It’s no secret that cats make pretty awesome pets. Their laid-back lifestyle makes them loveable while their independent nature makes them easy to care for. Yet for many people, the allergens they produce are enough to turn them from feline friends to feline foes.

As many as 3 in 10 people have pet-related allergies, so if a new partner has a cat, you’ve adopted a ‘hypoallergenic’ cat (sorry, there’s no such thing), or even if the friendly neighborhood stray has wandered into your home, that may explain why you’ve experienced an adverse reaction – especially as you’re twice as likely to be allergic to cats than dogs.

While allergic reactions vary between people, if you’ve suffered from any of the following symptoms after being around a cat, the chances are you have an allergy:

  • Sneezing or a runny or stuffy nose
  • Facial pain (from nasal congestion)
  • Coughing, chest tightness, shortness of breath, and wheezing
  • Watery, red, or itchy eyes
  • Skin rash or hives

The root cause of cat allergies comes from the proteins (i.e. dead skin, hair, and saliva) that they shed. Although these particles are often so small they cannot be seen by the naked eye, they can in fact be captured by air purifiers with a HEPA filter, which are capable of trapping particles as small as 0.3 microns. As cat allergens range between 2.5 and 10 microns in size they will readily eliminate them from your domestic environment.

We’ve included a range of air purifiers to suit different budgets among our top selections, however, it’s important to remember that each purifier will work differently in a given space. Checking the CADR score will give a good indication of how powerful the air purifier is and how well it will work in larger or smaller spaces.

We also made sure to check Consumer Reports and analyze product reviews through Fakespot, to ensure genuine users have certified that these purifiers are up to the task at hand.

FAQs About Air Purifiers for Cat Allergies

How do you know if you have a cat allergy?

Signs of a cat allergy are simple enough to spot. Shortly after you’ve encountered a cat, having come into contact with its dander, urine, or saliva, you’ll start noticing symptoms. Some people develop a rash or hives around the upper chest, face, and neck areas.

Commonly, people suffering from this kind of allergy can also experience inflammation of the eyes and a stuffy nose. This is because the allergen from the cat can cause the membranes around your eyes and nose to swell, causing the typical symptoms that present in allergies.

What issues can cat allergies cause?

There are a few issues that cat allergies can bring to the surface. For instance, if the allergens reach your lungs, they will trigger an antibody reaction and lead to manifestation of symptoms that could include wheezing, difficulty breathing, and coughing.

In chronic asthma sufferers, it is even easier to trigger symptoms, with the potential to actually instigate an acute asthma attack.

If you don’t treat your allergies, it is normal for them to induce fatigue as well. You may even develop an ongoing cough because of the postnasal dripping that originates from untreated allergies.

Can you treat cat allergies another way?

Preventing allergies isn’t possible, but there are plenty of ways you can treat them.

Besides an air purifier, you can use antihistamines to suppress cat allergies. These are available over-the-counter, but doctors can also prescribe them. Common antihistamines include Benadryl, Claritin, and Allegra.

Doctors may also recommend other over-the-counter allergy drugs like decongestants. This includes medications such as Sudafed or any other allergy drug which contains the ingredient pseudoephedrine, like Zyrtec-D or Claritin-D.

There are also nasal steroid sprays used for asthma and allergy symptoms. Sprays like Flonase are available over-the-counter.

Which Air Purifier is Best for You?

Whether you are already on medication or you’re seeking an alternative method to combat cat allergies, a quality air purifier with the right technology can make life more comfortable for you. Air purifiers specifically targeting these allergies are effective at clearing the air of smaller particles, making sure to capture every allergen so that you can breathe better day and night.

The right purifier can ensure that you and your furry friend will live in harmony as much as possible. If your symptoms are typically mild, a purifier may even make sure you don’t have to use any medication, whether prescribed or over-the-counter, while you’re in your own house.

Therefore, it’s important to address the purifying technology and overall quality of each purifier before you settle for one. We hope our reviews will help you narrow down your options so you can get back to enjoying your cat and your home.
