Blueair HEPASilent Air Purification Unit

I have tried many types of purifiers over the years. My allergies would always lay me out and severely impact my quality of life. After becoming disillusioned by the Honeywell HEPAs and the Orek (eegads never buy the Orek!!!!!) I started a very detailed research project. Consistently, the BlueAir purifiers were at the top of every review and recommendation list. The only things beating them out were either attached to a house (I live in an apartment) or over $800. While the BlueAir itself is not cheap, I decided that my health was not worth saving the few hundred dollars another Honeywell would save me. It was the best $500 I ever spent. It runs quiet, it moves huge volumes of air and the filters are obviously doing their job. My allergies have subsided to a point where I no longer take meds! The unit has 4 speed settings, the lowest being called "HEPASilent" which is barely audible, and the highest being much too loud to use during sleep. I find the 3rd setting to b... Read more

The unit that runs these filters is top notch. Just be sure and shop around for a great price and bundle it up on Amazon with all your purchases for that great Free Shipping - which all the other web store fronts charge and can make filter buying very profitable for them and ridiculous for you!

I bought the 402 with the Smokestop filter as I smoke about 3 cigars a week in my apt in the wintertime. This model is good enough for my purposes, but if you smoke more than that I'd suggest the 501 instead. As others have noted, the 402 is silent on settings 1 and 2 and produces about the same amount of noise as a tower PC fan on setting 3. Setting 4 is noisy so I switch to that setting just before I leave for work if I've smoked the night before. When I return at the end of the day there us usually little or no smoke smell. I'd estimate the Smokestop filter to contain about 3 pounds of activated charcoal. Much more than the thin layer found in most filters. The unit itself is very well constructed and for an air filter it looks stylish. Access to the inside for the occasional vacuuming and filter change is extremely easy (large hinged side door).

I bought this unit last year. It does a good job of eliminating the dust. The owners manual says to replace the filters every six months. When I first read that, I thought that was just a tactic to make more money. After six months I checked them, and they needed to be replaced. With new filters, I turned it up to the next higher speed, and within three months they were dirty. The filters are not cheap (other brands aren't either), but that's the price I have to pay for cleaner air. This unit has four speeds. On one and two, it's almost silent. On speed three you can hear it, but it's not objectionable. I leave it on that one all the time. The highest setting is too loud. The unit uses electostatic technology, and at first the air seemed to have an unusual quality, like being at a high altitude. But after about a month I got used to it, and now I would never turn it off. The only objection I have to this and most of the low to moderate priced home air purifiers is they don'... Read more

I bought three of these for our townhouse - 1 for each level. We have 27 windows in this house (at least) and the dust is unbelievable! At first when I plugged in these purifiers I wasn't sure I noticed any difference so I did a test. I dusted in the master bedroom which gets the most dust (8 windows alone)and let this puppy go. Oh there was still dust after a two week period but then I dusted again and turned it off....the room was caked in dust so this purifier is definitely doing some heavy duty work. We've had these now for about 2 years and I think they're great! I'm glad we went with this model. After 6 months just look at your filters - it's amazing how much dirt this machine takes in.
