LG ATOM-U vs WD518AN: Water Purifier Guide Malaysia
ATOM-U moves the main purifier below the sink. WD518AN keeps the appliance on the counter. Compare both layouts before deciding which fits your kitchen.
The LG ATOM-U WU525BS puts the main purifier under the sink and leaves a separate dispensing tap above it. The WD518AN sits on the kitchen counter. That difference affects the space you use every day and the access an installer needs.
Start by opening the cabinet beneath your sink. If plumbing, drawers and cleaning supplies already fill it, an under-sink purifier needs closer planning. If your worktop is crowded but the cabinet has usable space, ATOM-U is worth considering.
Compare the exact WU525BS and WD518AN models
This comparison uses the Solid Black WU525BS and Calming Beige WD518AN listed by LG Malaysia. Both belong to LG's PuriCare Objet Collection range.
| Detail | ATOM-U WU525BS | WD518AN |
|---|---|---|
| Installation type | Under-sink main unit with separate tap | Countertop unit |
| Main unit, width × height × depth | 170 × 420 × 410mm | 168 × 398 × 400mm |
| Separate tap, diameter × height × depth | 48 × 264 × 188mm | Built into the countertop appliance |
| Hot-water settings listed | 40°C, 75°C and 85°C | 40°C, 75°C and 85°C |
| Preset dispensing volumes listed | 120, 250 and 500ml | 120, 250, 500 and 1,000ml |
These details come from LG Malaysia's WU525BS specifications and WD518AN specifications. Product dimensions describe the appliance itself. An installer must also allow for connections, ventilation and servicing.
ATOM-U frees worktop space and uses cabinet space
With the main unit below the sink, ATOM-U leaves a separate tap on the worktop. That arrangement can suit a kitchen where the preparation area is already shared with a dish rack or coffee machine.
Measure the usable cabinet interior. Include the sink bowl, waste pipe, hinges and shelves in your photos. Check that the cabinet door can close and that the proposed unit position remains accessible for maintenance.
The tap position needs its own check. Ask the installer to confirm the mounting arrangement and any proposed drilling before you agree to the work. A rented condo may require the owner's approval for changes to the sink or worktop.
WD518AN keeps the purifier within reach on the counter
The WD518AN's 168mm width is useful when comparing worktop layouts, but check its full 400mm depth too. Mark the appliance outline with removable tape. Leave space for the connections and access specified during the installation assessment.
Place the mug, bottle and jug you use beside that outline. Check the practical pouring position and access to the controls. Photograph overhead cabinets and nearby sockets so the installer can assess the whole location.
For households filling larger containers, the listed 1,000ml preset is a useful point of comparison. Match the dispensing options to your containers and routine before choosing.
Compare the complete quotation
Ask for a quotation that names the model code and finish. Confirm the installation work, any additional materials and the care arrangement.
For a subscription, compare the initial and later monthly payments across the agreed term. Check filter arrangements, service visits and the conditions that apply if you move home. Our subscription versus outright purchase guide explains how to compare the full commitment.
Frequently asked questions
Which model suits a small kitchen?
Choose according to the space you can use. ATOM-U needs room beneath the sink and a suitable tap position. WD518AN needs a workable countertop location. Send photos of both areas if you are unsure.
Can the dimensions confirm that installation will work?
They help you shortlist. The installer still needs to assess the connections, access and requirements for the exact model.
