GermGuardian HEPA Air Purifier for Home, Large Rooms Up To 743 Sq. Ft. with HEPA PURE Air Filter, Air Quality Monitor & UV-C Light, AC4880B, 22″ Tower, Black

It is worth every penny!
I love this Air Purifier. It shows the AQI. If you put it on Auto, it will go on and off and different speeds as needed. It is quiet, although the highest speed is louder but not so much so that it interferes with hearing other things. The UV-C light cleans bacteria, viruses and mold. It is easy to use very simplistic directions. The quality of air is great. It does take out odors. Very powerful at cleaning air and replacement filters and lights won’t break the bank.

Great Air Purifier At A Descent Price
We had a small kitchen fire which resulted in a lot of smoke which resulted in a bad smoke smell which infiltrated all fibrous things in the house. I ordered this air purifier based on the reviews and the price point of the unit. Out of the box this can’t be easier to set up. You just plug it in. The quality of the unit excellent and of course it’s very portable. It even has a space where you can grip the unit to pick it up. The light level is good and bright and there is a way to shut the light off if the unit is in your bedroom which is a thoughtful touch. The unit is very easy to learn to use and so far we have been very happy with this purchase. I have noticed a difference in the air quality in our home since getting this unit. If I had the money I would purchase another unit for the upstairs. It’s really that good.

I liked it enough that I bought two. Check with camelcamelcamel.com for the best pricing.
I bought one and then bought another. They work great!The only thing I don’t like is they actually blow air towards one side. Way off to one side. The air does not come straight out the front of the unit. If you want the air to blow a certain direction, you have to turn the unit so it’s facing quit a bit in a different direction.Both units seem to measure particulates the same. TThey are very quiet.The sleep feature is great! It kicks down to it’s lowest speed and all the lights on the unit shut off. Touch the buttons and it comes out of sleep mode.As far as any heavy use? My oven smoked really bad one night and I brought the unit into the kitchen to combat the smoke. Normally my smoke detector would go off, but the filter managed to get the smoke under control before that happened. When I turned it on, the smoke made the particulate measure go up really high. It does a pretty good job of eliminating kitchen cooking odors. My house is very small and when I cook, everything can end up smelling like the food. That doesn’t happen anymore.

5 stars until it stopped working 2 months in.
This air purifier stopped doing its job after just 2 months. I replaced the filter thinking that might fix it, butnope. It still doesn’t actually purify the air.That’s not just frustrating, it’s a big deal for me. I’m on permanent oxygen due to lung damage, so air quality in my home isn’t a luxury… it’s something I depend on. I bought this hoping it would make a noticeable difference in my day to day breathing. Instead, it barely lasted long enough to matter.For a product that claims to handle large rooms and improve air quality, the reliability just isn’t there. It feels like a waste of money, especially when you’re counting on it for something important. It’s actually in a fairly small room.The positives on this are that when it worked it was fantastic, I could tell the difference. Its very sleek, easy to move, filter change was easy, the loudest setting is actually a bit soothing to me, and had wanted to give this 5 stars until it stopped working!It of course broke after I was able to return it, and no words back from the company that made this so I cake here to warn others!
