These microscopic bugs can trigger allergies and asthma. They can often be found living in your bedding.
You can take some steps to get rid of them:
Put dust-mite-proof covers on pillows, comforters, mattresses, and box springs.
Wash your blankets, sheets, and pillowcases every week in water that is at least 130 F. Dry everything in a hot dryer.
2. Vacuum Regularly
Carpet is a popular place for dust mites. Consider replacing it in your bedroom with hardwood floors or linoleum and washable area rugs.
If you must have carpet in your bedroom:
Choose the low-nap or low-pile kind, which holds fewer allergens.
Clean it using a vacuum with a HEPA filter and a double bag every week. Wear a dust mask while you vacuum so you don’t inhale dust that floats up into the air.
3. Use Light and Breezy Window Treatments
Say goodbye to dust catchers like blinds and heavy, dry-clean-only drapes. Try washable curtains and roller shades, instead.
Wipe window frames and glass regularly to prevent mold and mildew. Both can trigger upper respiratory symptoms if you have allergies or asthma.
4. Declutter Your Bedroom
Keep things simple to breathe better. Cut back on knickknacks and fabric. The less upholstery in the room, the better.
Move books, magazines, and decorative items to another room, so you can dust less often.
Don’t store things under your bed.
5. Protect Bedroom Air
Dust mites and mold like a warm, damp room, but you probably don't.
When it's warm, use your air conditioner, even if you’re tempted by the outdoor breeze.
If you live in a sweaty-weather climate, use a dehumidifier to keep humidity at 30% to 50%.
Turn down the heat or turn up the AC. Dust mites can’t breed as well at temperatures below 77 F.
You may want to try an air-filtration system that uses a small-particle or HEPA filter to keep the air in your bedroom cleaner. These filters work in central air conditioning and heating systems and in portable AC units.
