Disposable Respirators.

Where's a good place to buy from?

Do you mean fiber type dust mask's that fit over you nose? Any cheapo depot, tool supply, paint store etc should have them. Anything else wouldn't be "Disposable".

If you plan on using them for cleanups IE insulation, feces or in a confined space, I would strongly suggest you go with a full or half face respirator. The full/half face contour to fit your face, them disposables are junk. May seem like a pita to wash and clean them after every use, but if you're doing this as a business that time should be included into your price on jobs.

Thanks for the help, TDHP and BidBob.

Np run, we all have our own ways of doing things that work for us. I used one of those in a pinch years ago in a blown in insulation walk through and it was as if I didn't have anything on. Might have their place but imo not dealing with the conditions we encounter on jobs. Decent ppe gear regarding half face respirators go for $20-$25, full face $140-$190 can be bought at grainger and stores alike. I don't skimp on ppe. I'd also invest in tyvek suits

I wear my full face on every cleanup and walk through if it involves insulation. Proper storage and cleaning and they will work and last for years. Mine stays in the truck and is ready to go when needed.

I have both a full, and half face on my truck.

Any tear outs get pre filters over the cartridge too. Its shocking how dirty they get.

The important thing is the fit. If it leaks air it's not really working.

Can never have too much ppe.

Definitely agree with TDHP and Eaten,

Though we keep some light duty simple "dust masks" around for a quick look or simple inspection, full face and half face with filters are always with me.

Just in terms of airborne insulation particles in a basic attic even one without much wildlife issue, if you look in the dark at what your light sees, the tiny fibers
floating and the ones too small to see are going right into your lungs and there are reports on how many of these insulation bits once in there ain't comin out.

We've always used northern safety, simple, online, etc..but do have a grainger and use them too, any good safety source has what you need and cheaper than
if you can find at local stores and with better options and fits.

On a side note, do consider talking to your doctor and getting fit tested where available locally so you know you are good to go on your health while wearing one.

Try both out, when you're clearing your throat out 10 minutes into the job hacking up a lung, you'll realize them dusk masks are a no go. Really no substitute when it comes to respirators, especially when you get moving in these spaces.

Great pics of the flashlight micro debris!

Insulation removal is also shocking when you look at your replaceable filters after being in the space working sometimes less than 30-60 min and they
are completely covered with a layer of what would otherwise be in your airway!

No disposables because they are not good enough. They are better than nothing. Good 3M brand or whatever are inexpensive insurance and protection.
