How is AtmosAir technology different from other air purifiers?

Most HVAC air purification systems are passive. They rely on filtration, UV, or PCO technologies that only treat air once it returns to the air handling unit.

AtmosAir is proactive. It cleans the air in the occupied space, where people actually breathe, by continuously introducing controlled levels of positive and negative oxygen ions through the HVAC supply air. This means contaminants are neutralised at their source, not after they circulate through the system.

Don’t HVAC filters remove microorganisms, VOCs, and particles?

Standard HVAC filters are primarily designed to capture larger particles and are limited in their ability to remove:

• Microorganisms

• Volatile Organic Compounds (VOCs)

• Ultrafine particles

Even high-efficiency filters do not treat much of the air within the occupied space. They also do not neutralise contaminants, meaning bacteria and viruses can remain viable.

AtmosAir reduces contaminants before they accumulate or reproduce.

How is AtmosAir different from UV light systems?

UV systems are reactive technologies. They only work when air passes close enough to the UV lamp for long enough exposure.

Key differences:

• UV does not treat air in occupied spaces

• UV is ineffective against VOCs and odours

• UV requires air to return to the AHU

AtmosAir works continuously in the occupied zone. In many healthcare facilities, UV and AtmosAir are used together—UV for coil cleanliness and AtmosAir for whole-space air quality.

What is AtmosAir Bi-Polar Ionization?

AtmosAir Bi-Polar Ionization (BPI) is an indoor air purification technology that introduces controlled levels of positive and negative oxygen ions into the HVAC supply air.

These ions:

• Neutralise airborne pathogens

• Break down VOCs and odours

• Reduce fine particulate matter

The result is air quality closer to natural “fresh air” conditions—without chemicals or ozone.

Does AtmosAir replace HVAC filters?

No. AtmosAir works with mechanical filtration, not instead of it.

By causing particles to agglomerate (stick together), AtmosAir actually improves filter performance, allowing filters to capture larger, heavier particles more effectively and often extend filter life.

How does AtmosAir reduce particulate matter (PM)?

AtmosAir ions cause particles to attract each other and form larger clusters through a process called agglomeration.

These larger particles:

• Fall out of the breathing zone faster

• Are more easily captured by HVAC filters

• Reduce inhalation of ultrafine particles linked to respiratory illness

How does AtmosAir work against bacteria and viruses?

AtmosAir ions interact with the surface proteins of microorganisms, disrupting their molecular structure.

This process:

• Damages viral envelopes and spikes

• Prevents bacteria and viruses from replicating

• Renders pathogens non-infectious

This mechanism has been validated through independent laboratory testing.

How does AtmosAir reduce VOCs and odours?

Bi-polar oxygen ions surround VOC molecules and break down hydrocarbon chains, converting them into harmless by-products such as carbon dioxide and water vapour.

This makes AtmosAir particularly effective for:

• Hotels

• Hospitals

• Schools

• Casinos

• Food service and smoking environments

Does AtmosAir produce ozone?

No. AtmosAir is ozone-free.

The technology has been independently tested to:

• UL 867

• UL 2998 (Zero Ozone Certification)

AtmosAir does not produce measurable ozone in occupied spaces.

Is AtmosAir safe?

Yes. AtmosAir systems are:

• UL listed

• ENERGY STAR certified

• ANSI/AHAM tested

• Independently validated

They use no chemicals, produce no ozone, and consume very low energy.

Is AtmosAir effective in 100% outside air systems?

Yes. AtmosAir works equally well in:

• 100% outside air systems

• 100% recirculated air systems

• Mixed air systems

The ions are distributed via supply air and actively clean the occupied space regardless of air system configuration.

How is an AtmosAir system sized?

AtmosAir uses a proprietary sizing tool based on:

• Building type

• Floor area

• Occupancy

• Environmental conditions

Application engineers can also provide custom IAQP-aligned designs for complex projects.

Will I still need to change my HVAC filters?

Yes. AtmosAir does not trap particles; it neutralises them.

However, because particles agglomerate, filters often:

• Capture more effectively

• Load more evenly

• Last longer

How often do the ionization tubes need replacement?

AtmosAir composite ionization tubes should be replaced approximately every 24 months to maintain optimal performance.

Is it dangerous to touch or look at the ionization tubes?

• Touching a powered tube: Not safe. Always disconnect power before servicing.

• Looking at a powered tube: Safe. Unlike UV lamps, ionization tubes pose no eye hazard.

What temperatures can AtmosAir tubes tolerate?

Ionization tubes should not be exposed to temperatures exceeding 150°F (65°C).

Can AtmosAir help with smoke odours?

Yes. AtmosAir is widely used in:

• Casinos

• Cigar lounges

• Hospitality venues

It is highly effective at reducing smoke-related odours and airborne contaminants.

Is AtmosAir independently tested?

Yes. AtmosAir has been tested by:

• UL

• ETL

• MicroChem Laboratories

• ATL

• Other accredited laboratories

The technology is installed globally across healthcare, aviation, education, offices, and hospitality.

How do I know my AtmosAir system is working?

• Confirm the green status light is illuminated

• Adjust ion output if needed

• Replace tubes if older than 24 months

For verification, AtmosAir also offers ion level measurement devices.

What is Sick Building Syndrome (SBS)?

Sick Building Syndrome occurs when occupants experience health symptoms linked to time spent in a building without a clearly identifiable illness.

It is commonly associated with:

• Poor indoor air quality

• Inadequate ventilation

• Improper HVAC operation

Improving IAQ through proactive air purification is one of the most effective prevention strategies.
