What does V.O.C. stand for? *

Volatile Organic Compound

Velocity of Circulation

Ventilation Output Coefficient

The Microcon series is effective in healthcare isolation rooms because: *

It increases CO₂ levels for patient comfort

It removes nearly all particulate matter

It uses ozone to sterilize patient spaces

A home shows strong musty odor localized to supply registers but no visible mold. The most likely root cause is: *

Potential VOCs from carpet adhesives

Biofilm development on cooling coils

Incomplete combustion from a gas furnace

PM2.5 particles pose a higher health risk than PM10 mainly because: *

They are chemically more toxic in most cases

They can enter the bloodstream

They are only produced by combustion sources

A building with consistently high VOC readings despite frequent ventilation might be experiencing: *

Inadequate particulate filtration

Off-gassing from embedded materials like subfloor adhesives

Contaminant re-entry from outdoor pollution

When selecting between HEPA filtration and a Polarized Media Filter, the latter is a better alternative because: *

It requires no mechanical airflow to operate

It can retrofit into most HVAC systems

It captures more VOCs without the need for carbon media replacements

The REME halos effectiveness with airborne microbes is most likely due to: *

Air changes per hour in the treated space

The number of pleats in the REMEs main filter

Ionization improving filtration

In HVAC applications, UV-C lights are primarily installed near cooling coils to: *

Prevent microbial growth on moist surfaces and improve heat exchange efficiency

Increase filtration efficiency for submicron particles in the airstream

Neutralize VOCs through photochemical oxidation as their main function

How polluted are modern air-tight homes compared to outdoor air? *

Typically the same as outdoors

Typically 2 to 5 times more polluted

Typically 5 to 10 times more polluted
