Airthereal Air Purifier, 315 Sq. Ft.

As fire season has become more problematic, I have obtained several Airthereal air purifiers for throughout the house. They have good features, performance, and appearance and can often be found at a good price. This one in particular does not have all of the features of some of them (no wifi, air quality sensor, UV, etc.), but in exchange it is inexpensive and more importantly, the replacement filters are very inexpensive. This air purifier can move a lot of air, but in night mode it is very quiet (audible, but totally tolerable). Since it doesn't have a lot of features, it is simple to use. I typically use night mode every night while sleeping. One downside is that the night mode light does stay on and can seem bright to those sensitive to that kind of thing, but i have it covered with a post-it note (and the button still works through the paper). During the day, I'll only run it if there is a specific need, and usually on a timer so I don't forget to turn it off. I like having more capable air purifiers for other parts of the house (for example the AGH550 with air quality sensor to respond to cooking and other stimuli), but this one is simple and perfect for bedrooms, plus the filters are way cheaper.
