Product Description GermGuardian HEPA Air Purifier for Home, Large Rooms - 743 Sq. Ft. with HEPA Air Filter, UV-C Light & Odor Reduction, AC4825E, 22" Tower, Gray Brand Story By Germ Guardian

Review: 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****************************** 12/2/2012 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.
Review: Excellent - We've had many different air purifiers/filters, and this is by far the best we ever had. I'm sure if you pay twice as much, you might get a better one; but this does exactly what it says. Our home smells and seems cleaner, and it really can clean the air in a medium to large size room in under an hour. Very simple 3-speed dial, and a one touch physical button to turn on/off the UV light. This makes it likely to be more reliable and you don't need a Phd to work it. lol It also is designed with aesthetics in mind, it's actually kind of pretty. We haven't had to replace a UV light yet, but replacing filters is as simple as it gets, plus the first filter can be washed to save money. Not a complaint or flaw at all, but when you position it, the air does not blow straight out but at an angle. And for those concerned about noise... the low speed is very quiet, medium speed is not unpleasant, and high speed is only loud if you are near it. I bought a second one and may buy more.

## Questions & Answers

**Q: Can you just wash the filter and reuse it?**
A: The filters are not washable. They will need to be vacuumed off once a month and replaced every 6-8 months. If further assistance is needed please contact us at yourfriends@guardiantechnologies.com or at 866-603-5900 X213 M-F 8:30-4:30 EST.

**Q: Do these produce harmful ozone because of the UV light technology?**
A: It is my understanding that the addition of the titanium dioxide component catalyzes everything into water vapor and CO2 while also boosting the anti-bacterial/viral qualities.  However, I have never replaced the UV-C light so I haven’t looked to see how long the titanium dioxide component lasts. (Anything that catalyzes has a “shelf-life” so to speak because all the material is used up.) Good question!

**Q: I just purchased a replacement filter flt4825.  the new filter fits however the unit will not turn on. any advice?**
A: Check the safety switch under the bottom edge of the filter, be sure that the filter is engaging and pressing the switch down all the way.  (also, the latch from the back panel needs to engage another safety switch)  If you need additional assistance, contact yourfriends@guardiantechnologies.com or call 1-866-603-5900

**Q: If I buy the two-quantity pack, do they come individually packaged?**
A: Yes, each unit will come individually boxed in one larger box. If further assistance is needed please contact us at yourfriends@guardiantechnologies.com or at 866-603-5900 X213 M-F 8:30-4:30 EST.
