How to choose
Filter stages and standards
Stages describe how many layers water passes through: the ATOJET uses 6 stages, with a sediment layer and a carbon core. Standards describe what a filter is certified against: the ATOJET carries NSF/ANSI 42, and the Frizzlife is certified to NSF/ANSI 372. Compare the standard, not just the stage count, when you compare two filters.
Fit, rotation and spray modes
Check the faucet connection before you buy: the Frizzlife includes 7 thread sizes, the Dexspoeny is not suitable for threadless faucets, and the CaoXiong fits most round faucets with a 2.18 cm outlet. Rotation changes where water lands: the Dexspoeny, LiXiongBao and CaoXiong rotate 360°, and the Frizzlife rotates 1080° with 2 spray modes.
Filter life and replacement
Filter life tells you how long a cartridge lasts: the ATOJET and LiXiongBao each list 500 gallons, the ATOJET filter lasts up to 2 months, and the Frizzlife replacement cycle is 30 days. The Dexspoeny set includes 18 elements, and the CaoXiong element can be replaced when it darkens. Keep spare elements on hand so a spent cartridge does not interrupt use.
