Full review

Our hands-on assessment and where it fits.

The Fellowes AeraMax 100 is a compact HEPA air purifier designed for small to medium-sized rooms, making it well suited for bedrooms, home offices, or nurseries up to roughly 200 square feet. At its core, the unit relies on a true HEPA filter capable of capturing 99.97 percent of airborne particles as small as 0.3 microns, including dust, pollen, pet dander, and mold spores. This is paired with an AeraSafe antimicrobial treatment on the filter itself, which helps inhibit the growth of bacteria and mold within the filter media over time, extending its effective lifespan and maintaining cleaner output air throughout its use. Beyond particle filtration, the AeraMax 100 incorporates a carbon filter layer intended to reduce common household odors, such as those from cooking, pets, or smoke, along with certain airborne chemicals and VOCs. The device features a four-stage filtration process and includes PureView technology, which uses a smart sensor to continuously monitor air quality and automatically adjust fan speed to respond to real-time conditions. This automatic mode removes the guesswork from operation, allowing the purifier to ramp up when pollutants spike and quiet down when air quality improves, all while displaying status through a simple indicator light system on the front panel. Physically, the AeraMax 100 has a slim, tower-like footprint that fits easily into tight spaces without dominating a room's décor, and it operates with multiple fan speed settings so users can choose between quieter overnight operation and faster clearing during periods of higher particulate activity. Maintenance is straightforward, with a filter change indicator light alerting users when it's time to replace the HEPA and carbon filter cartridge, removing uncertainty around upkeep schedules. Overall, the AeraMax 100 combines true HEPA performance, odor-reducing carbon filtration, and antimicrobial filter protection into a single accessible unit, positioning it as a practical entry point for anyone seeking noticeably cleaner indoor air in smaller living spaces.
