RIDE MORE.
CLEAN LESS.
Pyramid-profile foam holds twice the dirt of a standard filter — so your weekend goes to riding, not washing filters.
The secret: pyramid-profile foam
Twice the surface area. Same size filter.
FunnelWeb’s pyramid profile-cut foam doubles the external surface area of the filter without changing its size. Same airbox, same fit — twice the room for dirt to land before airflow suffers.
2022 Georgia National Enduro
Proof, straight out of the airbox.
FunnelWeb on the left, competitor on the right. Both filters were clean at the start. Both riders started on the same row. Same race, same dirt — but the FunnelWeb spreads it over twice the surface area. That's how much more dirt it can take before your bike feels it.
Trusted where it’s dustiest
Pros run it. Weekends prove it.
“I’ve been with FWF for many years now and I used to dread changing and washing filters. Now I know I can go away for a few days riding and not have to worry about taking spare filters — at dusty races and long enduros I don’t need to change filters halfway through the day like I have had to in the past.”
Jonny WalkerProfessional Hard Enduro Racer“FunnelWeb gives me security — knowing that the bike will perform in tough conditions such as dust and mud.”
Albin ElowsonProfessional Enduro Racer“With the dusty racing we have here in Australia I like the fact that FunnelWeb’s design gives you longer ride time in those conditions. The pyramid design has helped keep my engines clean and gave me an overall AORC win this season in one of the driest races we’ve had.”
