Frequently Asked Questions
HVAC Lifespan
Regular filter replacement reduces strain on HVAC parts, prevents dust
and debris buildup, and stops overheating, extending the lifespan of
your HVAC system.
Health Benefits
The EPA says that higher-efficiency filters
reduce allergens and irritants, improving
indoor air quality and health.
Filtration Efficiency
Fiberglass filters typically rate between
MERV 1–4, capturing only large particles.
Electrostatic filters often rate MERV 8 and
higher, trapping smaller particles like pollen,
pet dander, and smoke. The EPA confirms
that low-MERV filters don't remove fine
particles effectively.
Fiberglass vs. Pleated Filters
Fiberglass filters have low upfront cost but need frequent
replacements, poor particle capture, and lead to faster dust buildup in
HVAC systems. Pleated filters offer cleaner air, better efficiency, fewer
replacements, and real results in reducing allergy symptoms and
HVAC wear.
Energy Efficiency
The GSA reports that upgrading to MERV 13
filters can increase fan energy use by 11–18%,
making high-efficiency filters a more
energy-conscious choice.
