Water Filters for Tap Water Coolers

Q: What's the difference between single and dual filters?

The single filter (F1) removes chlorine, odours and particles. The dual filter (F2) adds a second filtration stage (e.g. quartz or anti-scale) for even cleaner water, ideal for areas with hard water.

Q: How often should I replace the filter cartridges?

Replacement is recommended every 6–12 months, depending on consumption and water quality in your area.

Q: Which filter is suitable for areas with hard water?

For hard water areas, we recommend the F2-Central filter with quartz and anti-scale stages, or combining a single filter with a water softener for maximum protection.

Q: What connection do I need — 1/2" or 1"?

1/2" (Direct) filters connect directly to the tap or under-counter cooler. 1" (Central) filters are installed at the mains supply and filter all water feeding the premises.

Frequently asked questions

Can I install a filter on any mains water cooler?

Yes. Oasis filters are compatible with all classic and professional mains water coolers. Connection is via 1/2" (under counter / direct) or 1" (mains supply), depending on the model.

What's the difference between single and dual filters?

The single filter (F1) removes chlorine, odours and particles — ideal for areas with good water quality. The dual filter (F2) adds a second filtration stage (e.g. quartz or anti-scale) for even cleaner water, ideal for areas with hard water.

Replacement is recommended every 6–12 months, depending on consumption and water quality in your area. In commercial spaces with high usage, replacement may be needed sooner.
