Household Products That Could Be Making Your Allergies Worse

1. Scented Candles

Scented candles are a popular way to create a cozy, fragrant atmosphere at home. However, burning these candles—even those from well-known brands such as Yankee Candle—can release volatile organic compounds (VOCs) into the air. VOCs, including formaldehyde, benzene, and toluene, are known to irritate the respiratory system and can significantly worsen allergy symptoms. According to the U.S. Environmental Protection Agency (EPA), exposure to VOCs indoors may trigger headaches, coughing, sneezing, and even asthma attacks, especially in those who are allergy-prone.

Scented candles often use synthetic fragrances and paraffin wax, which, when burned, release more irritants into the air. These airborne particles can linger, making it difficult for allergy sufferers to find relief, even hours after extinguishing the flame. To reduce exposure to these hidden triggers, opt for unscented candles or those made with natural materials like beeswax or soy wax. Alternatively, consider natural air freshening methods such as opening windows or using air purifiers designed for allergy sufferers. These small changes can make a significant difference in keeping your indoor air cleaner and allergy symptoms at bay.

2. Air Fresheners

Air fresheners are marketed as a quick fix to eliminate odors, but the synthetic fragrances they contain can be a significant source of indoor allergens. Many air fresheners, both plug-in and spray varieties, release chemicals called phthalates—substances associated with hormone disruption and aggravated allergy symptoms. According to the Natural Resources Defense Council (NRDC), phthalates and other volatile organic compounds can cause sneezing, coughing, and eye or throat irritation, particularly in sensitive individuals.

There are differences between plug-in and spray air fresheners. Plug-in types tend to emit a continuous low-level release of fragrance and chemicals, while sprays deliver a concentrated burst that lingers in the air. Both types can exacerbate allergy symptoms, but sprays may result in higher immediate exposure to irritants. To minimize risk, choose fragrance-free or naturally scented options that disclose all ingredients. Improving ventilation by opening windows or using exhaust fans can further help reduce airborne allergens. The CDC recommends keeping indoor air as clean and fresh as possible, especially for allergy-prone individuals.

3. Laundry Detergents

Many conventional laundry detergents contain dyes and artificial fragrances that can linger on clothing and bedding, coming into close contact with skin and airways. These additives are known to trigger allergic reactions, such as itchy skin, hives, and even respiratory irritation in sensitive individuals. According to the American Academy of Dermatology, detergents are among the most common causes of contact dermatitis, especially for those with pre-existing allergies or eczema.

For those with sensitive skin or allergies, sensitive skin formulas that are free from dyes and perfumes can make a significant difference. Brands like Tide Free & Gentle and Seventh Generation Free & Clear are popular choices among allergy sufferers. To further minimize residue, consider running a double rinse cycle—this helps wash away any lingering irritants that may not be removed in a single wash. Opting for hypoallergenic products can also provide peace of mind and reduce the risk of allergic flare-ups. Taking these small steps can help ensure your clothing and bedding are truly clean and safe for allergy-prone households.

4. Fabric Softeners

Fabric softeners are often marketed as a way to make laundry feel softer and smell fresher, but their chemical composition can spell trouble for allergy sufferers. Many fabric softeners contain quaternary ammonium compounds (quats) and artificial fragrances, both of which are known to trigger eczema flare-ups and worsen respiratory allergies. According to the Asthma and Allergy Foundation of America (AAFA), these ingredients can cause skin irritation, rashes, and in some cases, provoke coughing or wheezing in those with asthma.

A common reaction is the sudden onset of itchy, red patches after wearing freshly washed clothes—often mistaken for a detergent allergy when it’s actually due to the fabric softener. To avoid such issues, consider switching to alternatives like wool dryer balls, which naturally soften fabrics and reduce static without harmful chemicals or scents. The American Academy of Dermatology also recommends skipping fabric softeners entirely if you have sensitive skin or a history of allergic reactions. This simple change can make a noticeable difference in the comfort and health of your household.

5. Carpets and Rugs

Carpets and rugs may add warmth and style to your home, but they are notorious for trapping dust mites, pet dander, and mold spores—all common indoor allergens. Over time, these particles accumulate deep within the fibers, making them difficult to remove with regular cleaning. According to the Centers for Disease Control and Prevention (CDC), dust mites are a leading trigger for allergy and asthma symptoms, especially in homes with wall-to-wall carpeting.

Compared to hard flooring such as tile or wood, wall-to-wall carpet creates a more hospitable environment for allergens. Hard floors are easier to clean and do not harbor as many microscopic irritants. If you prefer the comfort of rugs, opt for smaller, washable options and launder them regularly. Using a HEPA-filter vacuum can help remove allergens from carpets and rugs more effectively. For added protection, consider allergen-proof mats or covers that reduce the buildup of particles. Simple changes to your cleaning routine and flooring choices can significantly lower allergen levels and make your home a safer haven for allergy sufferers.

6. Upholstered Furniture

Sofas, armchairs, and other upholstered furniture might look inviting, but they can be major reservoirs for allergens such as dust mites, pet dander, pollen, and mold spores. The soft, porous surfaces of fabric furniture make it easy for these particles to settle in and accumulate over time. According to the Asthma and Allergy Foundation of America (AAFA), upholstered furniture can be a persistent problem for those with allergies, especially if it’s not cleaned regularly.

Consider the scenario of an older couch handed down from a relative: Despite appearing clean, it may be harboring years’ worth of dust and allergens deep within its cushions and seams. Sitting or lying on such furniture can release these trapped particles into the air, triggering sneezing, coughing, or itchy eyes. To combat this, use washable covers that can be laundered frequently. Regular vacuuming with a HEPA filter attachment is also essential for reducing allergen buildup. In addition, periodic deep cleaning or steam cleaning can further help keep your upholstered furniture fresh and safe for allergy-prone individuals.

Pillows and bedding are prime habitats for dust mites, microscopic creatures that thrive in warm, humid environments and feed on skin flakes. Over time, these allergens accumulate and can become a significant trigger for nighttime allergy flare-ups. It’s common for allergy sufferers to experience increased sneezing, congestion, or itchy eyes when they settle into bed—often due to the close contact with dust mite-laden bedding.

According to the Centers for Disease Control and Prevention (CDC), dust mites are a leading cause of allergic reactions in the home, particularly in bedding and pillows. To combat this, use allergen-proof covers for pillows and mattresses, which create a barrier against mites and their waste. Regularly washing sheets, pillowcases, and blankets in hot water (at least 130°F) can further reduce dust mite populations. Consider replacing old pillows every couple of years, as they tend to harbor higher concentrations of allergens over time. By combining these strategies, you can greatly decrease nighttime allergen exposure and enjoy more restful, symptom-free sleep.

8. Mattresses

Mattresses, regardless of type, are a hidden source of allergens such as dust mites, pet dander, and even mold spores. Over time, these particles settle deep into the layers of the mattress, making them difficult to remove with conventional cleaning. Both memory foam and traditional spring mattresses can harbor allergens, though memory foam tends to be less hospitable to dust mites due to its dense structure. However, no mattress is completely immune.

The Asthma and Allergy Foundation of America (AAFA) emphasizes the need for mattress encasements that are specifically designed to be allergen-proof. These encasements create a physical barrier, preventing the accumulation and escape of dust mites and other irritants. Additionally, periodically sunning out your bedding and mattress helps reduce moisture, making the environment less attractive to dust mites and mold. Vacuuming the mattress surface and rotating it regularly can also help minimize buildup. These preventive steps, coupled with frequent washing of all bedding, can significantly reduce allergen levels in the bedroom and provide much-needed relief for allergy sufferers.

9. Vacuum Cleaners

While vacuuming is essential for keeping dust and allergens at bay, not all vacuum cleaners are created equal. Bagless or low-filtration models can actually release fine particles back into the air as they operate, inadvertently worsening allergies instead of improving them. Traditional vacuum cleaners with standard filters may not effectively trap microscopic irritants like dust mites, pollen, or pet dander.

In contrast, HEPA (High Efficiency Particulate Air) filters are designed to capture 99.97% of particles as small as 0.3 microns, significantly reducing airborne allergens. According to the U.S. Environmental Protection Agency (EPA), vacuums with genuine HEPA filters and sealed systems prevent allergens from escaping back into the home environment. When shopping for a vacuum, look for models explicitly labeled as “sealed HEPA” to ensure maximum effectiveness. These machines trap and contain allergens much better than their standard counterparts, making them a wise investment for allergy sufferers. Regularly maintaining and replacing vacuum filters as recommended will further ensure your machine continues to protect your home’s air quality.

10. Cleaning Sprays

Many household cleaning sprays contain harsh chemicals such as ammonia and bleach, which can irritate the airways and worsen allergy or asthma symptoms. When sprayed, these chemicals become airborne, increasing the risk of inhalation and immediate respiratory discomfort. Even short-term exposure can provoke coughing, throat irritation, or wheezing in sensitive individuals.

Research published in the American Journal of Respiratory and Critical Care Medicine found a direct association between frequent use of spray cleaning agents and the development or exacerbation of asthma. The fine mist created by these sprays allows volatile compounds to linger in the indoor air, posing a risk to anyone nearby. To minimize these hazards, opt for fragrance-free and safer cleaning products that avoid harsh chemicals. The CDC recommends using mild soap and water or products specifically labeled as non-irritating for those with respiratory sensitivities. These choices can significantly reduce chemical exposure and help maintain a healthier home environment for allergy-prone individuals.

Attic insulation, particularly the fiberglass variety, is a hidden source of dust and airborne fibers that can aggravate allergies and cause respiratory irritation. Disturbing insulation during home repairs or inspections releases tiny particles that are easily inhaled, leading to coughing, sneezing, or itching. Fiberglass insulation can also trap dust, pollen, and, in damp attics, even mold spores—compounding the risk of allergic reactions.

The National Institute for Occupational Safety and Health (NIOSH) provides guidelines on safe handling of insulation materials, emphasizing the importance of wearing protective masks, gloves, and clothing when entering attic spaces. Wearing a high-quality mask or respirator during inspection or maintenance can significantly reduce the risk of inhaling allergenic particles. After attic work, shower and change clothes to avoid spreading fibers throughout your home. Taking these precautions helps ensure your home’s insulation does its job without compromising your indoor air quality or your health.

39. Hobby Supplies

Hobby and craft supplies—such as glues, paints, and modeling clays—often contain a variety of chemicals and allergens. Solvents, latex, and preservatives in these materials can release fumes or dust particles that trigger allergic skin reactions, headaches, or respiratory irritation. For example, some craft glues contain formaldehyde or toluene, while certain paints and dyes use volatile organic compounds (VOCs) as solvents.

Practicing safe crafting is especially important for allergy-prone individuals, children, and anyone working in enclosed spaces. The U.S. Consumer Product Safety Commission (CPSC) recommends working in a well-ventilated area, wearing gloves, and choosing non-toxic or hypoallergenic supplies when possible. Always store hobby materials in tightly sealed containers and away from living spaces to limit accidental exposure. Good ventilation—such as opening windows or using exhaust fans—can significantly reduce indoor air pollution from crafting activities, ensuring that creativity doesn’t come at the expense of your health.

40. Scented Lotions

Scented lotions are a common culprit behind fragrance-induced skin allergies and irritation. Many contain artificial perfumes, essential oils, or preservatives that can lead to contact dermatitis—resulting in redness, itching, or rashes, especially for those with sensitive skin or existing allergies. Frequent use of these products can compound symptoms over time, making daily comfort and skincare a challenge.

Hypoallergenic brands such as Cetaphil and Vanicream are formulated without common allergens, prioritizing gentle, soothing ingredients over added fragrances. According to the American Academy of Dermatology (AAD), choosing fragrance-free lotions is the safest option for those prone to allergies or eczema. Always check labels for hidden fragrance ingredients and opt for products specifically labeled as “fragrance-free” or “for sensitive skin.” Making this switch can help reduce the risk of skin reactions and keep your daily moisturizing routine both safe and comfortable.

41. Hair Sprays

Hair sprays, particularly those in aerosol form, are a frequent source of aerosolized chemicals and fragrance allergens in the home. These products often contain alcohols, formaldehyde-releasing agents, and synthetic scents that can linger in the air, triggering headaches, sneezing, or even asthma symptoms in sensitive individuals. The fine mist can easily spread throughout small indoor spaces, making bathrooms a hotspot for exposure.

For example, spraying hair products in a poorly ventilated bathroom can leave lingering fumes that affect anyone entering the room shortly afterward. According to the Asthma and Allergy Foundation of America (AAFA), fragrance chemicals in personal care products are a common trigger for allergies and respiratory irritation. To minimize risk, always spray hair products in a well-ventilated area—open a window, use an exhaust fan, or step outside if possible. These simple precautions can help reduce airborne irritants and make your grooming routine safer for everyone in your household.

42. Nail Polish Remover

Nail polish removers commonly contain acetone or other strong solvents that can irritate the eyes, nose, throat, and skin. The fumes from acetone-based removers are especially potent and can trigger headaches, dizziness, or respiratory discomfort, particularly in those with allergies or chemical sensitivities. Non-acetone removers, while often marketed as gentler, still contain chemicals like ethyl acetate, which can cause similar reactions.

Comparing remover types, acetone-based products tend to work faster but have stronger odors and a higher potential for irritation, while non-acetone versions may require longer exposure and repeated application. According to the American Academy of Dermatology (AAD), using these products in confined, poorly ventilated areas increases the risk of adverse reactions. Always use nail polish remover in a well-ventilated space—open windows, turn on fans, or step outdoors to allow fumes to dissipate quickly. Taking these precautions can help minimize irritation and make your nail care routine safer for allergy-prone individuals.

43. Perfumed Candles

Perfumed candles are a favorite for creating ambiance, but their scented wax and wicks can introduce airborne allergens and irritants into your home. When burned, these candles release not only their fragrance but also volatile organic compounds (VOCs), soot, and sometimes even trace heavy metals from certain wicks. These emissions can aggravate respiratory symptoms, especially in allergy and asthma sufferers.

A 2023 study published in the International Journal of Environmental Research and Public Health found that burning scented candles indoors is associated with increased indoor air pollution and higher reports of eye, nose, and throat irritation among occupants. To reduce these risks, consider beeswax or soy-based candles with cotton wicks and no added fragrances. These alternatives produce fewer emissions and are less likely to trigger allergy symptoms. By making this simple switch, you can still enjoy cozy candlelight without compromising your indoor air quality or well-being.

44. Room Sprays

Room sprays are a quick solution for masking odors, but they often contain synthetic fragrances, VOCs, and preservatives that can trigger allergy symptoms or worsen asthma. These ingredients linger in the air and on surfaces, increasing the risk of headaches, sneezing, or respiratory discomfort for sensitive individuals. Even “natural” or botanical sprays may contain essential oils that act as allergens for some people.

When comparing types, aerosol sprays create a fine mist that disperses quickly and stays suspended in the air longer, leading to prolonged exposure. Pump sprays, while less forceful, can still contribute to airborne irritants if used in excess. According to the Asthma and Allergy Foundation of America (AAFA), reducing the use of fragranced products is key to minimizing allergy triggers. Whenever possible, air out rooms by opening windows and using fans after using room sprays. Choosing fragrance-free or hypoallergenic alternatives can further help you maintain a fresh, allergy-friendly indoor environment.

45. Incense

Burning incense sticks is a popular ritual for creating a calming atmosphere or masking odors, but it comes with notable allergy risks. Incense smoke contains particulate matter, VOCs, and a range of byproducts that can irritate the respiratory system. Sensitive individuals may experience coughing, sneezing, or worsening asthma symptoms after exposure, even if the incense is used only occasionally.

The World Health Organization (WHO) highlights that indoor air pollution from burning incense, candles, or wood is a significant contributor to poor air quality and respiratory health problems worldwide. Fine particles generated by incense are especially problematic in small or poorly ventilated spaces, where they can linger for hours. It is wise to limit the use of incense indoors, ensure good ventilation when burning it, and consider alternative methods—such as electric diffusers with hypoallergenic oils or simply airing out rooms. These steps can help reduce the impact of indoor air pollution and keep your home safer for allergy-prone occupants.

46. DIY Cleaning Solutions

Many people turn to DIY cleaning solutions as a safer alternative to commercial cleaners, but “natural” does not always mean non-allergenic. Ingredients like citrus oils, tea tree oil, or even baking soda can provoke allergic reactions or skin irritation in sensitive individuals. For instance, citrus-based oils are common triggers for contact dermatitis, leaving some people with rashes or itching after use.

Vinegar and baking soda are two of the most popular DIY cleaning ingredients. While generally considered safe, vinegar’s strong odor may still cause respiratory discomfort or headaches, while baking soda can be abrasive and irritating to some skin types. According to the American Academy of Dermatology (AAD), it’s wise to patch test any new homemade cleaner on a small area of skin or surface before widespread use. Always dilute essential oils and wear gloves if you have a history of sensitivities. Taking these precautions can help you enjoy the benefits of DIY cleaners without inadvertently worsening allergy symptoms.

47. Plastic Food Containers

Plastic food containers are a staple in many kitchens, but some varieties can leach chemicals such as BPA (bisphenol A) and phthalates into food, especially when heated. These chemicals are known endocrine disruptors and may also act as allergens or sensitizers for some individuals, contributing to skin irritation, headaches, or respiratory symptoms.

The U.S. Food and Drug Administration (FDA) has issued advisories about BPA, especially for infants and young children, and encourages the use of BPA-free products. While many manufacturers now offer BPA-free plastics, some still contain other chemicals that can cause similar concerns. To minimize risk, opt for glass food storage containers or clearly labeled BPA-free plastic alternatives. Avoid microwaving food in plastic containers unless they are specifically marked as microwave-safe. These simple changes can help reduce chemical exposure and potential allergy risks in your kitchen, contributing to a healthier household environment.

48. Nonstick Cookware

Nonstick cookware, especially pans coated with Teflon (polytetrafluoroethylene or PTFE), is prized for easy cleanup and low-fat cooking. However, when overheated, these pans can emit fumes containing potentially harmful chemicals such as perfluorooctanoic acid (PFOA) and other fluorinated compounds. These fumes can cause polymer fume fever, a flu-like reaction, and may aggravate asthma or allergy symptoms in sensitive individuals.

Imagine accidentally leaving a nonstick pan on a hot stove, filling the kitchen with a distinct odor and causing coughing or breathing discomfort for anyone nearby. According to the Agency for Toxic Substances and Disease Registry (ATSDR), fumes from overheated Teflon can pose respiratory risks, especially in poorly ventilated spaces. To minimize exposure, always use nonstick pans in well-ventilated areas and avoid preheating them empty or using them at high temperatures. These habits will help keep your kitchen air cleaner and reduce the risk of allergic or respiratory reactions while cooking.

49. Air Purifiers (Unmaintained)

Air purifiers are designed to improve indoor air quality, but if their filters are not cleaned or replaced regularly, they can become breeding grounds for mold, bacteria, and trapped allergens. Once saturated, dirty filters may even start releasing these irritants back into the air, making allergy symptoms worse rather than better.

HEPA (High-Efficiency Particulate Air) filters are the gold standard, capturing 99.97% of particles as small as 0.3 microns. Non-HEPA filters, by comparison, are less effective at trapping fine allergens and may clog more quickly. According to the U.S. Environmental Protection Agency (EPA), regular filter replacement—as often as every 3-6 months, depending on usage and manufacturer guidelines—is essential for keeping air purifiers effective and preventing microbial buildup. Always follow the device’s maintenance instructions and check the filter status indicator if available. With proper care, air purifiers can truly help reduce allergy triggers and keep your home’s air clean and safe.

50. Indoor Paint Strippers and Solvents

Indoor paint strippers and solvents—such as turpentine, methylene chloride, and toluene—release potent chemical fumes that can cause immediate irritation to the eyes, nose, throat, and lungs. For individuals with allergies or respiratory sensitivities, even brief exposure can trigger headaches, dizziness, coughing, or asthma attacks. The risk intensifies in enclosed or poorly ventilated spaces, where fumes can build up quickly.

Imagine a DIY renovation project involving old paint removal in a small bathroom. Without proper ventilation, the strong smell can linger and provoke symptoms for everyone in the home. According to the Centers for Disease Control and Prevention (CDC), many paint strippers and solvents are classified as hazardous and should be handled with extreme care. Always use these products outdoors or in well-ventilated areas—open windows, use exhaust fans, and wear a mask or respirator if needed. These precautions help reduce the risk of allergic reactions, keeping your living environment safer during remodeling or repair projects.
