10L Oxygen Can with Spray Cap

What Is a Portable Oxygen Can and How Can It Help You?

Feeling short of breath after a tough workout, a long hike, or a stressful day? You're not alone. The portable oxygen can from Clear O2 is a convenient, over-the-counter inhalation product designed to deliver a burst of supplemental oxygen whenever you need it most. Each 10-litre canister comes fitted with an easy-to-use spray cap, making it straightforward to use at home, at the gym, or on the go — no prescription required. At just £13.49, it's an accessible option for anyone looking to support their breathing during everyday activities or recovery.

Oxygen makes up roughly 21% of the air we breathe under normal conditions. During intense physical exertion, illness, or exposure to high altitudes, your body's demand for oxygen can temporarily outpace supply. That's where a supplemental oxygen canister can step in. It's worth noting, however, that this product is intended for occasional, short-term use and is not a substitute for medically prescribed oxygen therapy. If you have a diagnosed respiratory condition, always speak to your GP before using any supplemental oxygen product. You might also find it useful to browse our first aid range for other products that support your wellbeing.

How Does the Clear O2 Oxygen Can Work?

The mechanism is refreshingly simple. When you press the valve and inhale through the spray cap, the canister releases a concentrated stream of oxygen directly into your airways. This temporarily raises the partial pressure of oxygen in your lungs, which supports more efficient gas exchange across the alveolar membrane — the tiny air sacs where oxygen passes into your bloodstream.

• Press the spray cap valve to release oxygen
• Inhale slowly and deeply through your mouth
• Oxygen travels through the trachea into the bronchial tree
• Gas exchange occurs at the alveoli, increasing blood oxygen saturation temporarily
• Repeat inhalations as needed, following label guidance

The effect is short-lived — typically lasting a few minutes — which is why this product is best used situationally rather than continuously. Think of it as a quick top-up rather than a long-term solution.

Who Should Use the Clear O2 10L Oxygen Can?

This product is designed for adults and older children who experience temporary breathlessness or fatigue in specific situations. It is not intended for people with chronic respiratory conditions such as COPD or severe asthma, who require medically supervised oxygen therapy. Always consult a healthcare professional if you are unsure whether this product is appropriate for you.

• Athletes and fitness enthusiasts seeking post-exercise recovery support
• Travellers visiting high-altitude destinations where air is thinner
• People experiencing temporary fatigue or mild breathlessness
• Those wanting a portable, on-demand breathing aid for occasional use

How Does the Clear O2 Can Compare to Other Oxygen Products?

Is the Clear O2 Oxygen Can Safe to Store at Home?

Yes, provided you follow the storage instructions carefully. The canister is pressurised, so it must be kept away from heat sources, open flames, and direct sunlight. Store it upright at room temperature — ideally between 5°C and 25°C — and keep it out of reach of children. Never puncture or incinerate the canister, even when empty.

Because this is a pressurised product, it should not be stored in a car on a hot day or near a radiator. If you're travelling with it, check airline regulations before packing it in your luggage. For those managing ongoing health conditions, our vitamins and supplements range may also offer complementary support for energy and respiratory health.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Is the Clear O2 Oxygen Can and What Is It Used For?

The Clear O2 10L Oxygen Can with Spray Cap is a pressurised canister containing concentrated oxygen for inhalation. It is intended for supplemental use — meaning it provides a short-term boost of oxygen rather than replacing the air you breathe normally. People use it to help manage temporary breathlessness, support recovery after physical exertion, or cope with reduced oxygen availability at altitude. It is an over-the-counter product and does not require a prescription.

It is important to understand that this product is not a medical treatment for any diagnosed condition. The NHS provides medically supervised oxygen therapy for people with conditions such as chronic obstructive pulmonary disease (COPD), severe asthma, or heart failure — and that is an entirely different clinical pathway. This canister is for healthy individuals seeking occasional, situational respiratory support.

What Do You Need to Know Before Using the Clear O2 Oxygen Can?

Before using this product, read the following contraindications and warnings carefully:

• Do not use as a substitute for prescribed medical oxygen therapy
• Do not use near open flames, sparks, or heat sources — oxygen accelerates combustion
• Do not use if the canister is damaged, dented, or the valve appears faulty
• Do not use in an enclosed, unventilated space
• Keep out of reach of children under 12 years
• If you have a diagnosed respiratory or cardiovascular condition, consult your GP before use
• Do not exceed the recommended number of inhalations per session
• Pregnant or breastfeeding? Speak to your midwife or GP before using any supplemental oxygen product

Regarding drug interactions, no clinically significant interactions have been identified for occasional supplemental inhalation oxygen use in healthy individuals. However:

• People taking bleomycin (a chemotherapy agent) should avoid supplemental oxygen unless directed by their oncologist, as high oxygen concentrations may increase pulmonary toxicity risk
• If you are on any prescribed respiratory medication, always check with your pharmacist first

How Should You Use the Clear O2 Oxygen Can?

Using the canister correctly ensures you get the most benefit while staying safe. Follow these steps each time:

1. Remove the protective cap from the spray nozzle
2. Hold the canister upright with the nozzle pointing towards your mouth
3. Place the nozzle close to — but not inside — your mouth
4. Press the valve firmly and inhale slowly and deeply at the same time
5. Hold the breath briefly, then exhale normally
6. Repeat for 1 to 3 inhalations as needed
7. Replace the cap after use and store upright

What Are the Possible Side Effects of the Clear O2 Oxygen Can?

When used as directed, side effects are uncommon. However, as with any inhalation product, some people may notice mild effects — particularly if they use more than the recommended amount. If you experience any persistent or concerning symptoms, stop use and speak to a pharmacist or GP. You can also browse our ear, nose and throat range for products that support respiratory comfort.

Common side effects (may affect some users):

• Mild dizziness or light-headedness, particularly if used too rapidly
• Dry mouth or throat after inhalation
• Slight headache if used excessively

Less common side effects (rare with correct use):

• Nausea, particularly if hyperventilating during use
• Tingling in the fingers or lips — a sign of over-breathing rather than the oxygen itself
• Skin irritation around the mouth if the nozzle is held too close for extended periods

Seek immediate medical attention if you experience chest pain, severe difficulty breathing, or loss of consciousness. These are not expected effects of this product and may indicate an underlying medical emergency.

How Should You Store the Clear O2 Oxygen Can?

• Store upright at room temperature, between 5°C and 25°C
• Keep away from direct sunlight, radiators, and other heat sources
• Do not store in a vehicle on warm days — temperatures inside cars can exceed safe limits
• Keep away from open flames, sparks, and smoking areas
• Do not puncture, crush, or incinerate the canister — even when empty
• Keep out of reach and sight of children
• Do not store in a bathroom or other high-humidity environment
• Check the expiry date before use and do not use beyond it

Dispose of empty canisters responsibly in accordance with your local council's recycling guidelines for pressurised aerosol containers. If you're unsure, contact your local authority for guidance. For those managing broader health and wellness needs, our vitamins and supplements collection includes products that may support energy levels and general wellbeing alongside occasional oxygen supplementation.
