With the rise of environmental concerns, occupational hazards, and health issues related to poor air quality, the demand for respirators has seen a significant increase. Respirators are crucial for protecting individuals from inhaling harmful particles, gases, and vapors, making them an essential piece of personal protective equipment (PPE) in various settings, including industrial, medical, and everyday use. However, the process of buying a respirator can be daunting due to the vast array of options available, each designed for specific needs and environments. This guide aims to navigate through the complexities of respirator selection, highlighting key factors to consider, types of respirators, and how to ensure the chosen respirator meets your safety needs.
Understanding Respirator Types and Uses
Respirators are broadly categorized into two main types: air-purifying respirators and supplied air respirators. Each type is designed to address different hazards and working conditions.
Air-Purifying Respirators (APRs)
Air-purifying respirators work by removing contaminants from the air. They are suitable for use in environments where the air is contaminated with particles, gases, or vapors that are not immediately dangerous to life or health. APRs are commonly used in construction, manufacturing, and healthcare settings. Within APRs, there are several subtypes, including:
- Particulate Respirators: Designed to capture at least 95% of airborne particles, these respirators are often used to protect against dust, pollen, and other particles.
- Gas and Vapor Respirators: These respirators use chemical cartridges to remove gases and vapors from the air, offering protection against a wide range of chemical hazards.
Supplied Air Respirators (SARs)
Supplied air respirators, on the other hand, supply clean air from a source outside the contaminated area, providing a higher level of protection than APRs. SARs are used in more hazardous environments where the air may be immediately dangerous to life or health. This type of respirator is often used in confined spaces, during entry into IDLH (Immediately Dangerous to Life or Health) atmospheres, and in fire fighting.
Factors to Consider When Buying a Respirator
Selecting the right respirator involves considering several critical factors. Among these, the nature of the hazard (particles, gases, vapors, etc.), the concentration of the contaminant, and the work rate and duration of the task are paramount. Here are some key points to consider:

Comfort and durability are also important factors. A respirator that is comfortable to wear over extended periods will encourage compliance, ensuring the wearer’s safety. The durability of a respirator and its components (filters, cartridges, etc.) should also be considered, as it impacts the overall cost-effectiveness of the respirator.
Regulations and Standards
The respirator market is regulated by various national and international standards. In the United States, for example, respirators must meet the standards set by the National Institute for Occupational Safety and Health (NIOSH). NIOSH approval ensures that the respirator has passed rigorous testing for efficiency and safety.
NIOSH Approval
Looking for the NIOSH approval label is crucial when purchasing a respirator. This label indicates that the respirator has been tested and certified to meet specific standards of performance. NIOSH issues different classes of approval (e.g., N95, N100, P100) based on the respirator’s efficiency in filtering out airborne particles and its resistance to oil.
Other Standards and Certifications
In addition to NIOSH, other organizations such as the Occupational Safety and Health Administration (OSHA) and the American National Standards Institute (ANSI) provide guidelines and standards for respirator use and selection. Familiarizing oneself with these regulations and standards can help in choosing a respirator that not only protects the wearer but also complies with legal and regulatory requirements.
Purchasing and Maintenance
Once the appropriate respirator has been selected, the next steps involve purchasing and maintaining the equipment.
Where to Buy
