Plasma cutter air filters help form a better arc and thus enhance the cut quality of plasma cutter. They do so by keeping dirt, water, and oil from entering the plasma cutter. If you don’t use an air filter with your plasma cutter, the moisture in the airline can cause damage inside the machine, and you may need to invest in a new machine.
Air filters only cost a few dollars (in some cases), so it's really worth having an air filter on your plasma cutter! Here are some of the best air filters for plasma cutters on the market right now!
Motor Guard M-30 Plasma Cutter Filter
Key Specifications
This air filter can be used for plasma cutters and spray booths. It is designed to filter dirty air that can damage machines. It can filter oil, condensed moisture, and particulates down to .01 microns! This is an excellent filter that can be used to 150 psi. Although, the filter may not last too long if you do that. However, for steady work at 100 psi or below, this air filter is excellent.
It is best to install a water separator in front of this air filter to trap as much water and oil as possible before it enters the air filter. This, of course, saves you needing to change the paper filter in this air filter all the time. With good separators in the line before this air filter, the paper filter can last over a year without the need to change it.

This is an excellent complete air system for a small workshop. This filter has three stages of defense against water and oil, so it is a simple solution for a hobbyist that wants to preserve the life of their plasma cutter or air tools.
The kit also comes with a pressure gauge, regulator and shut off value. Not many kits at this price do, so that is really nice to see. If you use an inline moisture trap before this filter, you can also prolong the life of the filter which needs to be replaced when indicated.

PneumaticPlus SAU4030M-N04DG-MEP
Key Specifications
This separator works brilliantly. It is excellent to use with any airlines or plasma cutters and would suit a medium-sized shop if using it with air tools. If you are, it is best used with at least 25ft between the compressor and the unit. This gives enough time for the copper piping to cool down the air and allows the water to form into large droplets so that this system can filter them out.
The automatic drains on this system work perfectly and makes this unit far easier to maintain. Just set up some plastic tubing on the outlet that feeds into a container and dispose of the water whenever needed. This is an excellent, hassle-free air filter for plasma cutters and air tools.
