Is that always true? I know nothing about air freshener sprays (and do not use them), but I could imagine a spray which contains heavy particles that trap other

  >I could imagine a spray which contains heavy particles that trap other lighter airborne particles and drag them to the ground. That's how febreze is supposed to work: >As Febreze dries, more and more of the odor molecules bind to the cyclodextrin, lowering the concentration of the molecules in the air and eliminating the odor. If water is added once again, the odor molecules are released, allowing them to be washed away and truly removed.

    That's how Febreze works, I've looked into it too in the past. But the problem is that most other air fresheners aren't like that. They're just cheap scented mixtures that try to mask the smell. And it's definitely debatable whether they are doing more harm than good.

  It's definitely not always true. Car products like car bomb will kill the odor. You'll be breathing in the product for a couple weeks, but a couple weeks later it will be gone.

  Perhaps I should have said they do nothing to clean the air - even if they trap some odors. For that you need a good filter or ventilation. But most stuff I've seen used just is a stronger but more pleasant odor like citrus that becomes the thing you smell.
