UV air sanitiser
What is a UV air filter and air sanitiser?
It is a unit fitted inside the return air of a ducted air conditioning system. The one we install, the Fresh-Aire UV APCO-X Ultra, has two UV-C lamps that shine on the cooling coil and the air passing it, and a carbon matrix that treats the air on its way through. It works alongside your normal filter.
Every ducted system draws the air from your home back through a return air grille, through a filter and over the indoor coil. That coil is cool and damp whenever the system is cooling, which makes it a good place for mould and bacteria to grow. The UV sanitiser targets that spot and the air moving past it.
It can be added when we install a new ducted system or, in many cases, fitted to an existing one.
Benefits
What are the benefits of a UV air sanitiser?
Fewer germs in the air, a cleaner coil, fewer household odours, and a safe, low-maintenance design. UV-C light breaks down the DNA of bacteria, viruses and mould spores carried through the system so they cannot multiply, and the carbon matrix takes out odours and VOCs.
Fewer germs in the air
UV-C light breaks down the DNA of bacteria, viruses and mould spores carried through the system, so they can't multiply.
A cleaner coil
The lamps shine straight on the indoor coil, where mould and bacteria like to grow, helping keep it clean so the system runs efficiently.
Fewer odours
The carbon matrix takes out household odours and VOCs from cooking, cleaning products and paint.
Safe and simple
Zero ozone. The UV lamps are replaced about every 3 years.
Air filters
Do I still need to clean or replace my air conditioner's filter?
Yes. The filter catches dust and lint before it reaches the coil and fan; the UV sanitiser deals with germs and odours. A blocked filter cuts airflow, raises running costs and can freeze the coil, so keep it clean, and replace it when it is torn, warped or will not come clean.
- Ducted systems: the filter sits behind the return air grille in the ceiling. It swings or clips down for cleaning.
- Split systems: the filters sit behind the front panel of the indoor unit and clip out.
- Vacuum or rinse the filter and let it dry completely before refitting.
- If a filter is damaged or past cleaning, we can supply and fit a new one at your next service.
Installation
How is a UV air sanitiser installed?
Our technicians fit the unit in the return air section of your ducted system so the UV-C lamps face the coil, connect its power, and check it is working before we leave. On a new system it is fitted as part of the install; on an existing system it is a separate visit.
Before fitting a sanitiser to an older system, it is worth having the coil and fan cleaned, so the sanitiser starts with a clean system. See our rejuvenation eco clean.
Our own licensed electricians are part of the team, and all work is done by Frost Solutions staff. Call 1300 101 100 or send an enquiry with the make and model of your ducted system.
Good questions
Frequently asked questions
Does a UV air sanitiser produce ozone?
No. The Fresh-Aire UV APCO-X Ultra we install is a zero-ozone unit.
How often do the UV lamps need replacing?
About every 3 years. We can replace them for you as part of a service.
Can a UV sanitiser be added to my existing ducted system?
It is fitted in the return air of a ducted system, so in many cases it can be added to an existing system. Send us the make and model of your ducted unit and a photo of the return air grille, and we will confirm.
Is there an air sanitiser for split systems?
The UV unit we install is designed for ducted systems. Some split systems have their own air-quality features, such as Panasonic's nanoe™ X on selected models. Ask us when choosing a new split system.
Does it replace the normal air filter?
No. Your system still needs its normal return air filter to catch dust, and that filter still needs cleaning or replacing. The UV sanitiser works alongside it.

Absolutely fantastic experience with Frost Solutions! I recently had a ducted air-conditioning system installed and honestly, from the very first conversation through to the finished installation, the whole process was seamless. ... The installation itself was done to a really high standard, the team worked efficiently and left everything clean and tidy. ... Great people, great communication, great workmanship and a great result.

Couldn't recommend Frost Solutions highly enough. We recently had them install a 16kW Daikin ducted system with 8 outlets, 6 independent zones, AirTouch 5, multiple upgrades and a 5 year service plan. ... Another big positive is that Frost Solutions have their own electrical team as part of the installation. ... the entire experience was seamless.

Frost Solutions installed ducted air conditioning in my home today and I couldn't be happier. The team were professional, friendly, punctual, and down to earth. ... left the house spotless ... I also really appreciated the follow-up call from the office later in the day to check I was completely satisfied ... They're a local business with local staff, and the value was extremely competitive for the quality of service and workmanship provided.

Thanks guys For installing my Panasonic 18 kilowatt Ducted air conditioning today. The guys turned up on time and were very polite. They worked hard all day, did a great job and left the house neat and tidy. Also they were $2000 cheaper than the others. :)

A massive thanks to Frost Solutions. We got a 16kw ducted system put in with 7 zones and 9 outlets. Tyrone and the team were super friendly and very professional doing an awesome job, even helping me to keep maximum space in our roof so I could do an attic room. They also decommissioned and removed 2 of our old split systems. Could not recommend them more highly.
