I got this for my upstairs hallway to help reduce allergens in my home for my daughter with allergies. We have been using it for a few weeks. My daughter has been having noticeable less allergies and it really helps eliminate smells from cooking and our pets. I really like the different makes. It even has an option for purified heat! Because its near our bedrooms it was important that it was quiet. You can barely hear it running! It's really simple to change the filter and the remote control is really handy. I really like digital display that reports your air quality. We will probably get a second unit for downstairs.
