Thanks in advance for your help!

Wish I had that option. This is for my own personal home use, and I already have purchased several other new ones to avoid cleaning. Now I have a bunch of these that are all dirty, and need to be cleaned. Picked up an Allegro cleaning kit (double sided bucket, special cleaning/disinfecting soaps/solutions, special brushes/cleaning tools) to make this as easy and fool-proof as possible. All of these masks have gotten so sweaty (and some have grease/oil on them) that they make me kinda sick from breathing through them. So instead of running up to Home Depot for $20-30 a pop, I've decided that I need to get it over with and clean them myself, lol.

Yeah, they're not cheap but for the price they're a good value. Next time around I'll order the 7000 series versions online instead (stores generally don't stock them, even though they're not that much more expensive) - the face seal is better, and supposedly the overall quality/comfort is better. I like to have one set aside for dust use (w/P100 filters), and another for chemical use (w/VOC type filters). I find that the P100 6000/7000 series respirator filters (the pink colored ones) are basically the same price as a disposable 3M P100 (#8293) mask, and the respirator is MUCH more comfortable to wear (and prob filters a little better due to the face-seal). I keep a couple of the disposable P100 masks in my portable (in-car) PPE/emergency kit, since they're smaller, simpler to use and inherently aren't as sensitive to extreme temperatures during storage as an actual respirator. But for in-home/shop and/or extended time period use, I always prefer an actual respirator over a disposable mask.

***EDIT***

Ok, finally found a video on the web that shows how this comes apart. I guess you just have to tug on it hard and it pops off. I suspected that, but didn't want to damage anything if it wasn't supposed to come apart like that. Video linky below:
