|I ordered 2 sets of 3 and they came in the green eggs with German, French, and Spanish writing on them.
I opened one with a utility knife with no problems. There is no writing on the filter, but it looks very good. I have been looking up filters and some say that the old filters will do nothing to protect you when they are out of date, so I'm not sure if being in the air tight eggs saved them or not? The a "ABC" on then is for atomic, biological , and chemical. I would like more info if anyone has some facts. If there are good filters, you can't beat the price, and CTD shipped out fast.|
