Replacement air filter for Subaru Forester

[Michael Pender]

I have a 2003. Took mine out to check for obstruction, and I found
quite a bit of dirt and a few leave fragments. Couldn't find one at
local stores, and didn't feel like running out to dealership... so..
Rather than buy a new one, I vacuumed both sides, ran hot water
through element (with a bit of OxyClean for good measure!). Seemed
find structurally.. and good as new...so just put it back in. Sticky
stuff? Maybe I should have sprayed it with Endust?? Plan on checking
again next year.

I have a 2003 also but I wanted better air filtration than the standard
filters because of the air quality here in the Washington D.C. Metro area.

Anyhow, I made my own three-phase electrostatic filter from scratch. Its
not hard to do and it works *really* well--maybe too well; it actually took
out the "new car" smell.

As a side benefit, the electrostatic filter is a 'permanent' filter -- it is
*designed* to be rinsed and reused. That is, a person only buys one per
car, ever.

If there is any interest I could post construction plans.

I too want to see the plans: My 2000 forester filter went to the garbage at
15,000 miles. Factory replacement was about 40 dollars so I used a hi-grade
house filter cut to best-fit? Your idea seems great. My forester OEM filter
could not be washed as it would completely clog so I could only blow it out
with my air compressor at ~ 100 psig. Eddie

I'm not really ready to post the plans yet--its going to take a while to
write it up in detail. However, I am willing to make a few more filters for
people. I'll need the dimensions of the cabin air filter in your car unless
its also a 2003 Subaru Forester. Also, please send me a picture of your old
filter if you can.

But what kind of price are you talking?

on a 2003 Forster that is.

Materials to make the prototype cost approximately $35 in parts; it would be
cheaper to make more than one at a time because much of the material
otherwise goes to waste.

I've actually recieved a *lot* of requests already, and I'm not sure I want
to get into the business of making filters for people. Instead I will
probably offer detailed plans for sale via the web. Then people could
download the plans and make their own filters.

I may reconsider selling the filters if I can find a commercial supplier
willing to assemble and ship the filters.

Kits/plans may be just as good. Also , if making these, or even
assembling /packaging kits, is not too tricky, there are often
Lighthouse for the Blind and other organizations that are despaerate for
work which can be done by disabled/challenged individuals. A guy I work
with had some small items packaged by a group like that.
fyi
