This welding fume extractor provides a cheap filtering system for a MIG welder. It will eliminate the need for respirators or other safety gear during welding operations.

Place it as close as possible to where the fumes are released but ensure it’s not so close that it gets damaged by sparks or other hot objects flying around in the area you’re working on.

5. Shop Air Filter Fume Extractor Combo by Instructables 

Materials Needed: A tunnel fan, fine mesh fabric, wood glue, small pin nails, wire cables, screws, and four small blocks of wood
Tools Needed: Table saw, miter saw, and a jigsaw
Difficulty Level: Moderate

The Three-Way Shop Air Filter Fume Extractor Combo is an excellent choice if you want to use a shop air filter as a fume extractor. This unit is designed to work with a standard four by 20-inch ductwork system. It should be more than adequate for most welding applications.

The kit comes with everything you need to assemble it. All the instructions are included in the package as well. It’s perfect if you want something that will get the job done without spending too much money on it.

The best type of shop air filter for a welder is the one that uses activated carbon. You can also find one that uses charcoal filters to trap particles and gasses in the air before they reach the filter itself. You should also choose an air filter with easy access to replacement parts. This way, you can keep it working well over time.

6. Homemade Welding Fume Extractor by Youtube 

Materials Needed: PVC pipe, duct tape, a long piece of galvanized steel tubing, bolts, a fan, and some wire
Tools Needed: An angle grinder, drill, jigsaw, and a screwdriver
Difficulty Level: Easy

If you’re looking for something simple but effective, a homemade welding fume extractor might be a good start. It’s one of the most popular DIY fume extractor options. Also, it’s cheap and easy to assemble. 

This extractor uses an air compressor to draw fumes from the work area into a carbon filter. It’s made of PVC pipe and duct tape. It works by pulling air into the top of the PVC pipe. Then, it pushes it out through holes drilled in the bottom.

The only downside is that it won’t be as powerful as other options. But, if you’re only doing occasional small jobs at home, it should do the trick.

It uses some duct tape and a length of flexible tubing. The only cost is for the tube and the duct tape. So, it won’t break the bank at all!

The extractor works by sucking air from the welding area through a filter screen. The fumes then pass through an exhaust fan where it’s pushed out of the building through a flexible hose connection.

The filter screen removes dust particles from the air stream before reaching the lungs. This design is great for hobbyists who don’t want to spend much money on their first project.

8. DIY Fume and Smoke Extractor by Bbq grills plus 

Materials Needed: Attic fan, duct reducer, flexible duct, and a degree duct fitting
Tools Needed: Drill bit and a screwdriver
Difficulty Level: Moderate

The DIY Fume and Smoke Extractor works on the principle of air suction and filtration. It’s the same as most commercially available dust extractors. Also, it’s one of the simplest plans for building your welding fume extractor.

This welding fume extractor uses basic materials such as PVC pipe and aluminum foil for making the fume collector’s hood.

The airflow from the fan is directed into the PVC pipe that goes into the garage or workshop area. This way, the fumes can be expelled outside.

What are the Benefits of Using Welding Fume Extractors?

Welding releases harmful fumes and smoke into the air. It can be dangerous for both people and animals. There are many ways you can prevent this from happening, but one of the best ways is by using welding fume extractors.

Here are further benefits of using welding fume extractors:

Odor Prevention

Welding fumes have an unpleasant odor that lingers for days after you finish a project. Many types of welders use oxygen and acetylene gas during the process. Both gases have distinctive odors. A welding fume extractor will prevent this problem by removing all traces of these odors.


Welding fumes contain toxic substances, such as lead, chromium, manganese, etc. These fumes can cause severe health problems if inhaled over long periods. Fume extractors are a sure way of mitigating these problems.

Productivity Levels

Welding without using fume extractors will reduce your productivity levels. It’ll take you longer to complete a task. You have to stop working now and then to catch your breath as you are exposed to these toxic vapors or gases.

Improved Visibility When Welding

One of the most common complaints by welders is that their vision becomes blurry when working with certain metals for long periods due to exposure to harmful fumes.

An extraction system will improve visibility by removing all traces of smoke from the area. It allows welders to perform their duties more efficiently with clearer vision and greater accuracy.

They Reduce the Risk of Fire Accidents

Fire is one of the most common causes of industrial accidents. Welding fumes can cause fire or explosion when they come into contact with combustible materials or vapors. Even small sparks from welding machines can ignite these hazardous vapors. You need to install a welding fume extractor to prevent this from happening.

These devices remove harmful fumes before they reach any flammable materials or vapors.


Welding fumes are a dangerous byproduct of the welding process. Welders should make a safety plan to mitigate these byproducts. You can assemble an efficient and effective welding fume extractor for any project size with these DIY plans.

These eight DIY welding fume extractor plans have something in common. They’re cheap to make, and they will get the job done. Choose one today, and your welding session will be a pleasant one with the unwanted fumes being taken care of.
