Making Boating Better for Boaters

Introducing the game-changer in odour elimination for your boat’s waste holding tank: The Big Orange Original filter!

Welcome to Big Orange Filter – The Ultimate Solution to Boat Odours!

If you’re tired of that unmistakable “boat head” smell every time you step onboard, you’re in the right place. Big Orange Filter was born from one Canadian family’s mission to fix the stink that comes with holding tanks – without pouring money (and chemicals) down the drain. After some smelly trial and error, a bright orange prototype with a built-in bypass valve changed everything – and not just for them. The result? A powerful, refillable holding tank vent filter that doesn’t just mask odours – it eliminates them using the same activated carbon pellet technology found in industrial exhaust scrubbers.

At Big Orange, we’re proud to offer a smart, eco-friendly, and reliable way to enjoy your boat without the stench. Made in Canada and designed with your pump-out sanity in mind, our filters are built to last, easy to maintain, and tough enough to handle the harshest marine conditions. With the largest carbon capacity on the market and a clever automatic bypass valve, Big Orange isn’t just another filter—it’s the last one you’ll ever need. So go ahead, breathe easy. Your boat just got a whole lot fresher.

Frequently Asked Questions

Do I have to be careful about what is flushed?

No. Big Orange does not filter the waste in your tank, only the air that is vented out of the tank due to flushing, boat movement, or tank expansion. Just be sure to not overfill your tank. If you do, you will need to clean out the filter and replace the carbon and filter screens.

Will the holding tank ever collapse after I install Big Orange?

Possibly. While the bypass valve in Big Orange is highly reliable, some pump out facilities are very aggressive.

How can I prevent waste in my Big Orange filter?

When measuring for the new section of vent line needed to connect the outlet of the holding tank to the inlet of Big Orange, be sure to allow for a generous loop that rises above the tank. This should prevent any splashing of waste from working it's way to Big Orange. Make sure to keep an eye on your tank level, and do not overfill your tank.

How can I tell if waste has gotten into Big Orange?

The only way to be 100% sure on whether or not waste has entered your Big Orange filter is to simply remove the cartridge and inspect the openings for waste.

Do I need to "switch on" the bypass valve every time I pump out?

No, the bypass valve is automatic. You never need to activate the bypass valve, it is operated by the difference in pressure between the tank and the vent line. Positive pressure keeps the valve closed and negative pressure (like during pump out) opens the valve.

Where are Big Orange filters made?

Big Orange is proud to be designed and manufactured in Canada.

How long do Big Orange filters last?

With proper maintenance, the Big Orange Original filter will last for years. The filter medium (carbon) that removes the odour should last at least an entire season, depending on use and conditions.

How do I maintain my Big Orange filter?

If your tank overfills and waste gets into the filter you will need to clean out the filter and replace the carbon and filter screens. Otherwise, the Big Orange filters are low-maintenance!

Went back and had my oldest daughter test the flushing and… well… nothing… Sweet, blessed, nothing… No scent, no whiff, no indication of what has taken place in the head. Awesome.
