How It Works
21Captains Air Refiners use high-quality activated charcoal made from natural coconut shells. Through a specialised activation process, the charcoal is heated at extremely high temperatures, opening up millions of microscopic pores. These pores dramatically increase the surface area of the charcoal, allowing it to absorb moisture and odours, rather than masking them.
As air naturally circulates through your space, unwanted moisture and smells are drawn into the charcoal and trapped within its porous structure. This makes Air Refiners ideal for caravans, boats, vehicles and storage areas where condensation and damp air build up over time. With no chemicals, no liquids and no refills, they work quietly in the background for up to two years. It’s a simple, natural solution designed to perform wherever the journey takes you.
Where You Can Use 21Captains Air Refiner?
Use 21Captains Air Refiners throughout your home, van or caravan, in cars and 4x4s, on boats and around pets. Wherever moisture and odours build up, our Air Refiners help keep your space under control — at home or on the move.

Cam and Michaela, the duo behind LockednLifted, live full-time on the road exploring Australia in their Unimog. After stepping away from the 9–5 grind, they built a lifestyle around adventure, remote travel, and life outdoors — exactly where moisture and odour control actually matters.
They’ve been using 21Captains Air Refiners in their everyday setup for over a year, long before becoming ambassadors. From cupboards and fridges to storage spaces on the road, our products are part of their daily routine, not just content.
We chose Cam and Michaela because they genuinely live the lifestyle our products are designed for. Their experience, honesty, and real-world use make them the perfect ambassadors to show how 21Captains works beyond the showroom — out where it really counts.
Let customers speak for us
My plastic clog shoes pinged. I would wash the lining and within two days they would smell again. The shoes are so comfortable and good to slip and duck out to the shops or around the house yard I couldn't part with them.
I can now wear them without wondering if other ppl can smell them plus keep them in my room now. No odour after 24 hours, well done 21 Captains.
Great that I can recharge them over and over again by just using the Sun ☀️no more ongoing costs.
We have just placed ours in our new van, they look sexy and do an awesome 👌 job!
A sustainable and effective solution for absorbing unwanted moisture in our camper trailer and removing odours from the smelly kids 😂 . With a sleek design and natural materials, these air refiners deliver real results and being Australian made ! we can’t wait for our second order to arrive (gift for the in-laws)
Came across these and they sounded just great, ordered a pack of the Slim Air Refiners. They are soooo well made, and I really like how they are nice and slim to fit in spaces, or hang where you need them most. In use they work just as described, and I like how you just put them in the Sun for a while to refresh/re-charge them. Very, very happy with them, Thankyou
Very happy with the product, working very well in our caravan in North Queensland
Absolutely obsessed with the OG Air Refiner from 21Captains! 🤩 High quality, natural activated charcoal, and zero chemicals. It’s perfect for the car, the fridge, or even near the cat litter box. If you want a fresh-smelling space without the waste, this is it. We've got them in our bathrooms, in the caravan and ready to buy more for the fridges.
I was totally sceptical about how much this actually removed odours. Put in my ensuite as it has a damp smell. After about 4 days ensuite has no smell. Definitely will be recommending this product.
Awesome product and beautiful quality. Love my new green OG. Have had the Slim in my Caravan for two years.
These are just the best items we have them in our portable fridges bath room cars bedrooms and thinking of getting more for other spots in the house like wardrobes and such
Came across these slim air refiners, when they arrived, awesome quality, really like the natural design/material. The look good, they are well made - quality👍 and they Work😀👍. And the bonus is that to refresh them, you put them out in the Sun and Mother Nature replenishes and recharges them for continued use. Very happy, thankyou 21Captains
I purchased the slim quad packs for our caravan and as gifts for family livung in the humidity of Brisbane. I used one slim pouch in our fridge the other day when needing to store a dish containing raw onions - within a short space of time, no onion smell😄 Very happy with my purchase and would defunitely recommend.
I received my order very promptly and communication was excellent. I was thrilled to open up the box and see it. It was a gift for a friend for their caravan and they were thrilled with it. Will be ordering more !
