Ozone sauna buyer's guide

Buying an ozone steam sauna is a considered purchase, and the specifications are not always quoted the same way twice. This guide sets out what distinguishes our models, what the numbers on a spec sheet mean, what a room needs, and the checks worth doing before any money changes hands — on us as much as on anyone else.

Start with how the sauna will be used

Three questions decide it: who will sit in it, how many sessions a day, and which modalities you want. A home user’s requirements differ from a spa running eight sessions a day; a clinic seeing the general public differs again, because the user weight limit decides who you can turn away.

The range, and what genuinely differs

Our Standard, Deluxe and Red Light saunas share the same core: a hand-crafted fibreglass cabinet, a head-outside design, an oxygen concentrator included, an ozone specification of 47 ppm at 2 l/min from a 500 mg/h generator with 10 adjustable levels, the applicable plug for your country, plug-and-play parts, and no plumbing.

That ozone figure describes the sauna as a whole. The 47 ppm is the ozone concentration across the entire air volume inside the sauna, produced by a 500 mg/h generator on a constant 2 l/min oxygen feed — not the concentration in the delivery line, which is why it reads as a modest ambient number. It fluctuates a little with your size, build and weight. Each of the 10 levels steps the generator output by 10%, and the oxygen flow stays constant at 2 l/min. A bigger cabinet does not mean more ozone.

Across the range, our saunas take users up to about 2 m (6 ft 5 in) tall, and every model carries 12 micron far infrared. The Standard and Deluxe are three modalities in one — ozone, steam and far infrared. The Red Light is seven — ozone, steam, far infrared, near infrared, and red, blue and green light. We build them into one sauna because, in our experience, one session is easier to keep to than several appointments on separate machines, and because one unit is more practical for an outlet than several. What otherwise differs between the models is element wattage, size, seat levels and user weight limit.

Standard ozone sauna

Steam, ozone and 12 micron far infrared. 1180 mm high, 680 mm wide (1360 mm doors open), 1200 mm long, 80 kg. A 1500 W element, four adjustable seat levels, four castors, improved heat distribution under the feet, users up to 120 kg.

Deluxe ozone sauna

The same three modalities with more room: 1150 mm high, 680 mm wide (1360 mm doors open), 1400 mm long, 100 kg. Five seat levels, a 4.3-inch full colour TFT display, users up to 180 kg — 200 mm more length and a 60 kg higher limit than the Standard.

Red Light ozone sauna

Our flagship, and a genuinely different machine rather than a larger Deluxe. Seven modalities in one cabinet: visible blue, green and red light, near infrared at 850 nm from a full-body-length LED array, far infrared at 12,000 nm, ozone from the included oxygen concentrator with a dedicated disinfection cycle, and integrated high-output steam with precise temperature control. The spectrum runs from 460 nm to 12,000 nm, with no ultraviolet emission at all.

Wavelength is measured in nanometres (nm), and a micron is a thousandth of a millimetre — a thousand nanometres — so 12,000 nm far infrared and the 12 micron rating on the Standard and Deluxe are one specification in two units.

On eye protection: your head sits outside the cabinet throughout the session, away from any direct line of light, and the lights switch off the moment the doors are opened. That is why goggles are not part of our configuration.

Reading the specification sheet

Ozone output. Milligrams per hour is the total ozone produced; parts per million is a concentration, and it depends on the volume it is measured in. An output figure quoted without its flow rate, and without saying what volume the concentration refers to, cannot be compared between manufacturers.

The oxygen source. The concentrator strips nitrogen from room air using molecular sieve beds and feeds oxygen to the generator, which converts it to ozone. Unless specified otherwise, every concentrator we supply is a 5 l/min unit at 93% ±3% oxygen purity. The oxygen concentrator supplied with the sauna is a medical device in its own right. The model we currently supply is FDA-cleared and CE marked. The FDA clearance applies to the concentrator, not to the sauna. Ozone made from plain room air carries everything else in that air with it — which is what medical ozone refers to, and the specification most worth insisting on.

Far infrared micron rating. ’12 micron’ is the far infrared rating we quote; it names a band, not the emitter’s peak wavelength. A micron is a thousandth of a millimetre and a thousand nanometres, so 12 micron means 12,000 nm. Far infrared is absorbed at the skin and warms the body directly — radiant heating — rather than warming the air, which is convective. Every model in the range has it.

Element wattage. 1500 W on the Standard and Deluxe; the Red Light figure is on its product page. It determines how quickly the cabinet heats and holds temperature. It tells you nothing about ozone.

Who fits. Up to about 2 m (6 ft 5 in) tall, and up to 120 kg on the Standard or 180 kg on the Deluxe; the Red Light limit is on its product page. For a commercial buyer this often decides it.

Grade claims. We use 304 and 316 stainless steel and silicone in the gas path. A grade adjective means nothing unless the standard behind it is named, so ask us — and ask any other manufacturer — which standard a claim refers to.

What the room needs

Plan for the cabinet plus its door swing, the concentrator alongside it, and room for an operator. We recommend a minimum room of 2 m by 2 m, with 3 m by 3 m or larger ideal.

On power: the sauna and its oxygen concentrator together draw 1750 W. Power: 220 V / 10 A. For the 110 V versions (ordered from the international section): Red Light 110 V / 13.5 A; Standard and Deluxe 110 V / 11 A. The oxygen concentrator runs on its own separate socket (300–450 W). A 110 V sauna needs its own dedicated circuit. Before delivery, ask a qualified electrician to confirm that your circuit and socket can carry the sauna’s rated current continuously. A 3 kVA or larger inverter will run the pair. A generator of that size will too, but we do not recommend one because the voltage fluctuates.

Ventilation matters twice over. An open door and window clear residual ozone, and after nearly twenty years of operating these saunas we consider ordinary room ventilation sufficient; a wet-airstream ozone destructor rarely justifies its cost, because much of the ozone has reverted to oxygen by the end of a session and moisture in the cabinet converts it to hydrogen peroxide. Second, the concentrator itself needs fresh air to work properly.

Choose a level, water-tolerant floor: steam condenses at the door seals. No plumbing is required — the sauna runs from a water bottle at the back, filled with verified distilled water.

The formats that are not equivalent

Wooden saunas are not suitable for ozone: most enclose the head, and no medical oxygen source can be connected. Far infrared saunas are a different product; adding an ozone generator to one does not make it an ozone sauna and creates a real inhalation risk. Fabric tents are not a hard-shell equivalent either — ozone is a strong oxidant and it degrades fabric, and a folding frame cannot carry integrated controls, far infrared or a properly sealed neck opening. We build hard-shell fibreglass cabinets for those reasons.

Before you pay

Ask for a written quotation naming the model. Then ask, in writing: ozone output with its flow rate and the volume the concentration refers to; what the ozone is generated from; concentrator purity; the packing list; total landed cost; lead time; warranty scope and who honours it; where spare parts are held; and who services the unit. Our own position: in every market, a new sauna and its oxygen concentrator carry a two-year limited warranty for the first owner. In South Africa we assess a claim with you virtually, then either send a technician or ask for the parts tray back. Elsewhere we guide the repair by online video, and other small parts and electrician costs are for your account. Orders delivered outside South Africa include a complimentary spare-parts set, listed on your invoice, so small repairs need not wait for freight. South African orders do not include the set; we supply warranty parts directly.

Then verify the seller: contactable clients you actually call, the registered entity and a bank account in the same name, any claimed dealership confirmed with the manufacturer, a reverse image search on the photographs, and the cancellation terms read before you pay.

Finally, ask to see the certification paperwork. CE marking is a manufacturer’s declaration of conformity with European health, safety and environmental requirements — not a medical approval, and not evidence of clinical benefit. Each of our current models (Standard, Deluxe and Red Light) carries CE marking, and we can send the Declaration of Conformity for your model on request. We sell our ozone saunas as wellness equipment, not medical devices. Ask any other seller for a current Declaration of Conformity for anything sold as CE marked.
