Allergies can be frustrating, especially when pollen, dust, pet dander, mold spores, and other irritants make their way indoors. While no single step can remove every allergen from home, a few regular habits can help improve indoor air quality and make your living space more comfortable.

Change Furnace Filters Regularly

The furnace air filter plays an important role in trapping dust and airborne particles before air circulates through the home. Air circulates through this filter when both the furnace (heating) and air conditioner are running (if the property has central air). 

A good rule of thumb is to check it monthly and replace it when it looks dirty, especially during heavy heating or cooling seasons.

When replacing a filter, make sure it is the correct size and installed in the proper direction.  The filter will be located next to your furnace and either slide out from the top or side.  See below video on changing furnace filters.

Clean Window Air Conditioner Filters

Window and wall air conditioning units have removable filters that collect dust and debris.  Usually, the front cover folds down allowing access to the filter, in some AC units the filter slides out the side.  A dirty filter can reduce airflow causing the unit to be less effective and may recirculate allergens back into the room.

During the cooling season, remove and clean the filter regularly. Gently vacuum and/or rinse it in the sink with warm soapy water, then allowed to dry completely before being placed back in the unit.  Never operate a window air conditioner without its filter in place. If the filter is damaged, missing notify the landlord.

Consider Using an Air Purifier

A portable air purifier can be helpful in rooms where you spend the most time, such as a bedroom or living room. Look for a unit that is designed for the size of the room and uses a HEPA filter or clearly states that it captures fine airborne particles. For best results, keep doors and windows closed while the air purifier is running and replace the purifier filter as recommended by the manufacturer.

Keep Allergens from Building Up

• Dust surfaces regularly with a damp cloth so dust is captured instead of pushed into the air.
• Vacuum carpets and rugs frequently, especially in high-traffic areas.
• Wash bedding often, particularly pillowcases and blankets.
• Keep windows closed when pollen counts are high or outdoor air quality is poor.
• Use bathroom and kitchen exhaust fans to reduce moisture that can contribute to mold growth.
• Report leaks, visible mold, or persistent moisture problems to your landlord promptly.
