Question: "The AeraSmart Sensor monitors the air quality and automatically adjusts the fan speed..." Can you turn this off so it stays on one speed?
Document: There are indicators to let you know when it is time to change each type of filter. If you are careful you can rinse the filters clean and reuse several times. This method is not as efficient as replacing with new filters but it can extend the filter life somewhat and save some cash.The AeraMax 200 has a three-speed fan. The "AeraSmart" sensor automatically adjusts the fan speed based on the air quality.
The best thing about this filter is the auto air quality sensor. Motor automatically kicks into higher speed once it detects a degradation in air quality and then reverts back to low speed once clean air quality is restored. In the long term it saves me electricity.
A little remodeling lot a dust + it's the high pollen season here in SW Fla.  A Gold Box Prime buy at a major discount.Extremely quite.unit don't even know its there. Visible sensor and auto fan speed adjust. Appears to work as advertised. Wife has noted a difference in air quality and dust reduction. Utilized in open floor plan Great Room/kitchen. Well Satisfied. Note replacement HEPA/Charcoal Filter non-Prime $45+, says it will last a year, we'll see. Recommended
It's great that we can adjust the fan speed if we know that we are adding pollutants to the air. If I know I will be spraying sunscreen or hairspray I usually go ahead and move the fan speed up to a higher setting to get a head start on it&#8230;but if I forget, the machine senses the fumes very quickly and adjusts accordingly.
The machine automatically sets itself, but you can set the fan speed manually if you desire. When running, it is very, very quiet.Filters must be replaced every three months for the carbon filter, and every year for the HEPA filter. At current prices, all five replacement filters will cost about $60 total annually, a real bargain for resolution of allergy problems.The only thing I would change about this air purifier is the overly bright indicators on the front panel.
I'm waiting to check the filter to see what is floating around my apartment. I've had it only a few weeks. I'm going to check it after six months. It's recommended to change the filter after a year. It runs so quiet, you hardly know it's on. I know it's doing it's job because when I glance at the panel, I can see the fan speed changes to accommodate the change in air quality.
The smart sensor on the product works very well, and increases/decreases the speed of the fan based on the need for purification. I have not set the device to manual mode, since the auto mode works so well.The device is very light weight and it would have been nice if it came in a darker color so it wouldn't stand out so much. Still, it sits in a corner of the room I don't face, so it is not a real problem for me.
Can't tell it's running when on low and high is a great high speed fan. I'm thinking about buying one for another room. Instructions are vague so you have to go online to learn more but other than that I love it.
It's quiet, automatically detects the right speed and does a good job filtering the air. I'm living with roommates with a cat, and have no major problems. Definitely worth it.
We have a small bedroom and this unit barely needs to go into high speed mode to keep the air in the room clean. We have both noticed a difference in our breathing - not stuffed up at all in the morning. We can tell this works because the few nights we have forgot to turn it on - I know it first thing in the morning when I try to breath.
Answer: Hello Sir,If I understand your question correctly, your asking if there is a manual mode speed adjustment in which you can control each of the fans speeds without interference from the automatic mode - If so the answer is YES.  This unit provides excellent control functionality allowing the user to manipulate the speed of the fan in any configuration.  The only exception to this is the 'Aera+ Mode' which can only be leveraged in automatic mode.I hope this helps answer your question.  I myself am very pleased with this purchase given the deal I found - It was a 'deal of the day' that also, (if one paid attention), had a coupon to clip for additional savings.  By the time I reached checkout, I owed only $109. After using it for sometime now, I would have easily paid what they are asking for today. Anyways, let me know if need any additional information.Regards,-A.Farrow
