The goal of this test is to see how well different air purifiers clean a real room. Not a gimmicky little smoke box, but a full-sized furnished room that humans can actually live in and want to keep clean.
We take an air-sealed room, fill it with a consistent amount of smoke, and time how long it takes for the air purifier to clean the room to a healthy level according to EPA standards. The air quality is measured by the PM2.5 meter in the room, located where a person would be at the desk. The screen is enlarged on the top left corner of the videos.
These are the time-lapse videos showing how each air purifier we tested cleans the room.
"This is a game-changer to the air filtration industry. We have one in the office and one at home. People, both employees and visitors to my home, have asked what I have done to make the house/office feel and smell so much better. I just point to the ASPEN."
"I don't have allergies but when I heard about the Aspen, I thought "who wouldn't want better air to breathe in the home?" I set the machine up one evening. The next morning I could tell a drastic difference in air quality. The air felt crisp which is how I describe it to everyone. I never would have believed it. It feels like the type of air you want to breathe deeply in."
"I have had severe pollen allergies in the Spring for over ten years. I have tried almost everything receiving little to no relief. We are currently in peak season for pollen and the Aspen has far exceeded my expectations! I CAN FINALLY BREATHE COMFORTABLY and RELAX in my home!"
"The Aspen air purifier is amazing. My home is new construction and I've been struggling with allergies from VOCs and construction dust. Aspen has made a huge difference in the quality of air in my house, it smells fresher and I can breathe better."
