Start with the machine family first: Comfort Pro backpack, Pro-Lite backpack, Solar upright, Newton canister, wide-area unit, or large-capacity wet/dry style machine. Then match the quart size or exact model and choose the correct bag style such as HEPA, open-mouth, closed-mouth, or cloth.

The main difference is bag style and filtration level. X9738 is the open-mouth paper bag path, X9736 is the closed-mouth paper bag path, and X9732 is the HEPA bag option for higher-efficiency filtration.

Choose paper when you want a straightforward standard replacement path, HEPA when finer dust capture matters more, and cloth when the specific reusable bag route fits your machine and maintenance style.

Yes. If you are not fully sure about the model family or bag path, calling before you buy is the safest route — especially for commercial buyers ordering multiple packs.
