Avoid tracking outdoor allergens inside. Create a spot to remove shoes in the entryway. Implement a no-shoes policy and use an indoor mat to catch footwear right inside the door. Vacuum this area often during allergy season.
Remove as much clothing as you can as soon as you come inside. Jackets, scarves, sweaters, etc.
Head straight to the shower after coming inside.
Consider allergen-resistant flooring like wood and tile.
Vacuum regularly and thoroughly.
If your symptoms are bad and you can afford to redecorate, go for leather or faux leather. Pollen, dust, and dander should wipe right off. Otherwise, cover your sofa with a machine-washable slipcover and launder it weekly.
Most indoor plants don't contain the type of pollen that plagues seasonal allergy sufferers, and they may even help clean the air by absorbing volatile organic compounds (VOCs), lab studies show. That said, plants can promote mold growth and collect dust.
Use an air purifier.
You can’t get rid of all the dust in your bedroom, you can get pretty close. Start by removing decorative throw pillows and fabric curtains (since most are not washable), then pick up some dust-mite-proof encasements for your mattress and pillows. Wash your bedding once a week on the hottest setting.
Don’t open the windows. You're much better off keeping things sealed off in the bedroom, where you spend so much time, and turning on the a/c.
