WAREHOUSE DEAL 16x18x1 Flanders EZ Flow Fiberglass MERV 1-4 Filter (12 Filters)

Warehouse deal: closeout pricing on overstock inventory. Filters may show minor box wear or cosmetic imperfections from handling and storage. Each lot is inspected before listing and priced accordingly — filtration performance is unaffected. While supplies last. This 16″ × 18″ × 1″ Flanders EZ Flow spun-fiberglass panel filter (part number 10055.011618) ships as a case of 12 filters and is built for one job: protect your HVAC equipment while maximizing airflow. It's the category-leading fiberglass filter that's been keeping coils, blowers, and heat exchangers free of lint and large debris for decades. Understanding the MERV 1–4 rating Fiberglass media is rated MERV 1 when clean and builds up to MERV 4 as dust loads onto the fibers. That's not inconsistency — it's how spun-glass media works. A fresh filter lets the most air through while still blocking larger debris; as dust collects, the media becomes more efficient at catching finer particles. The goal of a MERV 1–4 filter isn't air quality — it's equipment protection with maximum airflow. It keeps lint, hair, and large dust out of your coil and blower, which is exactly what older systems, high-airflow applications, and pre-filter duty need. Equipment protection, not air quality EZ Flow isn't designed to filter fine dust, allergens, or smoke. It's designed to stop the stuff that damages HVAC equipment — lint, hair, large dust clumps, and insulation fragments — before they hit your coil or blower. For allergen filtration, step up to a pleated MERV 8 or higher. For system protection with maximum airflow (and the lowest filter cost in the category), EZ Flow is the right tool. Design and construction Media: Continuous-filament spun fiberglass, bonded with resinous adhesive for rigidity and compression resistance. Frame: One-piece heavy chipboard — no corner seams to separate. Media adhered directly to the frame with hot-melt adhesive, no metal retainer. UL listing: UL 900 listed. Service life: Replace every 30 days under typical use.
