Benchtop Water Filters
Benchtop water filters give you filtered drinking water without any plumbing. They sit on your kitchen bench, require no installation, and use gravity to draw water through multi-stage filter media — making them one of the most practical and accessible water filtration options for Australian homes, offices, caravans, and rental properties. Awesome Water Filters stocks a range of gravity-fed benchtop filter systems, along with replacement cartridges and spare parts to keep them running.

How Does a Benchtop Water Filter Work?
A gravity-fed benchtop filter typically consists of an upper chamber and a lower chamber, separated by filter cartridges. You pour water into the upper chamber — from the tap, rainwater tank, or any other source — and gravity draws it down through the filter media into the lower chamber. The filtered water then dispenses via a tap at the base of the unit. No electricity, no mains connection, no plumber required.
Filter media varies by system. Our 8-stage KDF/carbon/mineral cartridges combine multiple filter stages — including KDF, activated carbon, ceramic, mineral stones, and infrared balls — designed to help improve taste, reduce chlorine taste and odour, and add trace minerals as the water passes through. Always check the specific filtration claims in the product documentation.
Choosing the Right Benchtop Filter
Consider the following when selecting a benchtop filter:
- Capacity: Units typically range from around 8L to 20L total capacity (upper and lower chambers combined). A larger lower chamber means less frequent refilling for households that use more water.
- Filter media and stages: More stages can mean more filtration steps. Compare the specific media used and check whether any performance claims are supported by test data or certifications.
- Ceramic dome vs. sediment dome: Most gravity-fed benchtop systems include an upper ceramic or sediment dome that captures particulates before water passes to the lower filter cartridge. Ceramic domes can be cleaned and reused; check the replacement interval recommended by the manufacturer.
- Material: Units may be stainless steel or BPA-free plastic. Consider the look, weight, and long-term durability for your setting.
- Cartridge cost and availability: Replacement cartridges are an ongoing expense. Confirm that genuine or compatible replacement cartridges are available and factor in their cost.
Benchtop Filters vs. Undersink vs. Water Coolers
Benchtop gravity-fed filters suit people who want an affordable, portable, no-plumbing filtration option. They're ideal for renters, small households, offices, and caravans. If you need more volume and prefer water on demand without refilling, see our Under Sink Water Filters. If you want heating and cooling alongside filtration, explore our Freestanding Water Coolers or Benchtop Water Coolers.
Frequently Asked Questions
How often do I need to replace the filter cartridge in a benchtop system?
For 8-stage KDF/carbon cartridges, we recommend replacement every 6–12 months, or after approximately 3,000–5,000 litres — whichever comes first. If you notice a reduction in flow rate or a change in taste, replace the cartridge sooner. Ceramic dome filters should be cleaned monthly with a soft brush and replaced annually or when cleaning no longer restores flow.
Do I need to flush a new filter cartridge?
Yes. When installing a new 8-stage cartridge, flush the system by running several litres of water through it and discarding the initial output before drinking. This removes carbon fines and any manufacturing residue. Follow the instructions in your unit's user manual.
Can I use a benchtop filter with rainwater or tank water?
Gravity-fed benchtop filters are designed primarily for treated town water. Using them with rainwater, tank water, or bore water introduces additional considerations — the filter may not be designed to address microbial or chemical characteristics specific to untreated sources. Seek advice on appropriate treatment for your specific water source before use.
How long does a benchtop filter take to fill the lower chamber?
Flow rate varies by cartridge type, cartridge age, and the amount of water in the upper chamber. A new 8-stage cartridge typically produces filtered water at a moderate flow rate that slows as the cartridge ages or becomes partially loaded. Slower flow can indicate the cartridge is due for replacement.
