We have had this Blueair silent air purifier for a couple years now and love it! My wife and I both have allergies and we run it in our bedroom every night. It is so quiet in fact that sometimes we forget to switch it off in the morning!
We live in a major city, which is very polluted.
It helps very much with dust and allergies. In fact, if I am having a really bad allergy attack (spring or summer after mowing the grass for example), I can go in my room, turn on the Blueair on high, and in a couple minutes my head and ears clear, my chest relaxes and the old “allergy headache” goes away.
This thing is better and faster than taking medicine!
Blueair customer service has been very responsive as well! When we order filters they always arrive even faster than promised.
Keep the filters changed, wipe off the outside from time to time, and you will enjoy clean air and fewer allergy headaches too!

I should start with the fact that everyone in our household has allergies, even the dog I think, but that had not been confirmed. Currently we have the Blueair units in all the bedrooms and family room. The best thing about Blueair units is they work! We really feel a difference. Before getting Blueair my wife was not able to sleep thru the night. She would get congested and her throat would get dry so she kept waking up to drink water. Whatever was giving her trouble is now gone from the air and she is finally able to get a good nights sleep.
Outside the fact that this unit cleans the air, I do also like that it is steel construction ( I did a lot of research and that is hard to find), its quiet!!!, and its energy efficient. This model also comes with interesting electronics. It has a handy little sensor on the side of the machine that actually measures particles and odors. I like that a lot because I can set it on Auto mode and it does all the speed changing by it self. Definitely takes the guess work out of what speed to run it on. As for warranty, the warranty card says mail in for free 5 year warranty.

We have this Blueair silent product in our bedroom and it is great! If I stay somewhere else without the Blueair I notice allergies.
Blueair quietly cleans the air in our room, and cuts back on the dust in our old home! If we don’t run it we notice dust.
On the highest setting it makes a slight but pleasant fan sound, but you are only to run it on high for a little while for example before going to bed. Then, turn it down a notch or two, and you will have uncongested sleep, and less allergy symptoms in the morning!!
It is worth every penny for the relief!!!

I have this air purifier for a few weeks now and in general I am very satisfied. I like the rugged, all metal case construction, and the very powerful fan that can really move the air around when you want it to (as opposed to some other purifiers which produce rather feeble air flow). Operation is simple and straightforward.
Here are some caveats though: The first unit I purchased had some slight rattle coming from the fan in silent mode. I returned that and it was fixed with a replacement unit. Also, the circuit boards in both the first and second unit I got emitted some quite noticeable “new computer smell” for the first couple days of operation. After about a week of use this was gone though. If you are sensitive to this kind of electronics smell you might want to run the unit for a few days in a different room before moving it to your bedroom. The quiet mode is very quiet but still ever so slightly audible (my wife is still bothered by it at night when the unit is close to her side of the bed), I wish the unit had an even slower, quieter mode.
Customer service was very helpful and went to great lengths to resolve questions and issues I had.

This machine is not silent, but it is reasonably quiet on the lowest speed. It does have a small blue light that cannot be turned off. I’ve been hanging a sock over the light to block it at night but will probably stick a piece of duct tape over it soon. The air does not seem as fresh smelling as the prior air cleaner I had, an Austin model.
