Under Sink Water Filters
Under sink water filters give you filtered water on tap. They connect to your kitchen's cold water line. Filtered water comes out through its own tap on the bench. There's no tank to fill. No gravity needed. No clutter on your bench.
Awesome Water Filters stocks undersink systems. Choose from single-stage, twin-stage, and multi-stage models. We also stock genuine replacement cartridges.

How Does an Under Sink Water Filter Work?
An undersink filter connects to your cold water line. This sits under your sink. Water flows through one or more cartridges. Then it comes out through a tap on your bench.
What the filter removes depends on the cartridge. Common types include:
- Sediment filters
- Carbon block filters
- Fluoride-reduction filters
Benchtop filters use gravity. You fill them by hand. Undersink filters are different. They give you water on demand. No refilling needed. Flow speed depends on your system and your water pressure.
How to Choose an Under Sink Water Filter
- Number of stages. More stages means more filtering steps. A single-stage system may just target sediment or chlorine taste. A multi-stage system adds carbon and other media.
- Filter media. Carbon block filters cut chlorine taste and odour. Ceramic and KDF cartridges target other substances. Check the product page for details.
- Flow rate. Make sure the flow rate suits your household. Busy homes need a higher flow rate.
- Cartridge replacement. Most cartridges need replacing every 6–12 months. Factor this cost into your choice.
- Installation. Undersink filters need a water connection. In some states, this must be done by a licensed plumber. Check your local rules first.
Under Sink vs Benchtop vs Reverse Osmosis
All three filter your drinking water. But they work in different ways.
- Benchtop filters. No plumbing. You refill them by hand.
- Undersink filters. Water on demand. Needs installation under the sink.
- Reverse osmosis. Removes more dissolved solids. Uses a membrane plus extra filters. Needs installation. Makes some waste water.

FAQs
Do I need a plumber to install one?
Most undersink filters connect to your cold water line. In some states, a licensed plumber must do this work. Check your local rules first. Some quick-connect systems are easier to install yourself, where allowed.
How often do I replace the cartridges?
Most cartridges last 6–12 months. This depends on your water and how much you use it. Multi-stage systems may need different schedules per cartridge. Check your manual. Set a reminder.
Will it reduce chlorine taste?
Most carbon block cartridges help cut chlorine taste and odour. This depends on the cartridge's condition and your water flow. Replace cartridges on schedule to keep them working well.
Can I use it with bore or tank water?
Systems built for town water may not suit bore or tank water. This is especially true for untreated water. Get advice on the right pre-treatment for your water first.
