Catalytic lamps (also known as Berger lamps) are beautiful, often designer lamps that purify the air while also wonderfully fragrancing the interior. They work on the principle of catalytic combustion, so they can operate even without a burning flame. Their core consists of a container with an alcohol-based refill, a catalytic stone and a cotton wick.
Catalytic lamps originated in France as early as the late 19th century with the aim of purifying hospital air of bacteria and odours, as air purifiers as we know them today did not yet exist. They were invented by pharmacist Maurice Berger, who also laid the foundations for the company Maison Berger Paris, whose lamps remain among the most popular to this day.
In the 20th century, fragrant essences and decorative bottles were added to catalytic lamps, turning them into a decorative and aromatherapeutic element for homes, offices and wellness spaces.
A catalytic reaction is a chemical reaction accelerated by a catalyst (in this case the so-called catalytic stone, which is part of the burner). The stone remains hot even after the flame is extinguished, and so-called catalytic oxidation begins to occur around it, breaking down impurities and microorganisms. As air naturally circulates through the space, catalytic oxidation gradually purifies it.
Today, the Berger lamp is a popular accessory in homes and public spaces because:
There are currently no detailed scientific studies on the effectiveness of catalytic lamps in domestic environments. However, there are tests by the brand Ashleigh & Burwood that suggest effectiveness against selected microorganisms in a laboratory environment:
| Microorganism | Description | Elimination after 30 minutes |
| Staphylococcus aureus (S. aureus) | Common skin bacterium; some strains can cause skin and wound infections | 99% |
| Escherichia coli (E. coli) bacteria | Bacteria commonly living in the intestines; some strains can cause infections and diarrhoea | 99% |
| Enterobacter aerogenes (E. aerogenes) | Bacteria found in the environment and intestines; may cause infections in immunocompromised individuals | 99% |
| Mites (D. farinae) | House dust mite; a common source of allergies | 99% |
| Stachybotrys chartarum (S. chartarum) | Toxic black mould that can form in damp spaces | 96% |
| Tobacco smoke – particles | Microscopic solid particles produced during tobacco combustion | 99.9% |
When choosing the best catalytic lamp for you, focus on the following criteria:
Refills for catalytic lamps offer plenty of options.
Choose these if you primarily want to purify the air without fragrance. Ideal for people sensitive to fragrances.
Choose your favourite fragrance according to your mood or the type of space. For example, lavender, vanilla or jasmine are suitable for relaxation, while citrus, mint or eucalyptus are ideal for stimulation. Woody and spicy scents help create a cosy home atmosphere.
Tip: If you are more sensitive to fragrances, avoid heavy perfumes and opt for gentle floral or citrus scents instead.
Catalytic lamps can have several undesirable effects if used incorrectly.
Using a catalytic lamp is simple:
Simply place the metal cap on the catalytic stone. This cuts off the oxygen supply and stops the reaction.
