Rated flow and capacity apply under specified conditions, not a promise for every home. These are cold-water filters for treated drinking water, not disinfectors or water softeners. Standard numbers do not mean every contaminant is reduced. Follow the exact model’s performance sheet and replacement schedule. Capacity ratings do not apply to mechanical filtration claims.

Consider this if cabinet space is tight and a slower drinking-water tap is acceptable. Measure room to remove the housings as well as space to mount them.
WQA lists AQ-6200 with AQ-C2-R replacement filters, including lead reduction. The current performance sheet matches that pairing. Its 0.5 gpm rating is lower than the other two options here.

Replace the AQ-C2-R set at six months or rated capacity, sooner if water conditions require it. The manual calls for flushing after changes and checking connections for leaks. Allow access to twist off each housing.

Use the AQ-C3M-R set for this AQ-6300M system. Follow the six-month or capacity limit; a lightly used filter still needs scheduled replacement. Follow the manual for the reminder battery, flushing and leak checks.
