True story: Khun Wipawan & Khun Weerachai — Resort-style house, Pathum Thani

Khun Weerachai's jacuzzi bathtub has run nightly for 5 years. Last month he developed itchy red rashes on his back and neck, and Khun Wipawan got a respiratory infection. The doctor suspected Pseudomonas and Legionella from the tub plumbing. Black grime under the tub edge, musty bathroom smell, mold starting on the ceiling.

The Risks

• Hot tub folliculitis from Pseudomonas
• Legionnaire's pneumonia from Legionella
• Black mold in grout and rubber seals
• Musty smell in towels and shower curtains
• Surface cleaners don't reach pipes

Why Normal Fixes Fail

Surface scrubbing doesn't kill germs in plumbing. Pseudomonas and Legionella live in biofilm inside pipes. Concentrated chlorine corrodes tub rubber. Spray disinfectants don't reach cracks under the tub or ceiling cavity.

Solution: WHD Ozone Reset

WHD places a 10,000 mg/h portable ozone unit in the master bathroom for 6 hours. As a gas, ozone seeps into pipes, ceiling voids, and under-tub cracks — killing Pseudomonas, Legionella, and mold 99.99%. Decays to oxygen, no corrosion of the jacuzzi.

10 Reasons WHD Kills Pseudomonas/Legionella

1. 10,000 mg/h ozone penetrates plumbing as gas
2. Destroys biofilm where Pseudomonas/Legionella live
3. Kills 99.99% Pseudomonas, Legionella, Aspergillus, Black Mold
4. No corrosion on tub rubber, plastic, marble
5. Reaches ceiling voids and under-tub cracks
6. Removes musty odor and mold spores
7. Zero residue — decays to O₂
8. Safe for adults/kids after 30 min ventilation
9. Guaranteed — redo free if germs return
10. Faster than full system replumbing

Before VS After

Before: Hot Tub Folliculitis rashes, respiratory infection
After: Pseudomonas/Legionella gone 99.99%, jacuzzi safe again
