GermGuardian HEPA Air Purifier for Home, Large Rooms up to 1760 Sq. Ft. with HEPA Air Filter & UV-C Light, Zero Ozone Verified, AC5900WCA, White

I have tried multiple models, Oreck table top, Vornado Hepa & very expensive Molekule. Finally I subscribed to Consumer Reports and this brand (not specific model) was in top 2 of their list. We also wanted something with UV germ protection, so the price seemed right to give it a try. Seriously, Molekule was 4x this price & rated at 20/100 by CR vs this brand at 80/100.On the first day, I closed our bedroom door & put it on full power. I have terrible hay fever every spring. I just wanted a nap without waking up breathing through my mouth and miserable. When I entered the room 2 hours later (the room is about half the size this model covers, so 150-200 sq ft), it smelled different, very crisp, almost like being outside after it rained or an ice rink. I took a nap & 90 min later I woke up and was amazed to take a full, deep, bottom of my lungs breath. That never happens when sleeping for me in hay fever season. Since then, I've had the same results, all night long, as long as room is sealed by closing door.Yes, it's loud. There's no question on this and if you want something super quiet at full speed, look elsewhere. We like the white noise & even have an app we play for our son to help him sleep with waves, rain or a fan sound, so that is a plus for our family.And fair warning, it does seem to generate cool air. It's winter now & with our door closed the single vent for the furnace in our room with the door closed isn't up to the task of heating the space even without the air purifier (with bathroom + walk-in closet). This device pulls in air & blows it out strongly on full power. It was enough to mean we had to move it farther from our curtains so it wouldn't suck them in or blow them around so they fluttered. It's a strong filter which could be a big plus or minus depending on your needs. I wouldn't recommend it for a Zen meditation space, spa or massage room where you seek silence.Also, other reviewers aren't wrong about its ability to get rid of strong smells quickly. I'm not sure which air purifiers in this price range & sq ft size would. Give it time and it will eliminate odors, smoke, etc. much faster than no air filtration. We have a 1400 sq ft home that isn't well sealed in main living area (dog door, front door doesn't seal tight, windows simple double panes), so it isn't as remarkable except in bedrooms with closed doors. We bought two for a big room and main area + a few small ones for other bedrooms, then close doors to rooms we're not in, etc. With the right ratio of devices to sq ft, it's exactly what it claims. It does need to be on full power constantly to achieve the room size stated, but that's true of all air filtration systems. It's declared clearly in all the product materials and industry standards.After many models, realistic understanding of what home filtration options available can do well, I can definitely say this one is top notch.

If you're struggling with severe mold allergies—especially to the dreaded black mold—you know how life-altering the symptoms can be: eye irritation, difficulty breathing, and even windpipe constriction. After Hurricane Milton hit Florida, I faced a serious black mold problem in my home. The issue persisted despite my efforts to tackle it with a DIY mold remediation kit and physically removing mold-infested materials like walls. I knew I needed a more effective solution.I tested several air purifiers, including Electrolux, Silver Onyx, Blueair, IQ Air, and Germguardian with UV-C light. After a full day of running the Germguardian purifier, I finally found relief! The difference was night and day—I could breathe again, and the irritation I had been dealing with was gone. Germ guardian outperformed every other purifier I tested and gave me the peace of mind I needed.What’s even better? Germguardian doesn’t come with the hefty price tag of brands like Electrolux or IQ Air. The filters are affordable and easy to replace, so I don’t have to worry about costly ongoing expenses. And the UV-C light feature? I tested it thoroughly and found no ozone scent in the air, making it a safe and reliable choice for anyone dealing with mold allergies.If you’re battling black mold or mold allergies, don’t waste your money on overpriced purifiers. Choose Germguardian—a practical, budget-friendly solution that truly delivers. It’s time to breathe easy again without breaking the bank! Trust me, you won’t regret it!

[PICTURE: it may look like a pointless dark photo, but it shows how dim the On/UV lights are in the dark. Taken from above, front-angle.]Have had various air cleaners ranging from small wall outlet units to several brands/styles of tower designs. This is the biggest and fanciest unit we've had. It can move serious amounts of air, or run very quietly -- we do the latter and bought it since usually large fans can move more air with less noise and better sound tones. Indeed, this is the quietest filter fan we have on low speed (it's right behind us while watching TV and I feel no need to "OCD" turn it off / never notice it) and has no weird tones to it like many of the small-fan tower designs have/develop. The air sucks in all around the nice looking front so you can set it against a wall or corner and have the "correct" side facing into the room. Air vents out the top so it sorta radiates and blends into circulation rather than blowing at you or your stuff.The controls are responsive and easy to understand at a glance, makes a pointless but soft/pleasant noise when buttons are pressed, and my favorite part is you can turn off most of the lights using an included light button. At minimum, you have a single light indicating the unit is running, and a 2nd identical light if the UV bulb is on; both are small, dim, and indirect, not casting a blue spotlight on the ceiling like a lot of cheap consumer devices. I'd probably still tape them if sleeping but most people will probably find them very livable in a bedroom. If not used in a dark space or if you want a (blue... not great for eyes in the dark) night light, it also has an attractive "ring" light that bleeds through a translucent portion of the front plastic -- looks well designed/integrated, premium.The silver/white gloss finish is attractive and unlike the vast sea of shiny black plastic products, does not show fingerprints / dust at all. Does not develop an ugly "micro-scratch" texture either. All of which is to say... It doesn't just look nice the first 5 seconds before you smudge and scratch it getting it out of the box, but still looks brand new after months of use.The filter inside is about 2/3 the size of our AC air intake (a lot of filter...) and has a pre-filter you can vacuum off to extend the life of the expensive main filter. The filter fits snugly. I don't notice much gook collecting around its seams where air leaks by -- a problem on other units we've had. After 4 months running 24/7, the UV light hasn't burned out and the main filter looks good beneath the pre-filter which gets cleaned about every 2 months. Looking at the filter now, we'll probably get a full year out of it or more. I've had towers with finicky UV lights that burn out often and will report back if that ever becomes the case with this unit.The unit is set up next to the condo of a pair of small furry pets, in a house with renovations going all the time... so it has plenty to be extracting and is doing a great job so far. Smells and dust around it are noticeably better. As with all products like this, you may want to research the "ozone" output from the UV light and decide if that's good or bad for where you're placing the unit.Overall, this is my favorite air filter/UV cleaner we have had over the years. Quiet/pleasant, nice looking/looks last, well built, and can move serious amounts of air when you want it to. Though it's wider and surprisingly thick compared to tower designs, it's a much more efficient use of space / more cleaning for the volume than the tower designs -- if you can budget it and physically fit it.
