True story: Khun Supat Thanakorn and family of 5 — 2-story house, 200 sqm, Nonthaburi

Eight months after moving in, everyone developed chronic coughs, headaches, and red rashes. Their 2-year-old saw the doctor twice a month. Diagnosis: Sick Building Syndrome. Cause: mold in the AC and formaldehyde from new furniture. His wife was losing income to sick-child leave.

The Daily Pain

• Doctor bills 6-8K THB/month for the whole family
• 2-year-old now on Salbutamol for wheezing
• Poor sleep, morning congestion, headaches
• Wife losing income on sick-child leave
• Dream new home turned into an ER waiting room
• 30K THB air purifier didn't help

Why Normal Fixes Fail

Air purifiers only filter airborne dust — they don't destroy mold spores in walls. Floor mopping only cleans surfaces. VOCs from new furniture keep off-gassing for 2-3 years. Opening windows isn't enough because formaldehyde is heavier than air and settles on the floor and carpet.

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: Family chronically ill 8 months, 8K+ THB/month doctor bills, 2-year-old on Salbutamol, wife on sick-child leave, 30K THB air purifier useless

After: Within 2 weeks: family stopped coughing, rashes faded, son no longer wheezing, sleep improved, doctor bills down 80%. The new home finally felt like home.

Real User Testimonial

"I almost can't believe it. My son who wheezed every night for 8 months — within 2 weeks after the 6-hour ozone treatment, completely gone. My wife stopped coughing. My headaches stopped. This is the real fix I needed for my family. Worth every baht."
