Odour Solutions — UV-C / Ozone / Plasma

UV-C, Ozone & Plasma Air Purification

Advanced air purification solutions for waste management areas. UV ozone, plasma and filtration technologies keep waste disposal areas clean, fresh and hygienic — eliminating odours and airborne contaminants at source.

Downwaste plasma air purification unit

Overview

Three technologies. One clean building.

Ensuring garbage room disinfection and maintaining waste room odour control are essential for health, safety and overall well-being. Our advanced odour neutralisation systems use UV-C, ozone, plasma and filtration technologies to keep waste disposal areas clean, fresh and hygienic — addressing not just odours but bacteria, viruses and airborne particulates.

Product range

Three units for every area

Unit 1

Cleanair Sky Units

Ceiling-mounted in waste rooms and garbage areas

Multi-stage filtration using plasma and activated charcoal filters to remove dust, odours and airborne contaminants. Handles spaces up to 40 m² and provides continuous air purification — ideal for garbage rooms and large waste storage areas.

  • Plasma and activated charcoal filtration
  • Covers up to 40 m²
  • Removes dust, bacteria and malodorous compounds
  • Ceiling mount — minimal footprint

Unit 2

Freshair Units

Wall or duct mounted in waste disposal areas

Freshair units combine UV-C and ozone injection technology to eliminate odours and germs in waste disposal areas. The ozone injection is particularly effective at neutralising waste chute odours, while UV-C provides continuous disinfection of passing air.

  • UV-C germicidal irradiation
  • Ozone injection for chute odour neutralisation
  • Wall or duct mount options
  • Suitable for large waste disposal areas

Unit 3

Plasma Mini for Waste Chutes

Mounted inside or at the base of the waste chute

A compact plasma unit specifically engineered for waste chute hygiene. The Plasma Mini injects plasma ions into the chute shaft, neutralising odours and bacteria at source — stopping smells before they reach resident floors. Low power, minimal maintenance, maximum impact.

  • Plasma ion injection inside the chute shaft
  • Neutralises odours and bacteria at source
  • Compact form — fits inside standard chute
  • Low power consumption

Features

Why specify UV-C / ozone / plasma?

Eliminates rather than masks odours

UV-C, ozone and plasma technologies actively destroy the molecules responsible for malodours at a molecular level — rather than simply masking them with fragrance. The result is genuinely clean air.

Kills airborne bacteria and pathogens

UV-C irradiation is highly effective at destroying airborne bacteria, viruses and mould spores. This is particularly valuable in waste rooms and chute areas where hygiene standards must be maintained.

Three complementary technologies

Cleanair Sky units (plasma + activated charcoal), Freshair units (UV-C + ozone) and Plasma Mini (plasma injection) each address different odour and contamination challenges — allowing a tailored solution for every area.

Treats the chute at source

The Plasma Mini unit is specifically designed to be installed inside the chute shaft itself — neutralising odours and bacteria before they can travel up to resident floors or escape through chute doors.

Supports building health credentials

Continuous air purification in waste areas contributes to overall building indoor air quality — supporting WELL Building Standard, BREEAM and similar certifications that assess air quality and occupant health.

Low maintenance, long service life

All three unit types are designed for minimal routine maintenance. UV-C lamps and filter elements require periodic replacement — typically annually — with no specialist skills required.

FAQ

Common questions

What are UV-C, ozone and plasma air purification systems?

These are three distinct but complementary technologies used to purify air in waste management areas. UV-C (ultraviolet-C) light destroys bacteria and viruses by disrupting their DNA. Ozone injection neutralises malodorous compounds through oxidation. Plasma technology generates reactive ions that destroy pollutants, odours and pathogens in the air.

What are the benefits of Cleanair Sky units in waste management areas?

Cleanair Sky units efficiently handle garbage room disinfection by removing dust, odours and airborne contaminants. Their multi-stage filtration system — which includes plasma and activated charcoal filters — ensures effective waste room air purification, neutralising bacteria and improving air quality in waste areas up to 40 m².

How do Freshair units eliminate odours and germs?

Freshair units combine UV-C germicidal irradiation with ozone injection. The UV-C component continuously disinfects passing air, while ozone injection neutralises malodorous compounds from waste. Together they provide highly effective odour and pathogen control in waste disposal areas.

What is the role of the Plasma Mini in waste chute hygiene?

The Plasma Mini is specifically designed for installation inside or at the base of a waste chute. It injects plasma ions into the chute shaft, neutralising odours and bacteria at their source — before they can travel upward to resident floors or escape through chute intake doors.

Why is ozone injection important for waste chute disinfection?

Ozone is a powerful oxidising agent that reacts with and destroys the organic compounds responsible for waste-related odours. When injected into a waste chute, it neutralises smells throughout the chute shaft — providing a level of odour control that fragrance alone cannot achieve.

Can these units be installed in existing buildings?

Yes. All three unit types can be retrofitted into existing waste rooms and chutes. Cleanair Sky and Freshair units require only a standard electrical connection. Plasma Mini installation inside a chute may require a brief period of access to the chute shaft.

Are the systems easy to maintain?

Yes. UV-C lamp replacement is typically required annually, and activated charcoal filter cartridges in Cleanair Sky units are replaced at service intervals. The Plasma Mini requires minimal maintenance beyond annual inspection. All servicing can be carried out by a building maintenance team with appropriate training.
