The ENERGY STAR name and mark are registered trademarks owned by the U.S. EPA Review: Its quiet - This machine is quiet, and works good. Since I've had it I've seen no dust in the air and less dusting. There is dust but not as much. Also my nose isn't as runny. I love this air purifier. Review: Low level hum ruins and otherwise good air purifier - I had the previous model, the HPA 100, for my daughter's bedroom and it worked out really well. I went with Honeywell because it seemed to have good features without creating ozone which was important for me. I decided that I wanted to get one for our bedroom too. Lo and behold there was a new version available. The new version is a little slicker looking, though, the clear plastic portion looks a little cheesy / will probably be prone to scratches. It is also a bit more efficient. However, the older model actually may cost less money to run because it uses less electricity / is smaller. This is also a bit bulkier than the old version, though the trade-off is it does purify more air. The real sticking point, though, was the low-level hum that this unit and the bigger models emited. It seems that the actual fan noise might be a little bit lower, and maybe I am just not used to this particular frequency of noise, but I just couldn't get over it. I also tested the noise volume between the new model and old model with a DB app and it did confirm that the new model was about 5 dB louder. This is in no way a scientific comparison, but it confirmed my anecdotal feelings about it. I have lots of fans, and music products, and none of them emit a hum like this. I usually associate a hum like this with some sort of grounding issue. Ultimately, I was disappointed and I returned it.

Its quiet
This machine is quiet, and works good. Since I've had it I've seen no dust in the air and less dusting. There is dust but not as much. Also my nose isn't as runny. I love this air purifier.

Works as advertised
This air purifier fits great in my mom's bedroom, she sets to sleep mode, sleeps through the night and wakes rested. It's just as useful in the living room dining room. Removes odors and purifies air so no problem with her allergies.

Also A Nightlight
First, I want to start by saying I love this air purifier. It does a great job in keeping our bedroom air clean and has been a great help for my allergies. The replacement filters are a little expensive, but that is true with most quality air purifiers. I have two issues with this purifier that I don't love. First, the clear plastic piece on the back of the top lights up, which highlights how cloudy it gets. A few weeks after I got it it started looking cloudy and I tried to clean it, but haven't found anything that does a good job. Second is that there is no way to get all of the lights to turn off on it. On the control panel there is a light bulb button that will allow you to change the brightness of the controls and indicator, but when you turn them off the lightbulb button itself stays on. Because I have this in the bedroom I find that incredibly annoying and have to keep a cloth on top of it to block the light. I'm not sure that manufacturers know this, but not every single device in our homes should also be a nightlight!

Nice little air filter
Nice little air cleaner, we have cats and run it constantly to help keep dust and fur out of the air. It has been running for 3 months straight with no issues. We pull out the pre-filter and bang it off outside every month or so cause it does catch a lot of cat fur, but the inside filter is still chugging along. Its very quiet, i forget its there most days. Not sure if it helps with allergies or not, i dont sneeze any more or less than i always have, but i dont have any known allergies to dust or pollen. It has a small footprint so it fits easily in a corner or under a desk.
