Why Hardwood Floors Are Better for Allergies Than Carpet
After 20+ years of installing and refinishing hardwood floors in PA and NJ, we've had a lot of conversations with homeowners about why they're ripping out their carpet. And one reason comes up more than almost anything else: allergies.
If you or someone in your house deals with allergies, asthma, or respiratory issues, your carpet might be making it worse. Here's what I've seen, based on hundreds of homes where we've pulled up old carpet and put down hardwood.
The Problem With Carpet and Allergies
Carpet is basically a giant filter sitting on your floor. And unlike the filter in your furnace that you change every few months, carpet just sits there collecting everything for years.
What gets trapped in carpet:
Dust mites (and their droppings, which are a major allergen)
Pet dander
Pollen tracked in from outside
Mold spores (especially if the carpet ever got wet)
Dust and dirt that settles deep into the fibers
You can vacuum all you want—and most people do—but vacuums only get surface-level stuff. The deeper particles stay trapped in the carpet padding and fibers. Over time, every step you take kicks some of that back up into the air you're breathing.
I've pulled up carpet that looked clean on the surface, and the amount of dust and debris underneath is shocking. Homeowners are always surprised. "We vacuumed regularly," they say. Yeah, but that doesn't get what's been accumulating for 10+ years.
Why Hardwood Floors Are Better
Hardwood doesn't trap allergens the same way carpet does. Dust, pollen, pet dander—it all sits on the surface where you can see it and clean it.
Here's what makes hardwood better for allergies:
1. Nothing hides in hardwood
There are no fibers for allergens to get trapped in. What lands on your floor stays on the surface. You can sweep it, vacuum it, or mop it away. It's gone.
With carpet, you're never really sure what's down there. With hardwood, you can see it, and you can remove it completely.
2. Dust mites hate hardwood
Dust mites need moisture and organic material to survive. Carpet provides both—fibers hold moisture, and dead skin cells (which we all shed constantly) get trapped in carpet and become food for dust mites.
Hardwood is a hostile environment for dust mites. It doesn't hold moisture the way carpet does, and there's nowhere for them to burrow and breed. They just don't thrive on hard surfaces.
If you're allergic to dust mites (and a lot of people are, even if they don't know it), getting rid of carpet is one of the best things you can do.
3. Pet dander doesn't accumulate
If you have pets, you know their hair and dander get everywhere. On carpet, that dander works its way deep into the fibers and stays there. Even after the pet is gone—if you rehome an animal or it passes away—the dander can remain in the carpet for years.
On hardwood, pet dander sits on the surface. You can sweep or vacuum it up daily. It doesn't build up the same way, and it doesn't linger after the pet is no longer in the house.
4. No mold or mildew issues
Carpet in basements, bathrooms, or anywhere that gets damp can develop mold and mildew. Even if you can't see it, the spores are there, and they get kicked into the air every time someone walks across the room.
Hardwood doesn't support mold growth the way carpet does. As long as you address any moisture issues in your home (which you should do regardless of flooring type), hardwood won't become a breeding ground for mold.
5. Easier to actually clean
Vacuuming carpet is maintenance. You're managing the problem, not solving it.
Cleaning hardwood is straightforward. Sweep, vacuum with a hard-floor attachment, or damp mop. You're removing allergens completely, not just pushing them around.
And if you spill something or track in mud? On carpet, that's a stain you're scrubbing for 20 minutes and hoping it comes out. On hardwood, you wipe it up and you're done. No residue, no moisture trapped underneath, no problem.
What Homeowners Tell Me After Switching
I've done a lot of projects where the main motivation was allergies. Usually it's a parent with a kid who has asthma, or someone who's been dealing with year-round sinus issues and finally connects it to the carpet.
After we install or refinish their hardwood, they almost always tell me the same thing: "I can breathe better."
Sometimes it's immediate—they notice the difference within a few days. Sometimes it takes a few weeks as the trapped allergens from the old carpet fully clear out of the house. But the improvement is real.
One client told me her daughter's asthma attacks dropped by half after we pulled up the carpet in the bedrooms and refinished the hardwood underneath. Another said he stopped waking up congested every morning for the first time in years.
I'm not a doctor, and I can't promise hardwood will cure your allergies. But I can tell you that a lot of people see a noticeable improvement when they get rid of carpet, and the research backs that up.
What About Area Rugs?
People ask this all the time: "If I get hardwood, can I still use area rugs?"
Yes, you can. And area rugs are way better than wall-to-wall carpet for allergies, for a few reasons:
1. You can take them outside and shake them out or beat them. Try doing that with carpet.
2. You can wash smaller rugs in a machine or take larger ones to be professionally cleaned more easily than cleaning an entire carpeted room.
3. You can remove them entirely if allergies flare up, or during high-pollen seasons.
Area rugs give you the comfort and warmth of carpet in specific spaces without turning your entire floor into an allergen trap.
What If You're Worried About Dust on Hardwood?
Some people worry that hardwood will show more dust than carpet, and that's true—you'll see it. But that's actually a good thing.
With carpet, the dust is there whether you see it or not. It's just hidden. With hardwood, you see it, which means you're reminded to clean it, and when you do clean it, it's actually gone.
If you're worried about constantly sweeping, here's what works:
Get a good microfiber dust mop and run it over high-traffic areas daily (takes two minutes)
Use a vacuum with a hard-floor setting a couple times a week
Damp mop as needed (not soaking wet, just lightly damp)
It's less work than vacuuming carpet, and it's more effective at actually removing allergens.
Hardwood Isn't Perfect for Everyone
I'm not going to tell you hardwood is the answer to every problem. There are a few things to consider:
Cost: Hardwood costs more upfront than carpet. If you're on a tight budget, it's a bigger investment. But it lasts longer and doesn't need replacing every 10 years like carpet does, so over time the cost evens out.
Comfort: Carpet is softer underfoot. Some people prefer the cushion, especially in bedrooms. If that matters to you, hardwood with area rugs is a good compromise.
Noise: Hardwood is louder than carpet. Footsteps echo more. If you live in a multi-story home or have downstairs neighbors, this can be an issue. Area rugs help, or you can add underlayment for sound dampening.
But if allergies are the main concern? Hardwood wins every time.
The Bottom Line
If you or someone in your household struggles with allergies, asthma, or respiratory issues, getting rid of carpet and switching to hardwood can make a real difference.
Hardwood doesn't trap dust, pollen, pet dander, or dust mites. It's easier to keep clean. And it doesn't harbor mold or mildew the way carpet can.
After two decades of doing this work, I've seen the difference it makes for people. It's not just about how the floors look—though that's a nice bonus. It's about being able to breathe easier in your own home.
