1. Close the Windows
Keep your windows closed to help keep allergens on the outside. If it gets warm, use an air-conditioner.
2. Hot Wash, Hot Dry
Once a week, wash bedding in hot water and dry it in a hot dryer.
3. Filter Your Air
Consider using a HEPA (high-efficiency particulate air) filter wherever you spend a lot of time, especially your bedroom.
4. Keep Pets Off the Bed
Keep your pets out of your bedroom and especially off your bed to help reduce their allergic effects.
