Last summer, my fiance and our sons spent a holiday weekend on a fishing escapade. They returned home with a cooler loaded with fish, which I then stashed in the freezer. Every one of us completely forgot about the fish until some months later on. My fiance asked if I would cook the fish for supper that evening. Although I soaked the fish in milk for multiple hours,and marinated it in sweet spices, the stench was terrible. After smelling the aroma of baking the fish, none of us could bring ourselves to eat it. Every one of us ended up making ourselves sandwiches and throwing all the fish in the garbage. Unfortunately, we could not eliminate the odor. Since it was winter, the apartment was sealed up tight plus the furnace was running. With outside temperatures so cold, none of us could just simply open the windows. I tried cleaning with disinfectant, using room freshener aerosol cans, setting out solid air fresheners, plus burning scented candles. Nothing could disguise that unmistakable odor of fish. I became convinced that the stench had gotten pulled into the ductwork plus spread throughout the house. I finally contacted a local Heating & A/C company to inspect the furnace plus HVAC ducts. The Heating plus A/C company worker explained that any buildup of contaminants within the HVAC ducts can trap smell causing particles plus add to unpleasant odors. Along with a thorough cleaning of the components, he recommended that I invest in a whole-home air purifier for our apartment. The air purifier works with the furnace plus cleans the air in the home up to seven times hourly. It traps pet dander, pollen, dust, bacteria, mold spores, plus also helps to eliminate nasty fumes and smells. Because of the air purifier, my apartment home finally smells fine again. It also stays cleaner, feels much fresher, and healthier, too.
