YIDINGAIR FILTRATION
Product overview
What it is and where it fits.
The AR101 is a washable mesh prefilter for the first stage of an air handling system. Single- or double-layer PE, PP or nylon mesh is formed on a welded-wire support and finished with a stitched black plastic edge, so the filter can be cleaned and reused instead of replaced.
It stops coarse dust, fibres and insects at outdoor-air and return-air intakes and protects the medium-efficiency filters downstream. The catalogue lists gravimetric efficiency above 65% (ASHRAE 52.1) with a very low initial pressure drop.

Construction & performance
Design & maintenance
Single- or double-layer PE, PP or nylon mesh is formed on a welded-wire support with a stitched black plastic edge. The washable construction is easy to clean and maintain.
Media & frame options
Galvanized or stainless steel wire support; optional galvanized steel, aluminum or stainless steel outer frames.
Filtration performance
The catalogue lists gravimetric efficiency above 65% under ASHRAE 52.1-1992. Single- and double-layer sizes and pressure-drop values are listed below.
Selection guide
How to choose.
Single or double layer
The double-layer version collects more dust at a slightly higher pressure drop; the single layer suits low-resistance intakes.
Frame for the environment
Wire-only filters are lightest; add a galvanised, aluminium or stainless outer frame for rigidity or humid, corrosive sites.

Common questions.
Can nylon mesh filters be washed?+
Yes. The mesh and wire support are designed to be cleaned with water or compressed air and reused. Let the filter dry before reinstalling it.
Where is a mesh prefilter used?+
At the very first stage — outdoor-air and return-air intakes — to stop coarse particles and insects so that the pleated, pocket and HEPA filters downstream last longer.
