Office and Meeting Room Air Purification with Ozone Purifier & Negative Ion Generator
Better air = better productivity, fewer sick days, energized team.
Napaporn's story — HR Manager at an 80-person Thai tech firm
Napaporn, HR Manager at a Thai tech company with 80 staff, open-plan office in Asoke. She saw a high sick-leave rate at 2.3 days/person/month, peaking in monsoon and flu seasons. Sales team complained that after big meetings the conference room felt stuffy. Net effect: team productivity dipped.
She installed multiple HEPA air purifiers — filtered dust but didn't kill pathogens or remove smell. The CIO recommended Ozone Purifier + Negative Ion Generator from WHD — purification + pathogen reduction + negative ions for mood, all in one.
After 6 months with 3 units, sick leave fell to 1.4 days/person/month — saving hundreds of thousands per year.
Why office air matters for productivity
- Harvard 2015 study — 8% productivity gain in clean-air rooms
- CO₂ levels — over 1,000 ppm causes drowsiness, focus loss
- PM2.5 — high urban levels cause headaches, eye irritation
- Pathogens — influenza, RSV, COVID spread in enclosed rooms
- VOCs from new furniture — formaldehyde
- Negative ions — in nature (rain, forest, sea) improve mood and reduce stress
Cost of poor office air
- Sick leave 2.3 days/person/month × 80 people × THB 1,500/day = THB 276,000/month
- Productivity drop of 8% of total payroll
- Team turnover, HR replacement costs
- Underused meeting rooms because guests complain about stuffiness
How Ozone Purifier + Negative Ion Generator works
Unlike Master Ozone Generator (used for shock-treatment of empty rooms), Ozone Purifier is designed for occupied use:
- Releases low-concentration ozone continuously — safe with people present
- Emits negative ions — bind PM2.5 dust, dropping it to floor
- HEPA + carbon filters — capture dust and VOC gases
- Kills airborne pathogens — viruses and bacteria at low levels
- Removes mild odors — low-level ozone oxidizes light molecules
10 reasons offices need Ozone Purifier + Negative Ion Generator
1) Lower sick-leave rate — clear ROI
Sick leave drops 30–50% in 6 months.
2) Higher team productivity
Cleaner air, sharper focus — 8% productivity uplift.
3) Lowers indoor PM2.5
Especially valuable in Bangkok and Chiang Mai haze seasons.
4) Continuous airborne pathogen reduction
Runs all day, no cycling.
5) Negative ions improve mood
Team feels fresh, like by a waterfall.
6) One unit covers 30–60 sqm
Open-plan offices use 2–4 units depending on size.
7) Very quiet — knowledge-work friendly
Doesn't disrupt meetings or calls.
8) Use in meeting rooms hosting workshops or VIP clients
Odor and pathogens cleared in an hour.
9) ESG / wellbeing story for the company
Tool for attracting and retaining employees.
10) WHD consults on the right number of units
Installation, maintenance, filter replacement.
