Suffering from allergies and asthma every time you step into your own home is frustrating and distressing. However, there are ways to counteract indoor allergens and improve your living space. With some diligence and smart solutions, you can breathe easier in a home tailored to your needs.

What Causes Indoor Allergies and Asthma?

Indoor allergies and asthma flare-ups stem from a variety of triggers lurking in your home environment. Here are some of the most common culprits:

  • Dust mites – Microscopic dust mites feed on flakes of dead skin and thrive in carpet, bedding, stuffed animals, and upholstered furniture. Their feces and decaying bodies cause allergic reactions.
  • Mold – Excess moisture allows mold spores to grow on surfaces like walls, tiles, wood, and carpet. Inhaling mold spores can cause wheezing and congestion.
  • Pets – Pet dander, hair, and saliva trigger allergic reactions and asthma symptoms in sensitive individuals. Cats and dogs tend to be more problematic than hypoallergenic pets.
  • Pests – Cockroaches and rodents spread allergens through skin flakes, feces, and saliva. Their presence points to unclean conditions ideal for allergens.
  • Chemicals – Cleaning products, air fresheners, paint, and more contain harsh fumes. Volatile organic compounds (VOCs) aggravate respiratory conditions.
  • Smoke – Secondhand smoke from tobacco products, candles, or fireplaces introduces allergens and irritants into home air.
  • Pollen – Outdoor allergens enter through open windows and cling to clothing and fur. Tree, grass, and weed pollen in your home can cause issues.

Being aware of these common allergy and asthma triggers is the first step toward creating a healthier indoor haven.

Tips to Allergyproof Your Home

With some diligent cleaning, minor upgrades, and lifestyle adjustments, you can dramatically reduce allergy triggers at home. Here are some effective tips:

Use Air Purifiers

Investing in quality high-efficiency particulate air (HEPA) purifiers for your bedroom and main living areas cleans allergens from the air. Change filters regularly. Portable purifiers help sanitize problem zones.

Control Moisture

Fix any leaks, maintain proper ventilation, use dehumidifiers, and avoid excessive houseplants. Controlling dampness inhibits mold growth.

Choose Allergy-Friendly Bedding

Hypoallergenic covers, microfiber sheets, and duvets help reduce dust mites. Wash bedding weekly in hot water. Replace pillows regularly.

Vacuum Often

Use a vacuum with a HEPA filter to thoroughly clean carpets, drapes, and furniture. This removes allergens from surfaces before they circulate.

Remove Carpets and Upholstery

Hardwood, tile, and washable rugs trap less dust than wall-to-wall carpeting. Leather and vinyl furniture is better than fabric.

Clean Regularly

Dust, wipe surfaces, wash bedding, and vacuum frequently. Use gentle, unscented cleaners. Disinfect problem areas like bathrooms.

Create Pet-Free Zones

Keep pets out of bedrooms and restrict them to non-carpeted areas of your home. Bathe pets weekly and brush them outdoors.

Improve Air Flow

Open windows regularly to circulate fresh air. Make sure vents aren’t obstructed by furniture or dust. Change HVAC filters often.

Use a Dehumidifier

Excess moisture makes an ideal environment for mold, mildew and dust mites. Dehumidifiers can help regulate humidity.

Wash Bedding Frequently

Dust mites thrive in bedding. Wash sheets, pillowcases, duvet covers and blankets at least once a week in hot water to kill them.

Seal Cracks and Crevices

Caulk and seal any cracks or openings throughout the home to prevent pests from entering and nesting in walls and basements.

Add Houseplants

Some plants like aloe vera, English ivy and spider plants help purify indoor air of pollutants. Avoid ferns and flowers which can aggravate allergies.

Frequently Asked Questions

How can I tell if my home has high allergen levels?

Signs of high allergen levels include seeing visible mold growth, pest droppings, excessive dust on surfaces, musty odors, and increased allergy/asthma symptoms when at home. Air quality testing can detect problematic spore and particle counts.

Should I get rid of my carpeting?

For severe allergies, removing wall-to-wall carpeting greatly reduces dust mite and pet dander buildup. Hard flooring that can be swept and mopped is ideal. Washable area rugs are an option for adding warmth.

What type of vacuum is best for allergies?

Look for vacuums with superior HEPA filtration and completely sealed bodies to trap allergens inside. Canister vacuums tend to perform better than uprights for removing allergens embedded in soft surfaces.

How often should I dust and vacuum?

Aim to dust furniture and vacuum carpets 2-3 times per week, especially bedrooms and most occupied rooms. Wipe down kitchen and bathroom surfaces daily if possible. Schedule deep cleanings every 1-2 months.

Should I get an air duct cleaning service?

While not always necessary, professional duct cleaning can eliminate built-up allergens, dust, and mold to provide cleaner airflow. Have them disinfect vents and change out air filters too.

How can I control pet allergens?

Keep pets off furniture and carpeted areas. Bathe them weekly to remove dander. Vacuum and dust frequently to control shed hair and skin cells. Air purifiers help remove floating pet allergens as well. Consider hypoallergenic pets.


Creating an allergy-free home may seem daunting, but taking small steps to identify and eliminate triggers can lead to big improvements in your indoor air quality and well-being. Focus on regular deep cleaning, moisture control, air circulation, and limiting fabric furnishings. With diligence and asthma-friendly upgrades, your home can become a respiratory sanctuary.
