Fellowes AeraMax SV Air Purifier (White/Black, 4-Speed)

How often do the filters need replacing and what do they cost?

The H13 HEPA filters are rated for 2-year lifespan under normal use conditions, significantly longer than typical air purifier filters that last 6-12 months. A complete filter set currently costs around half the price of the unit itself, but the extended lifespan makes it more economical over time. The washable pre-filters should be cleaned monthly to extend main filter life. The unit displays filter life remaining and alerts when replacement is needed.

What room sizes can this air purifier effectively handle?

The unit is rated for rooms up to 1500 square feet maximum coverage. For optimal performance, it provides 3 air changes per hour in rooms up to 915 square feet, or 5 air changes per hour in 549 square feet. Room height affects performance - the ratings assume standard 8-10 foot ceilings. Open floor plans or rooms with high ceilings may require positioning closer to the area needing purification.

How loud is the AeraMax SV during operation?

Speed 1 operates virtually silently and is barely audible. Speed 2 remains extremely quiet with minimal sound. Speeds 3 and 4 produce more airflow noise but maintain a pleasant whoosh sound without mechanical whines or rattling. Sleep mode operates on the lowest speed setting whilst turning off all display lighting. The sound quality is designed for 24-hour operation without sleep disruption.

Does the AeraSmart technology really work automatically?

Yes, the built-in PM2.5 sensors continuously monitor air quality and display real-time readings on the control panel. In auto mode, the fan speed adjusts automatically based on detected particle levels - increasing during cooking, cleaning or when outdoor pollution enters, then reducing when air quality improves. This provides optimal cleaning without manual adjustment whilst conserving energy during clean air periods.

What types of pollutants does this air purifier remove?

The H13 HEPA filter captures 99.95% of particles as small as 0.1 microns including pollen, dust mites, pet dander, bacteria, viruses and smoke particles. The activated carbon component reduces odours, volatile organic compounds (VOCs) and chemical vapours. However, it cannot eliminate all odours - particularly strong cooking smells or chemical odours may be reduced but not completely removed.

Is the unit difficult to move and set up?

Despite weighing 16.92kg, the unit includes built-in casters for easy rolling movement and integrated carrying handles for lifting. Setup requires no tools - simply remove packaging, install filters through the magnetic side panels and plug in. The magnetic panels make filter access simple without complicated latches or screws. Safety switches automatically turn off the unit when panels are opened.

Can I use the air purifier continuously without issues?

Yes, the AeraMax SV is designed for 24-hour continuous operation. The motor and components are built for constant use without overheating or premature wear. The ultra-quiet operation on lower speeds makes it suitable for bedroom use overnight. However, the unit does not automatically restart after power outages and always defaults to auto mode when turned on, rather than remembering previous settings.

What warranty coverage is provided with this air purifier?

Fellowes provides a comprehensive 3-year manufacturer warranty covering defects in materials and workmanship. This extended warranty period reflects the unit's commercial-grade construction and expected longevity. The warranty covers motor, electronics and housing but excludes consumable filters. Fellowes has over 100 years of experience in workspace products, providing confidence in long-term support and parts availability.
