Fellowes’ AeraMax 300 Large Room Purifier is a stylish HEPA purifier with cool touch controls and a modern look.
Although it is a bit more expensive, this air purifier is much more powerful than other models.
It covers large areas up to 600 square feet. It has a 3-stage filter process, which includes a negative-ion generator.
You will find four fan speeds, an automatic mode, and an indicator of air quality.
Our favorite feature is Aera+ mode, specifically designed for allergy season. This will come in handy if someone in your home has allergies.
These features are fantastic, but there are some missing features such as a sleep mode (lights won’t go off) or a timer.
Some complain that the purifier makes a loud whining sound even though it runs at the lowest speed.

1. 3-in-1 Air purifier
The AeraMax includes two primary filters and a negative-ion generator.
HEPA filters have an antimicrobial treatment that prevents bacteria and mold growth on the filter.
The negative ion generator improves air filtration and freshen the air. You can switch off the ionizer if you don’t like this feature of an air purifier.
2. Ideal for large rooms
The AeraMax300 is also useful in large rooms up to 600 square feet.
This is the right air purifier to fit your large bedroom or open-plan living space.
3. Four fan speeds plus auto mode
There are four speeds available, ranging from low to turbo.
Air purifiers work faster if the fan speed is higher. Turn on turbo or high speed to quickly remove smoke and dust from the air.
Attention! The air purifier can be quite loud at high speeds.
Even worse, it isn’t a white noise hum. Instead, it’s a whiny sound that doesn’t completely disappear even if you lower fan speed.
They should have found a quieter way to purify the air for half the price.
You can choose auto mode if you don’t wish to change the fan speed.
Based on indoor air quality, the purifier will automatically choose the most efficient fan setting. The integrated sensor determines how clean or dirty the air is.
4. Air Quality Indicator
The indoor air quality can affect the color of an LED light. For example, if the LED light is red, it means that your indoor air quality is very poor.
If the purifier isn’t in auto mode (in which case it will automatically increase fan speeds), you can manually increase the fan speed.
If it is amber, your air quality falls somewhere in the middle. If it is blue, your air quality is good.
5. Mode For Allergy Season
Turn on Aera+ mode during allergy season to improve performance.
To remove allergens, the air purifier will draw in more air.
The AeraMax 300 is quite expensive, but it does not lack some essential features.
One, there is no sleep mode to decrease fan noise or dims the lights.
Some customers block vents by placing a cloth on top of their air purifiers at night.
Even the most expensive air purifiers come with a button that turns off the lights.
There is no timer. This feature is also common on many lower-priced air purifiers.
Noise is another frustrating problem. Customers report a high pitch noise that gets louder as the fan’s speed increases but doesn’t disappear completely when the fan speed reduces.
It can be particularly bothersome at night when it is more prominent.
We don’t believe the AeraMax 300 is worth the price. It lacks some essential features, and the high-pitched sound is unacceptable at this price.
For less, you can buy a larger HEPA air purifier with a sleep mode and quieter operation.
It’s a great option if you have an allergy and need an air purifier with the extra power to eliminate allergens from your indoor air.
