If you have a furry family member, chances are you’ve wondered about how to get rid of pet dander in your home. There’s so much to love about having a dog or a cat, but the allergens they generate can make things less than ideal for their human companions.
Pet dander is similar to dandruff, except it occurs on dogs, cats, and birds. Like pet fur, pet dander clings to surfaces and can be very hard to remove. The American Lung Association warns that these tiny skin flakes can spark sneezing, watery eyes, rashes, or even asthma flare-ups in people who are sensitive. Reducing dander is therefore a health step as much as a cleaning chore—and a few simple habits can let you enjoy your pets without letting their dander take over your home. Luckily, there are tips you can follow to live with animals without letting their pet dander get to you.
It turns out, dander can stay around long after a pet is no longer in a home. Pet dander can remain in a house up to 4-7 months after a pet is gone. That means if you move into a new home, you could be affected even if you don’t have a pet of your own. It also means new dander from your furry friend isn’t likely to go away by itself.
Even though weekly baths can cut pet dander by up to 84 % the remaining allergens can still cause problems. The best advice we have to give is to take a comprehensive approach. Getting rid of pet dander requires different solutions for different areas of the home.
Carpets and pets don’t go together for several reasons, and pet dander is one of them. Ideally, allergy sufferers will have limited carpet in the home since it traps allergens that can build up over time.
Other than ripping out the carpet altogether, the best solution to get rid of pet dander is regular cleaning. These tips will help you remove more pet dander every time, so break out the vacuum.
While you’re at it, you may want to use the vacuum cleaner on the floor rugs, curtains, and pet bedding. Better yet, put them in the washing machine if they are machine-washable.
One spot where pet dander can accumulate is on the couch—even if you don’t allow pets on the furniture. Here's how to keep your sofa free of pet dander:
Like the carpets, the couch is going to need regular cleaning to keep the pet dander under control. And if your cat or dog currently lounges on the couch, you may want to consider getting them their own bed for the living room so they stay off the furniture.
Pet dander isn’t just in the air. It’s also in your HVAC system and air ducts. It can be especially problematic if you don’t have adequate air filters or your filter is overdue for a change.
If you schedule an HVAC check annually, air-duct cleaning may be part of the service. The technician has a specialty vacuum that can get into the ductwork and suck out dirt, debris, and pet dander. You can help keep the air ducts clean by wiping down air vents and registers that can collect dust and particles.Set a reminder to change the HVAC filter every month if pets spend most of their time indoors.
The filtering grade of your HVAC filter (also known as your MERV rating) aids in removing pet dander from your HVAC system. Filterbuy carries MERV 8, 11, and 13 options, so you can match the filter to your system’s airflow and allergy needs.
A MERV rating of 10-13 is a sweet spot for residential use. At this rating, air filters can clear 95-98 % of airborne particles, including pet dander, while still allowing adequate airflow. Higher ratings can restrict airflow and may not suit every residential unit.
Filter fit is extremely important for air purification. An air filter that’s too large will be loose, allowing air to pass without going through the filter. Choose the exact size and replace the filter every 30–60 days if pets stay indoors; otherwise, every three months is usually sufficient.

HEPA filters are known for capturing 99.97 % of particles as small as 0.3 microns. Because this media is very dense, it can restrict airflow if installed in a central HVAC system. Instead, place a portable HEPA purifier in living rooms or bedrooms where pets spend the most time. This adds localized filtration without stressing your main equipment.

Remove loose dander at the source—bathe or brush the pet outdoors—then vacuum with a sealed HEPA machine and run a portable air purifier for at least an hour.
Yes. High-efficiency filters—MERV 11 or higher—capture the tiny dander particles ordinary filters miss. Change the filter every 30–60 days for the best results.
Vacuum with a HEPA unit two or three times a week, dust with microfiber cloths, and wash bedding (yours and your pet’s) weekly. Regular grooming keeps shedding under control before dander spreads.
Absolutely. A portable HEPA purifier cuts airborne dander in rooms where pets spend the most time and works well alongside your central HVAC filter.
No. Pets constantly shed skin flakes, so dander levels rebound within days unless you groom, clean, and change filters regularly.
Damp dusting, HEPA filtration, and enzyme-based cleaners break down the proteins that cause most dander allergies.
Enzyme sprays labeled for pet-allergy relief break down dander proteins on fabric and hard surfaces; follow label directions for dwell time.
Sunlight and fresh air help, but the most effective natural methods are weekly baths, frequent brushing, and regular laundering of pet bedding.
Use a lint roller, vacuum crevices with the upholstery tool, then wipe fabric with a lightly damp microfiber cloth or steam-clean if safe for the material.
Common reactions include sneezing, runny nose, itchy or watery eyes, skin rashes, and in some people, asthma flare-ups.
Individual flakes are microscopic, but on dark surfaces they appear as light, dust-like specks that cling to fabric and static-charged electronics.
Vinegar will not “kill” dander proteins, but a 50/50 vinegar-water mix can help loosen residue so you can wipe it away.
Yes—if you use a sealed HEPA vacuum and empty or replace the bag outdoors; standard vacuums often blow fine dander back into the room.
Combine weekly grooming, HEPA filtration, a no-pet bedroom rule, and physician-recommended allergy meds or immunotherapy to stay comfortable while keeping your pet.
