AeraMax Professional 4S Commercial HEPA Air Purifier Features
The AeraMax Professional 4S is a Fellowes commercial-grade HEPA air purifier engineered for shared spaces of 650 to 1,100 square feet — including classrooms, conference rooms, locker rooms, cafeterias, and clinical waiting areas. Its 4-stage True HEPA filtration system captures 99.97% of airborne particles at 0.3 microns, with the H13-grade HEPA element verified to capture 99.95% of particles as small as 0.1 microns under EN1822 testing. The unit was independently lab-tested to achieve 99.99% airborne reduction of Human Coronavirus 229E within one hour of operation.
For facility managers stocking commercial-grade air quality equipment, the 4S delivers something cheaper consumer purifiers cannot: EnviroSmart sensor technology that continuously monitors both air quality and room occupancy, automatically adjusting fan speed to balance cleaning power against energy cost and filter life. Combined with PlasmaTrue ionization and AeraSafe antimicrobial HEPA treatment, the 4S delivers consistent indoor air quality without manual intervention — and the included floor stand keeps the unit portable across spaces as needs change.
4-Stage Filtration System
| Stage | Function |
|---|---|
| Stage 1: Pre-filter | Captures large particles and debris, extending lifespan of downstream filters |
| Stage 2: Activated Carbon Filter | Reduces odors and volatile organic compounds (VOCs) |
| Stage 3: True HEPA Filter (H13) | Captures 99.97% of particles at 0.3 microns; treated with AeraSafe antimicrobial coating |
| Stage 4: PlasmaTrue Ionizer | Generates ionized field that helps remove airborne pollutants |

Commercial and Institutional Applications
To support indoor air quality programs in shared spaces, the AeraMax Professional 4S is widely deployed in K-12 classrooms, university lecture halls, conference and meeting rooms, locker rooms and gymnasiums, school cafeterias, medical waiting areas, dental practice front-of-house spaces, BSL-1 and BSL-2 laboratory anterooms, and aviation medical examiner office reception areas. The portable floor-stand design lets facilities managers reposition units seasonally — placing additional capacity in flu-season triage areas, then redistributing to summer programming spaces.

Frequently Asked Questions
What size room does the AeraMax Professional 4S cover?
The AeraMax Professional 4S is rated by Fellowes for shared spaces of 650 to 1,100 square feet, delivering 3 to 5 air changes per hour within that range. The unit will continue cleaning air in larger rooms but at a reduced air-change rate; for spaces above 1,100 square feet, Fellowes recommends deploying multiple units to maintain target ACH.
How often do the AeraMax 4S filters need to be replaced?
The True HEPA filter has an average service life of 12 months under typical commercial use. The activated carbon filter and pre-filter average 6 months. The unit ships with two of each filter type. Replacement HEPA filters are available as a 2-pack under Fellowes part number 9416601. The EnviroSmart sensor system displays filter status indicators when replacement is required.
Is the AeraMax 4S effective against airborne viruses?
Independent laboratory testing demonstrated the AeraMax Pro 4S achieves 99.99% airborne reduction of Human Coronavirus 229E within one hour of operation in a controlled test chamber. The True HEPA filtration system captures 99.97% of airborne particles at 0.3 microns — including bacteria, mold spores, and pollen — and the AeraSafe antimicrobial treatment inhibits microbial growth on the HEPA media itself.
What is the difference between the AeraMax 4 and 4S?
The AeraMax Pro AM 4 (Fellowes part 9416301) is a wall-mount only unit. The AeraMax Pro AM 4S (Fellowes part 9451201, listed here) ships with a floor stand for portable deployment — letting facilities managers reposition the unit between rooms or seasons without permanent installation. Both units share the same 4-stage filtration platform, EnviroSmart sensors, and 650-1,100 sq ft coverage rating.
