Zenith N95 particulate respirator for protection from solids & non-oil based liquids particles


Return conditions : Non returnable, final sale

Zenith N95 NIOSH 42 CFR 84 approved particulate respirator for protection from airborne particles. Sold per box of 20 units, 20 boxes/case.

This respirator is made of electrostatically charged microfiber that makes breathing easier and cooler. It is certified N95 which means it protects the user from 95% of particles in the air. The letter "N" stands for "non-resitant", thus the membrane doesn’t protect one from oil-based particles, but protects from solid, liquid and biological airborne contaminants.

The R497 respirator features fastening straps are held securely and a flexible foam coated nosepiece which allow a better impermeability without putting aside comfort. It does not contain natural rubber latex. Made in Taiwan.

This type of respirator offers a basic protection and eases the wearing of safety glasses.

Use for:
This product is made for short-term work in a controlled environment. It is design for grinding, sanding, sweeping, bagging, woodworking, foundries and other dusty operations. It can be used for protection from processing minerals, coal, iron ore, flour and other dusty substances, and non-oil-based liquids and sprays that do not emit harmful vapours. NIOSH certified respirators (N95, N100, R95, R100, P95 and P100) protect one from silica, the second main cause of chronic respiratory problems after asbestos.

Biological particles:
This respirator can help prevent the inhalation of certain airborne biological particles like mold, Bacillus anthracis (Anthrax), Mycobacterium tuberculosis (Tubercle bacillus Koch) the main causative agent of tuberculosis, pandemic flues (H5N1, H1N1), etc. It is by far the most used respirator when a pandemic occurs. However, it cannot eliminate the risk of contracting infection, illness or disease. Combined with hygiene and protection measures, this respirator turns out to be an efficient equipment to reduce the spread of infectious diseases. Due to the nature of some contaminants, the exposure limit value of some products and by products haven’t been quantified by governmental agencies, thus wearing a respirator doesn’t necessarily protect you.

Do not use for:
Do not use on a beard and other facial hair or if the user suffers from a condition that prevents him from having direct contact with the respirator’s sides. The use of respirators is not recommended for people with compromised respiratory systems such as asthma or emphysema. It is strongly discouraged from wearing a respirator for applications with oil-based spray, brush painting, gases, vapours, asbestos and sandblasting.  It is also highly advised to stay away from an environment that exceeds 10 times the permissible exposure limit set by the CNESST or any other government regulation applicable. One should never use a respirator in an oxygen-deprived environment (an atmosphere with less than 19,5 % oxygen).

Whenever the respirator is well adjusted and a qualitative fit test is successful, this respirator meets ANSI Z92.2-1992 standards, that is, a protection factor of 10. This factor means that the worker can be exposed to a concentration 10 times higher than the exposure limit when not protected. If needed, please contact customer service for more information.

Maintenance and service life:
No maintenance is needed since this respirator is disposable. It has been design for an approximate service life of 8 hours. That number is in no way a reference since every work environment is different. The manufacturer’s limitations must be followed.
