University City’s older homes often have moisture issues in ductwork or near cooling coils, making UV systems particularly valuable. They work best as a complement to particle filtration rather than a standalone solution.
MERV Ratings Explained for Philadelphia Homes
The Minimum Efficiency Reporting Value (MERV) scale ranges from 1 to 20, with higher numbers indicating better filtration. Understanding MERV ratings helps you select the right system for your University City home:
| MERV Rating | Particle Size Captured | Best Applications | Airflow Impact |
|---|---|---|---|
| MERV 8-11 | 3-10 microns | Basic residential | Minimal |
| MERV 13-16 | 0.3-1 micron | Allergy sufferers | Moderate |
| MERV 17-20 | 0.3 microns | HEPA systems | Significant |
For most University City homes, a MERV 13 filter provides excellent filtration of pollen, mold spores, and fine particulates while maintaining reasonable airflow through older HVAC systems. Homes with severe allergy sufferers might benefit from MERV 16, while basic filtration needs can be met with MERV 11.
Installation Considerations for University City Row Homes
Historic Philadelphia architecture presents unique installation challenges. Many University City row homes lack central air conditioning, requiring creative solutions for whole-home filtration. Some options include: The True Cost of Installing Central Air in an Older South Philly Rowhome.
