I have this one in my living room and I do notice the air is fresher in that room. I bought the smaller Halo for my bedroom and I am happy with both of them.
I purchased the PureZone Elite air purifier from Menards a month ago. I truly love my new air purifier. I have terrible allergies and this air purifier has helped emensely. It's quiet and I sleep better at night. It's simple to use and lightweight so I can carry it into the bedroom before going to bed. I use the automatic mode. I was cooking bacon and it automatically turned the fan on high to clean the air. I couldn't be happier.
I have had my air purifier for almost 3 months and so far I'm pretty happy with it! There are 3 different settings to adjust the "speed," a UV light, an LED light that changes color when the air quality is poor (red, yellow, green) and some other cool features. I did have an incident where I was cooking and the smoke made the light turn red so it does actually work! In terms of air quality, I truly don't know if there is a noticeable difference as I have no allergies but overall it gives me great peace of mind knowing that the air I'm breathing is cleaner. I would recommend to others!
I am very happy with my new PureZone™ Elite and highly recommend it. I have very bad allergies and they have noticeably improved. It is not heavy or awarded making it very easy to move around the house or put away. I also like all the different setting options available.
