Here's a chart to determine the type of filter you need based on the job you're working:

Hope this helps
Edit: I used "n" ratings in my description, whereas the included filters with this mask are "p" rated (which is why they are pink). The only difference there is that the "p" filters are resistant to oil, whereas "n" filters are not. Their ratings are otherwise the same.

So what is this good for? Is it good against COVID? What about against general home improvement projects dust?
Most I've seen are falsely labeled anyway. Not saying they don't work at all, but if you've worn both, you'd know there is no way the kn ear loops can provide a good enough seal to your face.
Of course If you have facial hair, you might as well just use a cloth mask as everything will just leak around anyways.

Ag is acid gas
P is strongly resistant to oil, 100 means filtration level (99.97 .3 microns absolute). It will filter particules smaller than .3, but it's not at 99.97 percent.
You don't need this cartridge for covid, but will work for covid.
Once opened, the vapor absorbing component will absorb stuff out of the air; that part will then stop working as it is saturated. The filter part will continue working until it is physically clogged. If using only for general respiration, that could take weeks or possibly a few months before performance is degraded.

Those n95 are at best kn95s.
Btw there are tons of unscrupulous individuals who sell knock off filters for 3m as well. And they even have similar looking boxes, halogeaph sticker too.
As for the particulate filtering aspect, replace when breathing becomes difficult.
Again not the preferred cartridge for covid. It's heavier, and actually has slightly less filtering capacity (not effectiveness) than some of the other filters. 7093s have a hard plastic for a seal check and can be wiped down after use. These the filter point directly out, which means they are subjected to possible direct impact and damage. (not that common)
I actually use a set of these when cleaning with chemicals. after every use, I take them off, put ina zipper bag. I get a few months that way.

I'm assuming I can just buy a different catridge for this respirator. Also, really appreciate the information. Thank you!!
just curious. what tasks are you doing for "home use" that really require this.
I've used the homeowners version of this work with stains, thinners. fiberglass (boat and car). I actually find it more comfortable than paper kn/n95 masks with thin straps. plus I sound like Darth Vader. Plus if you are wearing safety glasses, the venting on thus helps prevent fogging. paper masks are horrible for that.
