7 Natural DIY Methods to Deodorize Your Home
- Sprinkle Baking Soda Overnight
- Run an Air Purifier with a HEPA/Carbon Filter
- Grind Coffee Beans
- Set Out a Bowl of Rubbing Alcohol Gel
- Create a Spray Using Essential Oils
- Apply Vinegar Solution to Smelly Areas
- Use Charcoal Air Fresheners
1. Sprinkle Baking Soda Overnight
Quick Take
Baking soda is a staple in everyone’s kitchen for a reason—it absorbs and neutralizes odors rather than covering them up. It's especially effective at absorbing smells from carpets, upholstery, or refrigerators.
What You’ll Need
- Baking soda
- Vacuum cleaner
- Sifter or shaker container
Step-by-Step
- Sprinkle baking soda generously over smelly surfaces.
- Let it sit overnight (or at least a few hours).
- Vacuum thoroughly to remove all residue.
Why It Works
Baking soda is alkaline, which allows it to neutralize both acidic and basic odor compounds. It doesn’t mask smells. It eliminates them at the molecular level.
Pro Tip
Use a fine mesh strainer or an old spice jar to apply the baking soda evenly.
2. Run an Air Purifier with a HEPA/Carbon Filter
Quick Take
Using a HEPA air purifier with a carbon filter such as an Alen gives your air a serious refresh. No sprays or toxic chemicals are required. It’s an easy upgrade for whole-room odor control.
What You’ll Need
- Air purifier that has a filter with HEPA and activated carbon. Alen’s Advanced and Ultimate filters have both a HEPA layer and a carbon layer to capture gaseous contaminants, including odors. Alen’s Ultimate filters also contain a catalyst that adsorbs even more odor.
Step-by-Step
- Place your purifier in a location with good airflow.
- Run it continuously.
- Use multiple air purifiers for the most frequently used rooms in your home.
Why It Works
HEPA filtration captures 99.9% of particles as small as 0.1 micron, while activated carbon absorbs odor molecules contained in contaminants such as common household odors or Volatile Organic Compounds (VOCs). How does the carbon layer work? Carbon’s porous surface binds these gases and traps them, according to research.
Pro Tip
Change the filter on your air purifier regularly (for an Alen, it’s every 9–15 months depending on the filter) to maintain optimal performance.
3. Grind Coffee Beans
Quick Take
Coffee beans serve a purpose other than in your morning cup of java. You may be surprised to learn that coffee beans also neutralize stubborn smells. That’s right—they’re perfect for closets, shoe cabinets, or anywhere odors linger. Who knew!
What You’ll Need
- Freshly ground coffee beans or used grounds (dried)
- Small bowls or breathable pouches
Step-by-Step
- Fill small containers with dry coffee grounds.
- Place near odor sources such as trash bins or bathrooms
- Replace every 2–3 weeks.
Why It Works
Coffee grounds contain nitrogen, which helps neutralize sulfur smells and other VOCs. Their texture also naturally absorbs odors from the air.
Pro Tip
Apply used grounds. Just ensure they’re completely dried.
4. Set Out a Bowl of Rubbing Alcohol Gel
Quick Take
Rubbing alcohol is another one of those products that’s typically in your medicine cabinet. Did you know that when it evaporates, it pulls in odor particles? Yes! It's a fast-acting fix for musty spaces.
What You’ll Need
- Rubbing alcohol (70% or higher)
- Gel base (like aloe vera gel)
- Bowl or small container
Step-by-Step
- Mix rubbing alcohol with gel to slow evaporation.
- Pour into an open dish.
- Place in odor-prone rooms for 1–2 days.
Why It Works
Isopropyl alcohol vapor binds with odor molecules and helps dispense them as it evaporates. The gel elongates this process.
Pro Tip
Use in small spaces, such as entryways or laundry rooms. Ensure it’s out of reach of children and pets.
5. Create a Spray Using Essential Oils
Quick Take
Essential oils offer another natural way to freshen your indoor air. Lavender, lemon, and eucalyptus are wonderful scents for your home and work particularly well against lingering smells.
What You’ll Need
- Distilled water
- Witch hazel
- Essential oils of your choice
- Spray bottle
Step-by-Step
- Mix 1 cup water, 1 tbsp. witch hazel, and 10–20 drops of essential oil.
- Shake before each use.
- Spray into the air or onto fabrics.
Why It Works
Essential oils have antimicrobial and deodorizing properties. Lemon and tea tree oils, in particular, can help minimize odor-causing bacteria.
Pro Tip
You can start with a few drops and continue to add more to obtain your desired strength.
6. Apply Vinegar Solution to Smelly Areas
Quick Take
White vinegar’s high acidity helps break down and neutralize odors at their source. It’s especially effective in kitchens and bathrooms.
What You’ll Need
- White vinegar
- Spray bottle
- Water (optional to dilute)
Step-by-Step
- Fill a spray bottle with undiluted or partially diluted vinegar.
- Spray directly onto problem surfaces or into the air.
- Let dry completely. Don’t worry, the vinegar scent will fade.
Why It Works
According to research, vinegar’s acetic acid dissolves odor molecules and breaks down bacteria and mildew. It’s a proven disinfectant and deodorizer.
Pro Tip
Don’t use vinegar on stone surfaces such as granite or marble. Vinegar can dull or possibly stain a marble surface.
7. Use Charcoal Air Fresheners
Quick Take
Activated charcoal is one of the most powerful natural deodorizers. It traps and absorbs odor molecules in its thousands of micro-pores.
What You’ll Need
- Activated charcoal pouches or bags
- Hooks or drawers for placement
Step-by-Step
- Place charcoal pouches in areas that are prone to odors.
- Let it sit for 24–48 hours.
- Recharge in sunlight monthly to refresh.
Why It Works
Activated charcoal has a porous structure that acts like a sponge, trapping gases and odor molecules.
Pro Tip
Use in closets, cars, gym bags, and near litter boxes for constant odor control.
