Do the valves on the mask resist both inhalation and exhalation?

Two are restricted out and the center is restricted in so you have a good balance on strengthening your lungs and my mask is working fine for me

These are surgical masks with a cover sheet to protect from splashes. They are not truly reusable, although I will wear one more than once. There is always the risk of contaminating the inside of the mask from materials that would gather on the "cover" when taking it off and on. I find that these are durable and comfortable and without overwhelming odors. You may want to look for other masks which have a valve to allow the discharge of breath if you are exerting yourself. Nearly all masks are meant for a single use. Beyond these are actual haz masks like they wear in the movies with replaceable filters and hard shells capable of disinfection.

There is resistance while exhaling, however, the emphasis is on inhaling as this is a lung "Expander". You can always varying the amount of work you want your lungs to do by covering or opening the small open "arrow" at the side The more you open the easier it is; close and it gets more difficult. I hope this helps.

Yes, although you DO need to always wear a respirator (dust mask in this case) regardless of having any booth. I just did a German Panzer IV J and used pastels for my weathering effects. I turned out beautiful, and the booth did a great job at cutting down on the dust in my hobby room to zero.

I have no problems breathing with it. I tried the Sly Profit before this but I had a hard time breathing on that one. You can definitely hear yourself though with this mask compared to the profit. I hope this helps.

No they are particulate filters. Good to 1micron. Would likely stop most of paint pigment but not the vapour. You would need organic vapour cartridge for this mask as well.

Yes, they are pleaded. However, pleaded is only one minor factor in a filters efficiency. Far more important is the micron rating, and whether or not the filter is electrostatically charged.

Hi. I went through the same thing and checked the 3M site. For the mask you may buy different kinds of filters. The one that is for dust, like for a woodworker, has a filter inside that looks like a cars air filter. The one for chemicals has a different filter inside and you may use these pre-filters. Put one of each cartridge facing up. They fit into the ridge around the filter and a cover keeps them in place. Hopefully I've been reasonably clear otherwise feel free to ping me again.

I do not believe so, I think it has to be a Phillips Respironics Mask in order for the parts to fit

When I first used it I kept breathing in water...eventually I realised I needed to fiddle with the valve, the inner bits were just in the wrong place. After that ... Absolutely no issues. Good luck and happy swimming.

Yes it does, but not exaggerated. You can use a protection mask while pouring it. It's so volatile that it dissipates fast.

You have to squeeze the holes just right while you are blowing the air in. This keeps the air from coming back out between breaths. You have to pinch the valve so that it opens and the air can go through. Hope this helps!

Yes they do, I can't remember the number for the item, but it should say it on the mask itself, or in the description, but I checked before I bought the mask and they did sell the filters

I just used a paper mask with metal nose clamp... It worked for short exposure. You probably need respirator if you do it more often.

They can come off and you can change the little images with something else within the respirator. I didn't notice until it popped off one day.

I ordered the mask and valves seperate. But you can buy just the mask, the one I ordered came with complete set of valves already and the valves I ordered seperatley came with a complete set(different altitudes).

No, I don't think so, as it only has one thing to manipulate: the on and off switch. However, all the inflatable items I have used happen to have a way to fully open the valve and therefore deflate in no time.
