A Brief Background on Odors
Before we jump into the list of the top air purifier odor removers, we wanted to go over two things:
- The real cause odors
- How smells travel through the air
Knowing this background information will help you better understand—and appreciate—how air purifiers work to eliminate odors in your home.
What Causes Odors?
Odors don’t just come out of thin air.
In fact, even though smells are invisible molecules, they always stem from a particular source, such as mold, pets, cooking, garbage, chemicals, etc.
An odor is caused when the chemical compounds within a substance become volatilized (released as a vapor). And that smell (or scent) can be perceived as pleasant (fragrant) or unpleasant (repulsive).
Some substances are very volatile and produce a large number of odor molecules. That’s what makes things like rotten food or chemical cleaning agents smell so strongly.
Other substances are not very volatile and barely have a scent at all, like metal and steel.
The truth is that some odors occur naturally during evaporation while others only happen during decomposition or chemical changes.
A fun fact is that the human nose can detect about one trillion odors which makes your sense of smell more powerful than people think.
Most Common Types of Indoor Odors
As for the most common types of indoor odors, they stem from:
- Kitchen (cooking food, spices, and associated smoke)
- Garbage (rotting food)
- Chemical Cleaners
- Pets (Dog skin and Cat litter boxes)
- Paints and Varnishes
- Construction Materials (carpeting, wood, and drywall)
- Mold and Mildew
- Damp Rooms (basements and bathrooms)
Fortunately, an air purifier can eliminate most of the odors that come from those places so that the air around you smells fresh.
We’ll get to the exact features for what to look for in the best air purifier for odors in the next section, but first, we wanted to share with you how smells travel through the air.
How Do Smells Travel Through the Air?
Unlike solid substances, like dust and pollen, that clump together and attach to surfaces, smells are free-floating gaseous molecules.
Therefore, odors don’t collect in one spot and remain there, but rather spread out far and wide through a process called “diffusion”.
Diffusion is a process where a high concentration of particles moves to an area of lower concentration. This happens naturally with odors because gaseous particles move randomly from place to place without any controlled path.
Diffusion is the reason why even small sources of odors, like a dog bed or a burnt piece of toast, can spread throughout an entire room or house. The odor molecules can’t stop invading the fresher air.
What to Look for in an Air Purifier for Odors
Air purifiers are amazing machines.
However, not all air purifiers can remove odors.
In fact, if an air purifier doesn’t contain at least one particular type of filter, then it won’t reduce any odors at all.
Also, some air purifiers claim to be odor eliminators, but the technology they use only masks the smell as opposed to getting rid of the gaseous molecules.
So, to make sure you get the best air purifier for odor elimination without wasting your money, you’ll want to look for these features in the product that you buy:
Activated Carbon Filter
An Activated Carbon filter is the only type of filtering material that can actually eliminate odor molecules.
It’s a highly porous substance that traps the organic chemicals that create smells.
As air passes through the Activated Carbon filter, odor particles are adsorbed to the material, while fresh air passes through the other side.
On a scientific level, Activated Carbon is a specially processed form of carbon that contains millions of microscopic pores. This results in a greater surface area that’s designed to trap gaseous molecules of all types.
If removing odors is your top concern, then make sure that the air purifier you choose has a thick layer of this material in its filter. (The top three air purifiers we recommend below meet this criteria.)
The advantage of Activated Carbon filters is that they can remove smells from all sorts of sources, which is why you’ll find them in the best air purifier for pet odors, mold smells, cooking, garbage, paint, chemical vapors, etc.
While many of the top air purifiers today come with a HEPA filter, it’s important for you to know that this particular filter cannot remove odors.
Instead, HEPA filters are designed to capture solid particles, like dust, pollen, pet dander, visible smoke, and bacteria.
Gaseous vapors pass right through the HEPA material.
However, some solid particles do emit odors, like mold spores and tobacco smoke, which is why having a high-quality HEPA filter on your air purifier is still essential.
The HEPA filter will trap solid particles inside a dense mesh and help reduce the spread of smells around your home.
An ionizer is another form of technology you’ll see advertised when looking for an air purifier for odors.
In fact, some products are labeled specifically as an “air purifier odor remover” that only contains this functionality.
You’ll also find other air purifiers that include both the Activated Carbon filter and HEPA filter in addition to an ionizer. In these cases, the ionizer is a supplemental feature that works to boost the efficiency of the machine.
But what is an ionizer and how does it help reduce odors?
Ionizers emit negatively charged ions into the air that latch onto particles to weigh them down. This causes pollutants to fall onto the floor or stick to surrounding surfaces.
Vapor molecules that have been ionized cannot scatter throughout the air, and therefore, won’t radiate their smell. However, those particles still technically remain in the room, so if you turn the ionizer off, the smells may come back.
Something else you should know about ionizers is that some versions do create ozone as a by-product, which also has air neutralizing capabilities.
But, ozone can be harmful to your health if you’re exposed to high concentrations of it.
Fortunately, most ionizers emit an ozone level of less than 0-0.05 ppm which is considered safe for humans by the U.S. Environmental Protection Agency (EPA).
As you can see, an ionizer can boost the air cleaning power of your air purifier, but it’s not an essential feature. It’s optional. The only true filter you need to eliminate odors with an air purifier is an Activated Carbon filter that we covered first.

Enjoy Air That’s Free of Odors
We hope you found this guide on how to choose the best air purifier for odors useful.
As you learned, the best air purifier for smells is one that includes an Activated Carbon filter.
Activated Carbon is the only material that can truly trap and remove smells from the air around you.
So, regardless if you’re looking for an air purifier for dog smell (or other pet odors), a cooking odor air purifier, a paint smell remover, or a machine to get rid of musty smells in a basement, an Activated Carbon filter is the best filter to handle those gaseous pollutants.
But, if you want to save a bit of money on your air purifier purchase, the second best air purifier for odor elimination is one that uses an ionizer.
Ionizers are a special type of technology that neutralizes odors without using a physical filter material. However, they’re not as efficient as an air purifier with an Activated Carbon filter since ionizers don’t actually remove the odor particles from the room.
Ionizers are still a good cheap option for removing smells if you can’t afford a higher-priced filter-based air purifier.
Finally, no matter which air purifier you choose on this page, you can rest assured that the odors inside your home will be greatly reduced or go away entirely—leaving your space smelling fresh and clean.
