Alexapure Pro gravity filter (Gen 2) vs Aquasana Clean Water Machine

Only the Aquasana Clean Water Machine is certified to reduce PFAS, lead, chlorine and chloramine and 4 more.

Replacement filters and water for 2 people cost about $133 a year on the Alexapure Pro gravity filter (Gen 2) and $147 on the Aquasana Clean Water Machine; they cost $280 and $400 to buy.
