Product Introduction
Formaldehyde (HCHO) is a colorless, pungent gas and a known human carcinogen, widely found in new building materials, furniture, and industrial adhesives. Traditional air filters merely trap particles, and standard carbon often reaches its saturation point for formaldehyde very quickly. At Nantong Lyusen, we have pioneered advanced Formaldehyde Decomposition technology that goes beyond simple capture. Instead of just "storing" the formaldehyde, our specialized filters utilize a chemical neutralization process (chemisorption) or catalytic oxidation to break the HCHO molecules down into harmless substances like Carbon Dioxide (CO2) and Water vapor (H2O). This "Destructive Filtration" approach ensures that the formaldehyde is permanently removed from the environment, with zero risk of "desorption" or secondary pollution. This is the gold standard for high-end residential air purifiers, hospital sterilization units, and newly renovated office spaces where long-term off-gassing is a serious health concern.
Our formaldehyde removal media is manufactured using a multi-stage impregnation process. We take high-activity coconut shell carbon or honeycomb substrates and "load" them with specialized amino-reagents or manganese-based catalysts. These agents are specifically chosen for their high reactivity with the aldehyde group. When an HCHO molecule enters the filter, it undergoes a rapid chemical reaction on the surface of the media, becoming a stable, non-volatile compound. Because this process is chemical rather than just physical, our filters maintain high efficiency even at high temperatures and low concentrations—conditions where standard carbon filters often fail. As a specialized manufacturer, Nantong Lyusen provides these materials in various forms, including granular beds, pleated panels, and "Cold Catalyst" modules. By integrating our formaldehyde decomposition technology, you are providing a proactive health solution that offers measurable, long-term protection against one of the most persistent and dangerous indoor air pollutants in the world today.
Detailed Technical Specifications
The performance of a formaldehyde removal filter is defined by its Removal Efficiency (%) and its Total Adsorption Capacity (mg/g). At Nantong Lyusen, we provide precise technical data based on the GB/T 18883 and ISO standards, ensuring that our clients can verify the CADR (Clean Air Delivery Rate) for formaldehyde in their specific device designs. We utilize "Gas Chamber Testing" to measure the decline in HCHO concentration over time, providing you with a real-world performance curve.

Every batch of our formaldehyde-removing media is tested for "Dusting" and "Odorless Operation," ensuring that the filter itself does not release any chemical smells into the room. We also offer Color-Indicator Technology for our permanganate-based media, which changes color from purple to brown as it becomes exhausted, providing a visual cue for maintenance. By providing this level of technical transparency and customization, Nantong Lyusen empowers you to build air purification products that are not just "efficient," but "verifiably safe" for the most sensitive users.
Primary Industrial Applications
Formaldehyde Decomposition technology is essential in the Furniture and Interior Design Industry. Newly manufactured cabinets, flooring, and upholstery can release formaldehyde for several years. Our filters are used in high-end air purifiers and "Smart Home" ventilation systems specifically to combat this long-term off-gassing. By providing a filter that actively decomposes HCHO, these brands can offer a "New Home Health Guarantee," giving peace of mind to families moving into newly renovated spaces. Similarly, in Schools and Daycare Centers, where air quality directly impacts the health and cognitive development of children, our formaldehyde-removing modules provide a critical layer of protection against the gases released by classroom furniture and building materials.
In the Industrial and Medical sectors, this technology is vital for protecting workers in high-exposure environments. Formaldehyde is widely used in Histology and Pathology Labs for tissue preservation; our specialized exhaust filters and fume hoods utilize decomposition media to ensure that lab personnel are not exposed to toxic concentrations of the gas. Similarly, in the Textile and Leather manufacturing industries, where formaldehyde-based resins are used for finishing, our large-scale industrial scrubbers ensure that factory emissions are chemically neutralized before being released into the atmosphere, helping companies comply with international labor and environmental safety standards.
Furthermore, our decomposition filters are widely used in Automotive Cabin Air Purification. As cars become more airtight, the concentration of formaldehyde released from interior leather, glue, and plastics can build up to dangerous levels. Our compact, high-efficiency honeycomb modules are integrated into the vehicle’s HVAC system to decompose these gases in real-time, ensuring a safe and fresh environment for drivers and passengers. We also serve the Public Transportation and Aviation sectors, providing large-scale air cleaning solutions for subway cars and aircraft cabins where maintaining a VOC-free environment is a premium requirement. From the home to the hospital to the highway, Nantong Lyusen’s formaldehyde decomposition technology provides the advanced chemical engineering needed to eliminate one of the world's most pervasive indoor toxins.
Core Technical Advantages
The standout advantage of Lyusen’s Formaldehyde Decomposition technology is the Permanent Chemical Transformation of the pollutant. Traditional carbon filters act like a sponge; they can only hold so much before they are "full," and in hot weather, they can actually release the trapped formaldehyde back into the air (desorption). Our decomposition filters, however, act like a chemical reactor. By utilizing amino-reagents or metal-oxide catalysts, we convert the formaldehyde into stable, non-volatile compounds that cannot be released back into the air. This "Zero-Desorption" guarantee is critical for high-stakes environments like hospital wards or bedrooms, where consistent air purity is a non-negotiable health requirement.
Another major technical benefit is our High Specificity and Efficiency at Low Concentrations. Formaldehyde is often dangerous even at very low concentrations (below 0.1 ppm) that standard carbon might ignore. Our impregnated agents have a high chemical affinity for HCHO molecules, "reaching out" to capture and neutralize them even when they are sparsely distributed in the air stream. This ensures that your air purifier or HVAC system can achieve the "Gold Standard" of formaldehyde removal, bringing indoor levels down to near-zero. Furthermore, our Catalytic Oxidation modules (like Cold Catalyst) do not get "used up" in the same way as carbon. The catalyst facilitates the reaction but isn't consumed, allowing for a service life that can be 2 to 3 times longer than traditional chemical filters, significantly reducing the Total Cost of Ownership (TCO) for the end-user.
Finally, Lyusen offers Odor-Free and Eco-Friendly Material Science. Some low-quality formaldehyde filters use reagents that release an unpleasant "chemical smell" of their own. At Nantong Lyusen, we use high-purity, low-odor impregnated agents and rigorous "Pre-Curing" processes to ensure that our filters are completely neutral. Our materials are also RoHS and REACH compliant, ensuring they are free from harmful heavy metals or toxic additives. For the international market, this means our filters are "Regulatory-Ready" for any jurisdiction, from California to the European Union. By choosing Nantong Lyusen, you are partnering with a manufacturer that combines cutting-edge molecular chemistry with user-centric design, providing a formaldehyde removal solution that is as safe for the user as it is effective against the pollutant. This technological edge allows our partners to market their products as "Professional Grade" health solutions, commanding a premium in the global air purification market.

Logistically, formaldehyde-removing media is a "High-Sensitivity" product. The active chemical reagents can react with moisture or urban odors if exposed to the air during transit, which would deplete the filter’s capacity before it reaches the customer. To prevent this, we utilize Airtight, Triple-Layer Moisture-Proof Packaging. Each module or bag of media is sealed in a heavy-duty inner PE liner, followed by a high-barrier aluminum foil layer, and finally an outer reinforced corrugated box or "Super Sack." This "Triple-Guard" system ensures that the media remains at 100% activity upon arrival. Our factory is located near the Port of Shanghai, providing daily access to global shipping lanes and competitive freight rates. For urgent medical R&D or replacement requirements, we offer rapid air freight via FedEx, DHL, or UPS. Every shipment is accompanied by a Batch Performance Report and MSDS, ensuring your logistics and safety teams have all the technical data they need for a smooth and tax-efficient import process. With real-time tracking and dedicated export coordinators, Nantong Lyusen ensures your specialized formaldehyde filters arrive fresh, effective, and ready to protect.
- Q: How is "Formaldehyde Decomposition" different from "Activated Carbon Adsorption"?
- A: Standard carbon works like a sponge (physical adsorption); it traps the gas in its pores but doesn't change it. Decomposition (chemisorption) involves a chemical reaction that permanently breaks the gas molecule down into CO2 and water. This is much more effective for long-term removal and prevents the "leakage" of the gas back into the room if the filter gets warm.
- Q: Does the "Formaldehyde Decomposition" filter work against other odors too?
- A: While these filters are specifically engineered for HCHO, the high-activity carbon base we use also provides excellent broad-spectrum adsorption for many other household and industrial VOCs. However, for specialized odors like ammonia or sulfur, we recommend a "Multi-Stage" filter that combines our formaldehyde decomposition media with other specialized impregnated carbons.
- Q: Is the chemical reagent in the filter safe for children and pets?
- A: Yes. Our reagents are securely bonded to the carbon or honeycomb substrate and do not "evaporate" into the air. They are non-toxic, non-volatile, and comply with strict international safety standards like RoHS and REACH. The filter is designed to keep the room safe by removing dangerous gases, without adding any chemicals of its own to the air stream.
- Q: How often should I replace my formaldehyde filter in a newly renovated office?
- A: In a high-exposure environment like a new office with lots of new furniture, we recommend replacing the filter every 6 to 9 months. While our catalysts last longer, the pre-filtering layers will eventually become dusty. Regular replacement ensures the chemical reaction sites remain accessible to the formaldehyde molecules, providing the highest level of protection for your employees.
