High-efficiency Separatorless HEPA Filter made of superfine glass fiber media, designed to capture airborne particles ≥0.3μm. It serves as the final-stage filter in various filtration systems. The frame is anodized for enhanced strength and corrosion resistance, while the air inlet and outlet are protected with powder-coated grids to prevent damage to the filter media. Each filter is strictly tested, with filtration efficiency rated at H13 or H14 (EN1822). With low operational costs and long service life, this filter is ideal for cleanrooms, pharmaceuticals, electronics, food processing, and other environments requiring high air purity.

FAQ
1. What is a separatorless HEPA filter and how does it differ from a traditional one?
A separatorless HEPA filter uses hot-melt adhesive instead of metal separators to maintain pleat spacing. This design ensures uniform airflow, reduces air resistance, minimizes particle leakage, and lowers overall operating costs compared to conventional HEPA filters with aluminum separators.
2. What filtration efficiency levels are available?
Our separatorless HEPA filters are available in H13 and H14 grades, conforming to EN1822 standards.
H13: 99.97–99.99% @ 0.3μm
H14: 99.995–99.999% @ 0.3μm
Each filter is individually tested to guarantee performance consistency.
3. Where can these filters be used?
They are widely used in environments that require high air cleanliness, such as:
Electronics and semiconductor cleanrooms
Pharmaceutical manufacturing and laboratories
Food and cosmetics production lines
Hospitals and medical facilities
