I bought these for painting and I don’t smell a thing when I wear my mask with these filters.

I've been doing a ton of painting on a house and the filters I had before these probably should have been swapped out sooner. Comparing these to OEM filters I can say they seem to work exactly the same. There doesn't seem to be any strong odors than with my previous filters, and the breathability feels the same.I don't have scientific equipment to actually test if what I'm experiencing or not is indicative of how they're filtering out particles but in all ways these definitely seem to do what they claim and seem just as good as OEM. The filters came in a the vacuum sealed metallic bag as indicated in the listing and for mine the seal was still intact when I received them which is great. Filters like these need to be stored in airtight bags or they expire much faster when exposed to open air.I'm happy with these they definitely seem to work as described and price point is extremely nice

I ordered this as a back up set for my respirator. They came in an aluminum vacuum sealed bag, which is where they will stay until needed. The bag will keep the filters fresh and uncontaminated until then. There is a use by date of 2028 printed on the label. I like the long shelf life because these filters are supposedly good for about 220 hours. So even If I don't use my respirator that often, by the time the current filters are no longer usable, these will still be fresh. I see that a lot of reviewers only like the leading name brand and I don't question their decision - it is their health, after all. However, the off brand filters I've used have worked just fine and expect this set will too. I'm glad I got them.

Firstly, I love that these are pink. These came very nicely sealed. So much so that I could hear the air being sucked into the packaging when I opened it. They fit perfectly. A little tricky to get them on but I think that is the design of the headpiece not the product itself. I used these while doing some sanding and was able to breath fine without inhaling all the dust. When it comes time to change, I'll be ordering more.

I tested these for a bit on both my half and full size 6000-series masks (6200 and 6800, respectively). They fit nice and tight, no odors were detected and I sealed them back up in ziplock afterwards to preserve for the next use. If I have more feedback after more usage, I will update.
