Baking soda is a chemical base that only neutralizes acidic odors — it does nothing to alkaline or neutral volatile compounds. In a torn-corner box it also has almost no surface area, saturates within days, and can actually re-emit trapped odors. Charcoal bags are better, but still finite sponges: once full, they fail silently. Cynora uses catalytic decomposition — odor molecules are chemically broken apart and converted into water vapor. The catalyst is never consumed, so it never saturates and never stops working. It's the difference between a sponge and a reactor.

This is the most common frustration we hear — and there's a real reason it happens. Refrigerator odors are airborne volatile gases that circulate through your entire fridge's atmosphere, get absorbed into the porous plastic lining, and recirculate through the fan and evaporator coils. When you scrub the walls, you're cleaning a 2D surface while the smell lives in a 3D atmosphere. Cynora works with your fridge's own airflow to treat the circulating air itself — which is where the odor actually lives.
