How the Best Air Filters Work to Keep You Allergy-Free

How the Best Air Filters Work to Keep You Allergy-Free, updated 2/28/25, 9:45 AM

The best air filters, such as HEPA and electrostatic MERV pleated filters, effectively trap allergens like dust, pollen, and pet dander. These filters use advanced technology to capture particles as small as 0.3 microns, preventing allergens from circulating in your home's air. Regularly replacing air filters enhances HVAC efficiency, improves indoor air quality, and helps reduce allergy symptoms by maintaining a cleaner, healthier living environment.

Understanding MERV Ratings
What is MERV?
MERV stands for Minimum
Efficiency Reporting
Value, a standard that
measures an air filter's
ability to capture
airborne particles.
Importance for
Allergies
Higher MERV ratings (8 or
above) indicate a filter's
ability to capture smaller
allergens like pollen, dust
mites, and pet dander.
HVAC System
Compatibility
When choosing a MERV-
rated filter, ensure it
matches the airflow
requirements of your
HVAC system to avoid
restricting airflow.
MERV Rating Scale
The MERV scale ranges
from 1-20, with higher
numbers capturing
smaller particles more
effectively.

The Power of
HEPA Filters
High-Efficiency Particulate Air (HEPA) filters
are renowned for their exceptional ability to
capture 99.97% of allergens as small as 0.3
microns. This unparalleled filtration efficiency
provides superior air purification, making
HEPA filters a crucial ally in the fight against
airborne allergens.

Maintaining Air Filters for
Optimal Performance
Change air filters every 1-3 months, or as recommended
by the manufacturer, to ensure continuous allergen
removal and optimal HVAC performance.
Select air filters with a MERV rating of 8 or higher to
effectively capture small airborne particles that trigger
allergies, such as pollen, dust mites, and pet dander.
Regular HVAC maintenance, including cleaning air ducts,
vents, and registers, helps minimize the circulation of
allergens throughout your home.
Replace Filters Regularly
Choose the Right Filter
Maintain HVAC System
Use a humidifier or dehumidifier to maintain indoor
relative humidity between 30-50%, which can inhibit the
growth of mold and dust mites.
Check air filters periodically for signs of clogging or
reduced airflow, and replace them as needed to ensure
optimal air purification.
