Question:
The #1product choice by Kitchens and Baths magazine, July 1995!!!! The absolute best carbon-based system on the market. Eliminates more than 100 EPA priority pollutants. Each filter treats 1,250 gallons of water. That is approximately 3.4 gallons per day for one whole year. Two models are available: the counter-top model or the Auxilary faucet model that tucks away under your sink. This product is 100% guaranteed. Filter change indicators tell you when the filter needs to be changed

Answer: I assume you have third party testing results available? Are these units registered in Iowa and other states that require it prior to sale? Remember, the fine for selling unregistered units after making the above statements, and not providing a performance data sheet, etc, is up to $40,000.00 PER UNIT.

I'm not an expert on this stuff by any means, but check out an article in the July/Aug 1992 "Eating Well Magazine," entitled, "Trickle-thru effect." This is on reverse osmosis filters, but has some info regarding all these filtration devises. It makes no difference how efficient they are if they have a holding tank on them. Some bacteria will get thru and the water is only really clean for a short while. In fact, if it sits too long it can actually be less healthy than the water before the filter!

I am sure there have been more recent articles on this problem, but I wrote this one down when I saw it recently in that old issue (work in Library) My folks have undrinkable well water and I was on the look out for info. This contamination problem is also true of bottled water purchased at stores. They are really only good for a few days. This was on the news recently. Again, I'm no expert, but I would guess filters that lead directly to faucet without a storage tank might be O:K, if you do change the filter and clean the linkages from the filter often
