What Temperature Should You Wash Laundry to Kill Dust Mites and Remove Allergens?

If you or someone in your household suffers from allergies, asthma, or eczema, you may already know that dust mites are among the most common indoor triggers. These microscopic pests thrive in soft furnishings and bedding, where they feed on dead skin flakes and breed in warm, humid environments. While cleaning and vacuuming help, your washing machine is one of the most powerful tools for removing dust mites and reducing allergens, if used correctly.

Why Dust Mites Are a Problem

Dust mites aren’t visible to the naked eye but can cause significant problems for allergy sufferers. It’s not the mites that trigger allergic reactions, but their droppings and decomposing bodies. These particles become airborne and are easily inhaled, causing:

• Runny or congested nose
• Sneezing and coughing
• Itchy, watery eyes
• Asthma flare-ups
• Worsening of eczema symptoms

Since dust mites are commonly found in bedding, clothing, curtains, and upholstered furniture, regular washing is crucial for dust mite control.

The Ideal Temperature to Wash Laundry

To effectively kill dust mites and remove the allergens they leave behind, wash laundry at a minimum temperature of 60°c (140°f).

Why this specific temperature?

• It kills mites and their eggs
• It breaks down allergenic proteins found in their waste
• It removes body oils and skin flakes that mites feed on

In contrast, washing at lower temperatures—such as 30°c or 40°c—may clean dirt and odours, but it won’t reliably kill mites or remove allergens.

Can You Wash at Lower Temperatures?

Yes—but with precautions. Some fabrics, such as delicate clothing or certain linens, cannot withstand high heat. In these cases:

• Anti-allergen detergents are specially formulated to neutralise allergens, even in cooler water. Look for products labelled “hypoallergenic” or “suitable for allergy sufferers.”
• Add essential oils: Tea tree, eucalyptus, or lavender oil have mild antimicrobial properties and can enhance cleaning power.
• Run an extra rinse cycle: Helps remove detergent residue and loosened allergens.

Don’t Forget to Dry Hot

Tumble drying laundry on a high heat setting for at least 30 minutes further eliminates any remaining mites or moisture. Dryness is key, as dust mites need high humidity to survive.

If you air-dry laundry indoors, try to avoid doing so in bedrooms or living rooms. This can raise indoor humidity, making it easier for mites to thrive.

How Often Should You Wash Items?

Consistency is just as important as temperature. Here’s a practical schedule for allergy-proofing your home through laundry:

• Bed sheets & pillowcases: Once a week at 60°C
• Duvets & pillows: Every 1–2 months (or more if allergies are severe)
• Mattress & pillow protectors: Every 2 weeks
• Curtains & fabric blinds: Every 2–3 months
• Towels & bath mats: Every 3–4 days if allergy-prone

Additional Tips to Control Dust Mites

Washing is just one part of an integrated approach. For best results, combine it with:

• Using allergen-proof covers on pillows and mattresses
• Vacuuming with a HEPA filter to trap airborne particles
• Reducing indoor humidity with a dehumidifier (ideal range: 30–50%)
• Removing wall-to-wall carpeting, especially in bedrooms
• Avoiding stuffed toys or washing them regularly

Final Thoughts

Dust mites are nearly impossible to eliminate, but you can dramatically reduce their numbers and the allergens they produce with the proper habits. Washing your laundry at 60°c is a simple, science-backed way to combat these invisible intruders.
