You may have heard snorkelers and divers use the word purge valve when talking about cool features for their masks. There is an ongoing debate about how effective they are. One camp loves them and swears by them, and the other camp thinks it is gimmicky at best, and dangerous at worst. So what is a purge valve, what does it do, and do you need it?
For those unaware, the purge valve on a snorkel or dive mask is a one-way valve that forces water out of the mask when you exhale through the nose. In traditional snorkel and scuba diving masks, users have to manually clear their mask. This gets annoying really quickly if their mask is leaky. With a purge valve, you do not need to worry about this cumbersome process because water keeps getting vented out as you exhale through the nose. When it works, it is hands-free and hassle-free.
So why are some people so against it then? Read on as we explain the pros and cons of purge masks in greater detail below, as well as give our recommendations on the best snorkel masks with purge valve that you can get today.

Are Purge Masks Worth It?
As we mentioned above, this is a topic of an ongoing debate. For the most part, dive masks with valves are recommended by many divers. But there are also people who believe it isn’t worth it, at least for scuba diving, and that it should only be used for snorkeling or not at all. Why the difference in opinion? The best way to get a comprehensive overview is to look at it from both sides.
Advantages of Purge Valves
One Less Thing to Worry About Underwater
When you are in the water, especially if you are scuba diving, there are many things to worry about. People will pay a premium on their scuba gear if it can reduce the amount of work they have to do, and purge valves are no different.
With it, you do not have to deal with manually clearing your mask anymore. The water purges automatically as you exhale from your noise, and this is one less thing you have to worry about. You can then focus more of your focus and energy on the diving or snorkeling itself.
Hands Free Snorkeling and Diving
If you want to be able to do some underwater photography or videography, a mask with a purge valve is a godsend. Clearing your mask is quite difficult if you are also holding a big camera. You just want to focus on your next shot, and it would be a shame if you failed to capture something extraordinary on film because you were too busy clearing your mask.
Allows for Contact Lenses
A common problem with the traditional way of purging water is that the water gets into your eyes. If you are wearing contacts, this can greatly irritate your eyes. Even worse, it can sometimes wash away your contacts, and now you can’t see properly underwater. This is a huge issue when you are diving, so people who wear contacts should strongly consider getting a purge mask.
Perfect for People with Facial Hair
If you want to scuba dive or snorkel with a glorious beard and mustache, you may have to deal with lots of water leaks because the mask may not have the tightest seal with facial hair. There are ways to form a tighter seal, but the methods are not foolproof, and water may eventually seep in anyways.
With a purge mask, you do not have to worry so much about water entering the mask because it keeps getting vented out. Since people with facial hair have a higher chance of experiencing water leaks, this can keep your mask water-free even if the seal isn’t the greatest around facial hair.
Disadvantages of Purge Valves
Risk of Malfunction
The purge valve is typically found below the nose pocket. And when you introduce more parts to a product, there is always a chance that it can malfunction, and this would be especially bad if it happened while you were, hence why scuba divers recommend it only for snorkelers.
Don’t worry, it’s not the end of the world if a purge valve breaks while diving. Scuba divers typically carry a back-up mask just in case. If you don’t have a back-up, then you’ll just have to clear the water the good old fashioned way.
With that said, divers don’t want to purchase a mask that also requires a back-up mask. As some conservative divers have pointed out, more features just means more potential problems. If a mask has less components, then there’s less things to break.
People who are vehemently against snorkel masks with purge valves frequently cite how much they dislike cleaning the valve. As with any snorkeling and diving equipment, one must perform routine maintenance to ensure it is clean and clear of debris.
Just through normal use, sand will inevitably find its way into the valve. If the debris is not promptly removed, it could cause a leak through the valve, which results in the problem it was meant to prevent.
When wearing a mask with a purge valve, it becomes difficult to pinch your nose through the nose pocket. Though this is not a dealbreaker, numerous divers prefer to pinch their nose to equalize the water pressure.
How restrictive this is depends on the specific mask. If you need to pinch your nose while diving, then you will have to read user reviews to determine if it is still possible with that specific mask.
Which is Better?
In the end, it is up to you to decide whether a mask with purge valve is worth it. If you do recreational snorkeling, most of its disadvantages become less of an issue because you will not be in any trouble by the water’s edge. It is more of a hassle for scuba divers since a malfunction means they need to have another mask prepared and ready to swap at any time.
With that said, scuba divers may still want to use a mask with purge valve to clear the water without using their hands which is helpful if they are holding other equipment. The best way to know if it is right for you is to ask a diving buddy if they are willing to lend you their mask for a trial run. Otherwise, you could buy one online and return it if it doesn’t live up to your expectations.
Overall, if you like the idea of having one less thing to worry about while in the water and freeing up your hands, then it may be worth it for you to invest in a purge mask. We recommend buying from a trusted and reputable brand such as ScubaPro, Cressi, Aqualung, etc. Otherwise, you could be at risk of encountering malfunctions with a purge valve while out in the water.

Promate Dry Snorkel and Purge Mask
Many snorkel and dive masks provide excellent front views, but their side views are often lacking. This means missing lots of marine life or scenery, and constantly turning your head to check on your partner. The Promate Dry Snorkel and Purge Mask addresses this problem nicely, with its Avanti TL side-view that removes the vision breaks that multi-windowed masks have.
Additionally, in an effort to provide the best views, the channeled skirt design of the mask redirects bubbles away from the field of view. The purge system removes excess water that seeps in, but unfortunately it also makes the nose cavity very tight. The Promate Dry Snorkel mask was designed for medium to large-sized faces, but the nose cavity would be better suited for medium-sized noses.
With that said, the adjustable buckle, swivel, and hypoallergenic silicone skirt should provide ample comfort for those whose noses fit the mask perfectly. Once the mask has been adjusted to form a tight seal, leaks become a rare occurrence. The Promate Dry Snorkel features the Cobra snorkel, which keeps water from entering while simultaneously allowing air to enter and exit the tube for unrestricted breathing.
- Provides panoramic view without vision breaks.
- The channeled skirt is comfortable and keeps bubbles away from the lens.
- Cobra snorkel design keeps water out and air flowing.
- Rotating the snorkel opens the whistle housing, allowing you to call for help by whistling if in trouble.
- Not ideal for bigger noses.
- You must defog the lens yourself.
