What to Consider When Buying a Basement Odor Eliminator

When shopping for the best basement odor eliminator, start by thinking about the size of your space—you’ll want a product that’s powerful enough for the size of the room, but not so powerful that the solution becomes overwhelming to your senses.

Next, consider who lives in your home; if you have children or pets, make sure you choose something that’s safe for kids in case they get a little curious. Finally, decide if you want a product that you control when you need it (like a room spray) or if you want something that works 24/7 on its own (like charcoal bags or an air purifier).

How We Chose the Best Basement Odor Eliminators

As shopping experts, our only job is to help you find a winning product. We start with the research and reporting basics—what products are made of, what they look like and how much they cost—to ensure that we’re only recommending the buys that are worth your time and money. Then, we research the features that speak to the product’s quality, taking advice from industry insiders and subject matter experts on what makes a product a smart value (or worthy of a splurge). Finally, we do the work of combing through user reviews to see how real people interact with the product, and if it stands up to the test.


What causes a musty odor in a basement?

A musty basement odor is most often caused by mold or mildew, and these fungi are stinky. If this is the case, you’ll want to follow this guide to preventing mold in basements and know what to do when your basement floods. These suggestions on how to get moisture out of the basement should also help.

Of course, be sure to review these tips for fixing a leaky basement so you don’t run into this problem again. If you’re thinking about finishing your basement (these basement remodel ideas can inspire any homeowner!), be sure to remedy any outstanding water and mold problems first.

Do odor eliminators kill bacteria?

It depends on the odor eliminator. For instance, products like Febreze Fabric Antimicrobial Spray and the HoMedics TotalClean Tower Air Purifier claim they kill 99% of bacteria, which helps get to the root of the problem. However, other odor eliminators (like scented room sprays, candles, charcoal bags and gels) simply trap odors or mask smells with another fragrance, rather than addressing the underlying bacteria.
