Review on Medify MA-50 Air Purifier - H13 True HEPA Filter, UV, 1100 sq ft Coverage - Smoke, Dust, Odor, Pet Dander Remover - Quiet 99.9% Removal to 0.1 Microns - White, 1-Pack by Brooke Abrahams

I bought the Mediify MA-50 air purifier during Revain Prime Day this year (2021) and have been using it for about 3 days. I noticed that level 2 of this air purifier makes a vibrating sound like a fan inside is shaking and the whole machine is shaking. The other steps 1, 3 and 4 seem to work fine. No idea why it only vibrates and wobbles in the second step. It would make more sense if he trembles on a higher level, for example on the fourth. But my other air purifier (Winix C555) that I've been using for over 2 years doesn't make any vibrating noise even when I set it to a higher speed. I chose this product over other brands because: 1. I found the Medify air purifier in my dental office and wanted to try it as it is used in the doctor's office. 2. I was looking for a reliable and practical air purifier with the function of killing virus or bacteria and with greater power. The one I used covers 360 square feet. ft. This covers a room up to 1100 sq. ft. Walk in just 30 minutes, 550 sqm. feet in 15 minutes. I wanted to use this product in my living room + kitchen + dining room (it is open plan).3. There are almost no negative reviews about this brand. All day I searched and read reviews about this brand. After reading reviews from other consumers, this helped me in my purchase decision. After using it for 3 days Here are my thoughts.1. I like that the lowest level (level 1) is very quiet. At first I wasn't sure if the machine was on or not. It's very quiet as you can see in my video above. In my opinion it will be useful if you want to use this air purifier 24/7.2. I was concerned that this air purifier doesn't have the automatic odor detection sensor that some other brands have. Since I am very sensitive to odors such as food, human body odor, pet odor, etc., an air purifier must remove odors very reliably. Even though this product doesn't focus on odor removal, I think Mediify MA-50 is great for odor removal as well. I cooked a lot at home which made it smell strongly of cooking, I put this product on level 3 for about 10-15 minutes and the smell was gone. To be honest, I think this fact is what made me love this product the most out of all the other benefits of this product.3. Not a remote that I often use with another brand (Winix C555). It's inconvenient to set or change the mode, especially when I'm lying in bed or cooking in the kitchen. It would be much better if they add remote control or Wi-Fi capabilities.4. There is no handle or part that I can easily pick up and move. It's not very heavy, but has enough weight that you have to be careful not to drop it while carrying it. While I didn't plan on carrying it around the house much, I do enjoy using an air purifier here and there around my house from time to time when I feel like the air in the room needs cleaning. Conclusion: I'm not sure I'll keep this product as I'm concerned about the vibrations this machine generates. I might want to return it even though I love some of the great features of this product.
