A respirator, such as N95 face masks is a specially designed device for protecting the wearer from hazardous environmental particles by filtration. Other respirators purify the air by adsorbing vapor or gases on a sorbent in a canister. Do you want to know more on what the reviews depict about respirators? Worry no more as this article has got you covered.

Forms of respirators

• Mouth bit respirators, which mainly fit the mouth such as N95 face masks. Besides, many of them come with a nose clip to keep the nostril closed and only open for escape purposes.
• Quarter mask covers the mouth and nose just like N95 respirators.
• Half face mask extends from the nose to the chin
• Full face piece covers the face from eyes to the chin.
• Respirators with an entire face piece protect the eyes from getting exposed to irritating chemicals.

How to select the best respirator

Choosing the right respirator can be a complicated experience. Typically, safety professionals who have work experience are the best people who can guide you in selecting the best respirator. This is coined to the fact that such individuals have high knowledge of respirators used in various environments. Here are some of the factors that need to be considered when selecting the respirators as outlined by the professionals, read on!

• Check on respiratory hazard
• Evaluate the hazard
• Check whether the respirator has engineering control
• Consider whether it should be used for firefighting or emergency.
• Consider the nature of the hazard such as chemical properties, warning properties, and concentration in the air
• Consider whether the respirator should be used to control more than one contaminant
• Consider the kind of job to be done while wearing the respirator
• Check on the health impacts of contaminants, such as carcinogenic, irritating to the eyes, potentially lethal, and others.
• Determine whether the airborne levels are below or above the exposure limit
• Check whether the environment has more than one contaminant, that is the presence of more than one chemical.

Tight- and loose-fitting respirators

Respirators are either made of loose-fitting or tight-fitting inlets. When it comes to the latter, they have a half or full face pieces. On the other hand, the former can be helmets, or hoods that cover the head and neck, and are mainly supplied with air via airlines. Example of respirators found here includes:

• Air-purifying respirators (APRs):
• particulate respirators
• chemical cartridge respirators, which may have a combined chemical centrifuge and dust prefilters. The combination given here protects the wearer against various contaminants found in the air.
• powered air-purifying respirators (PAPRs).
• Supplied-air respirators (SARs):
• self-contained breathing apparatus (SCBA),
• airline supplied-air respirators,
• protective suits, which are mainly meant to encapsulate the body of a wearer and incorporate a system of life-support.
