Great Classic 605!
The air quality improved a lot in my house, and plus it looks nice and fashion! Looks clean, neat design, and also easy to operate, I connected it with WIFI and I am able to control from my iphone App. It does a very great job and I bought another one! Highly recommended product! Must have!

Changed my life!
We were having horrible allergy issues and my asthma was out of control. We got 2 of the classic 605 units for downstairs and now we can actually breathe! No more issues! You can tell a difference within an hour! Thank you for an amazing product!

I like it!
My allergies were really nasty this spring and I could not seem to get rid of my runny nose and sneezes. I did some research and found that the Blue Air products were consistently rated highly. After some study of the models I decided that the Classic 605 was right for me and I bought it. After it had run for a day I noticed that my sneezing had stopped and my sniffles were minimal. I would say that this is an excellent product. It does what it claims to do and it's very reasonably priced for what it does.

may have kept my housemate from getting covid
I had covid recently--lower respiratory symptoms, lots of coughing--and my housemate somehow never got it. We also seem to have less dust collecting on surfaces in our home.

Simple and effective
This is the second classic 605 that I’ve purchased. I was impressed so much with the first that I bought another one for a different floor in my house. It’s built solid and moves a lot of air without a ton of noise. I like the medium setting since that cleans a lot of air without getting too loud. It doesn’t have any sensors but I like how simply it is made with a quality motor to last a long time.

Excellent Product
I purchased the 605 Classic because I saw a video on YouTube comparing BlueAir with 5 well known products. So far it’s been great, less dust than before. I have a very dusty cockatoo

Quiet, and excellent filtration
I've had my unit for several months now and only wished I bought one sooner. The Classic 605 is built extremely well, and is very quiet. The air is noticeably cleaner and my sinus issues have all but disappeared. The fact that the unit is on wheels makes it easy to move to different rooms. I did my homework ahead of my purchase and wanted a unit that had high quality filtering and was built in a way that it will last. Equally important the unit had to be quiet so I can have it on low during the day when I work. The Classic 605 does all these things exceptionally well.

Super Quiet!
We have two large Classic 605 air filters and one small classic. Love all of them! One we have had for 5+ years and have never had any issues with it. The 605 is extremely quiet on the lowest setting. On high, it is loud but it also cleans the air quickly and effectively. We wouldn’t be without our Bluair filters given levels of air pollution and wildfire smoke in the summers.

Doomed are allergens
We've have 2 and so fair it's made a vast improvement in home air quality. We have a cat and hamster. We all have terrible spring allergies but this year it's hardly noticeable. No more dust particles floating in the air. Takes care of cooking odors and other unpleasant smells. Very pleased and highly recommend this unit. Much better than other units owned in past. Had a few Holmes units but Blue air really does the job you expect and more. It really cleans the air, really makes a huge difference in dust. My house is cleaner, I'm not constantly dusting. My cats not even having her typical allergy face scratching issues anymore. Everyone is happy. Our son is sleeping better.

It's a workhorse!
We have one smoker in the house and this unit is on 24/7. It helps, but I think the amount of smoke is overwhelming.
