⭐⭐⭐⭐⭐
When other Holding tank vent filters failed us in just a couple of months, we set out to design a completely new solution that not only 100% eliminated holding tank odors but would last well into a second boating season.
The kit had to come with everything needed and be very easy to install.
We also wanted the ability to easily refill this filter with our proprietary activated carbon blend saving the significant replacement cost and eliminating the plastic waste that comes with purchasing a whole new unit each season.
