Copy of How it Works (w/ Tips, Secrets & Best Practices)
The key to reaching 1000 to 1400 exhales with your Smoke Eraser is keeping your HEPA filter dry. Through our unique patent pending pre-filter system, we've managed to separate and collect 90% of the condensed water vapor passing with each breath of exhaled smoke. The specially treated hydrophobic breath barrier blocks these tiny water droplets without adding resistance to airflow resulting in the preservation of the HEPA filter. With HEPA filter staying drier longer, this significantly slows filter restriction. The fact is, it's water reaching and soaking the HEPA that's at the heart of why sploofs almost never exceed the commonly stated claim of just 300 exhales. This inconvenience our customers will never worry about. The accumulating moisture bounces off the hydrophobic barrier and then absorbs into the black collection sponge held under the lid. We call this the Breath Collector Sponge (see image below). Eventually this becomes saturated as it's continually withholding moisture that would otherwise soak the HEPA filter prematurely killing the sploof.
You'll want to periodically dry the sponge. The frequency with which you do determines the lifespan of the unit. I recommend drying the pre-filter after each session and then leaving the lid off until next use. See 1st video below for instructions. Watch the 2nd video to learn 2 more simple techniques that will extend the already long lifespan of your Smoke Eraser.
1. Pop off and dry underside of lid and breath barrier.2. Remove sponge, smash inside a napkin to dry.
3. Leave lid off until next use to to dry breath humidity.
Watch video above to learn how to clean your Breath Collector Sponge of resin and also learn a 2nd trick to increase rate of airflow. This allows you to push smoke through the HEPA filter more easily by opening up pleat spaces lessening restriction. Often done near the end of the sploofs life, but can be done anytime you wish to lessen back pressure. 
*Conclusions regarding the pre-filter upgrade. Proactively drying sponge piece at regular intervals, properly storing unit when not in use, and just being diligent about maintaining an open and dry environment between sessions, reaching the 1000 to 1200 exhale mark should be relatively easy for most. This will depend largely on the factors above and seriousness of smoker. Also interesting, results so far of cycling 2 units at once, rotating daily, show both units having reached the 1400 exhale mark but with neither having reached any kind of ceiling. Furthermore, each unit after adequate drying time (8+ hours), is blowing through totally restriction free. That's with almost the same free flow today as when new. Unexpected and impressive, this would be something to surely consider. And although definitely interesting to note, we still must contend with the fact our activated carbon cannot be made limitless and therefore at some point will begin to lose its effectiveness to remove 100% of the odor. But until then, we of course plan to continue testing the rotating Smoke Erasers to find out if an end even exists. As of this point, we can only say that cycling 2, with proper attention given to keeping the resting unit open at both ends and being attentive regarding how often and when to dry Breath Collector sponge, we have exceeded 1400 exhales fairly easily. Furthermore, this has proven to be the most cost efficient way to use the product.
More tips...
• So overnight, between sessions, or just anytime not using your Smoke Eraser, in the spirit of always working toward keeping the filter element as dry as possible, be sure to leave the lid off as this allows it to be open from both ends.
• In the (rare) event of such extreme use your Smoke Eraser prematurely becomes difficult to blow through, you my friend, are on another level. Not gonna say you don't exist or that it's impossible to do, its just not a common occurrence and well, you would just need to be accommodated for too. So if you have been regularly purging the breath collector sponge and you're pinching your breath barrier each time between the lid and bottle as shown in video, and you can still actually clog the filter, on any given day by yourself; then you're going to want to give it a rest. Break it down and set it on its side til next day, and it will very likely be wide open again (fyi: a hair dryer works as well). Now buy a 2nd and begin rotating them 1 day on 1 day off. It's just smart and it will ensure you reach a good 1200+ exhales (on each) and likely have you exceeding this quite noticeably as an increase in drying time between sessions is directly proportional to increase in lifespan. Cycling 2 is going to always be more cost efficient as it results in more exhales.
*FYI: Not only true for heavy smokers. Any user would experience the increase in exhales when rotating 2 Smoke Erasers.
With longevity comes sustainability. And with such an exceptionally long life span, the Smoke Eraser remains the most cost effective and environmentally friendly option available.
