Waterdrop King Tank Gravity Water Filter System
A 2.25-gallon stainless steel gravity filter needing neither plumbing nor power.
$260
Usability
The King Tank is Waterdrop's answer to the Berkey-style gravity filter: 2.25 gallons of stainless steel, no plumbing, no power, and WD-BB9 elements doing the work. That makes it the only unit in the range that keeps working in a power cut or off grid, which is the entire argument for buying it over an RO system at similar money. Waterdrop's own comparison table lists this configuration at $229 against the $259.99 the store actually charges, so check the price at the point of sale. The version with the stand is a separate SKU.
