Delta Says No To Masks With Valves; Will Offer Complimentary Mask

There is an interview for persons with medical conditional

This make no sense as the article talks about masks with *exhaust* valves.

The issue is many of the cheaper N95 mask valves have no filtration system built in. A proper N/K 95 mask with proper filtration is expensive. You should see the looks I get wearing mine around. Its a pro model that was used during paint shop days.

Here, here to the comment about people wearing masks UNDER their nose. That COMPLETELY defeats the purpose! As for valves, you have to understand the rationale for requiring masks in the first place. The idea is to protect others from you, not to protect you from others. As a physician, I’ve ordered (or tried to order) tons of different masks in the past several months. There are N95s that are approved for use in the OR, but none of those have the simple exhaust valves, because in sterile situations, the need for protection is a two-way matter.

There is probably a low risk with a face mask with an exhalation valve under normal breathing. However, the force of a sneeze or cough is more powerful than a normal breath and according to some articles these exhalation valves can allow aerosol droplets in sufficient quantity to pass through even charcoal filtering and pose a risk to those nearby. I think you are correct that Delta has done their research. What a conundrum this virus has caused for everyone?

If Delta is making this call it should and must be backed up by a mandate from the CDC. If we are being put through these changes based on "science" and it ALL needs to be standardized and that needs to come from the CDC not individual airlines. They need to be clear about the mask types, how to wear them (including below the nose-shouldn't you be thrown off the plane for that too?), how long you should have them on before changing them out, everything!!! This is all slapped-together science and it's got to stop! Hopefully once the vaccine comes all of this will go away and we won't have to deal with this anymore-yeah right!!!

That is because A: the 3M masks are proper and have filtration, so CDC will say little to them..actually sometimes they say little to anyone when they should be saying a lot more.
B: Look how long it took them to flip from "the World Health Organization and the CDC initially advised against wearing masks, saying there was little evidence that it would help prevent people from getting sick." to "Now, the CDC encourages all people in public to wear masks where social distancing measures cannot be maintained,"

Give your head a shake and do some basic research!

“ A Centers for Disease Control and Prevention representative told Reuters that carbon dioxide, indeed, will collect between the mask and face but not in dangerous amounts and certainly not enough to cause hypercapnia. A mask is designed to trap viral droplets, much larger than tiny carbon dioxide particles. A mask, either N95 or cloth, cannot trap all carbon dioxide particles — they either go through the mask or escape along the mask’s perimeter.”

Actually valved masks are very in-effective. There are 2 types of N95 masks and health officials say do not wear the valved units. They allow unfiltered air to escape.

Delta isn’t selling middle seats and have also cut the number of passengers allowed. Same with Southwest.

The whole reason for the masks is due to not being able to physical distance properly on an aircraft. On international flights, middle seats are vacant to assist with distancing.
If you do not like Delta's mandatory policies, find another airline.
