Thesvin Ozone Removal Filter is an aluminum honeycomb catalytic filter that decomposes ozone into oxygen. It is designed for ozone-generating equipment such as high-voltage electrostatic air purifiers, large laser printers, commercial copiers, ozone sterilizers, and medical device exhausts. Thesvin manufactures it with a patented catalyst coating and offers full dimensional customisation to match your device or duct.
Fitment is where this filter proves itself. The core is an aluminum honeycomb substrate cut to the thickness you specify, so the filter drops into the same slot as the original without forcing the housing or leaving bypass gaps. Because the substrate is rigid, it holds its shape under airflow and resists deformation better than soft media, keeping the seal line straight.
Thesvin offers 100% customisation of the outer frame to your equipment dimensions. You can choose an aluminum alloy frame for structural support or sponge/EVA sealing strips to close the gap between filter and housing. These options help maintain airtightness at the interface, which matters because ozone removal depends on all air passing through the catalyst, not around it.
For OEM projects, Thesvin works from your drawing or an old part. The honeycomb can be cut to various thicknesses, and the frame and sealing profile are matched to your device. This approach is used in air purifiers, printers, copiers, and ducted ventilation systems where the filter is a drop-in component.
The filter targets ozone (O₃), a gas produced by corona discharge, UV lamps, and laser printers. The catalyst coating on the aluminum honeycomb converts ozone to pure oxygen on contact. This is a catalytic process, not simple adsorption, so the filter continues to work as long as the catalyst remains active.
Typical applications include:
Thesvin's catalyst technology is protected by Chinese invention patent ZL200710026260.6. Treated air meets the Chinese national standard for indoor ozone concentration (below 0.16 mg/m³) and the UL867 requirement (≤0.1 mg/m³) under test conditions. This helps equipment makers bring products to market with documented compliance.

Thesvin operates under IATF 16949 (certified in 2024) and ISO 9001, ISO 14001, and ISO 45001 management systems. For this filter, dimensional consistency is critical, so quality control covers incoming material inspection (IQC), in-process checks (IPQC), and outgoing inspection (OQC). Each batch is checked for frame dimensions, honeycomb thickness, and sealing strip placement before packing.
The company's CNAS-accredited laboratory can test filter efficiency, dust holding capacity, and pressure drop, and issue reports that are recognised internationally. The 50,000 m² production facility includes six clean rooms totalling 20,000 m². Products comply with REACH and RoHS environmental regulations, and compliance documents are available on request.
With over 20 years of filter manufacturing and export experience to Europe, the US, Japan, and South Korea, Thesvin supports OEM/ODM projects covering size, structure, filter media grade, frame material, logo, and packaging. The factory has developed more than 1,000 filter solutions and runs multiple automated production lines with a monthly capacity of several million pieces.
To get a quote, tell us your device model (or send a drawing or old part), the size you need, the airflow or water flow rate, the operating conditions, and the quantity. Thesvin's engineering team will confirm fitment and provide a tailored proposal. Contact us to start the conversation.
Thesvin customises the outer frame to your equipment dimensions, so the filter is made to fit your unit rather than adapted from a stock size. Provide a drawing or an old part, and the honeycomb thickness, frame, and sealing strip are matched accordingly. This approach ensures proper fit and airtightness.
Yes. An old part is often the clearest reference for fitment. Thesvin can measure it and produce a replacement that matches the original dimensions and interface. If you have a drawing as well, send both for verification.
Under standard test conditions, the filter achieves over 95% ozone removal efficiency. Expected life is typically 12–18 months in commercial HVAC applications, depending on ozone concentration, airflow, and humidity. Thesvin's CNAS laboratory can provide test reports for validation.
Yes. Standard-size samples are usually available free of charge, with freight paid by the customer. Custom samples carry a development fee, which can be credited against a bulk order. Samples help verify fit and performance before you commit.
Standard sizes typically have an MOQ of 500–1,000 pieces; custom sizes are usually 1,000 pieces or more, depending on configuration. Lead time for standard stock is 7–10 days, while custom orders take about 10–15 days for samples and 25–35 days for bulk production.
Please provide your device model, a drawing or old part, the size, airflow rate, operating conditions (ozone concentration, temperature, humidity), and the quantity you plan to order. With these details, Thesvin can recommend the right configuration and send a quotation.
Replacement is typically needed every 12–18 months in commercial HVAC systems, but actual life depends on ozone load and operating conditions. A noticeable increase in ozone smell or a drop in performance may indicate the catalyst is nearing the end of its service life. Regular inspection helps determine the right interval.
Yes. Thesvin offers 100% customisation of the outer frame, including aluminum alloy frames and sponge/EVA sealing strips. Honeycomb thickness can be cut to your specification. This flexibility allows the filter to integrate smoothly into your device or duct.
