Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Perfect for use while sleeping
During the night, you can set this air purifier to sleep mode. This sets the purifier to work only in the lowest speed setting. Additionally, the indication light is dimmed to a level that it reassembles a gentle night light.
Pro Brings fragrance to your room
A standout feature for this purifier is the aromatherapy pod. You can fill it up and, when the purifier is working, it will not only clean the air, but also mix aroma in the air, helping you sleep or concentrate.
Pro Multi-level filtering
Like most of the purifiers, this one has a HEPA filter for removing the smallest airborne particles and an activated carbon filtration system to remove odors and gases. It also has an ionizer that charges oxygen molecules, which helps to capture more dust particles in the next air pass-through.
Pro Adds vitamins to the air
Besides filtrating the air, the purifier also enriches it with Vitamin A. Aerus claims that this makes the skin softer and reduces stress.
Pro Highly portable
The purifier is very lightweight (12 pounds) compared to regular-sized and even some other compact purifiers. Moreover, this device has a slim 9" profile, making it very handy to carry around.
Pro Filters air very well
This purifier uses a four-stage filtration process to clean room air very efficiently. First, the air goes through a washable pre-filter that captures large particles like hair. After that, the carbon filter removes odors and gases. Finally, the HEPA filter captures the smallest particles, like dust, fur, animal dandruff and other allergens.
Pro Great performance while taking care of big rooms
It's meant for spaces up to 350 square feet, but does a quick and clean job for spaces twice as large.
Pro Has a timer
You can set the purifier to switch off after 1, 4 or 8 hours. This can come in handy if you want to run the purifier while you're not at home.
Pro Has eco and auto modes
The purifier can be set to an automatic or eco mode. Both modes are very similar and work with the particle sensor. The only difference is that while in eco mode, if the air pollution level is at its low for more than 30 minutes, the purifier disables the fan. While in auto mode, the fan will continue working on its lowest setting.
Pro Can indicate air quality
The intuitive Air Quality Indicator uses particle sensor technology to monitor the indoor air quality and displays the status using a LED. It will be blue when the air is clean, purple when moderately polluted, and red when the air is heavily polluted.
Pro Quite efficient
This model has a CADR of 246 for dust, 240 for pollen, and 233 for smoke. This is just below the average of 250 and means that the purifier will clean the air with ease if the situation isn’t extreme, like rooms where people are smoking heavily.
Pro Energy efficient
The unit uses a maximum of 77W of power, but only 7W on low setting with the ionizer off. That's less than a LED light bulb. There's also an ECO mode that turns off the fan and the ionizer if the air quality was good over the last 30 minutes.
Pro Fan speed can be regulated according to your needs
The machine has three different fan speeds: there's a low, medium, and high setting, with low being a quiet whisper mode that puts out a light breeze, and high being noticeably louder, but circulating the air almost like a full-sized purifier.
Pro 360º air circulation
Unlike most air purifiers, this unit pushes clean air up towards the ceiling where it flows further down the walls, then over the floors and back towards the device, creating a 360º air current pushing dirty air and particles into the unit.
Pro Air sensor is easy to clean
To get the most accurate readings, you need to clean the air quality sensor occasionally. It is located on the side of the unit, behind a little latch, and it's very simple to reach without taking apart the whole device.
Pro Intuitive controls
There are only five clearly labeled buttons used for controlling the purifier, all of them with LED indicator lights. This makes operating the device very easy.
Pro Costs little to maintain
Over 5 years, you should expect to spend around $600 on the purifier, including filters and electricity. Other models can be much more expensive overall.
Cons
Con Replacement filters are hard to find
The replacement filters aren’t as easy to find and buy as those from competitor units.
Con Can't be bought in California
Due to legal reasons, this product is currently unavailable in California.
Con Too sensitive air quality sensor
The air quality sensor is overly sensitive, so it shouldn't be left turned on in the bedroom during the night, since the unit can suddenly start to blow at full speed and become very noisy.
Con Can't be controlled remotely
This air purifier lacks a remote control.
Con Air quality indicator is too bright
The air indicator is very bright and can become very noticeable during the night, so much that it might even disturb your sleep.
Con Only handles particulate matter
It does not remove Volatile Organic Compounds (VOCs) nor fragrances which would matter a lot for certain people with allergies or who live in environments with people who smoke or pets.
Con Strange power proportions
The lowest and the second power levels are almost identical while the maximum level is deafening and strong. Because of this, the purifier can be running quietly in the automatic mode and then, suddenly become very loud, just to become quiet again after a while. This can be very disturbing, especially during the night.
Con Doesn't have a sleep mode
The purifier doesn’t feature a sleep mode that dims the lights and disables the highest setting of the fan.
