The High Efficiency Gas phase Filter （HEF）delivers exceptional performance in ultra-high-efficiency removal of chemical gas pollution and odor elimination applications.Today, an increasing number of facility and process engineers are becoming more sensitive to low-level airborne molecular contamination (AMC), where gas concentrations are typically only parts per million (ppm) or lower.The HEF Box-Type Mini-Pleat Chemical Filter effectively removes these low-concentration harmful gases, providing acceptable indoor air quality levels for scenarios such as product manufacturing processes, museums, hospitals, commercial office buildings, and cleanrooms.

The V-BANK Compact Filter is an extended-surface chemical filter that uses high-quality granular activated carbon (GAC), specialized chemical filtration media, or ion-exchange resin as high-efficiency filtration media, efficiently removing VOCs, odors, acidic gases, and alkaline gases in various commercial and industrial scenarios.To meet the stringent operating condition requirements of current complex air filtration systems, the V-BANK Chemical Filter is available in three standard sizes and two media loading levels: standard capacity and high capacity.

TheOdor & Particulate Filter（OPF）combines gaseous contaminant and odor adsorption with particulate filtration performance, achieving low airflow resistance and high gaseous odor capture efficiency.The filtration media uses granular activated carbon and potassium permanganate-impregnated activated alumina, uniformly adhered to high-efficiency polyester media, with an optional loading capacity of 250–800 g/m².The high-CTC carbon particles and activated alumina are mixed at a 50:50 ratio, with 8% potassium permanganate added, providing a specific surface area of nearly 500,000 m² per pound of mixture. The upstream layer achieves 70% filtration efficiency for 3–10 μm dust particles, while the downstream deodorization layer is impregnated with specialized chemical filtration media, effectively absorbing VOCs and malodorous odors.

The PM12 Packing Module adopts a disposable plastic shell or a reusable stainless steel shell, adopts a V-shaped structure design, has a molecular media bed thickness of 75mm, and has a design wind speed of 1.25 m/s. The filter is suitable for various application environments, is convenient for daily maintenance and replacement, can be pre-installed with filter materials according to requirements, or can be added or replaced with filter materials through a sealing cover, and can be filled with filter materials with various functions according to different user requirements. PM12 chemical filter is suitable for circulating filtration equipment of medium concentration pollutants, which can efficiently filter and purify gaseous pollutants.

The PM18 Packing Module features a disposable plastic housing or reusable stainless steel housing, with a V-shaped structure design, a molecular media bed thickness of 25 mm, and a design face velocity of 2.5 m/s. It is primarily applied in HVAC system equipment and devices.This Packing Module is equipped with a reserved molecular media sampling port, allowing molecular media samples to be taken and sent to the EcoKeeper laboratory for life analysis, ensuring that the molecular media fully exerts its filtration efficiency throughout its life cycle — avoiding increased maintenance costs from premature molecular media replacement while preventing harmful gas exposure from delayed molecular media replacement.

The Canister Chemical Filter (CCF) housing can be made of galvanized steel, stainless steel, or injection-molded plastic, and can be filled with various models of molecular media inside.The mounting plate is also made of galvanized steel or stainless steel, and can be customized to different specifications and sizes according to system operating conditions.This filter is suitable for HVAC systems and industrial fresh air, return air, and exhaust air systems, efficiently handling high-concentration gaseous molecular contaminants.Additionally, a customized solution with a filter membrane lining inside the canister can be provided, effectively suppressing dust and particulate matter from escaping.

The GridFilter (GF) Chemical Filter is a panel-type chemical filter featuring low pressure drop, large contact area, and high adsorption capacity. The honeycomb structure balances filtration efficiency and stability.
This filter is widely applied in medium-to-low concentration, high-air-volume scenarios, efficiently handling acidic, alkaline, and VOC gases. It seamlessly integrates with existing purification systems, offering strong adaptability.
The filter is available in two standard thicknesses, 46 mm and 95 mm, flexibly matching various operating condition requirements.

The APS-MINI features a cylindrical filter element structure, ensuring rapid return of contaminated air.The filtration layers, from outside to inside, are primary filter cotton, molecular media, and HEPA composite antibacterial & antiviral high-efficiency filter media, simultaneously removing dust particles, formaldehyde, benzene compounds, alkanes, VOCs, nitrogen dioxide (NO₂), nitrogen oxides (NOₓ), and malodorous odors, while killing airborne bacteria and viruses.Integrated canister filters in common market specifications and sizes can be customized.

The DAF Double-Flange Activated Carbon Filter is made of stainless steel perforated plates, filled with high-CTC premium activated carbon or molecular media. The double-flange design facilitates connection to ductwork.
This filter is widely applied in grow tents, grow rooms, basements, and garages, for removing low-concentration odors.
