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!
When first opening and setting up the device, it was pretty easy and straight forward. It took less than 5 minutes to set up and the instruction booklet was concise and explained some important things about procedures when operating. The warranty period is pretty substantial which gives good piece of mind. Registering the product online was pretty easy and took less than 5 minutes. It is very quiet even on its max setting which seems to work pretty hard. We just recently got a cat which I am allergic to and it is already clear the device is helping clean up the allergens in the air. Since getting the device over a month ago, it has noticably helped when turned on.
