Filter FAQ

Questions we hear
most often.

How do I know when to change my filter?

Filter #1 will count down from 3000 litres to 0, and Filter #2 will count down from 5000 litres to 0. The ionizer displays both sets of numbers on the panel. You should order your filter when it drops just below 300 litres — that gives you buffer to receive the new one before the current filter runs out.

Can I install the filter myself?

Yes — both cartridges twist in by hand, no tools needed. We include a one-page printed guide in every shipment, and you can WhatsApp us a photo if anything looks off.

Do you stock filters in Singapore?

Yes. We hold inventory locally so you don’t wait on Korean shipping. Most reorders should be delivered to your doorstep within 4 to 5 working days.

Are these genuine Prime Water filters?

Every cartridge is the original part from the Korean factory. Third-party filters can damage the electrolysis chamber and void your warranty — we strongly recommend genuine only.

What does delivery cost?

Free islandwide on filter reorders over S$ 100. Below that, a flat S$ 8 courier fee applies.
