Summarize the following:
Moisture from your breath collects inside the Smoke Buddy every time you use it. Set the Smoke Buddy on a table or in another open area to help it dry out and last longer. 3 months is the approximate amount of time each unit lasts. This equates to about 150 uses for the Jr. size and 300 uses for the regular size. Depending on how frequently you use yours, it may need to be replaced sooner. You will be able to feel when this happens. The filter will be completely clogged, so smoky air will accumulate inside the Smoke Buddy. You won't smell clean air coming out the unit's smaller end.
Leave the caps off after using the Smoke Buddy. Use the Smoke Buddy for up to 3 months. Replace the Smoke Buddy when it's hard to blow through.
