The 3m particulate masks with the pink discs are a lot more comfortable, seal better, and last longer. It's more economical in the long term. I can handle working and walking/hiking with one, although I wouldn't want to run or climb up a huge hill in one.
You should chop the beard if you want a good seal. It sucks, but that's the deal. Ask anyone in the military who has to wear a mask.
The forever solution to heating and air conditioning in smoky areas (in my mind) is geothermal. It doesn't have an air exchange so you can keep the doors and windows sealed up, even running a filter inside if you like. We normally use a whole-house fan but it's terrible to spin that up when there's a lot of smoke out there.
My bad, I didn't notice the delivery options. Crazy that Amazon could have stocking issues from how big the wildfire problems are.
You can also try mixing up search terms for disposable/nondisposable masks and higher NIOSH ratings - there's one $20ish for an older 3M half mask model + 3M P100 cartridges, one and two day shipping available if I read it right.
I personally find P100's a lot easier to breath in as the valve is better (they are the bigger rubber style ones like this, make sure to get the pink filter kind as they are significantly lighter). I've been ok breathing in one for 2-3 hours while dealing with drywall dust and didn't find it that bad. Might also want to cross post to /r/bluecollarwomen as they will often have ways to handle the PPE question while pregnant.

No. Get an actual respirator that's rated specifically to filter out the types of aerosols/particulates/oils/etc you're going to be dealing with
Also, a portable spray booth comes in handy - they're between $80-$100 on Amazon and fold up into a fairly small size so you can store it when not in use.
Those particle masks will only help so much, in order to be better protected you need a good seal around the face.
Amazon prime one of these and stay safe!
If you believe the CDC can sell the average american on wearing a full face respirator whenever they go to the grocery store, more power to you.
Also, I've worn one of these. The materials are cheap, the straps fall apart, and the filters aren't certified. A proper mask is around $30 for a half-face elastomeric, or over $150 for a full-face respirator.
How is this one?
3M(TM) Half Facepiece Respirator Assembly 6291/07002(AAD), Medium, with 3M(TM) Particulate Filters 2091/07000(AAD), P100 [link]
I couldn't find a full face respirator at my hardware store, but I know they sell them on amazon.
Hello fellow Oregonian! Here in Eugene it got up to 430 air quality index ... that's "Hazardous"! Crazy bad smoke.
I've run up to 150 air quality index (I ran 18 miles in the orange zone.) Made me cough a few times during the run, and I felt like I could feel it impinging slightly on my performance. It wasn't pleasant, but wasn't super bad.
Today I went for a run in this half-face respirator! I looked like a Fallout character, and it was pretty tough breathing through, but it worked for a 1 hour easy run and the air quality was perfect! I wouldn't try running harder or much longer with that thing though.
You want this kind of mask (Amazon is half the price of Lowe's/HD): [link]
The most important thing is not to create dust by crushing, pulverizing or sanding tile or mastic adhesive. Tiles are mostly non-friable (friable means easily crumbled, like a cracker) so your risk of exposure is low.
3M provides a HEPA mask which I've found to be great. A dust mask won't work, you need a HEPA.
I use this one from 3m LINK whenever I am going to be cutting more than one board. You should definitely use it for cutting plywood. The glue and resins in plywood is toxic.
I also use it for finishing.
You can get different cartridges for different projects.
Id snag one, for work when we are working around contaminated dust they don't let us use unfitted masks. They help but don't really block that much because the sides are usually open and allow air in. linky
Clean air only costs $15 dollars. You can afford it.
These suck donkey balls to breathe through, especially if you're doing anything that remotely raises your respiration rate.
Get one of these instead.
N95 can work. Or get a 3M half-face respirator with P100 filters. That's what I used during my time as a fire lookout.
You definietly want a respirator instead of a mask. Silicates are nothing to fool around with. You don't even realise you're breathing them in, then over time you'll end up with silicosis. A good respirator is cheap compared to not being able to breathe.
This is what I use. It's a bit overkill (P100), but for 30 bucks I don't care.
This is basically what I would be using.
Interesting! At least one of Baianda's respirators is found on the NIOSH CEL, even if this particular respirator might or might not be.
Still: This respirator kit currently costs US $25. You can get a 3M 6291 kit for slightly cheaper.
I don't think it's worth spending US $25 on a Baianda kit which costs more than a 3M kit.
The Powecom 3900 kit costs € 12 (about US $14), including slow shipping to the UK. The kit's attractive price, in my opinion, makes it possibly worth consideration.
The Powecom 3800 kit is even cheaper, at € 5 (about US $6).
If the Powecom filters offered just 90% particle filtration efficiency, this wouldn't be great. But it's very possible that the filters exceed the KN90 minimum requirements by far.
> Powecom basically just rebrands unbranded 3M/respirator clones mass-produced in factories. There's like 20 different brands with difficult to pronounce names in China that sell rebrands of the exact same masks.
If Powecom is willing to attach their name to the products, surely they feel that the products measure up to Powecom's usual quality standards. We know that Powecom products aren't wonderful, but that they're inexpensive and, IMO, okay.
Some people would differ, and think that they're of poor quality.

I found a Medium sized one here:
Staying in my basement pretty much as much as possible. When I do have to go out for any extended amount of time I use one of these bad boys.
Sure! This is similar to mine. The filters are replaceable and you can get different ones to suit your needs (like if you need it for construction, etc.)
I ordered a similar mask for $20 with a set of filters included and will have it on saturday
Here's the P100 mask I bought, is this any good? https://www.amazon.com/gp/product/B000FTEDMM
If you get a respirator they are cheep and will filter out like 0.2 micron partials. These filters will last forever unless exposed to organic compounds. They are fairly cheep. Your looking at under $20 for like 5 or 10 years of use depending on how you use it. Obviously you can buy a more expensive respirator with more filtration ability if you need it, these are just suggestions.
Like any safety gear:
This is what I use, but I also use it for sanding bondo, painting (with different filters) and working with cutting/grinding G10 and fiberglass which is way nastier than wood.
If you don't want to bother with a full respirator, the P100 is a good doctor-type cloth mask
If you really look into it and are the paranoid type though, you'll realize your chance of trapping any of the 30nm and smaller dust particles are basically 0, which can be a problem because they're the ones that get deep into the lung tissue. But anything like the above will work fine for trapping the bigger stuff. People spend thousands of dollars on systems to trap or get rid of the smaller particles, but unless you're a serious hobbyist, ie: exposed for many hours a day, it's overkill. Source: Working on a dust collection system for my grinder with exterior vents and basic filtration. It's a pain in the dick.
Best way to minimize the risk? Do it outside. Dilution is the solution for pollution. This isn't a post to scare people so much as remind them that literally everything can be hazardous in some way. Just take regular precautions to minimize the risk and enjoy what you're doing.
Bear in mind I'm not that experienced either, but that's a non reusable respirator, and yeah it would probably do fine. But you would do well to get a reusable one like this or this. There's no need for a full-face respirator like this if it's what you're asking. Just be sure to buy the cartridges also and get the right ones. I don't think the lingering fumes would be that big of an issue with a spraybooth. The respirator imo is just to protect you from the overspray during the painting process
I use this mask with these filters. It works well :)
3M's 6000 series dust masks are awesome. Super comfortable, and the first dust mask I've ever had that actually works. The soft rubber gasket is incredibly comfortable and has a foldover design that flexes to make a perfect seal against your face. The exhaust vents aim down, so you don't fog up your glasses. The head straps are comfortable, adjustable, and super easy to clip on and off. It's low-profile enough that it doesn't obscure your vision, and shouldn't interfere with goggles either (unless you've got some kind of super bulky goggles, I guess).
The whole thing is so easy to put on and so comfortable, that I pretty much don't do anything in the shop anymore without wearing it. And I'll tell you: I have definitely noticed an improvement in my general respiratory health since I got the thing. For the price--less than 20 bucks from Amazon--it's a total no-brainer.
I use these filters with them, which do an amazing job not only of keeping dust out of your lungs but also the smelly vapors associated with the various finishes and solvents we tend to use in the shop.
Dude, seriously– this is how you get Aspergillosis. Always have a respirator on you at ALL sites you go to. It's better to have it and not need it, than need it and not have it.
Get these and they'll be fine. As long as you're not stupid or working with it day in day out then there's nothing to worry about.
I actually have to wear one of these when I mow because of allergies and it works great.
