Magna is a Latin word which means “great,” and that is the true and accurate meaning of the US Water Magna Filter. The Magna Filter comes in two sizes: 4.5” x 10” for homes up to 3 bathrooms and 4.5” x 20” for homes with more than 3 bathrooms. This is a true commercial-grade filter.

What Makes The Magna Filter So Great?

  • Magna Seal - It has a positive “o-ring seal” unlike traditional “flat top” filters
  • Magna Media – The 20” filter has 36 square feet of pleated polyester commercial grade media – compare that to other brand pleated filters which have 30-50% less.
  • Magna Contaminant Capacity – Traps 12 times sediment depth filters, 8 times string wound filters, 2 times other pleated sediment filters.
  • Magna Made in USA – Nothing made outside of the U.S. and conforms to NSF/ANSI 61 Certified by WQA
