The basics
Better air balances four things: capturing particles, controlling humidity, bringing in fresh air, and reducing growth on the coil.
- Filtration (MERV): Higher MERV captures smaller particles, but too-high MERV chokes airflow — it must match your system.
- Humidity: Houston's humidity drives comfort and mold risk; a right-sized AC removes some, a whole-home dehumidifier handles the rest.
- Ventilation (ERV/HRV): Brings in fresh air without dumping your conditioned air.
- UV germicidal light: Reduces microbial growth on the coil — not a particle filter.

Your options
IAQ options compared — match the fix to the symptom.
Filter / media filter
Lowest cost; pick the right MERV (trade-off: airflow vs. capture).
HEPA / advanced filtration
Highest particle capture; needs a compatible setup.
UV germicidal lights
Target microbial growth on the coil.
Whole-home dehumidifier
The high-impact upgrade for Houston comfort and mold control.
ERV/HRV ventilation
Fresh air with energy recovery; best for tight homes.
Honest trade-off: no single device does everything — the right mix depends on your symptoms, home, and system.

- Will this actually help my allergies?
- We diagnose the cause — particles vs. humidity vs. ventilation — before recommending anything.
- Do I need the expensive system?
- Often a filter + humidity fix does most of the work; we recommend the smallest effective solution.
