Puritan Bennett Respiratory Products

Puritan Bennett is a long-established name in respiratory and ventilation care, trusted by hospitals, respiratory therapists, and home care providers for the reliability its equipment demands. This collection brings together Puritan Bennett accessories and consumables that keep ventilator and breathing circuits performing safely and hygienically.

A central concern for anyone managing a ventilator circuit is protecting both the patient and the machine from contamination. The Puritan Bennett Bacterial / Viral Filter (4-074601-00) addresses exactly that. Positioned in the breathing circuit, it captures airborne bacteria and viral particles, helping prevent cross-contamination between patients and shielding internal ventilator components from moisture and microbial buildup. For facilities that rotate equipment between patients, single-use filters like this one are a straightforward, essential part of infection-control protocol — and buyers typically stock them in quantity to match circuit change schedules.

When ordering, confirm the filter matches your circuit connections and expected flow resistance, and follow your device manufacturer's guidance on replacement frequency. High-humidity and heated-circuit applications may call for more frequent changes, so many respiratory departments keep a steady reserve on hand rather than ordering reactively.

If you're building out a broader supply list, it's worth noting the distinction between brands with similar names: Puritan Bennett focuses on respiratory and ventilation equipment, while our Puritan and Puritan Medical Products Company collections cover specimen collection swabs, applicators, and related diagnostic supplies. Checking the right collection saves reordering time and keeps your inventory accurate.
