As much as we love our furry friends, there’s no denying that pets can pong from time to time. Whether you’re a cat, dog, hamster, or even a fish household, having a pet in your home will inevitably contribute some unpleasant smells over time.  

Although this is a small price to pay for the love and companionship of having a pet in the family, I’m sure we would all love to eradicate these unpleasant odors. Especially when you consider we often become nose blind to the smells in our home, so it may be even worse than you think! 

With the pet industry booming in recent years, there are many innovations you can buy to help care for your pet. But when it comes to unwanted odors, one of the most effective solutions is to invest in a quality air purifier. 

In order to tackle 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. As each purifier on our list also utilizes HEPA filters, they can easily capture and remove these particles and odors from the air. 

When choosing an air purifier, bear in mind that different machines are best suited to certain size spaces. So whether you’re looking for a large-room purifier like the Conway Airmega 400, or a purifier suited to a small space like the Winix HR900, we’ve included a range to suit everyone’s needs.

We analyzed Consumer Reports and genuine customer reviews to ensure each purifier has been endorsed by real users and you can rest assured they will leave your home feeling fresh and free from pet odor.

FAQs about Air Purifiers for Pet Odor.

Can pet odors cause illness?

Pets, especially young ones, have “accidents” from time to time, or perhaps your pets like to “mark their territory”. Either way, if left unattended, pet odors can not only be unpleasant, but they are potentially harmful to your health.

When bacteria in the air mixes with the pet “accidents”, particularly urine, chemical gases are produced. Inhaling these gases for any length of time can lead to:

  • Asthma
  • Lung infections
  • Nose and throat burning sensations
  • Eye or skin irritation

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 certain molecules attach themselves to an external surface instead of being soaked up (absorption). An activated carbon filter that has 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 over time things begin to smell.

A top-quality air purifier goes a long way to combat not only the dander, but will kill any bacteria in the air, and greatly reduce if not eliminate the odors associated with the four-footed members of your family.

Which Air Purifier is Best for You?

If you’re suffering from allergies, notice the presence of pet odors in your home, or if your pet happens to be allergic to dust, pollen, or other animal’s dander, then an air purifier designed specifically to help eliminate these problems should not only make you feel better, but also your pet’s health may improve, and your home will smell fresher and cleaner.

Think about:

How large is your room?

Look for “coverage area” or “room size suitability”. Choose an air purifier that corresponds to your room’s sq. ft.

What size is the purifier?

Select a purifier of a size that will fit in your room.

How noisy is the purifier?

Each air purifier will state the noise levels in decibels (dB). The lower the number, the quieter the unit will be.

How much can you afford to spend on a purifier?

We don’t recommend buying the most expensive one available. A cheaper model may be just as effective for your purposes.

Pick an air purifier that gets rid of odors, cleans the air efficiently, is of a size you can fit in your room, is quiet enough to be located in a bedroom, and is the most cost-effective for you.
