Product Introduction
Cold Catalyst technology, also known as "Low-Temperature Catalyst," represents a breakthrough in passive air purification. Unlike traditional photocatalysts that require UV light to function, our cold catalyst air filters operate at room temperature through a natural catalytic oxidation process. At Nantong Lyusen, we utilize a unique formulation of various active metal oxides—such as manganese dioxide and copper oxide—anchored onto a durable substrate like aluminum honeycomb or polyurethane sponge. When gaseous pollutants like formaldehyde, benzene, and ammonia come into contact with the filter surface, the catalyst triggers a reaction with the surrounding oxygen and water vapor. This process breaks down harmful VOCs (Volatile Organic Compounds) into non-toxic Carbon Dioxide (CO2) and Water (H2O). As a high-tech enterprise certified in 2020, we have refined this technology to ensure it provides a continuous, 24-hour decontamination effect without any external energy source or light activation.
Our cold catalyst filters are particularly favored by international HVAC manufacturers and air purifier brands because of their "Install-and-Forget" simplicity. Since they do not rely on UV lamps, they produce zero ozone and have no electronic components that can fail. The catalytic agents used by Lyusen are non-volatile and are not consumed during the reaction; they simply act as a platform for the chemical breakdown of pollutants. This means that under normal indoor conditions, the filter can maintain its decomposition efficiency for up to 3 to 5 years. By sourcing directly from our Nantong factory, you are getting an industrial-grade catalyst developed in collaboration with top universities in Shanghai and Nanjing. This ensures that your finished air purification products meet the most stringent global standards for indoor air safety while providing your customers with a reliable, energy-free solution for long-term formaldehyde and odor management.

Primary Industrial Applications
Cold Catalyst Air Filters are the preferred choice for the High-End Residential Air Purifier market. Because these filters are active 24/7 without needing power or UV light, they are the ideal solution for removing formaldehyde off-gassing from new furniture, flooring, and paint in newly renovated homes. Brands that focus on "Bedroom Safety" or "Baby-Safe Environments" often use our cold catalyst modules to ensure that toxic gases are decomposed continuously, even when the purifier is in its lowest, quietest mode. The absence of ozone generation also makes it a powerful selling point for health-conscious consumers who are wary of electronic ionizers.
In the Commercial HVAC and Institutional sectors, these filters are increasingly used in schools, kindergartens, and senior living facilities. In these environments, air quality must be managed without adding secondary pollutants or increasing the maintenance burden on facilities staff. Our cold catalyst modules can be easily integrated into the return air vents of central air conditioning systems to provide a long-term chemical barrier against urban smog, VOCs from cleaning supplies, and building material emissions. Because the catalyst lasts for several years, it significantly reduces the "Total Cost of Ownership" (TCO) compared to standard carbon filters that must be replaced every few months once they become saturated.
Furthermore, we serve the Automotive and Industrial Equipment sectors. In cars, where high temperatures and restricted space are common, our cold catalyst cabin filters provide a robust defense against "New Car Smell" (VOCs) and fuel exhaust. In industrial settings, they are used as pre-treatment filters in laboratory exhaust systems and specialized storage cabinets for chemicals. We also see significant demand from the Public Infrastructure sector, specifically in the ventilation systems of airports and subway cars, where maintaining a fresh environment for thousands of commuters is a priority. From a compact desktop air cleaner to a massive city-wide ventilation project, Nantong Lyusen’s cold catalyst technology provides a versatile, reliable, and energy-efficient solution for permanent gas-phase purification.
Core Technical Advantages
The standout advantage of Lyusen’s Cold Catalyst Air Filters is their High-Efficiency Passive Decomposition. Traditional adsorption filters (like standard activated carbon) act like a sponge—they trap gases but eventually become "full." When they are full, or if the temperature rises, they can actually release the captured gases back into the room. Our cold catalyst filters act as a chemical reactor; they convert formaldehyde and other VOCs into harmless CO2 and H2O permanently. This "Zero Desorption" profile is a critical safety feature, ensuring that the filter never becomes a secondary source of pollution. This makes it the most stable and reliable chemical filtration technology available for long-term indoor air management.
Another major technical benefit is Extreme Structural Durability and Energy Efficiency. Because the catalyst is not consumed in the reaction and is firmly bonded to the substrate, it does not flake off or degrade over time. The honeycomb and reticulated sponge substrates we use provide a massive surface area with almost zero air resistance. This allows your air purification system to move more air with less fan power, directly contributing to lower noise levels and energy consumption—two of the most important factors for consumer air purifier rankings. For OEM manufacturers, this means you can achieve a higher CADR (Clean Air Delivery Rate) for formaldehyde while maintaining a slim and sleek product design.
Finally, Lyusen offers Scientific Authority and Global Compliance. As a high-tech enterprise that cooperates with famous state R&D institutions in Shanghai and Nanjing, our catalytic formulations are backed by advanced material science.

- Q: Do cold catalyst filters produce ozone or any other secondary pollutants?
- A: Absolutely not. Cold catalysts are passive chemical reactors that break down VOCs into harmless CO2 and water. Unlike electronic ionizers or ozone generators, there is no electricity involved, so there is no risk of ozone production. They are 100% safe for use in all indoor environments, including children's rooms and healthcare facilities.
- Q: How do I know when a cold catalyst filter needs to be replaced?
- A: Because the catalyst is not consumed, these filters have a very long life—often 3 to 5 years. However, in environments with high dust levels, the catalyst surface can become "masked" (covered by dust), which prevents the gas molecules from reaching the reactive sites. We recommend using a high-quality pre-filter and checking the cold catalyst module once a year. If it is dusty, it can be gently cleaned with a vacuum or compressed air.
- Q: Is there a difference between "Cold Catalyst" and "Photocatalyst"?
- A: Yes. Photocatalysts (like Nano-TiO2) require UV light to activate the oxidation process. Cold catalysts are engineered to work at room temperature using only the oxygen in the air. This makes cold catalysts more versatile for internal HVAC systems or purifiers where a UV lamp might not be present or desired.
- Q: Are these filters effective against cooking odors and pet smells?
- A: Yes, cold catalysts are excellent at breaking down a wide variety of organic gases, including those that cause pet odors and cooking smells. However, for "heavy" odor problems, we often recommend a composite filter that combines a cold catalyst layer with an activated carbon layer to provide both rapid adsorption and long-term chemical decomposition.
