Bedroom Machine White - Advanced 5 - Stage Filtration Air Purifiers For Home with Activated Carbon & Zeolite - Ideal as Air Purifiers for Bedroom, Model B402

I have severe allergies and have tried everything I plugged this in on high first thing in the morning and within 24 hours my house smelled cleaner and couldn't see a dust particle anywhere. I got my first restful night sleep and was able to breath better then I ever have before. As an added benefit my cat has allergies and she has been better well. We shall see how long the filters actually last but for know it is well worth the money. It is loud but that should be expected since it moves so much air through the filter it is necessary. We turn it on low while sleeping and it just sounds like a box fan. It also has heavy duty casters and we roll it into different areas of the house to purify the air throughout the entire house. It doesn't have many bells and whistles but I figure that is a good thing less moving parts to break. Thank you Austin air bedroom machine for the better nights sleep.

I bought this unit 2 years ago due to a FSA SNAFU where I accidentally fully funded it and had to spend the whole thing at the end of the year or lose my money. I keep it running in my bedroom all the time on the lowest setting. It's definitely less noisy than all the road/ambient noise we have from outside, so I don't even notice it's on. I had no idea if it was actually really cleaning the air or not- anecdotally, it did seem better in the room it was running in when we had to keep all the windows closed due to wildfire season. However, I always was curious how well it was doing in a measurable way. So, I recently got a AQI sensor. As an experiment, I seasoned some cast iron pans sending the AQI in my house up into the 400 range. I'm sitting in my bedroom now with the air purifier running on level 3 and after about 20 mins, it has lowered the AQI to 30. So now I feel confident in saying that this was a good buy and I don't feel bad about accidentally putting too much money into a use-it-or-lose-it FSA account!

Cord is about 5 feet long; manual says extension cord shouldn't be used. Approximate sound levels: low is almost unnoticeable and quieter than any of the other three different sized fans I use in summer on their low setting; medium is similar in volume to the fans on their medium settings, and during the day I don't find it distracting above typical room noise; high setting I would compare in volume and quality of sound to the fans of the air conditioning/heating units of most hotels I've stayed in, definitely tolerable for an hour or so during the day, but probably not when trying to sleep (although at least unlike hotel air conditioners, this fan's white noise stays constant instead of cycling on and off). That being said, some articles I've read have indicated the activated carbon's functionality is greatly increased by the longer contact with the air achieved when running the machine on low rather than high, so the sound on high may not be much of an issue anyway (although the product manual does recommend letting it run on high for the first hour of use). When viewed from the front (where on/off dial is), cord is on the back side, and air exits to your right. The exiting air is directed quite high up, and also forward (in your direction and towards the side, but not towards the back). This flow is convenient for the locations where I'm able to situate the air purifier. The size and weight provided in the product description were very accurate, but I was still surprised when it arrived. It's not quite as deep as a filing cabinet, but about the size of a nightstand. I'd been considering placing it on a small table, but the upward directed airflow makes that unnecessary, and the weight may actually be too much for the table, and I'd have had to try to uninstall the wheels that come already attached.

I bought the same bedroom machine 8 years ago and have been impressed with how well it is done and the quality, however thing one was completely covered in silica or charcoal or something of that nature. The sticker fell off when I was trying to clean up the mess it made my house. The fan motor runs nothing like the old unit. Level one the thing barely turns level 2 is comparable to level one on the older unit from 8 years ago but whistles and whines. Night and day difference. Their customer service is great however and amended my concerns

At 80years old I was just diagnosed with HCHO/formaldehyde poisoning. This has been life saving to me. I bought a monitor to help me get a handle on the HCHO. My apartment registered almost 900 on the monitor when I first tested the air quality. Within 48 hours the HCHO count was under 200, and now it is holding at less than 1 to 20. I call that a win. I set the machine on low or medium, and it makes a great white noise for great sleeping. Worth the expense. This should help me for the rest of my life. Also, was shipped in a very sturdy box, no damage. Came in 2 days. Easy to get out of the box too.😷.

I have bought this model because it said it was good for people with MCS. The off gasing from the unit made me sick. I am contacting the company during the week and will post another review on what they say. If you suffer with this condition you might want to think again before buying it. Other than being a little noisy on high it is a great machine and does move a lot of air. For someone not dealing with MCS it could be a good unit.. I followed up with the manufacturer and told them about the odor from the unit. Off gasing that I smelled. They were very helpful and told me the smell is coming from the filter system. They were willing to send me another type of filter but assured it would not help with MCS. They instructed me to send it back and get a full refund. I followed amazon return procedure. I will follow up with another review on my refund. I have to say the company was great in how they handled my call and treated me. I give the unit a 5 star as well as the company. Don't know why someone wrote to stay away from this company because of how they got treated. I personally experienced just the opposite. They were extremely cordial, accommodating etc. Back to the drawing board to find another unit good for MCS.

This is a sturdy unit and probably works fine for the average person. Unfortunately I have mcs and this unit offgasses something which makes me feel worse than I do without the air purifier. It is very frustrating to believe if you spend enough money an air purifier will help only to find out it makes you worse.
