Yes it is.
I have used this type of mask over many years whilst working in a sheet metal environment.
The valve allows you to breathe out, but it prevents you ejecting spit/particles in a forwards direction.
The valve then closes when you breathe in, forcing you to breathe through the mask material.
They are primarily used for preventing large dust particles entering your lungs, not any type of virus.
And is 2 metre social distancing enough........https://www.reddit.com/r/vapetricks...ease_enjoy/?utm_source=share&utm_medium=web2x
Ok.
So, it doesn't stop you ejecting particles.
So, it does protect you from dust particles - and presumably droplets containing viruses.
Maybe, but -
is the wrong way round.

It seems a better mask based on the science is one made from a hybrid Cotton/ flannel or cotton/chifon - not sure as to the breathability but having a valve then defeats half point of wearing it. I believe the CDC does not recommend valved mask as it doesn't stop transmission.
On top I think the advice is to wear a washable mask that you can wash daily, both better on your back pocket and environment. A simple wash with some soap for 30s to a minute should suffice I assume rather than putting the laundry on daily.

The OH got one of these for me from her work place.

The spec says that it can be worn continuously for up to 28 days (presumably for 8 hours a day).
I get what you are saying about breathing in microbes but I kinda don't. If the microbes are being trapped at the outer layer, even as they build up in time, won't they still be trapped on the outer layer?
Personally, I only plan to wear mine on the bus so that the fellow passengers don't treat me as a pariah. I remain unconvinced that masks will make that much difference with regards to rates of infection. I see a lot of people resting their mask under their chin or on top of their heads when they are not in close proximity to other people. I wonder how much of a false sense of security they provide.
I have been using public transport troughout the whole lock down. I can only recall one incident where someone coughed, and that was only a small puppy cough. To me that suggests that people have been self isolating, it could also be the case that social distancing has resulted in far fewer people getting the flu or cold. I guess that may change as hay fever allergies kick in, in which case the masks may help reduce contaminates from asymmetric Covid infected people.
With regards to my mask, I just wanted a better quality mask that I could use for work as well as travel and that was more comfortable than the cheap cartridge masks I currently have.
I’ve just ordered a pack of 50 of those blue disposable ones - only work out to 41p each.
OK
It stops you ejecting particles in a forwards direction, as against an unprotected cough or sneeze, which is its purpose.
Use of the word presumably means you don't know, and are now guessing.
A Virus is even smaller than bacteria, and will get through any material, that lets you breathe through it.
No it's not.
Scientists have already said that masks on there own, do not protect you from Covid 19
But the virus has to "piggy-back" on a droplet, to get to you. The mask stops the droplet.
And, you're thinking about it the wrong way round. The mask that the public is meant to be wearing is not to protect the wearer; it is to protect others from the wearer. That's why the advice is to wear unvalved masks.
Also, if the advice was intended to protect the wearer, you'd be being advised to wear goggles / a faceshield as well.
Here is a useful tip for improving the seal of the common "surgical" type of mask.
Feel free to pass it on.
Feel free to pass it on.
So what? You only introduced direction afterwards so it does not stop you ejecting particles, does it?
No it isn't; it is a dust mask.
So, no point wearing any mask, then - let alone one with a large hole when you exhale.
Yes it is.
Maybe, but that was not the original query.
You said a flap which opens when you exhale stops you ejecting particles.
A large hole does not do this.
I don't know what you are missing. I shall say no more.
You need to read my posts again, that is exactly what I have been saying.
I have used these masks for many years, they do not propel any particles in a forwards direction, which is the point.

Some FFP1 masks will help or FFP2 but those available have valves for when people breath out which defeats the objective. Most of the blue surgical types are pretty useless but may be classed as FFP1. I know that some I bought of Amazon ages ago are totally useless.
Problem - just try buying some. An FFP2 with valve is of help to people who haven't caught it but no help to prevent some one with it from spreading it to others or into the environment.
Some FFP1 mention moisture. Some FFP2 don't have valves. Main problem is buying them. Seems the USA is mopping them up and others.
So if every one wore either and FFP1 or valveless FFP2 when indoors and not where they lived it would help prevent over 65's and others from catching it. There really isn't that much of a need to keep changing them if all wear them. Virus can't last more than 3 days even on plastic so another option to reduce numbers. Maybe they can be ovened at 100C, another option. Maybe a blast in the microwave would kill them - they need the tiny drop of water they contain.
Found some I hope

Cost around twice what they would usually be but can be reused.

Is the valve removable to allow cigars in?
