The Honeywell H901 N95 Respirator Mask for Airborne Particulates provides 95% filter efficiency against solid and liquid particulates in the air. This includes work-related irritants like dust, sawdust and airborne allergens. Lightweight, easy-to-wear and disposable, N95 masks features a latex-free filter media for lower breathing resistance. The breathing mask’s filter media is designed to resist humidity for comfortable performance in most environments. The two-strap construction allows for quick donning, while the adjustable nose bridge means one size will fit most faces. This face mask is an N class respirator that is approved for use with solid and liquid particulates, excluding oils.
