Uni Filter

Dust and sand are an engine’s worst enemy, especially off road. Uni Filter makes foam air filters for motocross, enduro, ATVs and UTVs, built to keep dirt out and let air in. Here you’ll find replacement filters, filter oil, cleaners and accessories to keep your filter in top shape ride after ride.

American foam filters for off-road

Uni Filter is an American brand specialising in foam air filters. The idea is simple: an oiled foam filter traps fine particles throughout its depth rather than only on the surface, and it can be washed and reused many times. That has made the brand popular with motocross and enduro riders and ATV and UTV drivers who ride in dust, mud and sand. The range covers filters for most popular off-road machines and also comes in universal versions for conversions and special projects.

Uni Filter’s key products

The core is the direct replacement filters for motocross bikes, enduro bikes, ATVs and UTVs. Many are built from two layers of foam: a coarse outer layer that takes the largest dirt and a finer inner layer that catches small particles. For maintenance there is filter oil and cleaner, so the filter can be washed and oiled correctly. Uni Filter also makes pre-filters and covers that add extra protection in very dusty conditions, as well as universal filters in various sizes. See each product for model fitment.

Frequently asked questions

Why does a foam filter need oiling?

The oil in the foam is what holds the fine dust particles. A dry foam filter lets far more dust through. Use a filter oil made for foam filters and work it evenly through the whole filter.

How often should the air filter be cleaned?

It depends on conditions. When riding in heavy dust or sand, many riders clean the filter after every ride, while it can last longer in less dusty conditions. Check the filter regularly and clean it as soon as it looks dirty.
