Fellowes AeraMax 190 Air Purifier (Black)

What room size does the AeraMax 190 effectively cover?

The unit is designed for medium-sized rooms between 200-400 square feet. This makes it suitable for bedrooms, home offices, living rooms and similar spaces. The coverage area is based on optimal air changes per hour to maintain clean air quality throughout the space.

How does the AeraSmart sensor technology work?

The built-in sensor continuously monitors airborne particles and automatically adjusts fan speed accordingly. Blue light indicates good air quality, amber shows moderate contamination and red signals poor air quality requiring maximum purification. This automatic adjustment maintains clean air whilst minimising energy consumption and noise levels.

What types of particles does the True HEPA filter remove?

The True HEPA filter captures 99.97% of particles as small as 0.3 microns, including pollen, ragweed, dust mites, pet dander, mould spores, bacteria, viruses and cigarette smoke. The AeraSafe antimicrobial treatment prevents captured bacteria and mould from growing on the filter surface, maintaining hygiene and preventing odours.

How often do the filters need replacing?

Filter replacement frequency depends on usage and air quality conditions. The built-in indicators monitor filter life and alert when replacement is needed. Typically, the carbon filter requires replacement every 3 months, whilst the True HEPA filter lasts 12 months under normal conditions. Heavy use or poor air quality may require more frequent changes.

Is the unit suitable for people with asthma and allergies?

Yes, the AeraMax 190 is certified asthma and allergy friendly by the Asthma and Allergy Foundation of America. This certification requires rigorous testing to prove effective allergen removal and minimal particle re-emission. The unit specifically targets common triggers including pollen, dust mites, pet allergens and mould spores.

How loud is the air purifier during operation?

Noise levels vary by fan speed, with the lowest setting being virtually silent for bedroom use. Maximum noise output is 60 decibels, comparable to normal conversation levels. The AeraSmart sensor typically maintains lower speeds during good air quality periods, keeping noise minimal whilst providing continuous purification.

What is the high performance mode designed for?

High performance mode maximises filtration during allergy, cold and flu seasons when airborne contaminants peak. This mode increases fan speed and filtration efficiency to combat seasonal allergens, viruses and bacteria. Independent testing shows the unit is extremely effective at capturing influenza virus from indoor air during these critical periods.

Does the carbon filter help with odours and gases?

Yes, the integrated carbon filter specifically targets odours, cooking smells, pet odours and volatile organic compounds (VOCs). Carbon filtration works through adsorption, trapping odour molecules within the filter material. This complements the HEPA filtration by addressing gaseous contaminants that particle filters cannot capture, providing comprehensive air cleaning.
