The OG Air Refiner
Smoke Grey is between batches. Every sleeve is handmade in West Ipswich and the next run is already underway. Be first to know when it's back, or Daintree Green and Outback Orange are ready to ship today.
The OG is 21Captains' flagship Air Refiner, designed to naturally absorb excess moisture and neutralise odours in larger enclosed spaces. No power, no refills, no ongoing maintenance. It works quietly in the background for up to two years, then sun bakes back to full capacity.
Anywhere moisture and odour are a problem. The OG works in bedrooms, living spaces, walk-in robes, bathrooms, fridges and cupboards at home, and in caravans, rooftop tents, swags, 4WDs and boats out on the road or water.
Both Air Refiners do the same job. They absorb moisture and neutralise odours naturally using activated charcoal. The difference is size and coverage.
The OG Air Refiner is our original. Bigger, chunkier, and built for larger spaces. Think caravans, boat cabins, bedrooms, living areas, and anywhere that needs serious coverage. One OG covers approximately 15 to 20m² under normal conditions.
The Slim Air Refiner is built for tighter spaces. Narrower profile, designed to slide into drawers, wardrobes, shoe racks, fridges, canopy drawers, and anywhere the OG would not fit. Each Slim covers up to approximately 10m². Two Slims together roughly equal one OG.
Still not sure? A good rule of thumb is this. If you can see the space clearly and it is an open room or cabin, go the OG. If you are targeting a specific enclosed spot like a drawer or a boot of a car, go the Slim. Many customers end up with both.
Covers approximately 15 to 20m² for general filtration under normal humidity conditions. For larger areas or high-moisture spaces, two OGs or an OG plus Slims is the right call.
Once a month, place your OG Air Refiner in direct sunlight for 1 to 2 hours. The sun's energy purges what the charcoal has been holding, restoring full absorbing capacity. Then place it back where you need it. No refills, ever.
Filled with high-quality coconut-shell activated charcoal. The outer fabric is made from recycled post-consumer plastic bottles. Every Air Refiner is handmade in our West Ipswich warehouse.
Flat rate $12 shipping Australia-wide. Orders placed before 11am AEST are dispatched same day. 30-day money back guarantee, no questions asked.
No brackets, no batteries, no installation. The OG works flat or hanging, wherever you need it most.
Millions of microscopic charcoal pores draw in moisture and trap odours as air circulates around your space.
Monthly sunlight session purges what the charcoal has been holding. No refills. No consumables. Up to two years.
WHEREVER
THE JOURNEY TAKES YOU.
The OG is built for real conditions, dusty outback tracks, coastal humidity, fridges that see serious use.
REVIEWS.
I bought 2 of the OG refiners, I hang them from the roof inside my caravan. One inside my shower and one just outside the shower. I no longer have any steam marks on the roof or musk water smell after the caravan has been closed on a hot day. I absolutely love them.
I’m really impressed with the 21 Captains product—it genuinely does what it claims to do. As someone who values both function and sustainability, I appreciate that it’s Australian-made and uses natural granular activated charcoal to effectively remove odours and moisture. You can tell it’s high quality from the moment you open the package.
I’ve used it in the home, our caravan, and even on the boat—and it performs beautifully in all settings. My nose especially appreciates the refined, clean scent it helps maintain. The design is smart and stylish too, which means it doesn’t need to be hidden away.
A great multipurpose solution that’s practical, eco-friendly, and beautifully made. Highly recommended.
My family and I have bought multiple of these works a treat we have just started our lap and have hit bad weather near Coffs Harbour and these have helped heaps
Our cat tends to make a bit of mess going to her litter. With the QLD heat, her litter area tends to smell quite a bit. We went with a 21Captains Air Refiner and holy smokes! The odour was gone within an hour!! Couldn’t recommend this product more! Great product from an Australian company owned by great Australians! What’s not to like?
We have had the 21Captains bag in our bathrooms for roughly 2 weeks now & can already tell the difference! We have drain issues in the ensuite which usually leads to bad smells, since having the bag in there we can barely notice it if at all! The kids bathroom is also smelling better too! 100% recommend this product!
These caught my eye at manly west markets. I decided to give them a go and l have to say they fantastic. I have doggys at home and l put one beside there bed.And well what a surprise l don't have doggy smells any more. I would like to say how fantastic this product is
I highly recommend this product.
We brought our 21Captains at last year's camping show and took them home. We had been having issues with mould and mildew on a dry-as a-bone and our fridge. We place our 21Captains in their respective areas and let them be. We check on them when we are near them and yep they look like they are doing a fantastic job. Off to the show today ran into the distributors and low and behold remember there was a step we forgot bring them out and place them into the sun once a month. Just goes to show the power of charcoal. Well down 21Captains worth every penny.
An awesome trendy, new way to play, a non toxic lifestyle with these air purifying bags! Totally excited to have them playing in the wardrobe and car! (Also have one just playing in the bedroom)
Thanks team for the amazing contribution you bring to the life playground!
My family and I live in a 100 year old house, so heating, efficient ventilation and correct north facing housing wasn’t much of a thing back in the 1920s. For that we suffer with condensation in certain areas of the house. Thanks to these tiny little beauties, the natural condensation is kept at bay
Great thinking from the team at 21 captains.
Also mine is grabbing some sun time while we can.
Love it! So happy to have a non toxic option. No mess, no waste, eco friendly, rechargeable, and look quite cool (unlike the toxic plastic options!)
Am converted!
Purchased for our caravan, works really well, arrived quickly and looks great. Highly recommend
It has only been a few weeks since I first purchased a couple of slim units. I then have purchased a couple of the OG units as I was happy with how the others were performing. I now have one slim in the fridge and another in a cupboard of my motor home. The two OG units I have placed either end if my living area, and have done away with the traditional bulky moisture absorbers. So far I couldn’t be happier. Not only do they absorb moisture, but they blend in well with the decor in my van. I will be buying more slims in the future as I would like to place more in cupboards and other areas of my van.
Works so well, I love it
Thank you
Works good
I was a little skeptical as it sounds to simple… but after a couple days I noticed the difference in my home. We have an old house and when it’s all shut up it gets an awful “musty” smell. Since hanging a few of these around there is barely any smell!
Just recently started traveling in our van and love how well it works keeping the van feel fresh and odour free. Has Travelling chaos’s tick of approval!
I got a couple of the OG bags and put them out in my humid lounge room. It brought the humidity down about 5-10% instantly which means my house is more comfortable to live in. I now need to buy more for the other areas of my home.
Hi Team,
I believe the Air Refiners are working well as they are quite damp & cold when I have to take them out in the sun and come back in feeling warm & dry. I also have to do this more than once per month. The reason being we live in an old Millhouse that is 5ft off the ground so there is plenty of moisture coming from underneath the house, hence why I have to take them into the sun more often. The only downside that I feel worth stating is that I wish the bags were bigger! Otherwise, I am very happy with the product itself and love that they are pet friendly. I will purchase more in the near future. Thank you.
For such a small item, this is v effective in its use.
Does exactly as advertised.
I am using them in our cabin and in the caravan, they are working well. There is no more musty smell in the caravan. I'm so happy with them that I am buying more for our cars and the tractor.
I think they would also make great christmas gifts.
I love 21 Captains and will be purchasing some more soon.
I bought them mainly to absorb moisture but found they are great at keeping the air smelling fresh.
I’ve purchased 3 lots now and recommended to others.
We have used this in both our unit and motorhome and they do a fantastic job.
Great product, does exactly what they say.
After reading all the positive reviews, I decided to purchase an air refiner for our campervan. I have to say, there are no smells - no mustiness or stale air. I am very impressed!
Wow -dog smells in the bedroom and car are gone..and no condensation in our roof top tent..going to try it in the pantry next to soak up mouse smells 😀
