High-Efficiency Particulate Air (HEPA) Filtration

Certified HEPA media captures 99.97% of particles at 0.3 microns. HEP integrates inline HEPA canisters or standalone filtration units that tie directly into ductwork, creating a hospital-grade cleanroom effect without drastic modifications.

Energy Recovery Ventilators (ERV) and Heat Recovery Ventilators (HRV)

ERVs and HRVs exchange heat and, in the case of ERVs, moisture between incoming and outgoing air streams. These devices allow fresh air to enter while recovering up to 80% of the energy typically lost in the ventilation process. Fayetteville properties benefit by reducing both cooling and heating loads.

UV-C Germicidal Lights

Mounted within the air handler or supply plenum, UV-C lamps disrupt the DNA of microorganisms, rendering them incapable of reproduction. HEP selects lamps with the correct wavelength and intensity to continuously sanitize passing air without producing harmful ozone.

Smart Thermostats and Connected Controls

Modern thermostats featuring Wi-Fi connectivity, occupancy sensors, and multi-stage control algorithms give HEP specialists the ability to fine-tune system operation. Remote analytics provide real-time feedback on energy usage and IAQ metrics.

Ventilation Challenges Specific to Fayetteville Climate
