Best Respirators Buying Guide
Since respiratory masks are designed to cater to a large variety of needs, there are a lot of variations in terms of the type of respiratory protection, efficacy, filtration, certification, cartridges, etc. When you’re looking for a respiratory mask, you need to make sure that you’re going for the right one. The self-contained breathing apparatus that is right for you is supposed to cater to your occupational safety needs in the most efficient and effective manner.
While most people would find it difficult to navigate through the different variations and options that are available, we have compiled a comprehensive guide that will make the entire process easier for you. This guide will help you purchase the best respiratory protection mask in 2024, making sure that all of your needs and requirements are met.
What Is the Difference Between Surgical Masks and Respiratory Masks?
A lot of people get confused about how a respiratory protection mask is different from a surgical mask and they tend to ignore the stark differences between the two. Failure to distinguish the functionality and use of a respiratory mask from a surgical mask would make it impossible for you to choose the right equipment according to the situation.
Purpose
To begin with, the core purposes of a respiratory protection mask and a surgical mark are different. While respiratory masks are supposed to provide protection against airborne particles, biological aerosols, viruses, and bacteria, surgical masks are supposed to protect you from splashes, spit, and droplets. Whichever mask you need will be determined by the occupational safety requirements of your job.
Filtration
While surgical masks are not designed to effectively catch small particles, respiratory protection mask filters can effectively filter out small particles. The ability of a respiratory mask filter to collect small particles can be determined by the rating that a certain filter has. The rating of a filter corresponds to the percentage of aerosol that a filter is capable of catching and this concept is further explained in the section below.
Usage
Surgical masks are not designed to fit tightly onto the face of the wearer. On the other hand, respiratory protection masks are designed to seal tightly onto the face and operate using compressed air, leaving no room for excessive air particles.
What Do Respiratory Mask Ratings Mean?
Since a respiratory mask is an important piece of occupational safety equipment, it is usually certified and evaluated by a designated body in the health division and it is the same body that gives ratings to respiratory masks. While the ratings might seem like meaningless numbers to anyone that does not understand how it works, ratings are actually quite important and you must understand what they indicate.
The first part of a respiratory protection mask’s rating is a single letter. These masks are categorized under three different letters. Here is what each of the letters means:
- P: A ‘P’ at the beginning of the rating indicates that the mask is oil-proof/oil resistant.
- R: An ‘R’ at the beginning of the rating indicates that the mask is partially oil resistant
- N: An ‘N’ at the beginning of the rating indicates that the mask is not resistant to oil.
The second part of a respiratory protection mask’s rating is a double-digit number, which indicates how effective a respiratory mask is. The double-digit number is the effectiveness of a mask, for example, a ‘99’ rating means that the mask is capable of filtering at least 99% of the particles.
What Are the Types of Respiratory Masks?
Since respiratory protection masks serve a variety of purposes, it is important to understand which type of respiratory mask is suitable for the situation at hand. Here are the most commonly utilized types of respiratory masks:
N/P/R-Series
N-series, P-series, and R-series aren’t mechanical or electrical, neither do these contain carbon-based cartridges. These masks are most commonly categorized as particulate filters and not as gas respiratory masks.
Half-face respiratory masks
Half-face respiratory protection masks are designed to provide a relatively higher level of protection. These masks come with two filter cartridges that are supposed to provide fresh, breathable, not compressed air to the wearer.
Full-face respiratory masks
As suggested by the name itself, full-face respiratory protection masks are supposed to provide protection to the entire face, which is particularly important when you have to work in an environment where you will be exposed to hazardous materials.
Electrical full-face masks, also known as supplied-air respirators, are used while operating in dangerous environments, as these are capable of supplying breathable compressed air to the wearer.
Mechanical full-face masks are used in relatively less dangerous environments as these are capable of ensuring that there’s enough oxygen by clearing out the CO2.
Vapor/Gas masks
Vapor or Gas masks could be in the form of a half-face or a full-face mask, with an attached cartridge. There are four categories of cartridges, coded in colors, and each of them is responsible for filtering out a certain kind of hazard (vapors/gases).

Things To Look Out for While Buying a Respiratory Mask
When you’re looking for suitable air-purifying respirators, here are the things that you should be looking out for:
Type
The first and foremost thing that you should be sure about is the type of respiratory protection mask that you need, according to the occupational safety situation. This guide has extensively covered the types of respiratory protection masks above, which will help you develop a thorough understanding, enabling you to be able to choose the right equipment for the right situation.
Fit
The fitting of a mask is quite important because it determines the amount of respiratory protection that it will be able to provide. Ideally, respiratory masks (except for the N/P/R-series) should fit properly onto your face, leaving no room for contaminated and hazardous materials to penetrate through.
Expiry date
Respiratory protection masks, filters, and cartridges are only good for a certain period of time. While purchasing a respiratory mask, you need to make sure that it is not expired. Expired masks must not be used at any cost, as they are not suitable for use in any form.
Certification
When dealing with sensitive products, especially those associated with pharmaceuticals and healthcare, one must be very vigilant about the certifications and approvals that a certain product has. National Institute for Occupational Safety and Health (NIOSH) is an example of an institute that provides reliable certifications and it would be a good idea to purchase a self-contained breathing apparatus that has been approved and certified by NIOSH or any other relevant body.
People Also Asked
Can respiratory masks be reused?
While some air-purifying respirators are disposable, others are designed to last longer. The best way to go about this is to carefully go through the instructions provided by the manufacturer and check if you can reuse your respiratory masks or not.
Which is the best material for a respiratory protection mask?
Respiratory masks can be made of a variety of materials, including wool felt and polypropylene, depending upon the type. In essence, there is no best material and any material that does the job well and is comfortable, is the most suitable one for you.
