Cartridges & Filters

Respiratory Cartridges & Filters

Breathing is important. In fact, you can’t live without it and protecting your lungs will make breathing a lot easier. That’s where cartridges & filters come in.

Cartridges and filters are an important part of respiratory protection because they are the devices that actually clean the air you are breathing in. Cartridges and filters are used in a range of different types of respirators. While they are used in disposable respirators, the cartridges and filters in this section are not compatible with any type of disposable respirator since disposable respirators are not supposed to be reused.

When picking out cartridges and filters there are a few main things to consider.

What hazards are you going to be exposed to? Have you assessed the situation? What level of protection do you need? What standards do I need to make sure I’m in compliance with? These questions will ensure that you are following best practices in making your decision when purchasing respiratory protection.

Filters can have one of 3 letter class ratings:

→Class N – Not oil resistant

→Class R – Resistant to oil

→Class P – Oil proof

Filters will also have one of 3 number class ratings:

→95 – filters 95% of all particles measuring 0.3 microns or larger in diameter

→99 – filters 99% of all particles measuring 0.3 microns or larger in diameter

→100 – filters 99.7% of all particles measuring 0.3 microns or larger in diameter (this filter is typically an HE or HEPA quality filter)

You will generally see a filter class rating in this form: N95 or P100.
