Works well with minimum upkeep

I purchased my air filter in 2020 during covid and have been using it year-round ever since. Works well without much noise but has developed an annoying, shrill pitch occasionally. It is easy to change filters which I vacuum out periodically to extend the life of the filters. Recently, I purchased 2 more, one for each bedroom, and use the pet filters to deal with dust and dander.
