- Keep your windows closed! (duh) Even though it's gorgeous outside the little unseen pollen predators are just waiting for you to open a door or a window and in they fly! If you absolutely can't live without some fresh air in your home, use a window screen filter to let the pollen-free breeze in.
- Avoid yardwork like mowing the lawn or raking leaves, which stir up even more allergens than are already airborne. If you cannot avoid yardwork, wear a pollen mask. (from National Allergy)
- Don't turn on your attic fan.
- Replace your furnace filters or wash electrostatic filters regularly to help clean pollen out of the air. You can also use vent filters on the room vents to catch anything that might have made it by the furnace filter or pollen and other allergens that may have already settled in your air ducts.

- The room you likely spend the MOST time in is your bedroom, so take special care to ensure that the air you breathe as you're sleeping is pollen free. (you will wake up with much fewer symptoms!) Use a HEPA air cleaner in this room during the night.
- Take your shoes off when you come inside. If you're especially bothered by pollen, you would be well served to change your clothes after spending significant time outdoors.
- After a walk or outside play, wipe down your pet's fur before entering the home. Animals hold A LOT of pollen in their coats. If they sleep in your bedroom and have been outside a lot that day, you might consider bathing them before bed.
- Dust. Keeping your home clean will help reduce the amount of bothersome allergens including pollen. But be aware that dusting can actually make things worse by kicking up allergen particles into the air. Use a damp or treated cloth that attracts dust rather than scattering it, and consider wearing a dust mask when cleaning. Also, try to minimize clutter in your home, since it tends to collect dust.
