Start with the water you use, the available space and the complete plan.
Choose functions you will use
Decide whether you need ambient, cold and hot water, or a model that also makes ice. Different models offer different temperatures, tank sizes and dispensing controls.
Measure the installation space
Measure width, depth and height, and leave access for power, water connections and servicing. A countertop model and a floor-standing model have different space requirements.
Read the full plan
Compare the service type, obligation period, price after any promotional period and charges for extra installation work. Ask for the exact written quotation before applying.
Start with a day in your home
Think about when people use drinking water: an early-morning rush, preparing drinks throughout the day, or frequent use of hot water for cooking. List the features you would use regularly and those that are only occasional conveniences. This helps you compare models without paying for a feature solely because it appears in an advertisement.
Compare filtered water and maintenance
Coway offers different filtration methods across its range. Ask which method a particular model uses, which filters need replacement, and whether the quotation includes the required filter service. Product descriptions are not a substitute for the model manual or advice about a specific water-quality concern.
Make a shortlist you can actually install
Measure the clear space rather than relying on a product photo. Note the location of a suitable electrical outlet and water connection, the direction a cabinet door opens, and whether a person can reach the unit for cleaning or servicing. Ask for the model-specific clearance and any additional installation charges before committing.
Compare the whole quotation
For each shortlisted model, request the same details: exact model and colour, service type, contract obligation, regular monthly price, any promotional months and the price after them, plus installation and termination terms. A monthly amount is useful only when you know what it covers and how long you are committing to it.
