Review on 🐾 Highly Efficient Air Purifiers with Advanced Ferris 360 True HEPA Filter for Pet Dander, Smoke, and Dust by Angela Simmons

So far, so good. It has a compact size which I really like, being able to put it on a desk or on a bookshelf. I have a Winix in the master bedroom, but it's large for my son's bedroom (about 300 square feet). It has a clock, press the M button 2 or 3 times to set the time. The buttons are touch sensitive, they are not physical buttons. has 3 levels (e.g. 1,2 and 3), level 1 is low speed with low noise, but there is sleep mode with even lower speed and noise. At level 3, it is strong (compared to its size). After running for a while, I can clearly feel the difference in air quality. The filter has 2 layers. I think I need to vacuum the inner layer more frequently (once every 2 weeks, like my Winix). Here are a few cons1. At level 1 there is a little noise like air going through a filter (my winix does the same) but not at level 2 or 3. At level 3 it's blocked by wind noise. After solving the problem, I installed it. at level 2 for normal use, at level 3 a few hours before bedtime and during hibernation during sleep (avoid level 1 in general).2. When I just took the box out and did the first run there was a smell of new plastic but it almost went away after 1 day and completely gone after a few days. I suggest running it outdoors or in the bedroom for a while without a filter (to prolong the life of the filter).3. The clock is in 24 hour format instead of 12 hour format, I want to change it to 12 hour format.
