I just purchased this air purifier for my daughters allergies and asthma symptoms. Since it’s only been a day or two I cannot comment on the effectiveness quite yet but the general use is, easy and self explanatory. Only issue is for people who use reader glasses, I think the words identifying the buttons should be bigger or bolder so you can see them better. But, the simplicity of use is a 10!
                    The device is super quiet on fan option 1 & 2 but 3 is much louder which is odd relative to levels 1 & 2. If it works ten times faster on that higher louder fan level, then it’s a non issue for me.
                    It’s currently in an 10x12 bedroom so we will see if it’s capable of eliminating allergens and help with air quality. So far I like the device itself but again we will have to wait to see how long filters end up lasting and ultimate durability. Unfortunately you just can’t gauge that right away. As of now, I like it and give it a 10 out of 10!
