How to choose
Match the filter to your faucet
Faucet-mount filters screw onto the tap, so fit comes first. Count the adapters in the box: the BLINGARTY holds 13 adapter types, the klleyna holds 22, and the ATOJET holds 9. Pull-down faucets need the klleyna style of adapter, while the BLINGARTY does not fit pull-out faucets, square spouts or induction faucets. The PCTC fits round and long basic faucets from 0.63 to 0.75 inch, so measure your faucet before ordering.
Read filter life in gallons and months
Filter life is stated two ways here: gallons per cartridge and months of use. The BLINGARTY gives 780 gallons, the klleyna gives 528 gallons or about 3 months, and the ATOJET gives 500 gallons at up to 2 months per filter. A gallon figure lets you compare cartridges directly, while a month figure depends on how much water you run through the tap. Pick the figure that matches how you plan to use the filter.
Check certification numbers before buying
NSF/ANSI numbers name the standard a filter was certified against, not a general quality mark. The ATOJET is certified to NSF/ANSI 42, and the klleyna is certified to NSF/ANSI 372. The BLINGARTY cartridge uses coconut shell carbon fiber with 13 stage filter layers. If a number matters to you, match it to the pick that carries it.
