Hotter, Drier and Cleaner than Pellet Fuels Institute national “Premium” standards
The Pellet Fuels Institute (PFI) set standards for all pellets, including “Premium.” Cascade pellets exceed these standards in several important ways, making them Ultra Premium:

  • Heat Output: Cascade Pellets are made from hot burning Douglas fir, which produces more heat, per pound, than other wood species.
  • 25% Drier Pellets: Cascade Pellets are 25% drier than PFI standards for Premium pellets. Drier pellets contain less water, so they burn more efficiently with more home heat.
  • 75% Cleaner Pellets: Olympus Pellets produce less than 0.25% ash, which is 75% less than the national “Premium” standards. Less ash means you only need to clean your pellet stoves a few times per month.

    Best pellets I've used. High heat output and low ash. Minimal dust. Never have had a torn or wet bag. Run 24/7. Clean every 5 days. Had trouble cleaning the window but added creosote remover to the pellets and now it vacuums off. They are middle of the road price wise but worth paying a little more.
