Maintenance Is Something I Never Ignore
I always think about upkeep before making a purchase. A washable or removable filter is important to me because it helps keep the air cleaner and the unit running well. I also check how easy it is to clean the front panel and drainage system. In my experience, regular maintenance extends the life of the unit.
