Pet Dander in Your Air Ducts? 7 Tips for Cleaner Air

It’s no secret that Americans love their pets. But pet dander allergies cause congestion, sneezing, itchy or watery eyes, shortness of breath, and hives. If dander gets in your air ducts, it can spread around the home and exacerbate residents’ allergy symptoms. This guide explains what to do about pet dander in air ducts so you can enjoy an allergy-free home.

1. Change Your HVAC Filters

Your HVAC filters trap particles, dust, and pet dander to keep the air clean. But if you don’t change your filters often enough, those particles will find their way into your home and can affect your allergies. Disposable air filters last between three and 12 months, depending on the filter type and thickness. An HVAC technician can advise if you’re unsure how often to change your air filter.

2. Clean Your Air Ducts

There’s no set interval at which you should clean your air ducts. The National Air Duct Cleaning Association (NADCA) and the U.S. Environmental Protection Agency (EPA) recommend air duct cleaning as needed rather than every few years. But if you have pets, it could be beneficial to clean them regularly to keep dander levels down.

3. Use a Humidifier

Dry air can exacerbate allergy symptoms and increase your risk of respiratory illness. The EPA recommends keeping the humidity level in your home between 30% and 50% for the best air quality. If your home’s humidity is less than this, installing a humidifier can help. A whole-house humidifier costs $390 to $770 to install, with an average price of $580.

4. Use an Air Purifier

Air purifiers sanitize the air in a home to decrease allergens like pet dander. Installing a whole-house air purifier costs $420 to $4,960, or $2,610 on average. This type of purifier can reduce pet dander in the air vents throughout the home. Alternatively, a portable air purifier can be used in a single room, costing as little as $60.

5. Keep Your Home Clean

Regular cleaning can help keep pet dander from entering your air ducts and circulating around your home. Vacuum and mop floors and wash bedding often—especially in areas your pets frequent, like the living room or bedroom. If you struggle to keep up with cleaning your home, see whether professional house cleaning costs will fit in your budget.

6. Keep Your Pets Clean

In addition to keeping your home clean, keeping your pets clean can reduce the amount of dander in your home (and, therefore, your air ducts). If you have a dog, wash them once a week and brush them daily to decrease dander accumulation. Cats are usually more challenging to bathe but can still be brushed regularly to prevent them from shedding as much fur and dander.

7. Designate Pet-Free Areas

Although your pet is a cherished family member, that doesn’t mean they should have free rein in the house. Use doors and pet gates to create pet-free areas to manage pet dander in your home. Consider keeping your pets out of the bedrooms—especially the bedrooms of any allergy sufferers.

Signs of Pet Dander in Air Vents

The most common sign of pet dander in air vents is increased allergy symptoms. If you notice your allergy symptoms worsening but haven’t changed anything in your home (like adding another pet), your air vents might be to blame. Another sign of pet dander in air vents is seeing more dust and debris than usual in the home or noticing debris blowing out of the air vents.

Clogged air vents can also make your HVAC system work harder. Therefore, if you notice that your heating or AC is running more than usual or struggling to maintain a comfortable temperature, pet dander in the vents could be to blame. 

When to Call a Pro

With the right tools and supplies, cleaning your air vents can be a DIY project. However, DIY cleaning won’t remove lingering pet dander or dust deep in the ductwork. It’s best to leave air duct cleaning to the pros if you have excessive buildup or notice signs of mold or pest infestation in your air ducts.

A local air duct cleaning service will have the proper equipment to deep-clean your air vents and thoroughly remove pet dander from the ductwork. Air duct cleaning costs $270 to $510, with an average of $390.
