Elevate Your Comfort with Our Expertise
Most homes use basic filters that do not capture:
Fine dust (PM2.5)
Pollen
Pet dander
Smoke particles
Medical-grade protection requires higher-efficiency filtration, properly matched to the HVAC system.
Humidity levels directly affect airway health.
Too dry (<30%) → dry airways, irritation, increased infection risk
Too humid (>60%) → mold growth, dust mites, worsened asthma
Balanced humidity helps protect the lungs and sinuses.
Modern homes are often tightly sealed, which can trap:
CO₂
VOCs (from cleaners, furniture, building materials)
Bacteria and viruses
Proper ventilation systems help remove contaminated air and bring in fresh air safely.
Dirty ducts, coils, and components can circulate:
Mold spores
Dust buildup
Bacteria
Clean, properly designed airflow reduces respiratory stress.
