Cats bring us excitement and never fail to amaze us. Unfortunately, they can also release allergens, dust, and pollen into the air. This is why some cat owners experience red eyes and runny noses as a result of pet-related respiratory problems.

Taking the correct medication and minimizing triggers will help you prevent negative sensations. However, introducing an air purifier to the arrangement can help alleviate your suffering even more.

Air purifiers clean allergens and make your house more comfortable, but not all models are created equal. As a result, in this post, we will recommend the best air purifier for cat allergies to keep your home clean and healthy.

Causes and Symptoms of Cat Allergies

Actually, regardless of how vulnerable you are, you cannot be allergic to cats. Neither your cat nor its fur induces sneezing or red eyes. Instead, the protein found in cats’ saliva and sweat glands is what causes allergic reactions in humans.

So, what does it mean to have cat allergies? Such allergies arise when your immune mechanism attempts to safeguard your body against compounds that are not necessarily toxic to people but are misidentified as allergens.

The said protein itself is actually a molecule that is not harmful to the human body. Unfortunately, cat-allergic people’s immune systems are triggered once they come into direct touch with the cat’s fur.

The symptoms of cat allergies are identical to those of the other frequently diagnosed allergies: red eyes, runny nose, and frequent sneezing. If you identify yourself with any of these symptoms, you may be allergic to felines.

Even so, even if you have such symptoms, it doesn’t necessarily entail that you are sensitive to cat allergens. In fact, numerous allergies are to blame for such reactions. As a result, you should first ensure that it is not the annual flu or an allergy to another allergen.

Do Air Purifiers Really Help with Cat Allergies?

The air in our houses is made up of both liquid and solid particles. Air purifiers are intended to purify the air in an area by capturing allergens and reintroducing filtered, fresh air.

Pet dander is made up of more than just fur; it also comprises animal epidermis and saliva. Because these bits are very small and light, they can linger in the environment for a long period. Using an air purifier, you can remove those particles that cause allergic reactions caused by cats.

Depending on their specs and the type of filter installed, various air purifiers will provide varying degrees of benefit. HEPA filters, for example, may potentially eliminate the majority of dust, pollen, and other airborne particles larger than 0.3 microns.

Are Air Purifiers Safe for Cats?

Air purifiers come in a variety of sizes and styles, ranging from small desktop devices to big free-standing ones. Fortunately, most air purifiers on the market today have undergone extensive safety tests and are suitable for use in a house with animals.

In terms of tangible hazards, your cat could become entangled in the electric cable of the air purifier. Furthermore, large air purifiers are at risk of toppling and injuring your cat.

When selecting an air purifier for cat allergies, keep your cat in mind and choose a secure spot for it to ensure the safety of every member of your family. Place the air purifier somewhere it won’t be accessible or tipped over by your cat.

Furthermore, some cats may perceive the sound of the air purifier as annoying or unpleasant. Check to see how noisy their air purifier is while it is running. Remember that dB is not linear but exponential, so 50dB is many times louder than 30dB, for instance.

Always choose a device that will not harm your favorite cat. In most circumstances, ion generators and UV filtration are not suitable for some cats. It is usually always preferable to use HEPA and medical-grade air purifiers.

What to Look for in an Air Purifier for Cat Allergies

Here are some things to keep in mind when choosing an air purifier for cat allergies.


The first step is to look for a filtration that can eliminate particles as small as 0.03 microns. You may also determine the effectiveness of an air purifier by checking for an AAFA or ASL certification.

The kind of filter used might also reveal a lot about how efficient an air purifier is. Typically, the filter will include a number that should tell you more about how effectively it performs.

A higher value on these rating grades indicates a filter that can remove tiny particles from the environment. Because they can take out microparticles like pollen, mold spores, animal hair, and textile fibers, HEPA filters are suitable for most residential settings.


Air purifiers have different coverage capacities, which indicate how big a space they can purify. So, before you invest money in air purifying equipment, assess the size of your room to determine how large your air purifier should be.

The machine’s coverage is listed in most product descriptions and company notes. Nonetheless, the air purifiers are designed for normal ceiling heights. Thus, if your ceilings are high, the unit may become less efficient.


Some of the elite air purifying units are insanely expensive, but the majority of the higher-end versions have superior filtration and air quality management. That doesn’t mean you won’t find an effective and inexpensive solution.

Just make sure to pay close attention to the product details of the air purifier to ensure that it meets your requirements. Allergic people who are particularly sensitive to cat hair should use a high-powered purifier with a medical-grade filtration system.

Other features

Some elements are more of nice additions than just basic necessities. In general, more expensive purifiers include more capabilities, such as sensor warning lights, customizable lighting, and adjustable timers.

Other factors to consider include the air purifier’s noise and ability to humidify surrounding air. This may be useful throughout the winter or for those with asthma or sensitivities who have inflamed airways or nasal passages.
