Product Description
Flanders EZ Flow II - 16x20x1 Inch Fiberglass Panel Furnace Filter, MERV 4, UL 900 Listed, 12-Pack Case for Residential and Light Commercial HVAC
Flanders EZ Flow II 16x20x1 inch fiberglass panel furnace filter, 12-pack. Continuous-filament spun fiberglass media protects your HVAC system from lint, hair, large dust clumps, and insulation fragments that damage coils and blowers. UL 900 Listed and built for high airflow with low static pressure drop. Ideal for equipment protection, older HVAC systems, rental properties, workshops, and as a pre-filter ahead of a higher-MERV filter.
Top Features
- 12-Pack Value: One case of 12 filters delivers a full year of monthly changeouts for a single-return residential system - less reordering and lower per-filter cost.
- MERV 4 Peak Protection: Rated MERV 1 when clean and builds to MERV 4 as dust loads onto the fibers - designed for equipment protection with high airflow, not fine particle filtration.
- Continuous-Filament Spun Fiberglass Media: Resinous adhesive bonds the fibers for consistent loft and reliable capture of lint, hair, large dust clumps, and insulation fragments.
- Heavy Chipboard Frame: One-piece construction with no corner seams, hot-melt adhesive media attachment, no metal retainer - easy to recycle and dispose.
- UL 900 Listed: Independently tested to the UL 900 air filter standard for safe operation in residential and commercial HVAC systems.

Flanders is a brand of AAF Flanders (American Air Filter), a global leader in air filtration for residential, commercial, and industrial applications. The EZ Flow II panel filter is UL 900 Listed per the current UL air filter safety standard. MERV rating is determined per ASHRAE Standard 52.2 lab test methodology; actual performance in any specific HVAC installation varies with system airflow, duct design, and operating conditions. Install the filter with the airflow arrow pointing toward the blower. For maximum equipment protection, replace monthly - more frequently in high-dust environments (renovations, construction, pets, wildfire smoke). This filter is designed for equipment protection with high airflow, not for improved indoor air quality - for allergens, smoke, or fine particle filtration, upgrade to a MERV 8 or higher pleated filter.
