Question 1

What are the filtration specs?? What particle size does it filter out?

Accepted Answer

Thanks for the question! The filtration specs and particle size do not apply to Sagan Life filters. Here's why: 
Most water filters make the filter media with holes small enough that bacteria and virus can’t pass through, like trying to put a tennis ball in a hole the size of a golf ball, it won’t pass through. Our Nano Fiber Technology is impregnated with silver which acts as a magnet,  attracting all negatively charged bacteria and virus to the filter media, regardless of the size. This makes the filter more effective and doesn’t require priming or pumping. Additionally, Sagan filters are not as fragile as other filters. Ours can drop or freeze and it won’t ruin the filter.

Hope this helps!

Question 2

is there backflush capability or replacement filters, or after 250 gallons is that it?

Accepted Answer

These purifiers should be replaced after about 250 gallons - no backflushing. The replacement filters for the XStream Straw and AquaDrum are available on Amazon  -  B07D41LCKZ
Hope this helps.
