NSF/ANSI 53 Certified
Lead
>99.95%
Both soluble and particulate lead. The CDC has established no safe level of lead exposure for children.
Tested & Verified
Chlorine
>99.95%
Added by utilities to kill bacteria. Affects taste, odor, and has documented health effects through inhalation.
NSF/ANSI P473 Certified
PFOA & PFOS
Certified
Forever chemicals that do not break down in the human body. Independently certified removal, not just a claim.
Tested & Verified
Chloramine
>99.95%
Used by some utilities as an alternative to chlorine. Requires specific carbon media — PALADIN delivers both.
NSF/ANSI 53 Certified
Giardia & Crypto Cysts
>99.95%
Chlorine-resistant microbial cysts. PALADIN removes both at the 0.5-micron level.
Tested & Verified
Taste & Odor
