Keep Indoor Air Clean
If you forget to close your windows on high pollen days, there are steps you can take to clean the air in your house so your allergies can be kept in check. There are certain filters you can add to your air conditioning unit called HEPA filters; it automatically filters the air coming through the unit. If you have a furnace, feel free to add a flat or panel screen here to reduce allergens in the air.
Another easy tip to follow is to keep indoor air dry with a dehumidifier. You can also keep the air clean in the house if you vacuum regularly using a vacuum equipped with a HEPA filter. If regular cleaners irritate your allergies, you could also try making natural cleaners using vinegar or baking soda.
