Healthy Filters Customized 0.1um HEPA Separated High Efficiency Air Filter H13 Large Merv 18 U15

A deep pleated HEPA (High Efficiency Particulate Air) filter is similar to a standard HEPA filter but has deeper pleats, providing greater filtration surface area within a compact space.

1. Greater Filtration Surface Area: Deep pleated HEPA filters have pleats that are deeper compared to standard HEPA filters. This design increases the available filtration surface area, allowing for more efficient capture of particles.

2. High Filtration Efficiency: Like standard HEPA filters, deep pleated HEPA filters are highly efficient in capturing particles as small as 0.3 microns, with a minimum efficiency of 99.97%. The increased surface area of the deep pleats enhances filtration performance.

3. Compact Design: Despite having deeper pleats, deep pleated HEPA filters are designed to fit into standard filter housings or air handling units. This allows for easy retrofitting into existing systems without requiring significant modifications.

The deep pleated HEPA filter includes three types: paper clapboard high-efficiency filter, aluminum foil clapboard high-efficiency filter, and high-temperature resistant clapboard filter. It is extensively utilized in various industries such as electronics, semiconductors, precision machinery, pharmaceuticals, hospitals, and food, to achieve high cleanliness standards in both civil and industrial clean environments during the final filtration stage.

High-volume high-efficiency air filters with a shape similar to that of a computer chassis are made of metal or plastic housings sealed with a specific sealant (polyurethane adhesive), and the filter element is made of fiberglass filter paper. This kind of filter has a regular appearance and is easy to install, which reduces the installation time and labor of workers. The dust holding capacity is several times that of an ordinary high efficiency air filter without partition, and the designed maximum air volume is also several times that of an ordinary high efficiency filter without partition, which greatly reduces the running cost of the enterprise.
