FAQs
Please read our FAQs page to find out more.
Why does the downstem have eight slits?
More slits allow more air and water to interact with the smoke, breaking it into smaller bubbles for a cooler, smoother inhalation.
Is there a specific water level I should maintain with an 8-slit downstem?
Make sure the slits are fully submerged, but avoid overfilling. One inch above the slits is a good starting point.
Can I use a carbon filter or ash catcher with it?
Yes. Just ensure your setup’s joint sizes align, and enjoy even cleaner hits.
Is it worth the investment if I already have a regular downstem?
Many find the smoother, cooler hits worth upgrading. It’s a small accessory that can make a big difference.
Does the 8-slit downstem change how I pack my bowl?
You can pack your bowl the same way you would with a standard downstem. The design only affects how the smoke is diffused.
