Best Homemade WVO Filter

What is the best way to make a homemade filter for filtering wvo? I don't want to have to buy expensive filters for the rest of my life, and I want to not have to go to the store specifically for filters.

I've heard that using old jeans was a good way to filter wvo for the big stuff, but does someone have an idea how to filter it down to the smaller microns, without having to support a huge manufacturing plant and all it's employees, just to get down the road? :)

wvo filtering

After a year of design and testing I'm proud to say that my filtering system works great. The whole project cost about $300 and removes all water and particles down to 5 micron. The process starts with pouring the used oil into a five gallon bucket mounted over a 30 gallon transparent drum. The oil flows through a straining bag into the drum and permitted to settle. The water is allowed to accumilate at the bottom and can be drained from the bottom tap. The product is then pumped from the primary drum eight inches above the drain to avoid the contaminated oil. The oil then passes through a 30 micron Stanadyne FM100 filter, the Filrite pump and then another Stanadyne FM100 5 micron filter to the secondary holding drum or the car tank. This method has worked, without fail for almost a year before changing the FM100 filters. The screening bag filter is easy to clean in the washing machine about every month and allowed to dry. If I can help please give a write:

Babington style waste oil heater pumps

The cam gear pump works fine for filtered WVO or used motor oil Babington heaters and I have installed it on my Babington style heaters. Ldu Company's stock number is 450516 , The only thing about the cam gear pump is that the fire kind of pulses as the cam gear rotates. If you use the spur gear pump that is LDU's stock number 450512 then you get a steady non-pulsing fire. The WVO pump website is or you can click through to the tools section from the home page at

LDU Company also has other parts that I use for building my waste oil burners, like gear reduction motors. I find it best to turn the pump slower because you really don't need a whole lot of oil dripping on the atomizer ball.
