They’re pricey, but my Air Doctor is the best damn air purifier I’ve ever had. We keep ours on low all day and you can hardly tell it’s on. When my kids had a combo of RSV, flu, and rhinovirus, I kept the air doctor in the room with them all day and never got sick. Same with when they got covid. I’m chronically ill and on immunosuppressants. I used to catch every virus they brought home, but since using the air doctor I’ve been spared from most of them. I also have severe chemical sensitivities (like anaphylactic to fragrances and VOCs) and the air doctor does a great job of filtering those out if someone stinky comes in our house.

We have the [Air Doctor 3500](https://a.co/d/0dVmhIw9) which works for large areas. It covers the whole first floor of our house. If you’re looking for something smaller for a bedroom, the Air Doctor 2000 is cheaper and covers up to like 300sq feet.

Our air doctor is amazing. They are expensive but definitely worth it. The only issue I have with them is the grates on the top of them. Our toddler pretty quickly figured out how to shove things in it and get them stuck in there and it can be a little bit of a hassle to get them out. They tell you how often to change the filter and they also have an auto mode, it runs low and quiet unless it senses something in the air or you can just turn it onto the lowest setting. It also has a lock so kids can’t change settings and a night mode so the lights turn off and don’t light up the room

[This](https://airdoctorpro.com/product/airdoctor-3500?variation=simple) is the one we have, the non-smart version. If you have a smaller space they do have smaller ones as well. They do all have the same features too.

AirDoctor 3500 has been amazing, I had Levoit and they don’t even come close.

We use an airdoctor in our living room/kitchen area + a big room dehumidifier that runs on auto. We also run a smaller airdoctor and dehumidifier in our master bedroom + bathroom. They’ve worked great for us in our house
