A Better Filter for a Cleaner Lab

Pathology Lab Filters

What Makes PSI Honeycomb Carbon Filters Stand Out

Air quality in the lab is critical. It affects everything from staff safety to the accuracy of your work. That is why choosing the right filter matters. At Pathology Service, Inc. (PSI), we offer Honeycomb Carbon Filters built to deliver strong performance, clean handling, and dependable value.

More Surface Area Means Better Filtration

PSI filters use a honeycomb carbon structure instead of loose pellets. This is not just a design choice; it plays a direct role in how well the filter works. The honeycomb format increases the amount of carbon exposed to airflow, providing more opportunities to capture volatile organic compounds, fumes, and odors.

Over time, the pellets inside these pellet-style filters can move or shift, potentially reducing their effectiveness. When the carbon pellets shift, open spaces develop, allowing some air to pass through without being filtered. PSI’s honeycomb carbon filters prevent this problem. The carbon remains fixed in place, enabling air to flow evenly through the filter. This stable design helps ensure reliable filtration and more efficient use of the carbon material, which can extend the filter’s lifespan and help maintain cleaner air in your lab.

Cleaner to Handle, Safer to Use

Handling pellet filters can be frustrating. They often spill fine carbon dust when opened or replaced, creating a mess and introducing unnecessary contamination risk. Dust can settle on equipment, interfere with lab work, and necessitate time-consuming cleanup.

PSI filters address that issue. Our honeycomb design keeps the carbon securely in place, preventing dust, spills, or additional cleaning. This makes installation and replacement quick, clean, and safe for technicians and the lab. It’s a small enhancement that streamlines workflow and improves the overall experience.

Built with Quality, Made in the USA

All PSI Honeycomb Carbon Filters are manufactured in the United States, including the activated carbon used in their construction. This helps ensure quality, consistency, and a reliable supply for labs that cannot afford to deal with shipping delays or unpredictable inventory. Our filters are built to meet the demands of high-performance labs and support professionals who expect results they can trust.

With a longer lifespan, easier handling, and strong filtration performance, PSI filters are a smart upgrade for any lab.

OEM-Equivalent Fit + PSI Value

Every PSI filter is engineered to match OEM specifications, making them a seamless drop-in replacement for your lab’s existing equipment. What sets us apart is the value our filters offer, providing the same level of performance and compatibility as OEM products at a more accessible price point. You don’t sacrifice performance to save money with PSI; you get both.
