by Quick answer: Wash all bedding weekly in hot water (130°F / 54°C or higher), vacuum the mattress surface, zip it in a dust-mite-proof protector, and keep bedroom humidity below 50%. Mites can't survive dry, frequently cleaned conditions.

Dust Mites — The Short Answer
Dust mites feed on shed skin flakes and thrive in warm, humid bedding. You can't eliminate them entirely, but you can knock the population down sharply: hot-wash bedding, vacuum, encase the mattress, lower humidity, and air it in sunlight. This matters most for allergy and asthma sufferers.
What to Do
| Step / Factor | Detail |
|---|---|
| Wash bedding hot | Launder sheets, pillowcases, and covers weekly at 130°F (54°C) or hotter. Heat kills mites that cold cycles leave alive. |
| Vacuum the mattress | Vacuum the surface with an upholstery attachment, ideally with a HEPA filter, to remove mites and the skin flakes they eat. |
| Use a mite-proof cover | Encase the mattress in a tightly woven, allergen-barrier protector. This seals mites in and keeps new ones out. |
| Lower humidity and add light | Keep humidity under 50% with a dehumidifier or AC. Mites can't survive dry air. Sunlight and fresh air also reduce them. |
Practical Tips
Skip sprays and harsh chemicals on the mattress itself — they rarely reach deep where mites live and can leave residue you sleep on. Consistency beats intensity: weekly hot washes and a sealed protector do more than any one-time deep clean. If you have allergies, washable pillows and a bare, clutter-free bedroom help too.
Our Recommendation
An old mattress holds years of skin flakes and dust deep in the layers where vacuuming can't reach. If yours is well past its prime and triggering allergies, a fresh start makes a real difference. The Saatva Classic ships with free white-glove delivery and removal of your old mattress, so the dust-laden one leaves the house entirely.

The Bottom Line
You can't fully eliminate dust mites, but hot-washing bedding, vacuuming, a sealed protector, and low humidity keep them controlled. Allergy sufferers feel the difference fastest.
Bottom line: Hot-wash bedding weekly, encase the mattress, and keep humidity under 50% to control dust mites.
