It would have been 5 star if the filters were wrapped individually in plastic. But Since I bought 6 and Im replacing them every 2 months then the others will be sitting around in less than sterile conditions for 2-12 months. Im using them as a predicted for a sterile lab unit so sterility is important to me.
[This review was collected as part of a promotion.] Great service, great product. Its also nice that they ship for free. Have been buying filters from this company for a few years and I never have any problems.
