Customer Ratings & Reviews

Excellent Air Purifier. In my opinion, it cannot be beat for cost/performance, and it runs very quietly. This will be my 3rd Germ Guardian AP5800W 19 unit ordered from Best Buy. We have 2 cats, 2 dogs (all indoor pets), and these units really do the job!

Wonderfully made air purifier! Simply remove the plastic wrapper from the filter inside the unit, insert it back in, plug it in, turn on the power, tap the “A” (auto mode) and let it clean! After about 2 hours I noticed the cleanliness of my air in my bedroom. Waking up the morning, I appreciate how I don’t have those awful head colds anymore that come along with a congested nose. I purchased this when it was apart of the “Deal of The Day.” This unit is a must buy. Highly recommend!

Works well. Not noisy. Also the filter is large. Great for my allergies. I recommend this for those who live in areas where there is a lot of grass and weeds and the wind flows naturally.

I have it set up in the living room. It works great!

Good for white noise and air cleanliness. My son loves the digital read out to tell him its safe to breathe. He can hold his breath for almost 90 seconds while waiting for an acceptable level to him

Great product- quiet and efficient. Very noticeable improvement in a 300sqft room- there has been a significant reduction in dust and the air quality seems to be noticeably better!

seems to work very well does have a slight smell of it's own though, but does not affect it's use.

Love that it displays ‘air quality’ in numbers and colors, and adjusts fan speed based on the air quality. It let’s me know when the air is good or bad. We had a mold problem, and live in a basement apartment. The landlord was very careless about it despite my autoimmune disease and mold allergy but this eased my mind a little after we took care of things. I use it almost 24/7 in my bedroom. The only issues I have is the filters are so expensive, I have not changed it yet.. not sure if it will tell me when it’s time or not.

Works very well. Easy to set up. Perfect size for my room.

It was pretty much out of the box ready, just plug and play (so to speak)... I bought this one because of the large amount of square footage it can clean for the money. It's a little noisy on high but you wouldn't know it was there without looking at it when it's on low. It definitely clears our air of dander, dog and cat fur, and cooking odors. I'm quite satisfied.

This works great. The display on the front is very useful and shows when quality isn’t as good. When we are cooking or doing other things that cause smoke, it automatically kicks the speed up and shows you a number and then you can watch it go down. I think it’s worth the money. I have another brand in our bedroom and I don’t like it anywhere as much as this one

Easy to put together, runs quiet &, does the job. Well pleased

Purifier works well in small rooms. Definitely helped with my allergies. I find i don’t sneeze much anymore. Thank GOD! We’ve only had it a month and so far, so good.

works well. can feel the difference in a bedroom. on auto setting it is very quiet.

it works as reviewed, and I got a great deal through best Buy! Fast delivery, as promised.

So far has been working well. For me, doing a review of item this soon is never comfortable. Item as described & appears to be performing as expected. For now, will give highest review possible in all areas. If product begins to fail, will be amending review & what lead up to changing review for this product.

Great In so many ways very happy with my purchase love the many different settings you have to choose from . I got it on sale and was well worth it for me

Appears to work pretty good. I have 2 cats inside. Would recommend. Bought it on deal of the day for a great price.

nice air filter; quiet; cool fan; just right for my bedroom

When running the purifier is loud and bulky but performs very well. Keeps a large living room deordorized and particulate-free
