Air Stone


Recommended Posts

Hey everyone

I'm new to this forum and actually don't even have a hookah yet. I'm waiting to move into my new house which is still under construction. When it's done I plan on spending a lot of time on the patio out back with my future hookah.

Anyway, I was shopping around and reading these forums and I saw the Heba filter and other DIY filters. I really liked the idea, since the whole idea behind a hookah is that the smoke comes in contact with water, which will 1) Cool the smoke and 2) Capture some of the particles. The Heba filters help this process by increasing the total surface areas of the air bubbles in the water. Basically, the smaller and more abundant the number of bubbles you can turn, the more effective the water is gonna be. This made me want to explore this idea further, and I realized that aquarium bubblers can be used too. I found this flexible air stone that would do the trick. Just throwing this idea out there since I can't try it for myself... yet.

edit:

If you're somewhat mathematically inclined, you can see that the surface area to be gained by breaking the bubbles down into smaller size is... a lot. The formula to find surface area is 4pr2, volume is 4/3pr3. I just did a quick and dirty (haven't touched math in a long time) and if you have one bubble of a radius of say 4cm, then split it into two bubbles of radius 2cm, you have doubled the surface area. Think of how much surface area you can gain if you used an air stone (very fine bubbles), I would say at least 10 times. The only issue that remains is the back pressure made by the air stone, but the product description says it flows without a problem. Oh, and also maintenance in cleaning it, since the pores are so small. Edited by BallentineChen

Welcome to the forum!

Looks kinda cool actually, but they look kinda long...I wonder if being that long it wouldn't increase the resistance when you draw...

I may run to my local Petsmart and see if they have them in the aquarium section. Give one a try...

BallentineChen:

not to be offensive but, 2 bubbles of 2cm in radius actually have less surface area than one 4cm in radius bubble.

4 cm bubble is 4x4x4pi = 64pi
2cm bubble is 2x2x4pi = 16pi x 2 bubbles = 32pi

What you're actually trying to explain is comparing volume to surface area and not radius to surface area.
2cm bubble has 16pi cm squared in surface area and a volume of 10.66pi cm cubed.
4cm bubble has 64pi cm squared in surface area and a volume of 341.33pi cm cubed.

so 16cm surface to 11cm volume = 1.45 surface area in squared cm per cubic cm
so 64cm surface to 341cm volume .188 surface area in squared cm per cubic cm

No offense taken, I meant to say that there would be more surface area for the same volume of air.

I think introducing a filter like this is going to damage the quality of your smoking experience, not improve it.


Why do you think it would damage the quality? I'm just curious. The one problem I see with the idea is that the Air Stone would be difficult to clean, and because it has small pores they may clog over time. Otherwise, the Air Stone doesn't really act as a filter, it just distributes the smoke more evenly into the water.

I'm really just gonna have to test this out when I get my hookah. So far my top candidate is the Mya Obelisk, or the Vortex. I plan on using it with company often. Edited by BallentineChen

Yeah, but your example, when worked out, indicates that 4cm bubbles have twice the surface area than 2cm bubbles which wasn't supporting what you were asserting.

Yes, I concede you're right. I forgot to point out that one 4cm bubble does not equal two 2cm bubbles, volume wise. It's more.

Jesus Mary and Joseph you engineers! Has anyone actually TRIED this yet and seen if in reality it works well or not?! I don't really care what the techincal details are just so long as it works nicely.

I have a HEBA and it works fine, but there is always room for improvement.

By the way...I am just curious as to why these Heba diffusers are about $1.50 here in the Czech Republic, but ten dollars in the states? We are not that much more cheap on anything, especially exotic items, and we have the accursed 19% VAT on top of that. Someone is making a fortune on these. I bet they go for peanuts wholesale...
