This spring is shaping up to be one of the longest allergy seasons. Experts say warmer temperatures and an earlier spring are extending pollen exposure across the county — and Oregon is no exception.

Fortunately, there are some things you can do at home that can keep some of the allergens out and help you save energy at the same time.

Here are five easy, low- and no-cost ways to clean the air in your home:

Check your air filter often
A standard heating and cooling system filter typically last a few months, but during high pollen or wildfire smoke periods, they can get dirtier, faster, meaning your system must work harder and use more energy. During allergy season, check your filter every two to three weeks and replace it if it looks dirty. Minimum Efficiency Reporting Value (MERV) filters are rated based on their efficiency in trapping airborne particles like dust and pollen, ranging from basic filtration on the lower end to specialized filtration on the higher end. Higher-rated MERV filters capture more particles, but they can restrict airflow and make your system work harder — so check your manufacturer’s recommendations.

Use “fan only” mode
Running your system in “fan only” mode can help continuously circulate air through the filter without activating heating or cooling. This can improve air distribution and filtration while using less energy than a full system cycle.

Seal windows, doors and A/C units
Keep allergens from “leaking” into your living space by sealing gaps around window A/C units, doors and window frames. Installing fresh weatherstripping or closing outdoor air dampers act as a physical barrier against outdoor allergens. In addition to improving indoor air quality, sealing air leaks can reduce heating and cooling losses, lowering your energy bills.

Avoid adding indoor air pollution 
During allergy season, avoid using incense, candles and aerosol sprays, and opt for cooking methods other than high-heat frying or broiling. Once pollen counts drop, use your heating and cooling system’s fresh air intake or open windows to ventilate your home.

Consider an energy-efficient air purifier
Portable air purifiers can help remove pollen, dust and pet dander. Keep an eye out for models equipped with high-efficiency particulate air (HEPA) filters, which are some of the most effective at trapping allergens. Energy Trust offers an instant $75 discount on ENERGY STAR high-efficiency air purifiers. These models can be ordered online with free shipping or can be found on this list at a store near you.

By taking small steps, you can breathe easier during this longer allergy season, while saving with lower energy bills.
