On mobile so won’t grab all the links, but I’ve done a lot of research into air purifiers and can echo what most people said

• Most air purifiers over 50$ are as good as the ones that sell for 150$+
• I personally buy Winix
• An air purifier can clean a room in 1-3 hours, but since I’m paranoid I keep mine running 24/7
• Don’t buy anything over 100$, it’s not worth it (if you want super clean rooms, buy one for each side of your house)
• Clean your air purifier (just wash the filter) every month or two (there’s a lot of dust it traps)
• Enjoy the investment, air purifiers are great!
