All About
Air Filters
for Furnace
Use
A comprehensive guide to understanding
the importance, types, and selection of
air filters for home furnace systems.
Why Furnace Filters Are Essential
Filter Airborne Pollutants
Furnace filters capture allergens,
dust, and other airborne
contaminants, improving indoor air
quality.
Boost HVAC Performance
Clean filters help maintain efficient
airflow and prevent system
overworking, conserving energy.
Prevent Furnace Damage
Filters trap debris that could
otherwise accumulate and cause
expensive issues for the furnace.

Understanding the Different
Types of Furnace Filters
Electrostatic MERV Pleated
Filters
Use static electricity to effectively trap a wide
range of particles, including dust, pollen, and
pet dander. Offer excellent air purification with
a high MERV rating, perfect for homes with
allergy or asthma concerns.
HEPA Filters
Provide medical-grade air cleaning, capturing
up to 99.97% of airborne particles. Ideal for
severe allergy or asthma sufferers, but may
restrict airflow in some HVAC systems.
Fiberglass Filters
Cost-effective option that captures larger dust
and debris particles, but is less effective
against smaller airborne pollutants.
Standard Pleated Filters
Offer better particle capture than fiberglass
filters, with a higher MERV rating, but lack the
advanced features of electrostatic MERV
pleated filters.

Electrostatic MERV
Pleated Filters
(Best Overall)
Electrostatic MERV pleated filters use static electricity to
efficiently trap a wide range of airborne particles,
including dust, pollen, and pet dander. Their pleated
design increases the surface area for improved
filtration without compromising airflow, making them an
excellent choice for homes with allergy or asthma
sufferers, as well as those with pets.

Why Electrostatic MERV Pleated
Filters Are the Best Choice
Superior Energy Efficiency
Electrostatic MERV pleated filters use
static electricity to trap particles,
increasing their surface area and
improving efficiency without
compromising airflow.
Affordability and Sustainability
Electrostatic MERV pleated filters are often affordable and can be
reusable or eco-friendly, making them a cost-effective and
environmentally-conscious choice.
Prolonged HVAC System Life
The effective filtration of these filters helps protect your furnace
and HVAC system from damage caused by the buildup of debris,
extending the system's lifespan.
Comfort and Convenience
By maintaining cleaner air and reducing
the strain on your HVAC system,
electrostatic MERV pleated filters can
enhance your overall comfort and
convenience.
Improved Air Quality
These filters excel at capturing a wide
range of airborne pollutants, including
dust, pollen, and pet dander, helping to
improve indoor air quality.
