Love it!

I have had this air purifier for about a month and love it! The highest speed is a little loud but super effective so I turn it down to medium after around 25 minutes or so when I get home. If I get cigarette smoke inside from a neighbor lighting up outside I notice that no smoke is detectable after just 5-10 minutes on the highest speed. It works very quickly in my small apartment. Purchased for fire season in the PNW and for daily use because I'm near a highway and feel really good about the airflow of this model. It also has a beautiful, clean, functional design. I like that I could reorganize the filters so that the pellet carbon filter sits between the pre-filter and the HEPA filter because that order makes more sense to me. Choosing a purifier was stressful because I'm tight on funds and the air quality during fire season is a major concern where I live but after getting a few questions answered kindly and responsively over email I was confident with this purchase and feel really great about my choice. So happy to support a B Corp and have clean air at home!

Still Hopeful

I'm somewhat disappointed in the charcoal filters, which are not really all that effective against the various noxious gases that are emitted from a new laminate floor. I still have to open windows and use fans, otherwise they build up and make the room difficult to occupy. I worry about the weather becoming much warmer in the summer, as it loses even more effectiveness unless I keep the room as cold as possible with AC. I will admit it does do some good, but not nearly as much as I had hoped.

SA 600 Air Purifier

Very nice purifier. Like the way it distributes air around the room. Easy to set up. Easy to move with the handles on the sides. Had a few questions when i first got it gave them a call they answered all my questions. So nice to talk to someone who knows their products and cares about their customers.
