Review on Diameter Lab Supply by Membrane Solutions by Hayden Hart

I can't think of anything really positive to say considering there are much better filters out there (same diameter, 0.22um, same cost). All of these filters are heavy particles. A coffee filter would do the same job. I've gone through 4 filters and still haven't gotten the same quality results as I did with 1 filter compared to the filters I normally use (which I can use multiple times if needed). I don't know why they have such high ratings to be honest. You're not filtering properly, period. It wasn't a bad one or two. I really doubt it needs to filter bacteria and other particles, dyes etc, which it should be able to do. They are unable to remove color from what I filter by 4 filters and these are larger molecules than bacteria. I've been using similar filters from different brands for about 10 years and I think these are the worst filters I've ever come across. I had to come back here and order the ones I would normally do. So waste of money, useless and potentially dangerous depending on what you use it for. The only reason I'm worried about checking them out is because for some reason they have great reviews and I've noticed some people trust them for IVDU filtering. . This is waste material. You don't get everything you think you're getting. White plastic is actually any brand much better here.
