This pre-filter fits Austin Air Bedroom Machine air cleaner models and meets HEPA standards, trapping 99.97% of all particulates larger than 0.3 microns. Excellent for those with severe chemical sensitivities. Foam gaskets on the top and bottom create a 100% seal, and a nearly 15 lb mixture of solid activated carbon Zeolite (impregnated with potassium iodide) removes harmful gases for the chemically sensitive.
