Notus – Alumina Beads
type: Product
description: Nevermore-Approved Notus™ Potassium Permanganate Media Alumina beads infused with 8% potassium permanganate (KMnO₄). Uses the same active oxidizer found in Nevermore Scorch-style media, but on an activated alumina substrate. Nevermore-approved by Ondsk4, creator of the Nevermore project. Made in Canada. Features Optimal Quantity: Each vacuum-sealed 2.15 L (~1.6 kg) bag completely fills one Nevermore StealthMax V1. Customizable Use: Can be mixed with activated carbon to extend service life while maintaining moderate chemical filtration. Long Shelf Life: Shipped in a resealable vacuum-sealed bag, allowing partial use while helping preserve freshness. Typical Properties H₂S Capacity (minimum) 0.10 g H₂S/cc Moisture 22 wt% Compaction (minimum) 2.7 kg (6 lb.) Particle Diameter 3.2 mm (1/8 in.) Apparent Density 0.88 g/cc (55 lb./ft³) Pressure Drop @ 50 fpm (0.25 m/s) 1.0 in. of water/ft. of bed Performance in Heated Printer Chambers Notus is better suited than carbon-only media for hotter printer chambers because its KMnO₄ chemistry does not rely solely on physical adsorption. Activated carbon loses much of its adsorption capacity as temperature increases, while potassium permanganate continues to chemically oxidize many contaminants. Actual performance still depends on airflow, media quantity, humidity, chamber conditions, contaminant concentration, and print duration. Why Activated Alumina Is a Great Match for 3D Printing Moisture Management: Activated alumina is hygroscopic. In a recirculating printer chamber, the enclosed air repeatedly passes through the media, giving the alumina additional opportunities to adsorb moisture around the filter bed. This may help support the KMnO₄ chemistry, but it is not a replacement for properly drying filament before printing. Improved Chemical Contact: The porous alumina substrate helps bring gas molecules into close contact with the KMnO₄ (the purple stuff), allowing adsorption and chemical oxidation to work together for more effec…
