Convenient size, quiet, and seems to work well.I have been using air filters of various sorts for the last 30 years and have a perfume/fragrance free home. The dreo has been the easiest to use air cleaner I’ve encountered. I basically plug it in, set it to auto, and forget it exists.The primary uses are in the kitchen and when guests visit wearing strong smelling clothes, perfume, or other scents. I put an air cleaner in the room and in a short while I can forget the problem existed. I have one permanently in the kitchen to remove the smokey oils that are generated from some meals and it has mostly eliminated the need to open windows to clear the air.I originally purchased three for my home, and a year later got a fourth for one of my kids that was moving out.

The media could not be loaded.  After being disappointed with various air purifiers on the market, I learned my lesson and decided to do more research to find a product that works for me. Dreo air purifier was the best choice I ever made. Some of the exciting features that caught my attention include;1. Small but powerfulLooking at the size of the Dreo air purifier, you might be tempted to underrate its performance. However, once you purchase the product, the excellent performance is astonishing. The air purifier is powerful and cleans your air within a few minutes regardless of your room’s size.2. 4 modesThis air purifier comes with six working modes giving you the freedom to set your preferred mode depending on what you need. The modes include;• Sleep mode: as the name goes, this is a perfect mode to use anytime you’re going to sleep, and you want to continue enjoying the fresh air in your bedroom. In this mode, the air purifying device works without producing any noise that could disrupt your sleeping time. Here the air purifier is super quiet, giving you maximum comfort as you enjoy your sleep.• Auto mode: In this mode, you give the air purifier the freedom to automatically choose the best operating mode depending on the air quality in your room. If you don’t like changing the modes, auto mode will work best.• Turbo mode: This is one of the notable features of this fantastic air purifier. If you’re urgently in need of clean air in your room, then this is your mode. The Dreo air purifier cleans your room’s air rapidly. So, if you’ve just realized some guests are on the way, this turbo mode will come in handy. Besides, the device still produces a comfortable noise level even at turbo mode.• Manual mode: This mode comes with 3 fan speeds, but you have to keep changing the fan speeds. However, you can manually set your preferred fan speed once and keep enjoying healthy and clean air.

I thought I was going to be writing a bad review because I had my doubts the air quality sensor was actually working. I have always had a lot of pets, I currently have 4 cats. The main reason why I got this one was because of the air quality sensor. I know that most air purifiers work to some degree, even the very tiny cheap one I keep in my bedroom. I only know it works because the filter needs changed every few months. First off, it arrived quicker than they said it would. It was supposed to arrive on Monday and I got it Saturday. It was pretty straight forward setting it up. You just unscrew the bottom and pull out the filter, take the plastic off and put it back in. Then you plug it in. I like that you don’t actually have to push the buttons, you just touch. Then for about a minute it scans between red (being the worse) to orange, green and then blue which is the best. Well, it scanned through the colors and landed on blue. To me that was shocking because of the fact that I do have 4 cats. So, I took it to my bedroom where the cats like to hang out on my bed. Same thing, landed on blue. At that point I was a little worried that the sensor didn’t work. I keep a cheap blanket on my bed to protect my bedding from cat hair and dander. I gave that a couple good shakes and within seconds, the light turned red. So it works! I would say it took about 15 minutes for it to cycle back down to blue. While it was doing that, I went downstairs and ran the sweeper in the dining room. When it was done upstairs, I brought it to the dining room. Turned it on and it stopped on red. This time it took about 10 minutes to cycle back to blue. One of the big issues in my house is the litter boxes. I have one cat who never learned to cover up her business. When she poops, you could smell that through the house. I can honestly say that by the end of the day, I can no longer detect litter box odor. I usually do my “spring cleaning” during the winter because I’m busy outside in the spring. I decided to start early. As I washed down walls and dusted surfaces, the light would change from blue to either orange or red depending on what I was doing. The sweeper will make it turn red within seconds of turning it on. I will have to say that I’m very happy with this unit. I think people have to realize that having an air purifier doesn’t mean you still don’t have to sweep and dust. It will not get rid of dust clinging to surfaces. But, once it is in the air it will take care of it and should keep dust down if you do clean on a regular basis. Also, make sure you read the maintenance part. After running it for two days, I did notice some dust on the surface of the unit so I wiped that off. I also took the filter out. It has a fine micro screen covering it to keep the big stuff out of the filter. There were lots of fuzzys on it and I just wiped them off too. During the day I keep the unit in whatever room I’m cleaning and I keep the fan on the highest setting. About an hour before bedtime I put it in my bedroom and put it on the medium fan setting and it’s so quiet I don’t even notice it. The only way they could improve this is if they could put some kind of handle on it to make it easier to carry up and down the stairs. I think in the future I will get another one so I can have one on each floor.

Actually I have two of these. One on the first floor and another in the master room. They are easy to operate and is able to keep the smells and air clean. Recommended.

This has been an awesome air purifier! Included a picture of the filter after about 3 months of daily use. A little noisy on turbo but bearable.
