The CoolMax is a NIOSH-approved N95 sanding, drywall and fiberglass respirator. Its patented design allows workers to breathe up to two times easier and it lasts up to three times longer than other disposable masks. The mask feels cooler because it filters more air with each breath, reducing trapped heat and humidity. The respirator allows you to inhale and exhale easier, eliminating the need for a valve. A soft polyester binding, flexible material and adjustable nosepiece allows for a better, more secure fit. The large surface area keeps you from sounding muffled when talking. The respirator folds easily for convenient storage and limited reuse.
