I have been using that company for a number of years now and have always had great luck with their filters and housings. I had gotten a filter from Company A and it was a great filter, but cost about 4 times as much. I said their has to be a cheaper place, so I took the number off the filter and searched away. I found this company and got a number of filters for the same price as 1 from Company A. I got a variety and I can course filter, fine filter and almost sterile filter with the .45 micron one. 3 times the money and it is a papery filter, but it works well. When Wade asked me what I use, I sent him there.
