No matter how clean a home is, dust mites cannot be totally eliminated.
House dust mite allergy is very common and is associated with asthma, eczema and perennial allergic rhinitis. A significant amount of exposure to house dust mite allergen happens in the bed, so taking precautions in the bedroom by using allergy-proof covers on bedding, washing it regularly can sometimes help, although clinical trials suggest that multiple measures need to be taken, possibly including the use of chemicals called acaricides, in order to see an effect. However, remember that dust mite allergen is found in all rooms of the house, on the floor and in soft furnishings, not just in the bedroom.
Measures to avoid house dust mite will lower, but do not totally remove, dust mite allergens. Often, this will be sufficient to significantly improve symptoms, but sometimes, the reduction may simply not be enough to result in a noticeable difference. There is no way to predict whether someone will benefit from avoidance measures, except by trying them. Remember that it is better to properly carry out several allergen avoidance measures in order to see an improvement in symptoms. Just doing one or two things half-heartedly may not make any difference.
“A typical mattress may have anywhere from 100,000 to 10 million mites inside. ”

I got to know about the company The Healthy Living which offers a variety of treatments like disinfection and sanitization, vacuuming, shampooing.
They provide professional services which are completely healthy for the entire family. They are very specific when it comes to cleaning and hygiene and carry the entire procedure in a systematic matter.
The Healthy Home team visited my home with two huge trolleys filled with their innovative gadgets and machine. I opted for mattress cleaning and sanitation treatment for my kids mattress since my mattress was old. Very briefly one of the team members explained me the whole process of the treatment. They helped me understand each and every single step.
They used a specialized industrial-strength pulsating vacuum device that provides extreme vibration and suction to both sides of the mattress, removing dust particles, fungal spores, and other debris.
After the removal of the waste particles, it’s time for The Healthy Home exclusive sanitation.
Step 2
Then they applied the world’s first and only medical grade mattress sanitation technology using Germicidal Ultra Violet Light (GUVL), available with The Healthy Home in the Middle East, that used powerful Ultra Violet light to destroy DNA and eliminate any remaining dust particles leaving the mattress completely sanitized. They also applied overheated dry steam technology that, unlike regular steam cleaning, heats the regular tap water into dry steam and fogs it at 180◦C to create a thermal shock that kills all Bacteria, Viruses, and Impurities and dries in less than 1 minute.

Lastly, I would really recommend this treatment from The Healthy Living to every household.
