numbers don't show is the long-term value of the Ecoflo compact biofilter.
Other septic systems eventually need to be replaced. It's a disruption that can run into the tens of thousands of dollars, often with no warning or alternative.
The Ecoflo compact biofilter replaces that uncertainty with something predictable: a no-dig filter renewal — at a fraction of the price of a new system — that restores your system to day-one performance.
