As much as we love our furry friends, there’s no denying that pets can stink occasionally. Whether you’re a cat, dog, hamster, or fish household, having a pet in your home will inevitably produce unpleasant smells.
If you don’t think your pet smells, then you might be nose blind to the smells in your home, so be sure to ask guests what they think about the odor, as it could be worse than you think.
The best way to remove odors from your home is by using an adsorption filter like activated charcoal. Many air purifiers are marketed to remove pet odors, but many are not fit for the purpose.
Thankfully, we can share, based on our internal experiments and testing, that the following air purifiers are our top pick for pet odor:
The Top 3 Air Purifiers For Pet Odor in 2023




Why trust us?

At HouseFresh, we have been testing air purifiers for over 10 years, and we actually test them and then use them in our homes to understand the long-term experience. We always buy the units with our own money, so we can say what we think, and sometimes they are awesome but stink. We test all our air purifiers in the same sized room so you can calculate how it could work for your space. It also allows us to evaluate all types of air purifiers for the one test they are purchased for – cleaning a room of particulates. Using our internal data, we can recommend specific use cases like “pet smells.”
If you care less about odors but still have a pet then be sure to look at what we think is the best air purifiers for homes with pets as of 2023.
We share all our data using Flourish and hope to support as many consumers as possible in finding the right air purifier for their needs and budget.
Read on for the detail behind our recommendations:
1. Blueair Blue Pure 211+ – Best Overall for Pet Odors
The Blueair 211+ uses a filter system called “HEPA Silent,” which combines HEPA and activated charcoal filter with an electrostatic charge that performs better than pure mechanical filter systems.

The addition of activated charcoal is key for removing odors from the air, which is key for those of us who live with pets.

When we tested the non-smart version of this air purifier called the 211/221, we found that it performed well in our room cleaning test and removed all the pollutants in 18 minutes, our second-best score only being beaten by far larger Smart air Blast. The auto mode is a welcome addition with some energy efficiency improvements over the older model, with peak wattage max out at 38 watts vs 55.5 watts we recorded with the 211, and has a slightly better CADR score.

This unit is a little larger than the other suggestions, but it does mean that it can perform at a higher level with a CADR of 265 CFM, which matched with our performance test that showed the Core 400S removed all pollutants in 33 minutes which is close to $1000 IQAir Healthpro Plus.

Unlike the IQAir model, this unit comes with a ton of technology under the hood, with auto-mode and app support from day one. You can see how clean or dirty your air is, and the unit can automatically switch the fans on to remove pollutants and switch off when it’s not needed.

What You Need to Know About Using an Air Purifier to Get Rid of Pet Odors
To tackle pet odors, or any volatile organic compound (VOC), you will need a purifier with an activated carbon filter. This filter, made up of a sponge-like bed of charcoal, works by absorbing VOCs from the air as they pass through the purifier.
As well as odors, we know pet dander and hair can be a nuisance when cleaning your home and trigger allergies, amongst many other unpleasant side effects. An air purifier can certainly help with this issue too. Each purifier on our list also utilizes HEPA filters, so they can easily capture and remove these particles and odors from the air.
🤔 Will an air purifier help with dog smell?
An air purifier can do a great deal to remove odors, including those from dogs if it has an adsorption filter, the most popular being activated charcoal. Without this filter, HEPA alone cannot remove dog smells or any other odors in the home. Activated charcoal is carbon that has been treated with high heat and works by trapping odors and is effective for odors and has been proven in multiple peer-review studies.
🤔 Can pet odors cause illness?
Pets, especially young ones, sometimes have ” accidents, ” or perhaps your pets like to “mark their territory” with urine. Either way, pet odors can be unpleasant and potentially harmful to your health if left unattended, as the ammonia can be released from urine stains over time.
The release of ammonia can cause several health problems, such as:
- Coughing and asthma symptoms
- Lung infections
- Nose and throat burning sensations
- Eye or skin irritation
Source: New York Health Department
The best way to remove ammonia from the air is to use an adsorbent filter like activated charcoal. This is the primary material in most air purifiers aimed at removing odors from the air but is not always used, so be aware.
🤔 What do activated carbon filters do to pet odors?
Activated carbon or activated charcoal filters work by trapping those odors through a process known as adsorption, which occurs when specific molecules attach themselves to an external surface instead of being soaked up (absorption). An activated carbon filter with more porous carbon will increase the area of surface space that the odor molecules can attach to when the air is drawn through the filter.
🤔 What are the advantages of owning an air purifier to combat pet odor?
Pets, especially dogs or cats, are continually shedding particles which can lead to health issues. However, it’s not the hair that causes the problem, but the dander from dead skin cells they shed. Your pet can also bring all sorts of other unpleasant items into the house from outside, and things begin to smell over time.
A top-quality air purifier goes a long way to combat not only the dander but will remove any bacteria in the air and significantly reduce, if not eliminate, the odors associated with the four-footed members of your family.
How to Find the Best Air Purifier for Pet Odor
Pets are cute and all, but there’s no denying that sometimes after you’ve had pets indoors with you for a while, the odor of the home changes.
It might be harder for you to catch this smell, especially since you might have been around it for the longest time, so your body system might already be familiar with it.
However, the best way to find out is to ask guests visiting you if they get any unpleasant smells from your home.
Now, we understand that your pet is your best friend, and you probably want it around all the time, and that’s okay. So, the challenge is; How do you keep your pets around while maintaining a fresh and pleasant smell around your home?
Our solution is straightforward- Get an air purifier for pet odors.
What Are Air Purifiers and How Can They Help?
Pollutants in a home can contribute to a poor environment and negatively affect the human body. Inhaling fine pollutant particles, especially those with a small diameter, can cause numerous lung and heart diseases.
Air purifiers are designed to filter the air in the space where they are found. They improve the air quality in a room by removing pollutant sources, especially the tinier particles, and replacing the room with cleaner, healthier air.
When it comes to getting rid of odors, it can be more challenging for air purifiers. Odors are generally stronger, and only air purifiers that use activated charcoal for the purification process stand a chance of eradicating the odor and restoring the smell in the room to normalcy.
The Function of an Activated Charcoal Air Purifier
There are several types of air purifiers. Purifiers are classified according to the type of technology they employ for the purification process.
The types of air purifiers include;
- Mechanical filters
- Activated carbon filters
- Ozone generators
- Ultraviolet Germicidal Irradiation
- Photocatalytic Oxidation
Of these purifiers, activated carbon works more effectively to eliminate odors. It has special properties allow it to eradicate Volatile Organic Compounds (VOCs), Odors, and other gaseous pollutants. It has micro and macro pores that pull molecules into itself, trapping them into the activated carbon and absorbing them, thereby neutralizing the odors.
HEPA filters also come highly recommended. HEPA filters are made with fine mesh and are certified to collect up to 99.97% of particles of a certain size (0.3 micrometers in diameter).
Not all filters have this HEPA technology, especially cheaper air filters. If you want to get rid of odors in your home, you should go for air filters with activated carbon and HEPA-certified. The more money you spend on an air filter, the better the performance you should expect from it.
Our Top 3 Air Purifiers for Pet Odors
When it comes to pet odor, these three purifiers top our list;
All three filters are HEPA certified. However, Blueair is leading our options because it uses HEPA silent technology. This is an electrostatic filtration that has both HEPA and activated charcoal. It is very effective in eliminating odors. Suppose you are not very comfortable with the use of electrostatic technology. In that case, you go for the Levoit Core 300 or the Alen BreatheSmart 75i, which are also very effective air purifiers for pet odors.
What to Consider Before Buying an Air Purifier
- Room size
- Noise level of the purifier
- Certifications. Ensure that the purifier has the necessary certifications.
- Cost of replacement filters. Filters should be replaced regularly, so ensure the replacement cost is within your budget.
That said, a high-quality filter will do an excellent job and eliminate the strongest odors.
