Another MYOG pre-filter

Good job, I was thinking of doing the same thing. I've been using the Diesel filters inside a funnel but thought about this cap thing as well. The thinking I had behind it was you could just use another cap as one gets dirty.

Looks like it fits nicely inside the Gatoraid bottle as well.

Cheers, Making this later tonight.

-Edit- What did you use to drill the hole? Just a big bit? I think the largest I have is an inch.. thinking that should do.

Neat idea but not much surface area for filtering. How about skipping the cap and using a rubber band to hold a larger piece of filter (3" circle?) around the funnel outlet. Some of the filter could thus extend past the end of the 'bottle-funnel' and might allow for faster filtering.

I drilled a pilot hole in the center of the cap, then used a stepped drill bit.

I tried using a bigger filter, wrapped around, and it did not fit into the gatorade bottle very well. It also has more water weight. It takes two minutes to pre-filter a liter with a fresh filter. It would go faster with more surface area

Ken,

I did a search for the filters but come up with only filter bags. Where did you find the discs? or are those cut outs from filter bags?

If he's using the same bags as myself, you have to cut the filters out of the bags. It cuts fairly easy.

Thanks Corey!

I cut the disks out of a bag.
