Great Peace of Mind- Almost Perfect
Posted by: dancerathlete from: Orem, UT on
I have been running my air purifier 24/7 for almost 2 months now. I haven't had any problems with this unit.
1) Really cleans the air- after just a WEEK of use, the outer (carbon) filter was covered in dust! Disgusting, but I'm satisfied to know that wasn't in my lungs. I vacuum the filter once a week.
2) HEPA filter. Although I can't actually "see" what it is catching, I know it is helping my air quality! I live in Utah where the inversion pollutes the air on a regular basis during the winter. This air purifier gives me peace of mind, knowing that when I come home I am in a clean air environment. Not only that, but it catches dust mite allergens, pollen, plant spores, bacteria, fungi, mold, smoke, dust..... We are definitely sleeping better at night, not waking up with the usual "stuff" that you have to clear out of your throat in the morning... catch my drift?
3) UV light- peace of mind that the germs that are caught by this thing are killed.
4) Catches SMELL (carbon filter)- I am used to smelling leftovers when I let my pots/pans soak in the sink overnight. Not anymore! I know this works because one time we went out of town overnight and turned the unit off. When we came back, our apartment smelled like soaking dishes/leftovers. A smell I'm glad to be rid of using this unit!
1) When I first got this unit, the lowest setting was pretty quiet. It is noticeably louder now. However, at this setting me and my husband are still able to sleep with the unit in our bedroom at night. AKA not too loud for sleeping (and I used to sleep strictly with earplugs for 2 years straight, so that should tell you something!). Because the fan got louder, I rate this product 4/5 stars. I hope it doesn't continue to get louder. I will update if it does.
2) When we first used it, it did have a "new" or plastic/carbon smell to it. I imagine this was the carbon filter. The smell was gone by the second or third day.
I recommend this product. It is the best Air purifier/HEPA filter you can get for this price range. Obviously if you spend more money, you can get a much better product that will cover more square footage.
**IMPORTANT- the 22" model can be used up to 155 sq. ft. The 28" model can be used up to 193 sq. ft.
Buy according to your needs. AKA, measure the living space you want to use this unit in. In bigger rooms you will need MORE THAN ONE UNIT if you want this product to work effectively. Just an FYI.

Excellent value for the money
Posted by: Adie from: ny on
Finally after reading lot of reviews and suffering from allergies for almost 3 months into this terrible weather of NY, i finally decided to buy this purifier. I was a little cautious as some customers complained about having problem with some units, so i decided to go to store instead ordering online. While in store I asked the representative to turn it on for me so that I dont have to return from home.
Out of the box, just plug it in and and is ready to go. Has 3 settings i,ii and iii. III is slightly louder but at I and II you wont even know if its on. We have a closed living room area and my wife loves to cook and fry things. So she decided to cook as soon as I turn the unit on. And we couldnt appreciate smell of cooked food where the unit was placed and as soon as she turned off the stove we couldnt even smell in rest of the living room area (my living room is approx 500 sq feet). Next morning I woke up without having to sneeze or having a stuffed nose (something very unusual for me). My son suffers from similar issues and he gets frequently sick (almost every month). I am hoping that this unit will continue to impact our life positively

Great Dust Remover
Posted by: Jetski135 from: O'fallon on
We moved into 2 story base house with no upstairs return air, nothing but carpet, and the dust was horrible. Every morning we'd wake up with sore throats, bloody and stuffy noses, etc. We put one in each bedroom and the next day everyone woke up and could actually breathe!! We have also noticed a dramatic drop in dust on flat surfaces even with 2 medium sized dogs. We are going back to buy another one today to put on the main floor. I only wish these bad boys had a little bit better range. BTW, BB has the best price on them, over $40 less than Amazon!

love it. It is not loud, a smooth soothing sound helps me sleep at night. And cleans the air so that I find I don't need to use nose strips as often! The uv light is easily turned off for nighttime sleep (blue light tends to interrupt sleep readiness - mimics dawn). My room never smelled so good, it is really a pleasure to walk in after being away all day and smell the freshness. Smells like mountain air. love. it.

Solved many issues, in just minutes!
Posted by: Nicoman from: on
Wow! What an amazing machine! Recently a new member in the house is smoking, and refuses to go outside. Despite only that one person is a smoker.... Put this in my bedroom, and within minutes I was already breathing better. I could feel my lungs thanking me. I could feel my nose and mouth breathe better. I also own a cat, but never had a problem with his hair/dander. This solved the smoke odor problem right away! A HEPA + Carbon + UV-C light, does wonders to Odor, Mold, Allergy. Even if you think you have none, you'll breathe 10x better with this. Lowest setting is quiet as a mouse. Perfect for sleeping. The nice subtle UV light gives a nice nightlight as well. Good size machine, not too big, not too small. Does job well. This was easily the best $99 spent in over 10 years. Just from sleeping one night, I woke up 1000x times more refreshed and ready. No clogged nose, no sick stomach from waking up to cig-smoke. Do yourself a favor, and spoil yourself with this!

What Good is a Warranty If you Keep Paying?
Posted by: Denverite from: on
I received the Guardian Technologies AC4825 germguardian 3-in-1 Air Cleaning System sometime shortly after October 3, 2015 (shipping date) and put it immediately into service. On December 19, 2015 I took the unit out of service and cleaned it in accordance with user manual. When I put it back into service, the UV light would not come on. Thinking I could have damage bulb by banging it while hot, I ordered a replacement bulb. On about December 27th, I received the bulb and replace the one in the unit. On placing the unit back in operation, the UV light would still not come on. On December 30th I called Guardian Technologies customer service. Although still under warranty, they advised me that at my own expense I could purchase packaging material and pay to ship the unit back to them (also asked me to insure it at my expense) and they would have a technician look at the unit. Let’s recap, unit broke in 3 months and I was to spend my own money to send it back to Guardian Technologies under warranty.

Make no mistake, this has really helped!
Posted by: Sandlotje from: Gainesville, FL on
***************I've only had my unit for 6 days now.******************
So I got the smaller of the two germ guardians because the smaller one was the only one that was in stock at the time; and I was desperate to find something to help my allergies.
I got it and noticed a difference the first night after letting it run in the bedroom with the door closed for a period of around 12 hours. Nights previously were unbearable due to the worst pollen season in years. I also have a dog (does not shed), but I noticed more allergies after I got him. This has really done a lot to help allergies of all types.
Prior to using the Germ Guardian, I was using allergy pills here and there that had little to no effect on me because the pollen has been so overwhelming this year. While I still experience plenty of allergy symptoms, this has alleviated them to the point that I do not have a stuffy nose at night anymore. Without this, I would have continued to have many nights of sneezing fits and light sleep.
As far as odors go, it definitely *helps* but does not eliminate like some of the other reviewers seem to experience. My dog is not quite housebroken yet, and even though I have this running, I still experience plenty of bad odors. Sure they're not quite so bad; I would not base my purchase on the odor control aspect.
Overall, I HIGHLY recommend this. It has been doing a tremendous job of capturing a lot of airborne dust and debris and other allergen-causing pollutants in the air. My nights have been significantly better by just using this unit; but I think allergy medicine still helps to attack the root of the issues.
