Air purifier I got for my grandpa on Amazon works so well, and is easy to setup and use even for the non tech-savvy! Great for ppl sensitive to dust, pollen, pet hair, Filter is super easy to slide out and check / wash / change. Originally saw this exact same model running in my kids classrooms at school. I use a different brand at home that I chose for the aesthetic design and am very happy with them, but the filter takes an extra step to access versus just sliding it out (linked mine under similar) LTKHome LTKFindsUnder100
