SAN-AIR V3R Air Handler Reactive Gel 500 g Refill is a replacement reactive gel pack designed to maintain ongoing microbial control within ducted HVAC systems, air handlers and large enclosed areas. As the gel slowly evaporates, it releases active compounds into the airflow to help reduce airborne mould spores, bacteria, fungi and odours - supporting fresher, healthier indoor air. This refill size is ideal for larger systems and spaces where continuous air quality enhancement is needed without harsh chemicals.
Features & Benefits:
Designed for Refills: Specifically manufactured as a replacement gel pack for SAN-AIR reactive gel housings or standalone placement.
Continuous Air Sanitisation: Gel slowly evaporates to diffuse active compounds throughout the airflow, helping minimise airborne microbes.
Improves Indoor Air Quality: Helps reduce musty and stale odours commonly associated with mould and poor ventilation.
Large Coverage: 500 g refill provides extended protection compared to smaller gel sizes.
Safe & Natural: Water-based reactive gel formulated with natural actives - non-toxic and non-corrosive.
Where to Use It:
Ducted HVAC Systems: Place in return air wells, plenums or near filters so conditioned air passes over the gel.
Air Handler Units: Excellent for larger residential or commercial HVAC systems requiring ongoing microbial control.
HVAC Ducting & Coils: Ideal for positioning near coils or within duct access points to improve airflow hygiene.
Large Indoor Areas: Office spaces, workshops, warehouses and rooms with sustained airflow from HVAC systems.
How to Use:
Unpack the Refill: Remove the gel pack from its packaging.
Activate Gel: Peel off the protective seal on the gel surface to begin slow evaporation.
Position in System: Place the gel in the reactive gel housing, return air well or near filters/coils where airflow will distribute active compounds.
Allow Continuous Action: The gel will gradually release actives into the airflow over several weeks.
Replace When Spent: Once the gel's output has diminished, replace with a fresh refill for ongoing protection.
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
