What Is a Deep Pleat HEPA Filter?
The Deep Pleat HEPA Filter is a high-efficiency particulate air Filter that deeply pleats fiberglass Filter material and mounts it within a rigid frame. Corrugated aluminum foil or paper dividers are placed between the pleats to maintain Pleat spacing and prevent collapse, while also uniformly guiding airflow through the Filter material.
Deep Pleat HEPA Filter Compared to the Mini-Pleat HEPA Filter, the Deep Pleat construction uses deeper pleated Filter media and separate dividing plates to support the Filter media assembly. Therefore, when selecting a model, you should confirm the air filter’s efficiency rating, rated airflow, initial resistance, installation dimensions, frame material, divider type, and gasket or liquid tank sealing method.
FiltEdge can manufacture filters based on your filter housing dimensions and actual operating conditions, helping you reduce issues such as size mismatches and inappropriate system resistance.
Divided by Partition and Frame Structure Deep Pleat HEPA Filter
Aluminum Separator Deep Pleat HEPA FilterCorrugated aluminum foil is installed between adjacent fiberglass filter materials. Filtedeg uses automated equipment to automatically fold and form the aluminum foil, and then assembles the formed aluminum foil with the fiberglass filter material at intervals. You can choose deep pleat HEPA filters.
Temperature, humidity, and the presence of corrosive gases need to be specified.
Galvanized Steel Frame with Partition HEPA FilterGalvanized steel frames are suitable for those requiring rigid housings and are relatively economical in price, making them suitable for most conventional filter tanks. You need to confirm the installation method, actual dimensions, and gasket location of the original filter box to ensure that the new filter can be installed smoothly and maintain a good sealing effect.
Stainless Steel Frame with Partition HEPA FilterIf the filter is used in crystallization areas, humid environments, or if the project explicitly requires the use of a stainless steel frame, we can determine the stainless steel material and surface treatment method based on the actual working conditions. If the frame material is changed, the dimensions, structure, and installation method need to be reconfirmed.
Temperature resistance is determined by the least resistant of filter media, separators, sealants, gaskets, and frames. Please provide continuous temperature, peak temperature, and duration of sustained high temperature; Only with this confirmed information can we provide you with the appropriate air filter.
For older equipment, non-standard filter boxes, and OEM units, you provide the actual measured dimensions of the old air filter. We will confirm the airflow direction, protective net, label fields, serial number, packaging method, and product structure for you, completely avoiding sample and equipment mismatches.
Deep Pleat HEPA Filter Features Box
Deep Pleat HEPA Filters adopt Deep pleated glass fiber filter material, molded separator and rigid frame structure, which has the characteristics of high filtration efficiency, large filter material area, stable airflow channel, high dust capacity and firm structure. You can choose the appropriate configuration based on the rated airflow, installation size, and filtration level to ensure the particle effect while reducing problems such as excessively rapid pressure differential rise, frame deformation, loose sealing, and replacement frequency.
Deep Pleat HEPA Filters can meet HEPA filtration requirements, with a filtration efficiency of no less than 99.97% for 0.3um particles. They can reduce the entry of fine dust, aerosols and other particles into clean areas and are usually used as end-air filtration.
After the glass fiber filter material is deeply folded, the filtration area can be effectively increased, and air is dispersed to more filter material surfaces when passing through, avoiding local accumulation of particles, effectively delaying the rise of resistance, and reducing premature clogging of the filter.
Deep pleated filter media provides more space for contaminants, is suitable for continuous operation systems with high particulate matter loads, can effectively reduce downtime, and directly lowers labor costs, spare parts, and waste air filter disposal costs.
Corrugated aluminum foil or other molded partitions are installed between adjacent filter material layers, which can ensure that air reaches the inside of the filter material, reduce filter material adhesion and local collapse, and make full use of the filter material.

According to the EN 1822 standard, the overall filtration efficiency of H13 is not less than 99.95%, and that of H14 is not less than 99.995%. Testing is based on the most permeable particle size (MPPS). If you are using the US HEPA standard, you need to confirm whether the filter has an efficiency of at least 99.97% for 0.3 μm particles.
FiltEdge Deep pleat HEPA filters typically use aluminum foil or paper separators to support Deep pleat filter media and are suitable for full-depth filter boxes and industrial AHUs. Mini pleat HEPA filters typically use hot melt adhesive to split filter paper, resulting in a more compact structure and are generally used in end filtration, FFU, and cleanroom equipment where space is limited. When choosing between the two, it is necessary to compare the installation depth, rated airflow, and allowable resistance.
Deep Pleat HEPA Filter The replacement cannot be judged based on the month; it should be determined in conjunction with the final resistance, system airflow, particle monitoring results, and your on-site maintenance requirements. FiltEdge typically recommends a final resistance of 450 Pa.
