How to choose
Filtration stages and standards
Filtration stages count the layers water passes through, and a standard number shows the test the filter meets. The PHILIPS gives 3-stage filtration with NSF-certified KDF. The Brondell is certified to NSF/ANSI 177. The MakeFit gives KDF-55 with calcium sulfite and vitamin C, the Delta reduces chlorine and sediment, and the Hotel Spa gives enriched KDF. Compare the stage count and the standard number with the contaminants you want reduced.
Size and where it fits
A small filter should add little height or bulk between the shower arm and the shower head. The Brondell is compact and 53% thinner than other shower filters, the Delta is concealed behind the shower head and limits intrusion, and the Hotel Spa is super compact and universal. The PHILIPS measures 2.4 inches by 2.4 inches by 6.85 inches, while the MakeFit is a shower head itself rather than an inline unit. Compare dimensions and fit with your shower arm and head.
Filter life and replacement
Filter life tells how long a cartridge lasts before replacement, and replacement access tells how the cartridge changes. The PHILIPS, Brondell, and Delta each give a filter life of 6 months, with the PHILIPS treating 50,000 liters and the Brondell filtering 10,000 gallons. The Delta changes in less than 2 minutes, the PHILIPS installs in 2 minutes, and the Hotel Spa replacement cartridge is sold separately. Compare life, capacity, and replacement access before choosing.
