Why Does My Room Smell Bad? Here’s Why and What You Can Do About it

Why Does My Room Smell Bad? Here’s Why and What You Can Do About it

​Styling your home is one thing, but keeping it odor-free is another. If your room spells S-W-E-A-T all over, this one’s for you. 

It’s no secret that “aroma” and “odor” are two very antagonizing scents. While the former refers to sweet or fragrant notes, the latter is often used to describe foul or offensive scents. The problem is, when your house crosses the line and it becomes odorous, you and your entire household become vulnerable to illnesses.

So instead of ignoring your nose whenever it asks 'why does my room smell bad?', here’s how you can keep your home sparkly and odor-free.

​But First, is Scent an Indicator of Indoor Air Quality?

Often times, scent becomes a basis of cleanliness not just for individuals, but for households as well. However, when it comes to your home, scent may not always be a great parameter for assuring air quality.

This is especially true if you are using deodorizers and air fresheners that mask the odor hiding underneath your sheets. Sure, these products can help, but only for a limited time. Once the effect wears off, the unpleasant smell comes back because the odor-causing microbes are still very much alive, kicking, breeding.

Worse, studies show that these deodorizing products may also emit volatile organic compounds (VOCs), which can consequently affect your health. Rather than increasing air quality, chemical-based products can actually add up to indoor air pollution.

Why Does My Room Smell Bad?

From faulty cleaning habits to improper aeration, the factors that contribute to a smelly room can go on and on. But for now, let’s focus on these major causes:

  • Mold growth: If your room already smells musty or you already see mold developing on your bathroom or kitchen walls, you have to act fast because you’re already exposed to a number of health risks. For a comprehensive mold prevention and treatment plan, read our previous post here.
  • Dust: Keeping your windows and your doors open is always a great practice unless your home is close to areas where dust and other air pollutants are rampant. If so, choose the most ideal time to let air in.
  • Stagnant air:  Proper ventilation is key to improving indoor air quality. Once the air becomes stagnant, it traps indoor pollutants from smoke and other gaseous components, leading to unnecessary odor. One quick solution: open your windows.
  • Unwashed clothes: Why does my room smell like sweat? If you haven’t done the laundry yet, you probably should. Given enough time, the sweat from your clothes can come in contact with germs and bacteria, which contribute to that sweaty odor that lingers in your room.
  • Pet litter and urine: Wondering where that foul smell is coming from? Better check your flooring and your carpets if you have a household pet.

​How to Properly Deodorize a Smelly Room: 2 Easy Steps

Identify the Source


Do you always feel heavy whenever you stay home? Do you often ask yourself, “Why does my room smell bad?” Well, you can spend hours lighting up scented candles, but the smell won’t go away if you don’t address the right issues in your home. Just like cutting wild grass, you should always aim for the roots, and that’s what you need to do when it comes to keeping odor at bay.

To put up an epic fight against any smelly room, carefully inspect areas in your home where mold and mildew tend to grow (i.e., bathroom, crawl spaces, and kitchen). Also, check for signs of dust buildup, along with the other potential causes of odor accumulation. Only by doing so can you create a plan that’s tailored to your home’s specific needs.

​Act on the Source


So you’ve figured out what causes those ghastly layers of stench. Great job! Now, it’s time for you to roll up your sleeves and work on deodorizing your home (the right way). Here’s how to get started:

  • Evaluate the level of mold development in your home so you can act accordingly. Natural and chemical-based cleaning agents can efficiently kill mold spores, but in cases of severe mold growth, replacing caulk, tiles, carpets, and flooring may be your best option.
  • ​After cleaning or replacing old building materials, consider using a dehumidifier in humid areas (i.e., kitchen, bathroom, and crawl spaces) so you can prevent future mold growth.
  • Clean household appliances (i.e., fridge, stove, air conditioner, and washing machine) that may be trapping odor-causing bacteria or fungus.
  • Make dusting and cleaning a habit, especially since air pollutants are always just around the corner. Use a wet cloth for hard surfaces and change your beddings and mattresses once a week. If you can, change your carpeted flooring to hardwood flooring so you can avoid dust buildup.
  • ​Aside from regularly cleaning your home, investing in an air purifier can also help you clear the air from odor-causing pollutants.
  • Let air circulate by opening your windows. Contrary to popular belief, outdoor air is healthier than stagnant indoor air. However, you may need to check the weather and the outdoor air quality if you are allergic to pollen.
  • Don’t keep your laundry piled up for weeks because sweat and bacteria aren’t a good combination. 
  • ​If you own a pet, always practice proper pet care so you won’t attract any foul odor. We all know the perks of having a pet, but hey, pet hygiene should always come first.
  • Lastly, use a natural home deodorizer such as lemons, baking soda, oranges, and coffee grounds.

Why does My Room Smell Bad? Changing Household Scent Involves a Lifestyle Change

There’s literally no way to continuously keep your home fresh and odor-free without forming a strict cleaning habit. The chores may never end, but the reward of having a healthy household is priceless. By staying faithful to your goal, you can enjoy a home that doesn’t just look like a home, but also smells and feels like a home.
