If you've been dealing with dust mite allergies, you've probably tried everything. Sprays, covers, air purifiers, washing sheets at 60°C twice a week. And you're probably still waking up congested.
That's because most solutions only address the surface. Dust mites don't live on your sheets. They live deep inside your mattress, your pillows, and your duvet. Sprays can't reach them. Covers trap them but don't kill them. Washing your sheets helps for a night, then the colony reinfests from inside the mattress.
The one thing dust mites cannot survive is heat.
What temperature kills dust mites?
Research published in the Journal of Allergy and Clinical Immunology by McDonald and Tovey found that all mites were killed at temperatures of 55°C or greater. At 60°C, mites exposed to air died within minutes. The study also found that cold washing and detergents did not enhance killing at lower temperatures. Heat is the mechanism, not chemicals.

What is dry steam and why does it matter?
When people hear "steam" they think of humidity. Dust mites thrive in humid conditions, so it sounds counterintuitive. But dry steam is different from the wet steam you see from a kettle.
Dry steam contains less than 5% moisture. It's superheated vapour that evaporates from surfaces within seconds. It doesn't soak your mattress or create a damp environment. It delivers lethal heat deep into fabric and dries almost instantly.
This distinction matters because regular steam mops and carpet cleaners use wet steam that leaves moisture behind. Dry steam cleaners operate above 100°C with minimal water content, which means the heat penetrates deep without the dampness.
What do the studies say about dry steam and dust mites?
A study published in Clinical and Experimental Allergy by researchers at the University of Glasgow tested dry steam on carpet samples infested with dust mites. The results were clear: no live mites were found in any of the steam treated areas. In the untreated control areas, mite populations grew to 185 within four months. The study also found an 87% reduction in the primary dust mite allergen (Der p 1) in treated areas.
The researchers concluded that steam cleaning has considerable potential as a highly effective and efficient method of killing dust mites.

A separate study published in the Journal of Environmental Monitoring tested dry steam cleaning in 50 homes. The results showed that dry steam cleaning combined with vacuuming reduced dust mite allergens by 85.5%. The study confirmed that dry steam kills dust mites with high temperature vapour above 100°C, simultaneously loosening and removing allergen debris from fabrics.

Why sprays, covers, and washing aren't enough
Dust mite sprays sit on the surface. They don't penetrate deep enough to reach the colony living inside your mattress. Allergen covers create a physical barrier but the mites inside continue breeding and producing waste. Washing sheets at 60°C kills mites on the sheets but does nothing to the millions living inside the mattress itself. Within days the clean sheets are reinfested from inside.
The only method that reaches dust mites deep inside a mattress and kills them on contact is heat above 55°C delivered directly into the fabric. That's what dry steam does.
How the MiteClean System uses dry steam
The Miteva MiteClean System produces dry steam at 105°C. That's nearly double the temperature needed to kill dust mites on contact. You pass the steam cleaner slowly across your mattress, pillows, and soft furnishings. The heat penetrates deep into the fabric, killing dust mites where they actually live.
It takes minutes. No chemicals. No residue. No dampness. Just heat.
The dry steam evaporates almost instantly, meaning you're not adding humidity to your room or creating a better environment for dust mites to return. You're creating a lethal one.
Key takeaways
All mites die at temperatures above 55°C. The MiteClean System reaches 105°C.
Dry steam contains less than 5% moisture and dries within seconds.
Independent studies show dry steam eliminates 100% of live mites and reduces allergens by up to 87%.
No chemicals are involved. Just water and heat.
The method is safe for use around children, pets, and people with sensitive skin.
