Respiratory Protection

What is the difference between N95, R95, and P100 ratings?

These ratings indicate the filter's efficiency and its resistance to oil. N95 masks filter at least 95% of airborne particles but are not resistant to oil. R95 masks are also 95% efficient but are resistant to oil-based aerosols for up to 8 hours. P100 filters offer the highest level of protection, filtering 99.97% of particles (equivalent to HEPA standards) and are fully oil-proof.

Should I choose a disposable mask or a reusable respirator?

It depends on your frequency of use and environment. Disposable masks (like the N95 Flatfold or Molded Cup) are lightweight and convenient for one-time tasks like sanding or sweeping. Reusable respirators (Half-Mask or Full-Face) are more cost-effective for long-term use; they feature durable elastomeric facepieces and replaceable cartridges that can be swapped out based on the specific hazard, such as organic vapors or ammonia.

How do I ensure a proper seal, especially if I wear glasses?

A secure fit is critical for protection. Honeywell respirators often feature molded nose bridges and dual welded head straps to maintain a tight seal. For those with eyewear, many models are designed with a low-profile bridge to reduce fogging and ensure compatibility. For the best results, perform a "user seal check" by covering the filters with your hands and inhaling/exhaling to ensure no air escapes through the edges.

Can I use these masks for protection against chemicals and gases?

Standard N95 or P100 disposable masks are designed for particulate matter (like dust, soot, or allergens) and will not protect you against chemical vapors or gases. If you are working with paint thinners, pesticides, or industrial chemicals, you should use a Reusable Half-Mask or Full-Face Respirator equipped with the appropriate Chemical Cartridge (such as an Organic Vapor or Multi-Acid Gas cartridge) specifically rated for those substances.
