AAF Flanders MERV 15 Air Filters

MERV 15 from AAF Flanders covers the full commercial product range at this efficiency tier — VariCel and VariCel II — the highest non-HEPA efficiency tier. Every MERV 15 filter in this collection is manufactured by AAF Flanders, tested per ASHRAE 52.2, UL 900 Classified where applicable, and Section 889/NDAA compliant for federal procurement.

What MERV 15 Captures

MERV 15 reaches 85%+ efficiency at 0.3 microns — the highest efficiency below true HEPA. Used for surgical operating room pre-filtration, IVF and oncology clinics, semiconductor cleanroom pre-filters upstream of HEPA, and any application requiring HEPA-adjacent filtration without the cost and pressure drop of full HEPA.

Application Fit

  • Operating room pre-filter (upstream of HEPA)
  • Compounding pharmacy pre-filter
  • Semiconductor and electronics pre-filter
  • IVF, oncology, and high-acuity clinical
