SAN-AIR HVAC-R Anti-Microbial Surface Sealer Concentrate is a plant-based sealer designed to leave a long-lasting protective layer across ductwork and air handling surfaces after cleaning. Applied as a diluted mist or wipe, it inhibits mould, bacteria and biofilm from re-establishing inside the system — helping maintain clean airflow between service intervals.
Features & Benefits:
Broad-Spectrum Microbe Control: Kills up to 99.99% of mould, fungus, spores and bacteria on treated surfaces.
Long-Lasting Protection: Forms a durable anti-microbial barrier that resists biofilm regrowth between services.
Natural, Non-Harsh Ingredients: Made with SAN-AIR proprietary essential oils, purified water, silica alkaliser and natural binding agents.
Non-Corrosive & Non-Toxic: Safe on ductwork, coils and HVAC components when used as directed.
Economical Concentrate: Dilutes 1 part to 9 parts water — one 5L drum yields 50L of ready-to-use solution.
Where to Use It:
Ductwork & Air Vents: Internal duct surfaces, flexible ducting, registers, grilles and diffusers.
HVAC-R Equipment: Air handlers, fan coil units, evaporator housings and plenum chambers.
Residential Systems: Ducted air conditioning, split system housings and return air paths.
How to Use:
Shut Down the System: Turn the HVAC unit off before beginning any application work.
Clean the Surfaces: Remove dust, debris and existing microbial growth from all duct surfaces first.
Dilute the Concentrate: Mix 1 part concentrate with 9 parts water (1:9 ratio).
Apply Evenly: Spray through a fine mist sprayer, or wipe on with a clean cloth or sponge for full coverage.
Dry and Restart: Allow surfaces to dry completely before restarting the system, and reapply as part of routine maintenance.
Effectively Eliminates:
Mould & Biofilm Build-Up: Stops spores and microbial films from re-establishing on treated duct surfaces.
Airborne Bacteria & Fungus: Disrupts microbial survival and reproduction throughout the air path.
Musty, Recirculated Odours: Helps neutralise stale smells caused by contamination inside the system.

I love it! This is really working! I bought few things, use it, and waited for a results. After two month's of use I can say it, it is improved situation with mould at my household. It's less visible mould on surfaces, it doesn't reappear as soon as before. In some places like showers I used it twice and results keeps much longer and cleaner! ( just one detail, I also clean with domestos after for cleaner results, less stains from mould).
Also my kids were less sick with cold & flu during this winter and air conditioner smells great. So highly recommended!

Thanks James, great review and appreciate the pics it certainly will help future customers to see that they can do a simple mould test for air, surfaces, and water very simply.Regards Russell
Not a twinge from my back since I started using it!
Only used it for three weeks now and there is little or no mould visible. Where in the past mould would be visible over that period of time,, so for so good
The Pingi Mini 150g Moisture Absorber is a real game changer for me. I use them in the lounge room and bedroom and am very impressed with them. It only takes a few minutes to recharge them in the microwave, and they are ready to go again.
I had used a bunnings brand with no luck. This one though was amazing. My nightstand looked as if it were being claimed by nature and had a musty smell and white all over it. I cleaned as per label then polishednthe tablenand its better than new! Need to order more for other furniture! Thank you.
I also bought the ac unit but need someone to put it up for me, and I have two fan units. Looking forward to the change the create. Thank you! Deb Henry
Love it. Got this for our caravan that had been sitting vacant for 5 years before we purchased it. Had a musty smell that we couldn’t get rid of. Now it has completely disappeared. Thank you for a great product.
Had a musty smell after buying a house and come into winter using the gas ducted heating. We spent a lot of money to change the air return shute but there was still a smell. We got a pack of san-air products to put around the place and after a couple of days, the smell has gone. It is great walking into my home without being smacked in the face with the bad odour.
This is an excellent product. It may seem an odd to say, but when I open the fridge, it feels like I'm met with a breath of fresh air. Vegetables and other items are staying fresher too.
I bought this product as it has been unseasonably wet where we live and I was worried about mould. They appear to be working as haven't had any issues at all.
SAN-AIR Pet Odour Eliminator Gel 75g works well to eliminate pet odours, even if they are only subtle. I have four adorable adult cats and my visitors are always pleasantly surprised that there is no lingering smells from them
