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!

Not a twinge from my back since I started using it!
We had a water leak in our bathroom and a mould problem. This spray, along with fixing the roof leak, seems to have fixed the problem. We sprayed once as per instructions, and then repeated the process a few days later. We have not seen any regrowth. We also bought the Mould Gone reactive gel to absorb any remaining spores. We are very happy with the results.
I purchased these bandages for my daughters as they often go for bush walks. They were appreciative of them and have added them to the snake bite kits.
I purchased two of these for my daughters who often go bush walking. They were very grateful for them.
What I appreciate is the quick delivery of items ordered and the professional help and customer service of Allstate Health care.
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
