Elecrostatic air filter

I first noticed the low fuel economy and major loss of power in a rainstorm. It acted like the choke was on. Examining the air filter showed that there was water pooled in the housing. The ram air hose (which has since been replaced with clothes dryer hose) channels water in during a storm and saturates the paper air filter element.

After much head scratching, I bought a $22 electrostatic filter from Ace hardware designed for home heating units. It was disassembled and the element layers cut into strips. An old Fram filter from my car was stripped out to just the two big rubber rings and the mesh inner ring, so that what I was left with resembled a spool.

I wound the new strips on this form maintaining the original order of materials in hopes it would still have the electrostatic filtering properties.

The difference in fuel consumption was immediately noticeable, and the losses on rainy and muggy days is gone.

I examine the new filter periodically, and rinse it with a garden hose if it needs it.

did ypu just buy the element, or the whole static generator that makes those filters function? I've often wondered how much electricity those static filters draw.

I understand how they work but do they really filter all elements? I mean can that actually filter as well as a regular air cleaner.

Also you don't worry about water pooling up and going in your intake directly?

It does not use a power supply. The element I am referring to is simply layers of dissimilar plastic that generated a static charge as air passes over them. Take a look here: http://www.riteair.com/filtercat.htm?ai=00020001
The claim is it removes 97% of particles, but there is a companion spray to make the element stickier at $5. You can used Pam cooking spray.

Yes, water in the air filter housing IS a concern, but that was one heck of a storm on the freeway.

Here is another one that is 'Walmart tested'. WOW, that sounds impressive.

Cool. I wonder if there is a way to test if it is still maintaining the same properties (static cling?!?!?! Where's my electron microscope when I need it!!!!). I would think it needs to be changed out more often, but maybe not.

Any way we could see some pictures? I'm going to put a CAI on my Subaru, and adding an electrostatic filter sounds like a really neat idea.

Photo and brief tutorial

I made a little tutorial and a couple of photos here:

I really wish I had made one of these filters years ago.

Interesting idea. I wonder what the benefits are as compared to a high flow cotton gauze filter.

As far as water pooling up in the intake, it takes quite a bit of water to hydrolock an engine. In high humidity, the air being sucked in is saturated with water. An internal combustion engine is just as much a water pump as it is an air pump. However, if the filter is soaked you're not going to get much flow through it and that's generally not a good thing. Also, water present somewhere in the intake tract will occupy some portion of the available air flow volume.

Awesome! Thank you.

When I get around to making the CAI for my Subaru I'll take a long hard look at using that.
