Perfect for bacterial testing of water samples. I have used these in class for several years, and they are of excellent quality.

Great value and works exactly as they should.
Each sterile filter is individually wrapped. The filters seem to adequately capture microbes and we haven't had any problems with the filter not properly absorbing the growth media. The gridlines are easily seen so colony counting is not a problem.

Great price
Great price for 0.45 microns sterile filters. They are individually protected for easy use.

Only unbreathable thin paper.
Paper. Not breathable. Zero filtration. I could make circles on paper, cut them out and sell them if I had no conscience. Shame on you!
