How to choose the right one
-
Check installation type
Decide if you can modify your kitchen plumbing. Under-sink systems like the ROES-50X require permanent installation and space behind the cabinet. Countertop models like the RO-CTOP-C connect to standard faucets without drilling. Renters often prefer portable or countertop options to avoid damage. Ensure your sink area has enough clearance for the unit’s height and length before purchasing.
-
Match capacity to needs
Review the gallons per day rating to ensure it meets your family’s demand. The ROES-50X offers 50 GPD, which suits smaller households. If you need more water, the RO-PH90 provides 90 GPD. Higher capacity ensures you do not run out of filtered water during peak usage. Check the spec sheet for the GPD number to compare output rates directly.
-
Review filtration stages
Count the number of filters to understand the purification process. Most APEC models use five or six stages. Extra stages often add remineralization or alkaline filters. The RO-PH90 includes a dedicated alkaline filter stage. More stages may remove additional impurities. Verify the stage count in the attributes to see if the system includes post-filtration for taste improvement.
-
Assess physical dimensions
Measure your under-sink cabinet space carefully. The ROES-50X measures 17 inches high and 15.5 inches long. The RO-CTOP-C is smaller and sits on the counter. Ensure your storage tank and unit fit without blocking valves. Compare the width, height, and length specs against your available space. Compact models like the RO-CTOP-PH weigh less and take up minimal room.
-
Look for certifications
Verify safety standards for your drinking water. The ROES-50X holds WQA certification, indicating it meets specific purity standards. Certified systems undergo testing for material safety and contaminant reduction. Check the product description for any listed certifications. This ensures the system performs as advertised. Prioritize models with verified certifications for reliable water quality in your home.
