Details
Avermont Direct is an authorized Crystal Quest dealer. The 2-7/8" x 9-3/4" size works as the final stage in countertop and under-sink systems, and the 20" and Big Blue sizes go after the filtration stages in whole house cartridge systems. Actual service life depends on incoming water and usage. Crystal Quest also makes a sealed inline version for RO systems and water coolers.
