Fresh air is one of the greatest ways to get rid of bad smells in the house, because the smells can be carried out of the open windows and replaced with clean air. In spring, summer, and fall, open a few windows throughout the house. To create a breeze, open windows that are on opposite sides of the house. In winter when it’s not possible to keep the windows open, open a window for just a minute to let in some fresh air. Fans are great for boosting the refreshing power of clean air. When you have the windows open, turn on ceiling and standing fans in the house to help create a bigger breeze and get the air moving. Sunlight contains ultra-violet rays, which have the power to kill things like smell-causing mold and bacteria. No matter what time of year it is, open the curtains and drapes throughout the house on a sunny day and let the UV rays in. Sunlight can be an effective odor killer for carpets, furniture, pet areas, pillows and cushions, and other household items that can smell. Baking soda is one of the most popular deodorizers around, because it’s effective and cheap. To absorb smells around the house, sprinkle some baking soda into a couple of small dishes or plates and distribute them around the house. The baking soda will absorb odors from the rooms and get rid of bad smells. To further deodorize household items, sprinkle baking soda over things like carpets, furniture, mattresses, and other possible odor sources. Leave the baking soda for 30 minutes, and then vacuum it up. Vinegar is also an effective deodorizer that you can use to absorb bad smells around the house. Fill a few small bowls with vinegar and place the bowls in smelly areas around the house, such as:  Musty basements Bathrooms Kitchens Bedrooms Charcoal is similarly a powerful odor absorber that can be used in many rooms and inside appliances to deodorize. Be sure to use pure charcoal and not something that contains lighter fluid. Place a few pieces of charcoal on plates and distribute them around the house. You can put them in:  Closets Refrigerator and freezer Living areas Certain houseplants are known to clean the air, and they may help to control odors in the house as well. Houseplants you can grow around the house for air-purification include:  Snake plants English ivy Lady palms Dracaena

Summary:
Open windows. Use fans to increase circulation and get fresh air flowing. Let the sun shine in. Use baking soda. Try vinegar instead to absorb odors. Deodorize with charcoal. Invest in air-purifying houseplants.
