Product Overview
The 3M Particulate Respirator 8577, P95 is a disposable respirator designed to provide reliable respiratory protection. It offers at least 95 percent filtration efficiency against certain oil and non-oil based particles. A key feature is its carbon layer, which helps reduce exposure to nuisance levels of organic vapors, including those from solvents, degreasers, and resins. This respirator is suitable for various applications such as foundry operations, lab settings, agriculture, petrochemical manufacturing, and undercoating where particles and nuisance levels of organic vapors may be present.
The design incorporates braided headbands and an M-Noseclip for easy adjustment, aiming to reduce pressure points and enhance comfort. It utilizes 3M’s proprietary technology with advanced electrostatically charged microfiber filter media, facilitating ease of breathing. The respirator is compatible with a range of protective eyewear and hearing protection. Equipped with a 3M Cool Flow Exhalation Valve, it is particularly well-suited for environments with heat, humidity, or for extended periods of wear, as the valve helps release hot, humid exhaled breath quickly, reducing heat buildup.

Setup and Fitting Instructions
Proper fitting of the respirator is crucial for effective protection. Follow these steps to ensure a secure seal:
- Inspect Respirator: Before each use, inspect the respirator for any damage, tears, or deformities. Do not use if damaged.
- Position Respirator: Hold the respirator in your hand with the nosepiece at your fingertips. The headbands should hang freely below your hand.
- Place on Face: Position the respirator under your chin with the nosepiece up.
- Secure Headbands: Pull the top headband over your head, resting it high on the crown of your head. Pull the bottom headband over your head and position it around your neck, below your ears.
- Adjust Noseclip: Using both hands, mold the M-Noseclip to the shape of your nose by pressing downwards and inwards. Ensure a tight seal around the nose bridge.
- Perform Seal Check:
- For respirators without an exhalation valve: Place both hands completely over the respirator and exhale sharply.
- For respirators with an exhalation valve (like Model 8577): Place both hands completely over the respirator and inhale sharply.

Operating Instructions and Usage
The 3M Particulate Respirator 8577 is intended for industrial/occupational use only and is not for consumer sale or use. It is designed to protect against certain oil and non-oil based particles and to provide nuisance level relief from organic vapors.
- Use this respirator in accordance with all applicable health and safety regulations and standards (e.g., U.S. OSHA, ANSI).
- Ensure the respirator is properly fitted and a seal check is performed before entering any contaminated area.
- Do not use this respirator for protection against gases or vapors that are immediately dangerous to life or health (IDLH).
- Do not use this respirator in atmospheres containing less than 19.5% oxygen.
- The carbon layer provides relief against nuisance levels of organic vapors. "Nuisance levels" refers to concentrations not exceeding OSHA PEL or applicable government occupational exposure limits, whichever is lower.
- Replace the respirator if it becomes damaged, breathing becomes difficult, or if you can smell or taste contaminants.

Maintenance and Storage
The 3M Particulate Respirator 8577 is a disposable product and requires minimal maintenance. Proper storage is essential to maintain its effectiveness.
- Disposal: Dispose of the respirator when it becomes damaged, breathing resistance increases significantly, or at the end of the shift, whichever comes first. Follow local regulations for disposal of contaminated materials.
- Cleaning: This respirator is not designed to be cleaned or disinfected. Do not attempt to wash or clean the respirator, as this may compromise its filtration efficiency.
- Storage: Store unused respirators in their original packaging in a clean, dry area away from contaminants, extreme temperatures, and direct sunlight.
- Shelf Life: Refer to the product packaging for specific shelf life information.
Troubleshooting
If you experience any issues while using the 3M Particulate Respirator 8577, consider the following:
- Difficulty Breathing: If breathing becomes difficult, the filter may be clogged with particles. Replace the respirator immediately.
- Smelling or Tasting Contaminants: If you can smell or taste the contaminant, or if irritation occurs, the respirator may not be properly fitted, or its capacity to filter vapors may be exhausted. Immediately leave the contaminated area and check your fit. If the issue persists, replace the respirator.
- Discomfort or Pressure Marks: Ensure the headbands are positioned correctly and not overly tight. Adjust the M-Noseclip gently to conform to your nose without excessive pressure. If discomfort persists, the respirator size or type may not be suitable for your face shape.
- Respirator Slipping: Ensure the headbands are securely positioned, with the top band high on the crown of your head and the bottom band below your ears. The M-Noseclip should be molded firmly to your nose.
Always ensure a proper seal check is performed before entering any hazardous environment.
