Perfect for our asthmatic household. *Updated
My toddler and I both have severe allergies and asthma. To the point that over the past month we have both been having major issues with the pollen and smog in the air, even with being home most of the time! I ordered this one after doing A LOT of research, and I decided this was the best for the money. With a true HEPA filter that you replace once a year (opposed to once a month) it would save money in the long run. I chose this one for the den in our house and over the coming weeks we will be getting smaller ones for the bed rooms.This review for right now is 24 hours in to having it on in the house, and later I will come back and add to it.Set up was easy straight out of the box, and I put it out of traffic areas in the house. I was worried with where I put it there would be trouble for good air circulation, but it is doing great! In fact with it on high I noticed a tag on the other side of the room (directly across) was moving on one of the toys yesterday as I was cleaning. Then I cooked fish last night (our den has an open doorway to the kitchen), and I couldnt even smell it cooking!! I decided to test it this morning, and sat on the couch painting my nails. Even using nail polish remover I couldnt smell it!!! (which astounds me b/c I hate doing my nails simple b/c of the toxic fumes!!) As far as noise, its not that bad. On high, with the tv and with kids running around it is a little white noise and thats it. I sleep with the bed room doors open, and having a tower computer on in the den annoyed me, however on medium I couldn’t even hear it in the den! It also moves a lot of air b/c even when the ac isnt blowing air, it feels like it is b/c of this tower! I am super excited at the thought of having better air quality in the house so we dont have as many issues, and I know it will take probably a good month for me to be able to judge that (and trust me I keep up with our flair ups b/c my son sees a specialist so I can tell you if it will make a difference or not). I also liked the UV light, since we have kids over to play all the time it makes perfect sense to have it to.Also anyone that has lung issues, make sure to avoid any purifier that has the ion part (where you turn it on for a fresh smell) it actually causes lung problems (if you have underlying problems). Oh and check out the reviews on walmart . com for this purifier, it has hundreds of reviews and most are five star (which is one of the reasons I went with this model even though not everyone loved it on here).Check back in August and I will add an update =)****************************UPDATE****************************** 12/2/2012Hi ALL! Sorry took me so long to come back and update =) Fortunately if you see below I did give a heads up three weeks in we still loved it. This unit is holding up well, and really does a good job! Since buying it (I guess going on six months ago now –WOW THAT WENT FAST!!) it helped with our asthma and allergies. Within the first month I stopped waking up with a stuffy nose, and it was taking particles out of the air so I wasn’t seeing as much dust. I still would love to have them in each room, but that is on the back burner. Make sure you have enough for the sq footage of your room. We have since moved to a larger place, that has more sq footage in the den, and also two open doorways leading to other rooms. As such, this unit is doing really well for how much air it has availability to; when I should honestly probably should have one more in here. It isn’t too loud, and I love the uv light. Within the first month of us having it we were exposed to someone (a visitor) that wound up having pneumonia. With the fact we have a higher risk of catching lung illnesses, I was really nervous. I think a big contributor to not catching it is because we had this unit running on high with the uv light. I highly recommend this unit, and I hope it helps! =)***********************************Update 6/26/13We just about hit the year mark! Still working great and going strong! Make sure you wipe down (inside and out) once a month (as the book says). Still going strong, and working well! =) Buy this one, and you wont regret it!***********************************Update 11/13/13Unit is still working great! We added a second one earlier this year, and pleased with both! =)***********************************Update 06/29/14Both units are still going strong with no issues. Still helping with our asthma and allergies.

This thing has saved meeee and my nostrilssss by far. The apt I live in is a bit old and I do have a dog who sheds a lot, but have no feaaaar. This product will make you forget about all of your dust and fur problems. Easy to use, if the filter needs to be change the color of the light will change, I keep on the highest fan speed at all times, and the longevity of it is great. I’ve had it for almost a year now and it has not gave out on me, I haven’t had to change the filter once, and it does a pretty amazing job of filtering the air. It’s a very decent size so it does not take up too much space in your room or living room and you can definitely feel the difference in the quality of air. I also smoke and when I tell y’all, you can’t even tell anyone in this house hold smokes.. you just can’t.. that’s how good this thing is.. my clothes haven’t had that smoke smell in a long time. I love this thing and if I move into a bigger space I will definitely be buying another one. The price is also very convenient and affordable given that this thing is great quality. I highly recommend and I don’t even get paid for my review. I just thought I’d let someone know! If you’re lookin! This one here is for youuuuu! When it’s on it sounds like waves. It puts me to sleep.

Good product overall
I’d say my only complaint about this item is its size. It’s kind of large. But it does work efficiently. I run it in my “office” (fabric room) to prevent any musty smells. It works very well and keeps the air fresh. Overall, it’s pretty quiet, so that’s no bother.

Clean air with a touch of white noise
This device works great during cold and flu season. I set it up in my kids room to help keep the germs down. My daughter complains about the device and calls it’s noisy. My son on the other hand appreciates the sound and says it puts him to sleep. I do notice the air smelling better in my son’s room. He also likes the UV light because it looks cool. The filters are very easy to find at many local chains since I forget to plan ahead.

Great Air Purifier
Works great and is very quiet. It came highly recommended from the website Mold Help For You, run by an expert on mold, mycotoxins and remediation. It’s a great price, too, and the replacement filters aren’t too expensive.

Great quality and worth the price
Love this purifier, great quality. I automatically saw results in the air quality. I could breathe easier and wasn’t sneezing as much. It is quite loud on high setting but not too bothersome. I sleep with it as my white noise lol. The size isn’t too big so it doesn’t take up much space.

Great air purifier
I bought 2 of these. They work really good. The filters last quite a long time. You have to vaccume the front filter about once a week. Not a big deal to do. It will prolong the life of the filter. The filters are a bit expensive. They are very easy to replace in the air purifier.

Noticeably Fresher Air at Home
I bought this purifier mainly for allergy relief and to help with pet dander, and it’s been working really well. Within a day, I could tell the air felt cleaner and lighter, less dust settling and fewer sneezes. It’s quiet on the low setting, and even on higher speeds it’s more of a steady hum than an annoying noise.The HEPA filter does a great job with everyday allergens, and I like having the UV-C light option for an extra layer of germ protection. It’s also compact enough to fit in a corner without taking up much space, but still strong enough to cover a large room.Filter replacements are simple, and I appreciate the reminder light so I don’t have to keep track. Overall, it feels reliable, easy to use, and has made a noticeable difference in air quality, especially during allergy season.
