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.
Bought 4 x slims and 2 x OGs for our 22.6 ft van.
They look so good and no more damp smells in the bathroom or cupboards.
Very happy 😊
I have had my OG refiners for a few weeks now and so far they seem to be working a treat. I love the quality and that they easy to hang and move around. I have one in every main room. Mainly got it so I could put it near one window to avoid condensation buildup and it has certainly stopped that moisture from building in that particular window. Have already been recommending them to friends and family.
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.
I have an old house that is never going to be 100% 'sealed' during rain and high humidity so these are my piece of mind items that will capture moisture and smells for me.
I didn’t get a big enough one for the linen press
We have newly purchased 21 Captains for our Troopy which has 2 fridges and a roof conversion. Had an incident where mould was present on the canvas of roof and in drawer fridge. After cleaning and using 1 in each fridge and 2 in the rooftop area, we have already noticed the difference in the fridges and so far so good with the rooftop canvas. Since we got them we have talked to multiple people that have them and raved about how good they are! Feeling much more confident about the Troopy now!
So far it seems to be working well in the bathroom, easy to recharge it (so to speak),in the sun at the start of every month and back to work it goes. Great product and looks good to. 😁
Living in a tiny house we were getting some condensation until I purchased 2 tiny grey bags they are a godsend.
Great quality. Highly recommend
Easy and convenient to use and stylish design too!
We love our 21captains OG air refiners. We have 7 and will be ordering more. No more condensation! Love that they are natural and can be recharged in the sun.
They keep our van smelling so goog
Service was good, product compact, sturdy and easy to hang
Well what can you say but amazing and a great product.
I purchased the Slim Air Refiner with the idea that I would put them in our caravan wardrobes and the toilet cassette box. I ended up putting one in our caravan fridge and it works brilliantly! I’m off to buy some more 😀
So far so good my caravan just smell fresh no odurs
Purchased the air refiners and received them last week. Have placed them in strategic places in two rooms where I had noticed there was condensation forming. Dried the areas prior to placing the refiners and so far ... no further condensation has occurred. Thank you they do appear to be working very efficiently.
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!
