Review Image by Sandwiched In Between Sandwiched In Between
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****************************** 12/2/2012 Hi 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 6/26/13 We 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 11/13/13 Unit is still working great! We added a second one earlier this year, and pleased with both! =) ***********************************Update 06/29/14 Both units are still going strong with no issues. Still helping with our asthma and allergies. ... show more

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. ... show more

    • Good product overall
Pattern Name: AC4825 white 1 pack
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.

UPDATE. PURCHASED 2017 NOW 03/2022. Unit is still running strong. I have not had any of the electrical issues that some others seem to have. Since my last review I have purchased 2 more units and those are working fine as well. I have also completely disassembled the first unit and cleaned it all out. I removed the little switch lever that can tell if an authentic filter is inside it. (Just disconnect the wires on each side of the switch, remove switch, crimp the wires together, done). By using my own filters (see below) I have saved enough over the last 3 years not buyimg official filters that this and the other 2 units paid for themselves. SIDE NOTE: the official black pre filters are expensive as well. You can search here on Amazon and purchase a large 5ft by 5ft sheet of the stuff and cut your own out to size. ORIGINAL REVIEW: I have had this unit for almost a year now. It's still very quiet and the fans run strong. It is running at least 12hrs a day. The black pre-filter only killed odors for about a week. Any replacement pre-filters only work on odors for about a week as well. I just vaccum and wash mine. The main hepa filters are very expensive to replace if you do it every 3 months like your supposed to. I just purchase the largest 3M filters (2 pack) for 18 bucks at Lowe's. You can cut 5 perfect fitting filters out of one. On the bottom of where you place the filter in is a little trip latch you will need to tape down so it thinks it has an "authentic" filter in it. ... show more

    • UV cleans the air
Pattern Name: AC4825 black 1 pack
Awesome air filtration with added UV light. The fan is strong for its size, and the design is pleasing to the eye and not bulky. The noise level even in medium is light and over time you dont notice its even on. I was so shocked at the low price for what this delivers.

    • They work!
Pattern Name: AC4825 black 1 pack
My room is a decent-sized second master bedroom, and I have 2 of these in my bedroom. I've had them for over 4 years, and they are still doing a great job. I'm super impressed with these Purifiers. I've tried different kinds of filters, and all work great with them. I buy my filters in bulk when they have a good sale on them. The purifier helps get all the dust, pollen, and any odors. I have 2 big dogs, and they're not very dirty dogs, but whenever they go outside and play and come back as wet dogs, the purifier gets the odor out. ... show more
