Indoor Air Quality Solutions for Baltimore & DC

The U.S. Environmental Protection Agency estimates that the average American spends about 90% of their time indoors where the concentrations of some pollutants are often 2 to 5 times higher than typical outdoor concentrations. This means that the quality of our homes, workplaces, schools, and other buildings has the potential to impact our health, comfort, and productivity.

Are your HVAC systems being utilized to improve IAQ, or are they contributing to poor IAQ?

The Service Logic companies are ready to work with you to develop and execute the right IAQ plan for your buildings.  We do this using the latest scientific data and recommendations of accredited organizations such as ASHRAE, EPA and CDC and by asking questions such as:

System design – is your building configured and being used in the same way as originally designed?  If not, air flow in different areas is likely not matched to occupancy.  Do humidity levels get above 60%?  If so, then higher levels of pathogens are more likely.

Equipment installation – was your HVAC equipment installed correctly?  When inspecting existing systems, we often find issues such as ductwork is not sealed properly, outdoor air dampers are closed, and condensate drains are not piped correctly.

Maintenance – are your HVAC systems professionally maintained?  If not, then they are probably not operating as they were designed and they are not operating efficiently which is impacting IAQ, energy costs and comfort.

Operations – are system setpoints for heating, cooling, ventilation, humidity, and night setback optimal?  Adjustments often result in improved comfort and energy efficiency.

Filtration – are both active and passive filtration being utilized?  Very small particles such as pathogens are not carried by the air current through passive filter media and remain in the space unless active filtration such as needlepoint bipolar ionization is added.  Utilizing both technologies can also result in HEPA level filtration using MERV 10 filters.

Improve Your IAQ with NPBI Technology

GPS Air’s NPBI technology has been installed in thousands of offices, schools, airports, healthcare facilities and other community spaces around the world.

GPS is UL certified to not produce ozone and works with third-party laboratories to continually strive for best-in-class indoor air testing. Tests are conducted in large chambers designed to emulate realistic applications. To learn more about test methodology and results visit .

For schools, universities, and local/state/federal government buildings HVAC improvements and IAQ projects are eligible for considerable funding under programs such as the
