Overview
Aquasana's Claryum Direct Connect is an under sink carbon filter that taps the cold water line feeding your existing faucet, so no extra faucet or countertop hole is needed. Water passes through one compact cartridge before reaching the tap.
Certified contaminant reduction from a single compact cartridge, with no extra faucet or countertop hole, makes this an easy upgrade for renters and homeowners. Minerals and dissolved solids pass through, so it will not help with scale or hardness.
Who it's for
Renters and homeowners who want filtered drinking water without a second faucet or a drilled counter get a simple install. Households wanting lower dissolved solids or softer water need a different system.
Pros and cons
- Uses existing faucet, no drilling
- Certified to NSF/ANSI 42, 53 and 401
- Retains calcium, magnesium and potassium
- Reduces lead, PFAS, chlorine and odor
- Does not reduce TDS
- Hard water may need an added pre-filter
- Needs clearance below for filter changes
- Change interval in months not listed
Performance notes
Filtration works by pushing cold water through a carbon cartridge, so cartridge age governs how much gets removed. Hard water can load the filter faster and slow the flow, which is why Aquasana suggests a pre-filter there. Because minerals pass through, taste changes come from removed chlorine and odors, not softening.

Frequently asked questions
How do I change the filter on the Aquasana AQ-MF-1?
Leave at least 3 inches of clearance under the unit so the cartridge can come out. The listing rates the filter by gallons but does not give a change interval in months.
Does the Aquasana AQ-MF-1 soften water or reduce TDS?
No. It retains naturally occurring minerals and does not reduce TDS. For hard water, Aquasana suggests a system with a pre-filter to help maintain flow and filter performance.
Do I need a separate faucet for the Aquasana AQ-MF-1?
No. It connects to any cold water line and feeds your existing faucet, with no countertop drilling.
What is in the Aquasana AQ-MF-1 box?
The system, a filter and an install kit with the parts needed for 3/8 inch installations.
