Others contain purifying liquids or solids to deodorize and soak up bad smells where they lurk. It is up to you whether you want to be whisked away to a tropical paradise every time you inhale or not smell a thing but clean.

What to Consider When Buying the Best Air Freshener

Air fresheners really come down to personal preference. Do you like strong scents or clean, unfragranced air? From this starting point, you can decide whether a spray, gel, sachet, or diffuser is right for you. Other important considerations are the size of your room and how long you’d like the product to last. Finally, think carefully about your health and any allergies or sensitivities you may have.

Type and Intended Use

There are many different types of air fresheners on the market. From sprays and sachets to plug-ins and gels, it can be hard to figure out which formula and dispenser style is best for you. Let’s break air fresheners down into their main categories:

  • Spray: Air freshener sprays are versatile and incredibly easy to use. Just spray them into the air or onto a smelly surface and let the ingredients do their work. Spray fragrances don’t linger in the air for long, which can be an upside or a downside depending on your needs and preferences. Sadly, most sprays come in single-use plastic bottles, which have a negative impact on the environment.
  • Gels: Odor-busting ingredients like essential oils can be suspended in gel. Gels evaporate slowly, ridding the air of foulness in the process. Because gels’ fragrances are usually quite mild, they are best for freshening air in smaller spaces, like bedrooms and bathrooms.
  • Sachet: Scented sachets have traditionally been filled with dried herbs or lavender. However, the best odor-eliminating ingredient for sachets is one that isn’t scented at all. Activated charcoal sachets are eco-friendly, remove unwanted odors, and are the best bets for folks with allergies. These sachets are available in a wide range of sizes, including extra-large to purify an entire room and very small ones suitable for deodorizing a closet.
  • Diffuser: Available as plug-in, electronic, or stand-alone units, diffusers all have the same basic function: to pump micro-bursts of fragrance, either natural or synthetic, into the air. Essential oil diffusers are really a product category of their own. They differ from plug-in and electronic models in that they mix fragrance with water, humidifying and purifying air at the same time.

Strength and Longevity

How big is your room? How bad is the smell? Answers to these questions will help determine the best air freshener for your situation. Sprays and gels are usually best for smaller, enclosed areas. Sprays are also effective if you need to target a soft surface, like a sofa or rug to eliminate pet odors, for example. Sprays and gels should be strong enough to kill the bad smell, without being overpowering. Once they serve their purpose, their own scent should evaporate and leave clean, chemical-free air behind.

Diffusers, on the other hand, are intended for larger spaces like bedrooms, living rooms, and offices. Instead of scrubbing the air of bad smells, diffusers inject nice fragrances into your indoor environment, which linger for some hours. Plug-in and electronic diffusers are timed to release micro-bursts of fragrance from a cartridge or aerosol can. These units typically last 60 days before the cartridge (or can) needs replacing. Essential oil diffusers require just a few drops of essential oil, plus water refills, to keep air fresh day after day.

Scent and Ingredients

Air fresheners have reputations for being heavily and artificially scented, but that’s not the full story. It’s true that some plug-in diffusers and sprays contain synthetic fragrances and known toxins like phthalates. However, many air-freshener brands are appealing to health- and eco-conscious customers by upgrading the quality of their ingredients. Look for labels that list the types of chemicals not included, like dyes and alcohol, as well as those that tout ingredients like all-natural or organic essential oils. Products that contain ingredients deemed safer for human health and the environment receive Safer Choice certification from the Environmental Protection Agency (EPA).

Popular home fragrances run the gamut from florals and botanicals to vanilla and spice. Citrus is also a classic, refreshing choice, especially for kitchens and bathrooms. Of course, if you have scent sensitivities or simply prefer clean, unfragranced air, charcoal sachets work, too.
