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?
I used a Winix one I got from Costco and it works well. One caution: air purifiers frequently include ozone generators which do technically clean the air, but ozone is super unhealthy to breathe in.
