OmnipureELF 5M ELF-Series 3.5 x 10 5 Micron Carbon Block ELF Filter

Look, what you don't know about simple carbon filtration is plenty. 1 teaspoon of carbon has the same surface area as 4 football field. So I can't even imagine how many teaspoons of carbon make up a filter. What's even better is that the ELF 5 is a carbon block which forces the carbon adsorption rate to be higher than regular carbon fines like what's in a Brita filter. The Omnipure filter is what you will see at many commercial establishments because it's a no joke filter.

Fast shipping, great replacement for expensive OEM filters.

I need a regular return label I do not have a ups store by me thanks
