Best Welding Respirators

Whether you are a hobbyist, amateur, or professional welder, you are being exposed to dangerous fumes and gases produced during the welding process. The levels of danger may vary, but hazardous elements in your welding fumes are omnipresent. When exposed to heat, fillers, bases, coatings, and paints create vapors and fumes. Protect your respiratory system from the fume plume and learn how to choose a quality welding respirator for your welding projects or profession.

Why Should You Use A Welding Respirator?

Welding’s silent hazards are numerous. Wearing a respirator is important because different welding materials present different hazards. The top culprits are filler metal, coatings, shielding gases, base metals, and various fumes created when heating these materials.

Welding fumes contain hexavalent chromium and zinc, which can cause long-term damage to the respiratory system. OSHA has limits in place to determine what qualifies as permissible exposure (PEL) to help protect welders from these two elements specifically. Beyond these two fumes, though, there are unforeseeable contaminates you may be inhaling.

Correctly sized and fitted respirators offer protection from fumes, particles, and vapors. When you are working in an area without proper ventilation or local exhaust it is especially important that you use a respirator. Some of the health consequences welders can suffer from due to improper use or complete lack of respirators are: 

  • Asthma
  • Central nervous system issues
  • Irritation of the nose and throat
  • Flu-like symptoms from zinc fumes found in galvanized steel
  • Lung cancer

The bottom line is this: we really don’t know the consequences of long-term exposure to many of these fumes or even the content of the fumes themselves. Welding fumes are essentially composed of metallic oxides, fluorides, and silicates. While we might not be able to measure out the exact levels for every job performed, we do know that it is harmful to the body to inhale them consistently.

Other hazardous factors to think about are the paints, coatings, and solvents that the materials you are working with may be coated in. These create another element of uncertainty and quite a cocktail of elements in your welding fumes. Respirators serve to let you breathe clean, uncontaminated air in and keep contaminants out.

Runs small

Many people found they had to size up with this mask even though they didn’t necessarily have a large face.

Fit changes with face angle

Make sure to fit the mask while holding your head at the angle you will be working at. Some users found the fit changed as they re-positioned their heads (looking up versus looking down)

5. 3M Full Facepiece Reusable Respirator 6700

3M Full Facepiece Reusable Respirator 6700


Wide field of vision

Picking a filter can be confusing

This respirator works with so many different filters and is so versatile that some users are complaining about it. There are hundreds of options each for different applications. There is a chart available, but it would be nice if it was easier to read.

Debris can mark face shield

Users recommend you get a face shield protector to prevent debris from etching the mask. Once the mask is etched it is difficult to find the right size to replace it with.

Types of Welding Respirators  

Disposable Half Facepiece Respirators

Half-mask respirators extend from the welder’s nose down to the chin. For these respirators to work properly, it is imperative that there is a tight seal around the face. The mask should be able to fit securely underneath a welding helmet without veering into the welder’s eye line. There are three different filters that are paired with half-mask respirators.

  • N - non-oil resistant
  • R - oil resistant
  • P - oil proof

Filters are then categorized further by filter efficiency (how much can permeate the mask). There are 95%, 99%, and 100% efficiency options available. The highest protection you can use is P100, a completely oil proof filter that keeps out 99.97% of airborne particles.

Elastometric Half Facepiece

This is another half facepiece option with replaceable filters. It is composed of a silicone facepiece that covers from nose to chin. The Elastometric respirator requires custom fitting. It is reusable after decontamination, which is a big plus for users. They can be used for both particulates or vapors if used with cartridges or canisters instead of only particle filters.

Powered Air (Available In Both Headpiece And Hardhat)

Air purifying respirators use a powered blower to offer an air-purifying element via a hose into the welder’s helmet. This is a higher level of protection when compared with the half respirator. The system uses lightweight battery packs and shoulder straps to power the blowing units. Some Powered Air Purifying Respirators (PAPR) have flip-up lenses to expose grinding shields so that welders can either weld or grind without having to break the respirator seal or remove their helmets. PAPRs have filters that remove 99.97% of particles. Air flow from PAPRs not only purifies air, they serve to keep the welder cool.

Supplied Air Respirators

Supplied Air Respirators deliver clean air to the welder from an air-purifying panel via an air hose. These also serve to cool the air entering the welder’s helmet to prevent heat related injury. The sealed helmet is connected to the clean air as it is continually circulated throughout.

What To Look For In A Welding Respirator

So what factors will you need to take into account when selecting a respirator? You will need one that not only fits your face but also your work environment. Here are some factors to consider:

Work Environment

What kind of contaminants will you be exposed to while welding? Is there proper ventilation in your work space? Are you at risk for overheating on the job? Consider these questions when deciding the level of protection, you will need.


Consider how exposed you will be to contaminates. Will you need a half face piece or a separate air supply that goes to your enclosed and sealed helmet?


Whether you go with a half facepiece or a sealed helmet respirator, if the seal is not strong your respirator will not be effective. The fit is crucial and cannot be emphasized enough. The mask should sit tightly on the face, not letting any outside air in through the edges.


If you are not using a respirator with powered or supplied air, you will need to decide which percentage filter you will need. If you are working with gases or vapors you might additionally need a cartridge or canister. Know your contaminates and decide accordingly.


It will be hard for you to do your job if your respirator is clunky or uncomfortable. It should be sized and fitted correctly and beyond that the design should be ergonomic. In recent years respirators have come a long way in this department. Having a comfortable respirator is key for productivity and encourages welders to wear their respirators at all times.

If you are still confused about what type of respirator is right for you and your job, visit the OSHA website and use their online eTool to help you choose.


There are a lot of respirators out on the market to protect your lungs and nervous system while you weld. That being said, there are only a few that may be right for your protection needs. Be sure to consider all of the factors we’ve discussed before purchasing a respirator and get it fitted for your face and to fit comfortably under your hood or helmet.

Proper respiration is key to preventing hazardous particles, fumes, and vapors from entering your lungs. Invest in a respirator that will offer you the unique protection your welding activity requires.
