Buy 2 and rotate. It fits in your pants pocket, and it works! This does the trick though. Small enough to throw in your purse.

The smoke eraser v3, holds in 100% of all smoke blown into it. Both the older version and this new v4 version are and are just so much better than any smoke buddy in any size. The only downside is that you cant chose your design.

This filter works great for a *. I use it indoors with a pipe that has a lid so you can cover the burning material and * it out between puffs. Only close family knows that i am succesfully medicating my epilepsy this way.

No sign of needing to replace anytime soon. Leave them in the window seal in the sun to help dry them out.

The broken one has twice as much glue covering most of the hepa filter. The smoke buddy is one piece so it only has one place to come out. The problem is i get smoke leakage from around the edge of mouthpiece part.

Bought two to rotate usage, can't get the * things to open. Not worth saving a few bucks buy a more solid designed sploofy and not this glassjaw fragile thing.

The way it's shaped actual makes it able to blow strongly through it. I smoke out of my 3 chamber 2 foot * as soon as i wake up, i have a hefty tolerance that has to be met asap, i am no novice consumer.
