    Water filters installed in my 10 and 20 inch big blue filters and after watching your utube video...

    I trust when we have used the new filters my water analysis will be great and thanks for the recommendations on the Pentair Micron filters levels to install!

We're glad you found our YouTube video helpful and we hope your water analysis turns out great with the new filters. Let us know if you have any further questions or concerns. Thanks again for choosing our product!

    good filters

    this is my second order of two large filters, I like that the filters don't reduce my water pressure, they had my number in their records so I was able to reorder the same filters and they gave me free shipping, I recommend this site

    Great filters

    The filters are good quality and with high microns it helps to prolong the life of the filter, I recommend these filters stay away from Chinese brand
