Honeywell 14110403 N99 Disposable Respirator Med/lg

Product Description

The HONEYWELL 14110403 is an N99-rated disposable particulate respirator designed for medium and large face sizes. Rated by NIOSH under approval number TC-84A-3845, this respirator filters at least 99 percent of airborne particulates, making it appropriate for environments with elevated dust, fine particles, or other non-oil-based airborne hazards. It features an adjustable elastic strap for a secure fit, an exhalation valve to reduce heat and moisture buildup during extended wear, and a face seal designed to minimize air leakage around the edges. It is sold in a package quantity of 10 units and is intended for use by trained workers who have been properly fit-tested for this style of respirator.

This respirator is well-suited for trade professionals working in environments that generate fine particulate matter, including HVAC technicians handling insulation or duct cleaning, plumbers working in older structures with potential dust hazards, electricians in dusty job sites, and pool service pros working around chemical powders or diatomaceous earth. The N99 classification places it above the more common N95 standard, offering a higher level of particulate filtration for more demanding work conditions. Each unit is intended for single-use, disposable application.

Installation Notes

Respirator selection and use must comply with OSHA 29 CFR 1910.134, which requires a written respiratory protection program, medical evaluation, and fit testing before use. Inspect the respirator before each use and discard if the face seal, straps, or valve are damaged. Do not use in atmospheres immediately dangerous to life or health or in environments containing oil-based aerosols, as this unit is not rated for those conditions. Proper donning procedure and seal checks should be performed each time the respirator is put on.
