3M P100 Respirator Cartridge/Filter 60923, 1 Pair, NIOSH Approved, Helps Protect Against Organic Vapors, Acid Gases, and Particulates, Magenta, Yellow

If you're here, you already know M3 P100 filters are the way to go in terms of mask filtration, particularly when coupled with a traditional M3 half-face mask. This particular model is designed to filter a variety of particulates and gasses, protecting your lungs from all listed environmental hazards, making it an all around solid choice regardless of use-case. Value wise, you don't want to compromise when it comes to your health, so knock-offs won't due. Comfort and fit is irrelevant here given these are standardized. What matters is the fit of your mask, so do your research when it comes to the various sizes and suction reliability of M3 masks in general.

I've been buying these for years. Absolutely needed if you are doing spraying, hardcore cleaning, etc. About the same price as the organic vapor cartridges, plus acid gas protection, which is good coverage in case you don't know all what you'll be using them for. Save these in between uses by putting them in a plastic bag, and if you are just doing operations that create dust use the cheaper 2091 type filters.
