I love these things! So tired of ash hitting my throat - ugh. No anymore
Absolutely love it! Doesn't work on all my pieces but works with enough of them that I'll be buying a few more next time I place an order.
This screen fits perfectly in my Grav Caldera bowl. It works like a charm and prevents little 'scoobie snacks' from making their way into your mouth (or water. Benefits: Way less ash in your mouth or bowl (practically none in my experience) Doesn't really seem to block the air flow of a draw so when you use it you totally forget it's there When you cash your bowl and invert it to empty, you no longer have to worry about your screen falling too. The page says 'permanent screen' but you could totally use something like tweezers to pop it out of your piece for cleaning/reuse. Cons: None. Just the remorse that you didn't get one of these a lot sooner.
The best idea yet! Soak them in alcohol, use a pipe cleaner to help clean them. Just rinse and reuse. Can be adjusted depending upon the size of bowl as the hole for filter may differ in size.
