Upgrade your indoor air quality with Glasfloss Z-Series Air Cleaner Replacement Filters — the reliable alternative when it’s time to replace your original filter. The Z-Line 400 HW model is a compatible replacement option for Honeywell® F-100 cartridge filters.
These filters feature an extended-surface pleated design made from 100% synthetic media, engineered for superior dust-holding capacity and airflow. A galvanized expanded metal backing is laminated to the air-exit side using a thermo-setting adhesive, maintaining uniform pleat spacing and structural integrity while resisting rust and corrosion.
Each Z-Series filter includes moisture-resistant separators to protect pleat structure during operation, and the pleated media is securely bonded to a heavy-duty, moisture-resistant beverage board frame. The frame face is internally laminated to the pleat tips to ensure a tight, secure fit.
Every Glasfloss Z-Series filter is individually wrapped in a protective plastic sleeve to prevent contamination prior to installation. Designed to withstand temperatures up to 180°F, these filters are UL 900 certified and available in MERV 10, MERV 11, and MERV 13 ratings as tested under the ANSI/ASHRAE 52.2 standard.
🛒 Choose Glasfloss Z-Series for a high-performance, dependable air filter replacement — ideal for residential or commercial HVAC systems.
