The Smith Filter Thrift Aire Filter is a lightweight, washable aluminum air filter designed for light-duty commercial and industrial HVAC systems. Constructed from multiple layers of expanded aluminum mesh, the filter is assembled in alternating layers to maximize dust-holding capacity, airflow uniformity, and internal loading efficiency.

It operates effectively up to 240°F (115°C) and provides low airflow resistance while maintaining excellent particle removal efficiency.

Available in standard and custom sizes with 1-inch, 2-inch, 3-inch, and 4-inch thicknesses, the Thrift Aire Filter delivers reliable, long-term filtration that reduces maintenance costs and environmental impact.
