Quiet long-range air purifier with smart function

• Very quiet, so also suitable for the bedroom
• Wide reach
• Smart function that switches on the correct mode itself
• Pretty big in size

I find the air purifier pleasant to use. He is very quiet. I don't really hear it during the day and it doesn't bother me when I sleep either. I find the smart function very useful. With this, the air purifier automatically adjusts the mode to the air quality, so that I don't have to think about this myself. The air purifier does take up quite a bit of space.

Info and control app
The air purifier can also be operated via the AEG app. Installing was quick and easy. In the app you turn the air purifier on and off. You will also find information about air quality. This information is only available for a few hours. I regret this. I would be interested in a weekly or monthly overview.

Wide reach
The air purifier has a large range of the space it keeps clean. I like this, because I only need one cleaner per floor.

Also cleans bad odors
Thanks to the carbon filter, the device also purifies bad odors. I notice this especially when cooking. My kitchen and living room are in one room. When I cook with a lot of herbs, I can also smell this in the living room. The food odors are gone faster than normal with the air purifier on. In the app I see the air quality deteriorating while cooking. I am positively surprised at how quickly the purifier cleans the air again afterwards.

sleek design
Despite the fact that the air purifier takes up quite a bit of space, the design is sleek. The handles are nice, because that way the air purifier is easy to move. Handy, for example when vacuuming.

Surprisingly good

• Nice stylish design
• silent
• Effective against allergies
• Format

We were able to test this AEG air purifier for 3 weeks, and the result was surprisingly good.

My wife has asthma and various allergies.
This was quite an experience for her, because all her complaints were almost completely gone.
And I myself noticed a big difference in the house, bad odors disappear almost immediately.

The size is striking, because it is quite bulky with a height of 73 cm.
But luckily the design is modern, and it wouldn't look out of place in the house.

More striking was the noise that the air purifier produces, namely almost nothing.
The device is almost completely silent in use, which also makes it suitable for a bedroom.

Only when strange smells come into the house, or during cooking, you will hear it working.
Then it will work a little harder, and you will hear that of course.
But this is also not disturbing, because usually after a minute or 3 it goes back to silent.

On top of the air purifier is the control panel where you can choose from 2 positions.
Smart or Manual, but we have it on smart 24/7.
You don't have to worry about it, it automatically adjusts the level that is needed at that moment.

The color ring on top indicates the quality, and for an extensive report with all the details, you can connect the AEG with the app.
This is quite simple, and once connected you can use the app immediately.

The app provides more insight into the air quality in the house.
This information is very extensive, but explained in detail with the meanings of, for example, a TVOS, or PM10.
But you can also read humidity and room temperature via the app.
The operation can also be done remotely via the app, so the control panel is not really necessary.

We are really surprised by the effect of this air purifier, and only now realize how nice it is to have it in the house.
What we still find unclear is the lifespan of the filter in the AEG.
It has a limited lifespan, indicated by percentages in the app.

After 3 weeks the filter is 95% with us
Once it is used up, it can no longer be used and must be replaced.
The downside is that they are very pricey.

I highly recommend this product for people with allergies, or who want a literal refreshment in the house.
You will notice the difference after a few days.

Nice, quiet, but doesn't help with my pet allergy.

• nice device
• very quiet
• App with statistics and schedule
• I don't notice a difference in my pet allergy

It is a very nice device. It is also very quiet, only in the higher positions is it disturbing. With the help of the app you can set a schedule (eg max at night, smart during the day). The app also shows some air quality statistics.
Setting up the app was easy, but occasionally the app wouldn't connect. That always resolved itself after a few minutes.
It is a pity that you cannot set a schedule for the ionizer. It would be useful to only turn it on at night.

Unfortunately, I don't notice any difference in the symptoms of my pet allergy, which I bought for. I know that another filter can be bought (AEG Breathe 360) for allergies, but the standard filter should also do something according to AEG, which is not the case with me. I will therefore not take the risk of buying such a different filter and returning the product. Regrettably!
