When your own home leaves you sneezing, congested, or dealing with itchy, watery eyes, everyday life can become uncomfortable pretty quickly. Indoor allergens such as dust mites, pet dander, mold, and pollen can collect in the places where families spend the most time, including bedrooms and living areas. For an even broader approach, these tips to improve the air quality at home can help you look at ventilation, humidity, and other factors that affect your home's indoor environment.
While you can't make a home completely allergen-free, you can take practical steps to reduce your exposure to common indoor allergy triggers. These three changes are relatively simple places to start, whether you're trying to make your bedroom more comfortable or create a healthier-feeling home for the entire family.
This article shares general household information and is not a substitute for medical advice. If allergy or asthma symptoms are persistent, severe, or interfere with daily life, talk with a qualified healthcare professional.
1. Use Allergen-Proof Mattress and Pillow Covers
If dust mites are one of your allergy triggers, the bedroom is a smart place to focus your efforts.
Dust mites commonly live in mattresses, bedding, upholstered furniture, and carpets. Because we spend so many hours sleeping, reducing exposure in the bedroom can be an important part of an allergy-management routine.
Consider covering mattresses and pillows with zippered, dust-mite-resistant or allergen-proof covers. These covers create a barrier between you and allergens that may be present in bedding.
Don't stop with the covers, though. Wash sheets and other washable bedding regularly according to their care instructions. Keeping indoor humidity under control can also make your home less hospitable to dust mites.
For families with children who have allergies, don't forget about stuffed animals and other soft items that spend a lot of time on the bed. Washable items are generally easier to keep clean and free of accumulated dust.
2. Consider an Artificial Christmas Tree
If your allergy symptoms seem to get worse around the holidays, your Christmas decorations may deserve a closer look.
A live Christmas tree isn't necessarily an allergen itself. However, natural trees can carry microscopic mold spores, while their fragrance may also be irritating for some people with allergies or asthma.
For families who notice symptoms whenever a live tree comes indoors, an artificial Christmas tree may be worth considering.
Several companies make artificial trees designed to mimic the appearance of natural evergreens. Balsam Hill, for example, offers artificial Christmas trees in a wide range of styles and sizes.
An artificial tree isn't automatically allergen-free, however. Dust can accumulate on artificial trees and decorations while they're stored for the year. Before decorating, wipe down or clean your tree as appropriate and consider storing holiday decorations in closed containers to limit dust buildup.
If your family prefers a real tree, you don't necessarily have to give up the tradition. The American Academy of Allergy, Asthma & Immunology suggests allowing a real tree to dry in a garage or enclosed porch and giving it a good shake before bringing it indoors.
3. Choose Hard Flooring When It Makes Sense
Carpet can make a room feel warm and cozy, but it can also collect dust, dust-mite allergens, pet dander, pollen, and other particles.
If someone in your household has significant indoor allergies, replacing wall-to-wall carpet with a hard flooring surface may make allergens easier to remove during routine cleaning. Hardwood is one option, but other easy-to-clean hard flooring can serve the same practical purpose. If you already have wood floors, these pointers for cleaning wooden floors can help you keep them looking their best as part of your regular home-cleaning routine.
Of course, replacing flooring throughout an entire house is a major project. If a whole-home renovation isn't realistic, consider starting with the bedroom, where reducing dust-mite exposure can be particularly helpful.
Whether you have carpet or hard floors, regular cleaning still matters. Vacuum carpeting and upholstered furniture regularly, preferably using a vacuum equipped with an appropriate high-efficiency filter, and clean hard surfaces with a damp cloth or mop so you're removing dust instead of simply sending it back into the air.
More Ways to Reduce Indoor Allergy Triggers
These three changes can be a good starting point, but they work best as part of a broader approach to indoor allergen control.
Keep moisture problems under control and address leaks promptly to discourage mold growth. Aim for reasonable indoor humidity, clean accumulated dust regularly, and pay extra attention to bedrooms and other rooms where your family spends a lot of time.
Indoor humidity can be a balancing act, especially during colder months when heating systems can leave the air uncomfortably dry. These simple habits for staying comfortable through winter offer additional ideas for managing indoor air and humidity during heating season.
If you have pets, regular cleaning can help reduce the amount of pet allergen that collects on floors, furniture, and other household surfaces. Depending on a family member's specific allergies, keeping pets out of that person's bedroom may also help reduce exposure.
Most importantly, remember that the goal isn't a perfectly allergen-free house. That's not realistic. The goal is to identify the triggers that affect your household and reduce exposure where you reasonably can.
Frequently Asked Questions About Indoor Allergies
What are the most common indoor allergy triggers?
Common indoor allergens include dust mites, pet allergens, mold, pollen that makes its way indoors, and allergens associated with pests such as cockroaches and rodents.
Can dust mites live in mattresses and pillows?
Yes. Dust mites thrive in warm, humid environments and are commonly found in bedding, mattresses, upholstered furniture, and carpets. Allergen-proof mattress and pillow covers can help reduce exposure.
Are artificial Christmas trees better for allergies?
They can be helpful for people whose symptoms are triggered by mold spores or irritants associated with live Christmas trees. However, artificial trees can collect dust while in storage, so they should be cleaned before being brought into your living space.
Is hardwood flooring better than carpet for allergies?
Hard flooring is generally easier to clean and doesn't provide the same reservoir for dust and dust-mite allergens as wall-to-wall carpeting. For people with dust-mite allergies, allergy specialists often recommend hard flooring instead of carpet when practical, particularly in bedrooms.
Can you completely eliminate allergens from your home?
Probably not. Dust, pollen, mold spores, pet allergens, and other particles can enter or develop in a home in many different ways. A more realistic goal is to reduce exposure through regular cleaning, moisture control, appropriate bedding covers, and other changes targeted to your particular allergy triggers.
A Few Last Home Notes
Indoor allergies don't necessarily require a complete home makeover. Small, targeted changes can make your living spaces easier to keep clean and may reduce exposure to the allergens that bother your family most.
Start where you spend the most time. Protect mattresses and pillows if dust mites are a concern, reconsider holiday decorations if symptoms consistently flare during Christmas, and choose easy-to-clean flooring when you're already planning a renovation.
And if symptoms continue despite changes at home—or if anyone in your family experiences wheezing, shortness of breath, or other significant respiratory symptoms—talk with a healthcare professional or allergist. Identifying the actual trigger is far more useful than trying to remove everything from your home that might be causing a reaction.
