odor defense

Product descriptions typically say they neutralize odors at the source, break down or remove odor-causing molecules, use specialized technologies to block or minimize smells, or add an "odor defense" component in detergents to target musty odors.

Fridge absorbers: remove the front/back panels, place the unit upright inside the fridge or freezer, and replace it every 30 days. Carpet deodorizer powders: sprinkle on dry carpet, wait 15–30 minutes, then vacuum thoroughly.

Listings for fridge/freezer absorbers specify a 30‑day replacement interval. Reviewer reports for laundry boosters vary, noting scents that last for several days and sometimes up to about a week on clothes and linens.

The listed laundry odor-additive bottles specify varying use counts; examples in the data include 24, 70, 134, and 190 uses per bottle.
