How to choose
Match the media to your water
Shower filters differ by what their cartridges hold. Sediment and carbon catch particles and chlorine, KDF and calcium sulfite target chlorine and heavy metals, and vitamin C infusion is a separate approach for chlorine. The WEAQUA and BBLIFE use calcium sulfite with carbon and KDF, the Aquabliss and Aqua Earth add vitamin C, and the IBGBYAS uses calcium sulfite, carbon fiber and KDF-55. Match the media list to what your water needs, not the stage count alone.
Compare cartridge life in months and gallons
Cartridge life is stated two ways here: months, gallons, or both. The WEAQUA and BBLIFE cartridges last 6 months, the Aquabliss lasts 3 to 6 months, the Aqua Earth lasts 3 to 6 months or up to 10,000 gallons per cartridge, and the IBGBYAS lasts 4 to 6 months or 10,000 to 12,000 gallons. A gallon figure depends on your household usage, so a month figure is easier to plan around. Check whether the box includes a spare cartridge: the Aqua Earth includes 2 cartridges for up to 1 year.
Check fit before you buy
These filters install between the shower arm and the shower head without special tools, but the details differ. The Aquabliss fits standard 1/2-inch shower arms and adds 3 to 4 inches to the arm, while the Aqua Earth fits any standard 1/2-inch shower arm and the BBLIFE fits many fixed, handheld, rainfall and combination showers. Measure your shower arm and check the thread size against the filter's fit claim, and keep the spare washers and thread seal tape from the box for the install.
