New Fujitsu Air Conditioner - Best Ever
As always, another great product from The Good Guys. This air conditioner was to replace my old 20 year old Electrolux one. The features of the Fujitsu C5.0kW H6.0kW Reverse Cycle Split System are wonderful, it is very quiet, cools rapidly and has the myanywAiR Next feature which allows wifi connection to your phone to enable you to turn on your air conditioner remotely.

Bought this system for our bedroom and absolutely love it!, it’s quiet, easy to use and can put a secondary controller on your phone, which is actually easier to use than the remote control it comes with, great product!

Allergy friendliness
Good - Apple-Catechin and ion deodorisation filters help reduce dust, mould spores and odours in everyday home use

- 5.0kW Cooling Capacity: Cools medium-sized rooms effectively, making it a practical fit for spaces around 25 to 40 square metres.
- 6.0kW Heating Capacity: Delivers strong reverse cycle heating performance for comfortable winter use in everyday home spaces.
- Inverter Compressor: Adjusts output to changing room conditions to help maintain steadier comfort during operation.

- Wi-Fi Control: Lets you change settings remotely for more convenient temperature management when away from home or in another room.

Q: Will this split system suit a large open-plan living area?
A: No. Fujitsu SET-ASTH18KMTD-NXT is better suited to a medium room than a large open-plan space. In a wide area with high ceilings or multiple adjoining zones, cooling and heating will feel less even and a larger or additional unit may be needed.
Q: Is the Wi-Fi control built in or an extra add-on?
A: It uses a plug-in anywAiR Wi-Fi adaptor II rather than built-in Wi-Fi. That adaptor is included with this model, so phone control does not require a separate Wi-Fi accessory, but it still needs home network setup before remote features will work.
Q: How quiet is it for a bedroom or home office?
A: Fujitsu SET-ASTH18KMTD-NXT is rated at 46 decibels in operation, which is quiet enough for many bedrooms and home offices. It is still an active air conditioner, so fan and compressor noise will be more noticeable when the unit is working hard.
Q: Can the human sensor reduce running costs when the room is empty?
A: Yes. The human sensor adjusts operation when no movement is detected, which can cut unnecessary heating or cooling in rooms that are not being used. Savings depend on how often the room is vacant and whether timer or app scheduling is also used.
Q: Does this model filter odours and dust as well?
A: Yes. This model uses an Apple-Catechin filter and an ion deodorisation filter to help reduce airborne dust and room odours during normal operation. It is an air conditioner with filtration, not a dedicated air purifier, so results depend on runtime and airflow.
Q: What timer options does this Fujitsu split system include?
A: Fujitsu SET-ASTH18KMTD-NXT includes a 24 hour timer for scheduled start and stop times. It suits buyers who want the room conditioned before they arrive home or before bedtime, but it does not provide whole-home scheduling across multiple separate rooms.
