I was cleaning the other day and noticed some lint/dust getting sucked into the vacuum cleaner while I was holding it in the air. It made me think an air filter would probably catch dirt as it gets stirred up within the space.
Does anyone use one? Have you noticed a cleaner room/home as a result?
Got a Winix air purifier to help with the wildfire smoke we had a ways back.
I think it helped, kept it going since.
