What the Ninja HydraSense removes

"Certified" means a certifier (NSF, WQA, IAPMO or CSA) lists this exact product for that reduction claim; the listing is linked. "Brand test only" means Ninja cites a lab report but no certifier lists the claim. See certified vs. tested.

PFAS	Certified	IAPMO R&T listing, NSF/ANSI 53 ("Total PFAS")
Lead	Certified	IAPMO R&T listing, NSF/ANSI 53 ("Lead")

What it costs to run

Yearly cost = replacements per year × filter price, for each filter it uses; a filter is replaced at its gallon rating or its month limit, whichever comes first. Water use: drinking and cooking water (0.28 gallons per person a day, EPA's average adult intake).

Household	Gallons a year	Filters a year	Total a year	Per gallon
1 person	102	$80	$80	78¢
2 people	204	$80	$80	39¢
4 people	409	$136	$136	33¢

Per-gallon costs in the table are for real use, so they also count any filter replaced at its month limit before it reaches its gallon rating. At rated filter life alone, filters cost 33¢ a gallon (the figure at the top of this page).
