- Measuring Guide
To ensure a proper fit, measure your vent pipe's outside diameter (O.D.) and use the following table. Vent Pipe Manufacturers size their pipe by the inside diameter (I.D.). Because OdorHogs fit over the outside of your vent pipe, we care what the outside diameter is. The O.D. you measure will be slightly larger than the actual filter size you order. This tells us whether you have a standard thickness of pipe and that your OdorHog will fit properly.
PVC or ABS Vent Pipes:
|Vent Pipe INSIDE DIAMETER||Vent Pipe OUTSIDE DIAMETER||SIZE TO ORDER|
|1 1/2 inches||1 7/8 inches||1 1/2 inch OdorHog|
|2 inches||2 3/8 inches||2 inch OdorHog|
|3 inches||3 1/2 inches||3 inch OdorHog|
|4 inches||4 1/2 inches||4 inch OdorHog|
|6 inches||6 7/8 inches||6 inch OdorHog|
