Do these filter out car fumes, perfumes and other CHEMICAL pollutants and mold?

I have sensitivities to chemical odors and they do not work for me. These are mostly for filtering submicron particles such as dust and pollen. If you want to filter chemical odors you need something with charcoal in it. I use "Air-Aid" Emergency masks. They are lightweight and have charcoal embedded in the fibers. They are use by police and fire departments and have been tested against chemical and biological weapons. Since I am very chemically sensitive I layer 2 masks on top of each other, but they work for me. Hope this helps.

I don't know since I can't breathe through two at a time. There wasn't much info in the packet, either...

Yes. The engine air filter is specific to the engine intake and has the firm rim to prevent unwanted materials from passing through leaks and it also has a wire mesh to prevent crumpling. The cabin filter is simpler.

Yes, the odor-reducing filters should have whitish splashes or blotches on one side while the regular prefilters do not. I would guess the whitish substance to be zeolite which will attract & trap unwanted particles and odors.

Yes they are HEPA filters. However, I've had allergic reactions using the 3M mask with these filters, and I don't think I would if the mask were truly removing 99.97% of the allergen. Some allergens leak through, somehow. These filters are the best I know of to filter out allergens, but I've had many allergic reactions to animal dander right through the filter. And to some kinds of mold. Either the filter itself isn't very good at filtering out some allergens, or other parts of the mask leak somewhat.

I think they mainly just control odor but they might remove some allergens because of the charcoal filter. The Hamilton Beach website might give more details.

The filter is designed to eliminate particulate matter, ( dust, pollen, paint over-spray, etc.). It will NOT offer protection from Carbon Monoxide.

I would say no. Respirators that claim vapor filtering have activated carbon/charcoal cartridges.

These filters are great and safe for even the smallest of wood and dust particles and are lightweight so are practical for long hours of wearing in the shop. What they cannot filter are solvents and paints. Tried with spray paint the odours and fumes can be smelled. The carbon based typical dual layer cartridges are safe for most solvents, fumes and paints. There are charts online to at 3M to learn more specifics.http://multimedia.3m.com/mws/mediawebserver?mwsId=SSSSSuH8gc7nZxtU5x_9oxmZevUqe17zHvTSevTSeSSSSSS--&fn=ReusableRespBrochure.pdf

No. These are strictly particulate (i.e., 'dust') filters and provide no protection from organic or inorganic vapors. Google "Selection Guide for 3M Reusable Respirators" for recommendations.

We bought the filters to remove sediment, didn't have a problem with any odor. If I had to guess, I would say that these wouldn't help with your odor problem. Maybe there's a filter that would help with odor's along with sediment but i'm not sure.

From my experience yes they are as effective. Some people say the baking soda helps freshens the air. You can always sprinkle a little baking soda on them if you like since baking soda is a common kitchen item. I don't think baking powder would work since that's a different thing for making baked goods rise in the oven.

I am not qualified to answer that question. You should ask the manufacturer of the filters. They would be best to know what their filters are made for.

Absolutely not Mr. Grossman. I have detected zero perfumes, odors or smells from this filter. Perfumes cause my wife to have migraines, so this fact was critical in my decision to purchase this filter.

Absolutely. This is the same type of fiber poly filter used, but w/o the carbon coating. The carbon coating actually restricts the size of particles allowed through, making it more effective. I use these in concert with my car air filter to keep the road diesel smell down. Are they Heppa filters...no. For this price point you are not going to purchase a Heppa filter. For what it is, it works well, keeps major particles out of the air stream and kills odors for about a month. I'd buy it again.

No they are particulate filters. Good to 1micron. Would likely stop most of paint pigment but not the vapour. You would need organic vapour cartridge for this mask as well.

Yes, but the ones I received had very little smell compared to the ones I purchased from an auto store. I placed one in my car with the wrapping completely removed and still couldn't smell it.

These are meant to filter extremely small solid particles. Key word: "solid". Pollens, pet dander, micro-dust, etc.. For most hazardous fine vapors (i.e. gases) and potentially-hazardous liquid materials that are sometimes used/applied as "mists" (lacquer paints and insecticides are two of many examples), you would want to use filters made of a different (finer, tighter?) mesh material.
