What Causes Unpleasant Household Odors

Entering a room that has an unpleasant smell is a nightmare, especially if you can’t figure out where the smell is coming from. Fortunately, with the addition of an air purifier that specializes in odor removal, you won’t have to worry that you might enter a room and find that it smells weird. Generally, there are some common causes for unpleasant household smells, and if you want to find out what these causes are, you should check out the following lines.

  • Smoke

  • If you are a smoker or someone else who lives in your home is, the smoke from the cigarettes will embed in the walls and carpets, and it will linger in the air, making the house smell awful. Worst of all, there are thousands of cancerogenic chemicals that are released in the air because of cigarette smoke, chemicals that can do a great deal of damage to your health. Fortunately, with the addition of an air purifier for odor removal, you won’t have to worry about the smell or the harmful effect of the chemicals that are released because they will be removed from the air effectively.

  • Pets

  • No matter how clean you think your pet is, it’s surely one of the causes of the unpleasant smell indoors. After all, you’re not there every second of the day to clean after the animal when it does its business, and in case it finds the rug to be the ideal place to do them, the smell will linger even after you clean it. Also, animals, especially dogs, tend to smell bad after they get wet or dirty from playing outside, a smell that they bring inside if they sleep in the house.

  • Sink Pipes

  • When the sink is obstructed, a sour smell will be released in the air from the drain. Although a purifier will remove the unpleasant smell effectively, you still have to dissolve the clog to get rid of this issue. Therefore, in case there are unpleasant smells in rooms such as the kitchen or the bathroom, rooms where you have sinks, make sure that you check the pipes.

  • Cooking

  • A room where unpleasant smells are inevitable if you don’t have a great performing unit of this kind that specializes in odor removal is the kitchen. The reason why these smells are almost permanent is obvious, the foods that you prepare causing them.
