Why is the red and/or blue light blinking when I first turned on the air purifier and how do I shut it off? The air purifier now comes equipped with indicator lights that automatically blink when it’s time to replace the Filter or UV-C bulb. If the reminder lights are blinking the first time you turned on your purifier, simply reset the system by holding the UV button for at least 3-5 seconds until the reminder lights stop flashing. Your product is now set and ready to go!
Do I need to replace my filter? Yes. It is recommended that you change the Filter (FILTER B/FLT4825) every 6 to 9 months depending on use.
How long is the warranty? The warranty is a 3-Year Limited Warranty. For more detailed warranty information please refer to the warranty section of your instruction manual.
What is CADR? CADR stands for “Clean Air Delivery Rate” which indicates the volume of filtered air delivered by an air purifier. CADR ratings show the effectiveness of how efficient the air purifier is at capturing fine particles from things like tobacco smoke and plant pollens from the room.
How do I know when I should replace the filter? It is recommended that you replace the Combination Filter every 6 months — depending on use — to maintain an optimal level of air purification. When the filter turns from white to dark grey or black, it should be replaced with a new one. If the filter is still white, it does not need to be replaced.
What is UV-C light? UV-C is part of the ultra-violet light spectrum that is filtered out by the earth’s atmosphere. The “C” stands for the particular frequency of UV light that kills germs.
Why is UV-C light so effective? UV-C light is highly effective at penetrating thin-walled germs like viruses and bacteria. The light alters the genetic structure of the germ, and they die.
I have been using this cleaning filtration system every day. The trick is to buy filters and to clean the actual filter every 3 days with a vacuum after a few months, replace the filter. It works amazingly.
Awesome! Does what it says
I just got this and i can tell you from only 3 hours if having i cant tell the difference in air quality in my living room. Smells fresh! Got rid of dog and muggy smell I will definetivly by a second soon. Noise is not loud and kinda soothing
Would totally recommend to anyone to get the germ guardian ac4825
AC4825 air purifier
Awesome air purifier!! I have toxic mold infection and CFS...my apartment is clean...i can breathe...feel my lungs and little by little i am gaining my energy back!! What a blessing...i am very happy with Guardian Technologies!! Thank you!!
Excellent Air Purifier
I have a recording studio in the tropics that would accumulate odor from humidity and electronics. The room is completely hermetic with only an air conditioner to cool, dehumidify and circulate air. It just so happened for a week, my AC went on the blink. The humidity began to creep up and that particular smell of mold/mildew took hold.
I placed the AC4825 on the carpet floor and put it on it's highest setting with the UV light enabled. After two days on the high setting, the unit neutralized the odors and gave the air a crispness I never had experienced before, without the AC functioning and the room at 85 degrees f. With the AC functioning at all times now, I use the AC4825 when I am not in the room and between sessions. It is one of the best investments I have made, especially for its portability and ease of use.
I recommend that the UV light be enabled at all times as this is the device that actually sanitizes the air. Having a spare bulb on hand is always a good idea.
A must for people with allergies or bad sinuses!
Only owned 2 days and WOW!
When I came back from vacation, a family member said the air in my home was "heavy" (they were taking care of my cats). I've spent years with allergies (allergic to everything, should live in a bubble) and horrible sinuses. Every morning spending up wards of 10 minutes blowing my nose, rinsing with saline solution to try to clear out the "build up".. I researched all the different brands and types of air purification available, that was affordable. I ordered this particular model.
It arrived 2 days ago. Within an hour of it being on and running, noticed I was breathing.....easier. After leting it run over night I noticed, my sinuses were not blocked/plugged or otherwise in the morning. It's the first time in years that I haven't had to spend time blowing and rinsing my nose and sinuses! Wow!
This is the 2nd morning, again no sinus issues... and a pleasant surprise, my energy level seems to be increasing! Finally had the energy to workout this morning and only 1 cup of coffee (the normal is 4 cups by now and still struggling to wake up).
So, embracing the new and hopeful norm! Increased energy levels, better sleep, easier breathing and no sinus issues!
Who would have thought?!! (thinking about all of it though, it does seem to make sense!).
Thank you for making this amazing product!
Understandably, devices true performance is typically determined over some time, if there is a need to update this review, or post an "update" I will do so.

Love this product
I have owned this model for about 4 years now. This unit runs 24/7 and I only turn it off to clean the prefilter, or to change the filter or UV bulb inside it.
I am amazed at how much stuff is in the air in my home that I couldn't see. It does such a great job keeping the air clean, and fresh, and literally after using this, not one single person in my household has caught the flu in 4 years. Im not even kidding! That UV light does truly zap that stuff and kills it off. So for my family of 3, plus 2 cats and a dog, we all have been healthy. I am sure that this is one of the reasons that we have been healthy for this long so far.
I just keep it clean and replace the bulb at the appropriate times and it hasn't acted up even one time. I use it on high at all times.
Id highly recommend this item, I used to have the air sanitizer, the taller silver cylinder shaped one, it finally bit the dust after about 6 years of constant use, and I cannot say enough great things about germ guardian products. Id recommend them to anyone!

I LOVE THIS AND SINCE I SMOKE WHAT A DIFFERENCE IN THE AIR WITH THE FLOW. THE SMOKE DISAPPEARS FAST.WITH THIS AIR FLOW IT IS LIKE YOUR AR CONDITION IS ON. GREAT BUY AND NOT SORRY. GET ONE PLUS A GOOD WARRANTY. NOTICE MY BREATHING MUCH BETTER BECAUSE NO MORE STUFFY NOSE AND GOOD FR MY LUNGS ALSO. YOU CAN'T BEAT IT PLEASE TRY ONE CAN'T GO WRONG.
A Great Value
This unit is worth every penny. I am actually surprised at the low cost. We have been using this unit in the smaller bedroom for over four months now without any problems. After the first month, I was amazed at how much dirt, dust and dog hair the germGuardian caught. We have a small dog and carpet all over the house (professionally cleaned once a year, but never had the vent system cleaned in the ten years since it was built.) We vacuum the charcoal pre-filter every few weeks using the brush attachment on our Dyson. It is true that the first few days of being on 24/7, a strong chemical smell was emitted. If you are sensitive, I would recommend letting the unit run in another part of the house until the smell goes away. I also have the Winix WAC6300 being used in the master bedroom, another great unit I recommend.

On the recommendation of my doctor to help with my asthma, I looked around for a true HEPA air filter. This one had the best reviews and is the top seller, but I was a little skeptical. A true HEPA for under $100? It seemed unreal. But this air filter has been awesome. No setup required -- just unpack it and plug it in. It will have a plastic smell for the first 24-48 hours, but it didn't bother me too much. It stays in my bedroom, as I spend the majority of my time at home there. It's fairly quiet on the first and second settings, which provides me with the white noise I need to sleep. The third level is not uproariously loud, but it's too loud to sleep with.
The quality of the air is markedly improved. My boyfriend came over a few days after I had this running and actually took notice of how much fresher the air seemed. My lungs agree, and with the combination of the right medication, I'm breathing better than I have in years.

Love, Love, Love!
This air cleaning system could have actually saved my life. I have lived with cats my whole life, and all of the sudden I became highly allergic to them about six months ago. My asthma became severe, and I acquired sleep apnea. I had to see my pulmonologist regularly to try to control my symptoms since it was too difficult for me to get rid of my cats. 30 minutes after plugging the germguardian into my wall, I noticed the air becoming more fresh. It has been four days now, and I have not used my inhaler once! I can breathe out of my nose and I have stopped coughing! I immediately bought one for downstairs as well. These run 24/7, and they have turned my life around!
a must for allergies, great price!
I have 3 cats. And I'm allergic to cats (they're cute, what can I say!). I've just kind of put up with it for years. I keep this filter in my bedroom, where the cats sleep sometimes and notice a huge improvement! I noticed a reviewer say that they still have pet hair and dander...well, that person needs to clean their house! You can't expect this thing to suck up cat hair and dust off your furniture and bed - you can expect though that while you are dusting and vacuuming, that this thing will suck up little allergens that the vacuum or cloth don't get. I leave it on at night on the lowest setting. Anything higher than that would be too noisy for me to sleep. When I put it on full blast during the day, I walk into my room to clean, crisp air. Don't think, just buy!

Noticed a Difference Immediately!
We were not sure if this would help us with our allergies, but after a winter of very bad allergic reactions, and a double bout of bronchitis, we were feeling ready to try anything. Our doctor said this would be a good idea also.
Apparently, the charcoal filter filters out bad air dust mites, allergens, and things, and then the UV thing zaps other bad stuff dead. Hurrah! It's all very scientific.
It's only been a week, and it's quite a major difference. After the first night, the air smelled much fresher. We have two cats; and before we received this, we had done our usual hyper-vacuuming, using the enormous lint-roller thingy on the couch, washing the curtains, changing the bedding, etc. That did seem to help a bit. However, we do all these things quite regularly (REALLY), even though our two cats our short-hair.
It seems to be more of an allergy problem (we live in TN, and the allergies in this mountainous valley are a hell-hole for everyone- they post allergy alerts on TV).
We put this baby on the "one" (lowest) setting the first night and noticed a real " fresh-air" smell.
The second night, we put it on "two" and it hummed along, cleaning the air. We slept like babies for the first time in ages.
We still have not put it on the "three" setting as I'm afraid it will suck our entire house into the filter!! ;)))
It is very quiet, and it cleans about 155 square feet of air per hour, so we ordered just one. It does have a glowing blue light, so you might not want to keep it in the bedroom at night.
Our shyer cat thinks it is Darth Vader. Both of our cats love to play with the box.
A note: It DOES come with the filter already installed- you do not have to install the filter.
You will pry this from my cold, dead hands.
Germ Care air filter
This product is very reasonably priced and has made all the difference in the air quality of my home. The air is cooler to breathe and does wonders for helping eliminate dust and odors.
I am very happy with this purchase. I was a little concerned with some reviews complaining about it producing a smell.... At first, there is but a clean smell not bad at all.... And it went away after just a couple of uses. It does its job well!

The air is SO much CLEANER!
After reading great reviews of this product, I decided to choose this HEPA filter for my son's room. He had been diagnosed with asthma and pet allergies and is now being treated for dust allergies as well. We have a dog that sheds copiously. This product shipped quickly and required no other assembly than just plugging it in. The unit is incredibly quiet and even when turned on high, just sounds like a fan is running (or similar to a laptop when the fan turns on to cool it down). I didn't notice an overwhelming or offensive plastic smell. The air seems so much cleaner and purified. It sounds weird, but the air in my son's room actually smells "cleaner". I am thinking of ordering a second unit to keep in the main living areas of our home. However, this unit is so lightweight and easily transported, that I have moved it from room to room. I have noticed a definite difference in my sons congestion and coughing since purchasing and installing this HEPA filter.

I did not notice any chemical smell, either in the box or when first running the machine. I set the unit up in my bedroom and can tell a noticeable difference between my living room and bedroom. Sleep is 10x better. I found this one on sale and immediately have been looking for another one.
I can breathe!
I live with a very heavy smoker (2 packs a day). He has not been able to quit so this Hepa system was the compromise. Our house went from a heavy smell of smoke to just a hint of smoke. I can still tell when he is smoking but just barely and I no longer start coughing. The system is very quiet even on high. It has a really cool looking blue light when the UV bulb is on. Highly recommended.

Does the job
Clears bathroom smells like a champ!!! Tip, buy activated carbon filter, place it behind the machine's stock filter for extra odor removal capacity and to extend the life of the HEPA filter.
By: Kaet Echter "Echsentrik"
I recommend this to EVERYONE!
I purchased this about 4 months ago, and I have to say, it has changed my life! I have two large dogs and allergies. Though my dogs don't shed much, they still have dander and they used to send me into middle of the night asthmatic fits. I wasn't sleeping a full night through without a double dose of allergy medicine and an inhaler (and even then it was iffy)...Until I got the GermGuardian. Upon first use there was a little of that "new plastic smell," but it went away after about 36 hours of continuously running it. The first night I used it, I took my allergy medicine, but did not have to use the inhaler. Did not wake up once! The second week after using it, I noticed that there was less dust in our bedroom, and I had been able to take my allergy medicine less and less (now maybe once a week if that). In fact, I haven't touched my inhaler in over two months!
I am going to buy a second (larger unit) for our upstairs living area. I take the smaller one upstairs while I'm cooking if I am making something that is really smelly (like fried fish or bacon) and run it while I cook. It really helps to minimize the amount of lingering odors. It would be nice to not have to move it around all the time!
The best part though...In this yucky cold and flu season, I am pretty sure the GermGuardian kept me from getting full-blown sick! I started to feel a sore throat and stuffy, but it never broke out into a full cold.
I have recommended this item to four people who ordered it, and all of them said that they are noticing a huge difference in the air quality in their home.
***ONE THING TO NOTE*** You have to rinse the thinner filter off about every two weeks (and be careful, it can tear easily). I don't recommend vacuuming it (I tore it up, and it didn't seem to get all the crud out). I usually just rinse it out in the tub with cool water and let it air dry for about 5-10 minutes. It will help prolong the Hepa filter in it.
Does the job, and well
This air purifier does a great job. The air is noticeably cleaner around it, and my problem with allergies have decreased because of it. I also really like the UV setting- it makes me happy to know that germs won't get far in my home. I've noticed no smell of plastic, as mentioned in another review. I've been using this purifier for 6 months.
By: Chandra Faulkner "mama chacha"
so far, so good!!
I just purchased this device and put it into service yesterday to combat the terrible mold issue in our old apartment, and also because we have dust and cat dander no matter how often I dust and vacuum. Where there is a mold flare up, my daughter coughs all night long (and ends up getting sick), which happened two nights ago and prompted me to make this purchase. Last night however, there was zero coughing. The air actually smells and feels fresh and we both slept incredibly well. Its very quiet, sleek looking, and Energy Star rated so I don't have to worry too much about using it 24-7.
The previous review said that it emits a strong plastic odor. That odor is present the minute you take it out of the box, like all new things made of plastic. After running it for about 18 hours, the smell is barely noticeable and I'm sure will continue to fade away. In fact, food odors get trapped in the bedroom every time I cook, but not last night! Its the only room in the house that doesn't smell like the garlicky beef I made for dinner. :)
