Continuous Odour Control at the Molecular Level — Design for 24/7 Operation
Cold Plasma / NTP technology breaks down odour molecules, reduces airborne microorganisms, and helps prevent bacterial build-up — ideal for Pet Hotels, Senior Care facilities, schools, central kitchens, and Wellness Centres — chemical-free, with no odour masking, and designed for continuous 24-hour operation in occupied spaces.
— The 2S Principle —
Every Odor Has a Different Origin — We Match the Method to the Source
A common mistake is applying the same approach to all types of odor. “Airborne odor” and “heavy odor from organic sources (grease traps, drains, waste)” require fundamentally different solutions. That’s why 2S uses two complementary technologies — always matched to the specific site.
Air-side
Cold Plasma — continuously eliminates airborne odor 24/7. Suitable for: patient wards, elderly care rooms, animal enclosures, production areas, lobbies.
✓ Breaks down odor molecules floating in the air — continuously
✓ Simultaneously reduces airborne pathogens
✓ Installs in existing HVAC ducts or as a stand-alone unit — no system overhaul required
Source-side
Bio-enzyme microbial treatment — digests heavy odor at the origin. Suitable for: grease traps, drain pipes, waste holding points, floor drains.
✓ Eliminates heavy odor at the source — not just masking it in the air
✓ Non-toxic, biodegradable — safe to use while people/animals are present
✓ Applied continuously on a dosing schedule — works in tandem with Cold Plasma on the air side
“Masking Odours” and “Breaking Down Odours” Deliver Different Long-Term Results
Why Choose Cold Plasma NTP?
| Fragrance / Air Freshener Spray Works by "masking" odor | 2S Technical Odor Control System Works by "molecular breakdown + source elimination" | |
|---|---|---|
| Long-term Result | ✗Odor returns when the product wears off — requires constant reapplication | ✓Helps break down odour-causing molecules rather than temporarily masking the smell |
| Pathogen Control | ✗Does not address pathogens or the root cause of odor | ✓Simultaneously reduces airborne pathogens alongside odor |
| Long-term Cost | ✗Ongoing cost with no end — must keep repurchasing indefinitely | ✓Continuous operation with predictable, plannable cost structure |
⚠️ Results may vary depending on the size of the space, airflow volume, and system design. 2S provides a free assessment before every installation.

How We Work with You at 2S
Site Assessment
Identify whether the odour originates from the air or from organic sources such as grease traps, drains, or waste, while assessing the existing air system.
Match the Right Technology
Select Cold Plasma for airborne odours, bio-based microorganisms and enzymes for odour sources, or combine both — based on site conditions and budget.
Measure Results + Ongoing Care
Conduct before-and-after testing, supported by a maintenance plan and a clear assessment of total lifecycle costs.

How Does Cold Plasma Compare with Other Odour Control Methods?
| Comparison | Cold Plasma (2S) | Odour Sprays / Deodorisers | Ozone Shock Treatment |
|---|---|---|---|
| Operation Around People / Pets | ✅ Continuous 24/7 operation at safe levels | ✅ Yes, but provides only temporary odour masking | ❌ People and pets must leave the area before treatment |
| Reduction of Airborne Microorganisms | ✅ Reduces airborne microorganisms while treating odours | ❌ No | ✅ Only while the system is operating and the area is unoccupied |
| Odour Treatment Method | Breaks down odour molecules at the source | Masks odours with fragrance; odours return once the effect wears off | Uses strong oxidation as an intermittent treatment rather than continuous operation |
| Safety | Designed to operate at safe levels while people and pets are present | Depends on the chemicals used in the product | Requires strict control and must be used in enclosed, unoccupied areas |
| Long-Term Cost | Cost-effective, with periodic lamp replacement required | Ongoing recurring cost due to continuous product replenishment | Higher electricity and maintenance costs, with operation limited to specific periods |

— Frequently Asked Questions —
Frequently Asked Questions About Odour Control
What is the difference between odour-masking sprays and an odour elimination system?
Sprays and air fresheners temporarily mask odours, so the smell returns once their effect wears off. Technical odour control systems, by contrast, are designed to break down odour-causing molecules while also reducing airborne microorganisms. This addresses the source of the problem, enables continuous operation, and provides more predictable long-term operating costs.
Is the odour control system safe for people and animals in the area?
For airborne odours, 2S uses Cold Plasma / bipolar ionization technology designed to operate continuously, 24/7, at safe operating levels. For severe odours originating at the source, 2S uses non-toxic, biodegradable biological microorganisms and enzymes that can be applied while people and animals are present.
Can the system treat odours originating deep inside pipes, grease traps, or waste areas?
Yes. Cold Plasma helps reduce airborne odours, while severe odours originating from organic sources are treated with biological microorganisms and enzymes that break down the organic matter responsible for the odour. This addresses the problem at its source rather than simply masking the smell in the air.
Do we need to replace or modify the building’s existing air-conditioning system?
No. The system can be retrofitted into existing air ducts, installed at coils, or deployed as a stand-alone unit in specific areas. It can work alongside the building’s existing HVAC and filtration systems without requiring a complete system replacement.
Are there ongoing maintenance costs?
Yes. As with any engineered air treatment system, periodic maintenance and component replacement are required depending on usage. The 2S engineering team provides a clear Total Cost of Ownership (TCO) assessment before installation, helping you understand and plan for costs throughout the system’s lifecycle.
Can the system remove odours deeply absorbed into carpets and walls?
Continuous Cold Plasma operation can help reduce airborne odours. For odours that have been absorbed into carpets, fabrics, or walls over a long period, it may take approximately 2–4 weeks for accumulated odours to noticeably diminish. In some cases, deep cleaning may also be recommended alongside the system.
Is a stand-alone system suitable for a small pet hotel?
Yes. For spaces of approximately 50–200 sq.m., one or two stand-alone units may typically provide suitable coverage, depending on the site conditions. There is no need to dismantle or modify the existing air-conditioning system, and the units can be repositioned as operational needs change.
Can the system help reduce diaper, wound, and urine odours in senior care facilities?
Yes. These odours can disperse through the air, and a continuously operating Cold Plasma system can help reduce odour accumulation and dispersion in resident rooms and common areas. However, the system is not a substitute for proper hygiene practices, wound care, or scheduled diaper changes.
