Heat and moisture exchange (HME) filters are medical devices used in conjunction with mechanical ventilation to ensure the air inhaled by patients is adequately humidified and filtered. The medium is responsible for absorbing and releasing moisture consistently and releasing medication uniformly into the airways.
Our advanced heat and moisture exchange (HME) filter media made from 100% cellulose fibers are precisely engineered for seamless integration into respiratory filter media for ICU and anesthesia applications. Designed for use in mechanical ventilators, anesthesia breathing circuits, and other critical care systems, this medical filter media ensures optimal performance in demanding clinical environments.
With a high long-fiber share and a basis weight of just 90 grams per square meter, our cellulose HME filter media is very light-weight. It delivers best-in-class efficiency without compromising patient safety or filter lifespan.
Thanks to its superior moisture retention capabilities, our media maintains a stable balance between wet and dry pressure drop, enhancing humidity capacity and supporting consistent respiratory function. Its structure makes it an ideal hygroscopic filter for use in hygroscopic condenser humidifiers (HCH) and other HME applications.
The media’s adaptability allows for customized processing - such as slitting, pleating, and corrugating - making it suitable for a wide range of breathing circuit filter designs. As an ISO-compliant filter media, it meets stringent quality and safety standards required for modern respiratory care.
Our HME media stands out with superior moisture exchange. The secret is based on the properties of our cellulose fibers.
The careful processing of the fibers equipes the filter media with superior moisture exchange capabilities. This preserves the natural structure of the fibers, significantly enhancing their ability to absorb and exchange moisture efficiently.
In this way, an uniform humidification of the respiratory tract and a consistent dosing of medication are achieved.
Synthetic media encounters significant limitations with medication dosing. The breathing resistance rises to an unsuitable level after just a single medication dose, necessitating an immediate filter change.
With our cellulose media, several doses of medication can be applied without compromising efficiency and the breathing resistance remains constant.
When it comes to filtration efficiency and durability, not all filter media are created equal. Unlike traditional polyester filter media, which require replacement after each medication dosing, our solution delivers a lifespan that is twice as long.
Our cellulose-based material is engineered to endure mulitpledoses of medication without compromising its efficiency or structural properties. This ensures that our filter media can guarantee a significantly longer lifespan than synthetic media.
Compared to synthetic materials like polyester or foam-based media, cellulose HME media offers several key advantages:
- Multi-dose capability: Unlike synthetic media, which often require replacement after a single medication dose, cellulose media can handle multiple doses without compromising performance.
- Extended lifespan: Cellulose media can last up to twice as long as synthetic alternatives, reducing the frequency of filter changes and associated costs.
- Stable breathing resistance: Even after repeated use, cellulose media maintains consistent airflow resistance, ensuring patient safety and comfort.
The primary role of HME media is to manage heat and moisture exchange. To provide protection against bacteria and viruses, HME media is typically combined with a dedicated bacterial/viral filter layer - forming what is known as an HMEF (Heat and Moisture Exchange Filter). In such configurations, the cellulose HME media ensures optimal humidification, while the additional filter layer delivers high-efficiency microbial filtration.
Yes. GESSNER’s cellulose HME media is engineered for seamless integration with widely used respiratory devices, including hygroscopic condenser humidifiers (HCH), mechanical ventilators, and anesthesia circuits. Its flexible design allows for slitting, pleating, and corrugation to meet specific device requirements.
Absolutely. GESSNER’s HME filter media is made from 100% natural cellulose fibers sourced from sustainably managed forests. This makes it an eco-conscious alternative to synthetic materials, helping reduce the environmental footprint without compromising performance.
