Surprising Health Benefits of Spring-Cleaning, According to a Doctor

Keep your windows closed to keep pollen from entering your home.
Change the filters on your vacuum and AC to high-efficiency particulate air filters. This is especially helpful for those with kids and pets since it works even harder to trap harmful particles that cause allergic reactions, like pollen, pet dander, dust mites and even tobacco smoke.
Get a new mattress cover and pillow cover! If you’re allergic to dust mites, this can be especially helpful for you, since your old ones will probably have some buildup. You can even look toward hypoallergenic options or for specific kinds of covers meant to prevent allergens from affecting you.
Use disinfecting wipes to clean up areas of your house that might accumulate buildup and then go over it again with diluted white vinegar. Sometimes household products like vinegar — or even just water with a mild soap — can do a great job with cleaning, no harsh chemicals necessary.
If you have children or pets, put toys in either the freezer or the dryer — which will help to kill dust mites and other threatening allergens that could cause a reaction.
