True story: Khun Ratthakan Phornsiri — Single-family home, family of 4, Bang Yai

King mattress 10 years old, L-shape fabric sofa 7 years old. Kids 6 and 9 started waking up with sneezing and itchy nose. Skin prick test came back Class-4 dust mite positive. Doctor said dust mites had to come down fast. Replacement cost would be 50K+ THB.

The Daily Pain

• Mattress/sofa absorbed sweat, saliva, fur for 10 years
• Class-4 dust mite allergy in the children
• Musty smell mainly at night
• New ones cost 50K+ THB
• Cover washing isn't enough
• Vacuum only reaches the top layer

Why Normal Fixes Fail

Dust-mite vacuums reach the top 0.5 cm — but mattresses are 25 cm thick with mites deep inside. Mite sprays don't penetrate fibers. L-shape sofas can't be fully washed. Sunning every 3 months doesn't kill mites at the core. Ozone gas penetrates every fiber, killing mites and mold spores together.

Surface fixes are like adding sugar to a glass of poisoned water — looks better, but the problem remains. The real fix destroys odor molecules and germs at the deep level.

The Solution: WHD Residential Ozone Disinfection

WHD uses a portable 10,000 mg/h ozone generator — a small black box-shaped unit with a top handle, LED display, red control buttons, and side ventilation grilles. Placed on a bed, sofa, or center of the room, it releases high-concentration ozone filling the entire space.

This is the same service that hospitals, 5-star hotels, and major real-estate projects use to reset rooms between guests/patients at 99.99% cleanliness.

10 Reasons to Choose WHD Residential Ozone Disinfection

1. Ozone up to 10,000 mg/h

Industrial-grade concentration filling a 60-200 sqm home, penetrating furniture, curtains, mattresses, sofas where odor and germs hide.

2. Kills 99.99% of viruses, bacteria, fungi

Ozone is 3,000x stronger than chlorine. It destroys COVID-19, Influenza, Norovirus, RSV, MRSA, E.coli, Salmonella, Aspergillus, Black Mold in one step.

3. Destroys odor molecules — doesn't mask them

Ozone breaks down VOC, formaldehyde, oil, nicotine, ammonia (pet urine) at the molecular level — small odorless molecules. Problem ends.

4. No chemical residue, no furniture damage

After 30 minutes, ozone decays to oxygen (O₂) naturally. No toxic residue, no corrosion of furniture, fabric, metal, or electronics.

5. Reaches where wipes can't

Inside walls, cracks, behind cabinets, under beds, in AC systems — ozone is a gas, going wherever air goes. Wipes only reach smooth surfaces.

6. Safe for pets, elderly, children after service

During service, people/pets/plants/food leave for 4-8 hours. After 30 min ventilation, ozone decays to oxygen — everyone returns safely.

7. One-time treatment — no more endless sprays

Monthly sprays cost 1-3K THB; daily ozone rentals not worth it. WHD's one-time service includes equipment, technician, time — safe and complete in 1 day.

8. Trained Ozone Safety technicians

WHD's team sets duration, concentration, and placement based on room size and materials — safer than DIY.

9. Result guarantee — we redo it if not solved

If problems remain after service, WHD returns and redoes the treatment at no extra cost.

10. Works on every space

Homes, condos, cars, walk-in closets, shoe cabinets, storage rooms — the portable unit scales 10-200 sqm.

Before VS After

Before: Kids Class-4 dust mite allergy, waking with cough and itchy nose, family sleeping poorly, 50K+ THB replacement looming

After: Dust mites down 99.99%, kids stopped coughing, no itchy nose, kept existing mattress/sofa, saved 50K THB

Real User Testimonial

"Doctor said I had to replace the whole mattress set for 50K. I chose WHD instead. Team worked 6 hours, killed dust mites in every fiber. Within a week my kids stopped coughing at night. Next skin prick test dropped from Class 4 to Class 1. Tears in my eyes."
