  • Why UV-C Technology?
    UV-C light technology is proven to kill common germs on surfaces, in the air and in water. It is highly effective at penetrating thin-walled viruses and bacteria known to cause: staph, pneumonia, tuberculosis, bronchitis and meningitis. The light alters the genetic structure of the germs and they die.  

  • Do I need to replace my filter?
    Yes. It is recommended that you change the Combination Filter every six (6) to nine (9) months depending on use.

    How long is the warranty?
    The warranty is a 5-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 six (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.

Great for larger spaces!

Love this cleaning system and can definitely feel the difference in our mostly inclosed living space and so glad you offer these working solutions for tortured nasal passages and sinus - thank you!!!

By: Andy

The product is excellent!

The product is excellent, works as described, sold for a reasonable price, and of premium quality.

By: chefziti

I love this product!

I have been using my new purifier for 2 weeks not and I love it! I use it in my bedroom while I sleep - I suffer from bad sinus issues and this has definitely improved my sleep quality - my sinus's pool a lot less. The air actually smells clean and fresh all the time! Gonna buy at least one more come fall for the living room and kitchen!

By: satisfied customer

Love the # in 1 Air Cleaning System!

Love how it can remove the odors from cooking in a timely manner. Helps with dust also in my house. I have two (2) in my house.

By: NaNDa

I would buy this product again with closed eyes!

Excellent product. Now I truly have quality air at home and it is really quiet so I can turn it on at night and sleep like a baby. I am really happy with this choice =))

By: GiGiSan

This is a wonderful machine

I have had my AC5250PT for at least 5 years and it has saved my health as I was unable to stay well before I purchased it and previous to getting allergy injections 2 once a week for 3 years. I can surely tell the difference and would recommend it to anyone that is allergic . I have many environmental, pet, and pest issues and cannot give enough praise to my purchase!!

By: Dessert Rose

My house smells cleaner

I am so happy I made this purchase. I have 2 large dogs which can cause my house to smell dirty no matter how well I try to keep them and the house clean. I enjoy being able to set the timer so it is turned off when I get home from work. I would have given it a 5 star rating but the noise does bother me. It's not a bad noise just a white noise and maybe I'm not used to it yet.

By: Val

Love it!

Love it! Much quieter than my previous air filter and love the UV. It is a bit loud on the highest setting while trying to watch tv in the bedroom, but perfect on number 3 and put up to 5 during the day. We have pets so it's been working magic for my allergies. Will be buying another one for my family room.

By: Robert

Finally...no more allergies.

This product has saved me from the dread of allergies. I would wake up sneezing and coughing nearly every morning. I could never get a break. Once I bought this it was like a miracle I can wake up and not feel like I'm living in a allergy farm. Great product! Highly recommend for anyone, also a great way to help children with allergies. 5/5

By: Debbie

Love the 3 in 1 Purifier

I purchased the machine for my house and I love it. Family members would comment on the clean smell my house had. I purchased family members one as gifts (total of 4). I also purchased a second one for my basement. Now the family members are purchasing their second machines. We also have one in our business.

My only complaint ...the fan is a little loud.

By: Shirley

Wonderful units

I now have two of these on the main level of our home and will most likely purchase another for our basement level and perhaps a smaller unit for our bedroom.

Since these are in the main part of the house (2 separate locations) noise really isn't an issue. If it becomes one I lower the speed to accommodate what is needed and turn up later. I use the UV most all of the time and leave the units running 24/7, one at the highest level, the 2nd one is on a lower level.

We have pets and this seems to help pet smells and with my allergies greatly. I also vacuum and clean the filter and machine(s) monthly, but always replace the filter every four months.

To say the least I love these units.

By: Lynn Turcotte-Schuh

Allergy buster

My two month old daughter and I were having trouble with constant sinus issues and coughing. We got this product in hopes of getting the pet hair and fireplace door out of the air. Since running this purifier 24/7 we have both had a significant decrease in symptoms. The unit runs quiet and we have even had several occasions where sick people have come to visit and neuter of us has caught the illness (we had the UV running in the room). We will be buying another unit for the nursery.

By: Jackie Gran

Glad I bought it.

The fan is a bit noisy at higher levels but fine at medium to lower levels. I can tell the difference in the air quality with the unit. I love it.

By: KSrB2000

Great for alergies

I am allergic to dust and spring. I used to wake up barely able to breath my nose was so stuffed. Now I sleep through the night, wake up completely clear, and feel way more rested. It is super bright so I used LightDims to block the LEDs. Some may also be annoyed by the noise. I recommend turning it on at the lowest setting then slowly raising it to 2 then 3 over time to ease into the noise. Now I actually prefer the white noise to nothing.

By: Matt

Very good

Our house is very dusty and this has helped with getting rid of some of the dust. I was a little disappointed as I thought it would collect more than it did. It is very quiet though and I really like the sleek black look.

By: L. Syler

I run them constantly

I purchased two of these. The first day I ran them and left the house, I noticed such a clean smell when I came back home. I don't notice it anymore but I think it is just because I am used to it now. I put one in my son's room too. I probably notice the biggest difference in there as he is a teenage boy. They definitely work better in smaller bedroom sized rooms. I was very worried after I ordered these and saw the reviews on consumer reports. They were pretty far down on the list. But after owning them for several months, I would definitely buy again and recommend them to anyone.

By: E. Davis

Great for guinea pig stink

We have two guinea pigs in a large cage to which I developed an allergy. Within hours of plugging this in, the room was odor free and my breathing dramatically improved. The unit is a little large but sleek looking. We tucked it next to a dresser and it's fine. We have only has this for one day but so far, great product!

By: G. Weaver

quiet and works great

allergies have all but disappeared inside. bought one for upstairs and one for downstairs. we leave it on the 2nd lowest setting. can hear it running but not an intrusive noise.

By: the one to know

Great Product

This air cleaner works great, I keep it running 24/7. I noticed that I breath easier now since I started using this system. I bought one for my sister and niece, since they liked how easy it was to operate. I would truly recommend this to a friend.

By: Janet Smith

Cleans the air and the air smells

We move this air cleaner from room-to-room and can actually detect the air is lighter and smells cleaner after running it. A home or office shut tight needs a purifier like this to take care of the air quality. We also enjoy the white noise when the fan is on low. The Guardian is easy to operate and easy to use...don't want to be without it.

By: Terry L. Miller "Doctari"

good product

I go this as a second heap filer, one for the bedroom. I brought a different product first for the living room, with said it was for pet owners. It cost more then this one, but this one is just as good.

By: Laura

Very helpful for Allergies

This filter has been invaluable at reducing the allergens in our apartment and greatly increasing the air quality. Definitely worth a try.

By: cesca86

Necessary for a pet filled home!

I love this air purifier so much that I ended up buying a second one to use at work. We have 3 cats, one of which is a Himalayan who sheds tons of hair all over the place, so this is really necessary for us to minimize the hair and dander. I also love the UV light feature on this and feel like no one in the house has gotten sick since getting it. For work it is great because I work in a small dental office and sometimes we have patients coughing and sneezing, so I keep this behind my desk and this helps reassure me that at least some germs are being filtered.
But the one reason that proves to me that this works beyond doubt, is that one of my cats suffers from allergies that cause her to scratch herself until she sometimes makes herself bleed. When the air purifier is turned on her scratching stops and her eyes are no longer runny. On days that it has not been turned on, her scratching starts again.
On the highest setting of 5 the fan is a bit loud but on setting 4 it is perfect and I easily sleep with this right next to my bed. The sound is actually very calming to me and I like sleeping with it on.

Great...room smells clean

I bought this because the pollen lvl this year is pretty high....Plugged it in and pushed power....nothing. After checking it out, I found the screws that hold the inferred bulbs cover were not down tight enough to activate the safety switch.
there were about ten minutes of me being very pissed off...but after fixing the cover issue the unit works great. The IR bulb will raise the temp of the room given enough time....I see it as a minus as I run a little hot. The filter portion works great and the air smells cleaner! The down side The LED and display are very very bright....I wish it had a dimmer knob, switch.....I have a piece of tape over the LED and put a cover over the display....when I say bright I mean...your not sleeping in a room with this thing unless you do. the fan on top level is loud ish but you can tune it out, I run mine on levels 2 and 3 most of the time. I am happy with the product and would buy it again.

We have 2 labs. They are only allowed in our family room. They are fabulous pets, but dogs come with all the associated hair, dander, bacteria, etc. I am sick of my family room smelling wretched. We keep our animals clean & well groomed by the way. In addition we have 1 lab who passes gas frequently. This Air Cleaning system has met & exceeded all my expectations. My room smells fresh & clean. Air movement is great. I believe our air is also healthier. A must have if you have a pet or pets.

By: JM

Good product

We love it. Since we bought it, my son stopped coughing every night. It is also helpful for those with sinus problems. I will definitely recommend it.

By: JL

Love it

I've been using this for almost a year now. Fantastic!! If we leave for awhile and it's not running, we return and I'm sneezing and have watery eyes. I turn it on and within an hour I feel much better. We have it on our first floor which is a wide open area of 500 square feet with open hallway to stairwells to basement and second floor. I usually leave it on 3 as well. Sometimes I have UV light on, sometimes not. If it's been off for awhile(days), I crank it up to 5, turn the light on, and my allergies disappear.

I've been blowing out the filter myself since I bought it. I think I should replace soon. Is it just the 5000 series filter I see here on Amazon or is there a different one?

By: Texanblue24

One of the BEST air filter system!!

This really does work great! My son has so many allergies & has asthma so I kept looking for something to help him! This was all he needed!! His allergies are almost all gone in his side of our home & he's able to breath a lot better! I'd recommend this air filter system to everyone who truly wants to breath in cleaner air & it kills germs so less sicknesses!! A must buy!!

By: Bear

I can finally sleep!

I've had this for 2 months now and am very happy with it. I have severe allergies, asthma and sinus problems. Since having this my allergies are about 75% better in the house. I used to take Claritin D every night now I take it a few times a month or when I know I'm going to be around a lot of irritants like at a baseball game.

Before this my nose was stuffed up most of the time and I would only get 2-3 hours of sleep at a time so I was waking up a few times a night and had to sleep with my mouth open to breath. It did take me 2 days to really feel the difference. I think due to the weather changed a few times before this arrived which is when my allergies are at its worst.

I have this on my side table in the bedroom and have it blowing in my face. It is quite big but I do better with it blowing in my direction.

I bought this after reading reviews of the other Germ Guardian air cleaners, but this one has 5 speeds instead of 3. Speed 1 and 2 are really quite, but I do keep it on speed 3 most of the time. I do have to sleep with some noise. I put it on speed 5 during the day to help clean the air better and down to speed 2 when watching tv in there.

The blue light does not bother me...probably because it is higher up instead of on the floor, but you can turn it off if it bothers you.

My bedroom is 132 sqft with a sitting room right off it with just a doorway no door that is 115 sqft and I have a cat that likes to throw the door open a lot of nights. So this air cleaner has a lot it has to deal with. It is rated for up to 193 sqft.

I am vacuuming the filter once a month to hopefully make the filter last longer (got this idea from a review of one of the other Germ Guardian air cleaners). The manual says the filter will last 6-8 months.

Right now I am searching for an air cleaner for the living room. If Germ Guardian made one for 300-400 sqft I would get it for my living room.

It feels good waking up being able to breath and no sore throat.
