Frequently Asked Questions

Are Tri-X Filters Ceramic or Paper/Fabric

The unique Tri-X filters are made of a high performance three dimensional ceramic material. Being three dimensional means the filtration material has length, width, and depth. Traditional filters rely upon the paper/fabric media to catch particulates in a single pass. The Tri-X filter not only filters by using the elements surface area (length x width), it also uses the medias depth (third dimension). Filtering by depth rather than just surface filtration makes the Tri-X filter much more efficient.

Are these filters marked on top with P/N 0969601

Yes, these filters have raised letters and numbers on the top saying P/N 0969601.

Many people believe that P/N prefix means that 0969601 is the part number for this filter. However, the correct part number is 73178.

Is the Tri-X 73178 filter the same as the 73250 filter?

Yes, the 73250 part number is used by the manufacturer for identifying a case quantity vs 73178 which identifies the individual filter.
