is there a purge system in the mask, as well as in the snorkel?

No, and the one on my snorkel leaks so that I have to forcibly purge it every 4-5 breaths. It's very annoying.

No it does not. Just let the person filling the tank that it is new and needs to be purged. Its a quick and simple process.

1. No. this mask just a mask with a socket that you can fix GoPro on it. For anti-waster case, you can buy it from GoPro, I remember it's already included in the GoPro 3 package.2. not understand your question, what your mean is what's the size of this mask? i think it's a free size, you can adjust it to suit for your face. But for how to select a suitable mask, inhale deeply through your nose and let go of the mask. the mask should stick to your face without you holding it.here is a reference for you, http://scuba.about.com/od/masks/ss/HowToTryOnAScubaMask_4.htm

This particular design is not washable. Wiping it off doesn't do much to remove heavy accumulation particles, but immersion in water ruins the mask's breathability.

I am not sure, sorry. This is the only mask I have ever purchased and I am happy with it.

No! I tend to run out of wind before my arms give out. the snorkel lets me focus on stroke and not have to worry about getting air. The tube is a bit long, but breathing through it is not an issue.

No. It cleans the mask, attached tubing (short and long) and humidifier water tank that is enclosed in your CPAP machine.

Not really. The paper bags tend to "spit" a little when you take them out just from the bag shifting and air coming out. If the stuff you're vacuuming up is that bad, you should be wearing a respirator as well regardless. Also, they do sell a different kind of bag for use when vacuuming toxic materials...it's basically the same brown paper bag but within a black plastic bag as well that then has a sealable mouth for proper disposal. I haven't used it before but I suspect you'll still have the same problem when removing/swapping it out. Best bet, get the plastic bag and wear a respirator as well. Good luck.

No. There is no purge valve on this tank. Just a simple wheel valve, open or closed.

I would avoid this. I had to return ours as the mask always leaked for both myself and my daughter. I think they are simply too small and cheaply made. Worth the time to go to a dive shop and fit a good mask.

The mask is no different from any other scuba mask except for the attachment point for the GoPro. I used it to snorkel with whale sharks a few weeks ago. A snorkel will attach to the strap on either side. I love this mask. Comfortable and much easier than trying to hold the cam in your hand. You DO have to be cognizant of moving your head too quickly if you want a good quality video, but you're going to have to edit footage anyway.

Yes. The system is patented here is the Patent number (PAT.8.590.533 B2) To learn more go to this page and scroll down and scroll down to the section titled "The Science Behind The Mask"Hope this helps!

AFter a few weeks of using this to lap swim, the purge valve leaks horridly. It makes the snorkel worthless and scary. I cleaned the stupid valve and super glued it!!! Why is the valve even there??? It is a flimsy, light weight plastic that will leak over time.

Not in the traditional way that you think, in that there's no valve. The whole mask is the filter. When you inhale, the air filters through the non-woven microfiber material.

Yes, I used this on our last cruise for my passport. I had no water leakage problems while snorkeling.

Snorkel is not included... it comes a mask (or course with its own strap) and its screw to fix Camera Housing and its protection bag...It is fun, if you do not expect a pro video while scuba, because bubbles interference...or may be just to snorkel it will do great job...

No the mask, hose and water tray is cleaned by the ozone. Unless you have some kind of dirt that has gotten on your mask would be the only time I would use soap and water. Ozone or O2 is used in many hot tubs and some pools. I am very very happy with my cleaner and it smells fresh and clean each night. I am now wanting to get the travel size SoClean. You won't be sorry you bought this product. Hope this helps. Ann
