I was sold on the air filter available through the Sharper Image.

You may have seen the infomercial. I didn’t buy one but if I did that is the one I would buy. On the extremely convincing infomercial they, in high-pitched robot voices, explained that you would actually save money if you bought their product. It would be unnecessary to buy replacement filter pieces required by all the other air filters on the market. You simply take a wet sponge and VOILA! “And you can see the dirt ;)” No expensive parts or waste.  
So I am sold, honest to goodness. Watch the infomercial sometime. I think it really is a good product. Plus, I think they have a 60-day return policy. Can’t lose. 🙂

> As when we published our original report, the best choice is the Friedrich C-90A, $450, the only portable with excellent performance overall. It’s also the only one that performed very well in our low-speed dust test. And its electronic precipitator–which charges incoming particles and traps them on oppositely charged collector plates–uses little energy and cuts filter costs.  
> Also consider the five other high-scoring models. The Kenmore (Sears) 83147, $300, is notable for its unusually quiet low speed and for its washable filter, which helps lower its operating cost.

I recomend getting a on-line subscription to Consumer Reports (24 bucks I think). I reference it all the time. Certainly worth the cash.
