Helps clear my sinuses
Color: White, Color: White
As someone who would constantly wake up in the middle of the night with a cough and stuffy nose, I have had this air purifier for 1 day and have already slept through the night with completely clear sinuses! It is almost noon the next day and I have not had to blow my nose or clear my throat once, which is unheard of for me. My stuffy apartment smells better too. I haven’t even dusted or vacuumed yet and it is already making a huge difference in my daily life, I can’t wait to do a deep clean on top of it! It really works and is 100% worth the money!

No complaints
Color: White
I have purchased three of these air purifiers. We keep one in each occupied bedroom and one in the living area. I appreciate that they don’t take up much space. They are easy to operate and are aesthetically pleasing enough. We purchased to help with our dog’s dander and any loose mold spores that may be in the air. I put one in our laundry room for awhile because of the musty smell that hung in the air. The next time I walked in there I could feel the difference. It smelled lighter and felt drier than before. The first two I began using at the same time, and I’ve had to change one filter so far. It lasted approximately 2 months. It was dirty when I removed it which indicates it is functioning properly. They are also pretty quiet. I can sleep with it on low next to my head without issue, but it does have a sleep mode. Overall, I have no complaints and would recommend for an affordable air purifier.
Update: The third one we purchased separately from the first two. When the unit is ON but not RUNNING it has this incredibly high pitched frequency that is similar to your ears ringing. I haven’t noticed any issues with its functionality, but I definitely make sure I unplug it when not in use.

Great value for $$$
Color: White
This is a great air purifier! We had some work done in our master bathroom & really wished we would have purchased this sooner! We lived in the house during the remodel, but so much junk is circulated in the air since demolition of our 60 year old home! Both my husband & I have had respiratory infections! Glad this helped clear the air so we could sleep better at
Night!!
