Best HEPA Air Cleaner For Dog Dander and Allergies

How do you pick the best air purifier to help with pet allergies?

Do Air Purifiers Help Dogs With Allergies?

To understand this question, it’s important to understand how both pet allergies and air purifiers work. Contrary to popular belief, pet allergies aren’t caused by pet hair. Instead, they’re caused by your pet’s dander. This means that there is no truly “hypoallergenic” pet, as all pets shed some form of dander.

Dander and Allergies

Pet dander is made out of the flecks of skin that all animals with feathers or fur shed. These skin flecks can be so small they’re microscopic. A pet’s skin has proteins that, while harmless to most people, can trigger an allergic reaction in some people. You might also react to allergens in your pet’s saliva or urine.

It’s possible to be allergic to pets, or to have respiratory conditions like asthma worsened due to pet allergens. When this is the case, breathing in these allergens might worsen your respiratory symptoms and reduce the function of your lungs.

The amount of allergen necessary to cause reactions will vary depending on the severity of a person’s allergy. When a person has an allergic reaction, their immune system releases histamines into their body. This causes watery eyes, runny noses, shortness of breath, sinus congestion, and possible itchy rashes.

How Pet Dander Invades the Home

Pet allergens are small and lightweight, which allows them to remain airborne for a much longer period than dust mite or cockroach allergens. The uneven shape and microscopic size can make pet allergens cling to fabrics, bedding, and furniture.

Because pet dander is so easy to spread, it can often be found in areas that don’t have any pets.

Using HEPA Filters to Remove Pet Dander

It should be noted that the primary way to protect yourself against pet allergies is to avoid having a pet in the home. Allergens might be part of the environment for several months after an animal has left, since the dander exists in dust.

If you don’t have the option to go without pets, you should make sure your pet stays out of the bedrooms of all family members with allergies or asthma. It’s also helpful to keep your pet from climbing on your furniture and keep them away from your carpeting as much as possible.

One effective way to remove dander that’s settled on the ground is through routine vacuuming. However, a vacuum will only reduce the pet dander that’s settled on your carpets and floors. Airborne particles will require a HEPA filter.

Purifying the Air

You can’t vacuum the air. To reduce the allergens in the air, the air itself needs to be continuously cleaned. This means you should invest in an air purifier that has a high air flow rate. Because pet dander is made up of mid-size and large-size particles, you don’t need to focus as much on filtering ultrafine particles.

To receive a HEPA certification, a filter must be able to capture at least 99.7 percent of particles in the air. When deciding on an air purifier, consider how much space needs purifying, along with the allergens you’re trying to filter out. Most filters will take care of pet dander, but smaller allergens might need more high-tech filters.

Air purifiers with HEPA filters are better than ionizing air purifiers. Ionizing air purifiers emit ozone, which is a harmful substance that can coat your surfaces if the purifier is used too often. People with pet allergies will want to keep their air purifier running most of the time.

Your bedroom should have an air purifier that takes care of your environment while you sleep. If you work in the home, you might want to bring the air purifier with you into your living spaces. Keep your frequently-occupied spaces as free of pets as possible.
