Key Specs to Compare Before Buying
-
Check Filtration Stages
Look at the filtration stages to understand what contaminants are removed. The Aquasana Claryum 2-Stage Under Sink Filter uses a two-stage process for lead and PFAS reduction. This setup targets specific impurities without stripping all minerals. If you prefer to keep essential minerals in your water, a system like the Direct Connect model may be better. It removes contaminants while preserving natural minerals. Match the stage count to your water quality needs and desired taste profile.
-
Verify Installation Type
Determine if you can modify your sink area. Under-sink units like the Claryum 2-Stage require space behind the cabinet and plumbing connections. Countertop filters like the AQ-CWM2-B need no plumbing, making them ideal for renters. Check your available space under the sink or on the counter. Ensure you are willing to drill holes for faucet mounts if choosing an under-sink model. Your choice depends on your lease terms and kitchen layout.
-
Measure Physical Dimensions
Compare the width, height, and length of the unit. The Claryum 2-Stage measures 4.25 inches wide and 9 inches tall. The Direct Connect model is taller at 20.5 inches but narrower. The Countertop filter is wider at 7.96 inches. Measure your cabinet or counter space carefully. Ensure there is enough clearance for filter changes and maintenance. Proper fit prevents installation issues and ensures easy access for future servicing.
-
Consider Weight and Space
Check the weight to ensure your surface can support it. The Claryum 2-Stage weighs 5.34 pounds. The Countertop model weighs 6.2 pounds. The Direct Connect system weighs 5 pounds. Heavier units may require secure mounting under the sink. Lighter units are easier to move for cleaning. Consider the footprint on your counter or in your cabinet. Ensure the weight distribution is stable to prevent tipping or shifting during use.
-
Review Model Specifics
Identify the exact model number for compatibility. The Claryum 2-Stage is model AQ-6200-MB in Matte Black. The Direct Connect is the AQ-MF-1 system. The Countertop filter is model AQ-CWM2-B. Different models have different filter replacements and flow rates. Verify the model number matches your desired features. Check if the color matches your kitchen decor. Ensure the model supports the specific contaminants you want to remove from your water supply.
