In my opinion this atomiser is kinda update of the old one. With the addition of second membrane, I believe they are trying to break down the bubbles, that have caused the mist in the aquarium with the old one. The other marketing trick is the transparent body, which is fancy and will allow you to "see the CO2" - from this I assume that when you connect it to the filter it will fill up with water, as there will be not much pressure. Then when you switch on the CO2 the fine bubbles going out from the first membrane will be defused even more through the second one. That is why the needed pressure is so high- to be able to push the water with the CO2 dissolved through. I cant figure out, how the body will keep filling up with water, as the pressure will push it out....
