Filter basics
Airflow vs pleated filters
Every filter trades some airflow for particle capture. Here is how fiberglass, pleated disposables and EverFilter compare, so you can pick the right balance for your system.
How EverFilter Compares to Traditional Filter Types
Low-MERV Fiberglass Filters
MERV 1-4 · Minimal resistance, limited protection
- Captures large debris like lint and visible dust
- Very low airflow resistance when clean
- Minimal particle capture beyond large contaminants
- Media collapses easily under higher airflow
- Offers little system or indoor air protection
- Short service life and frequent replacement
Lowest upfront cost, lowest performance
Best for: Basic protection only where airflow is the sole priority
Recommended
EverFilter Reusable Frame & MERV-8 Air Filter Media
Balanced airflow and reusable filtration for long-term system protection
- Captures lint, dust, and airborne particles
- High-loft fiber web allows efficient filtration with low resistance
- Designed for consistent airflow throughout service life
- 30-90 day media replacement interval
- Reusable frame system reduces long-term cost
- Compatible with optional carbon insert for odor control
Best balance of filtration, airflow, and value
Best for: Homeowners who want real filtration without restricting their HVAC system
Disposable Pleated Filters
MERV 8-13 · Designed for one-time use
- Airflow decreases as pleats clog
- Increased blower motor strain over time
- Creates cardboard, metal, and plastic waste
- Easily bent or damaged during installation
- Can collapse or be pulled into system under pressure
- Higher long-term replacement cost
Higher filtration, but at the cost of airflow
Best for: Situations requiring high-MERV capture where airflow impact is acceptable
