Works wonders in my kitchen to get rid of funky smells after some cooking. Keeps the whole room smelling nice and fresh now. No more odors at all. Clean the air so fast.

If i add cat litter to the litter box in the bathroom down the hall and around the corner from where it is, the filter senses it and it's on red right away. Hay que esperar ahora cuando cambiarle los filtro ya que es recién comprado.

Great does as advertised. Sleep dimmer helps if you want the machine to be stealth at night.

The air doctor ad2000 4-in-1 air purifier awaits, ready to embark on a breath of fresh adventure. Smoking around the air doctor prompts it to a higher level of setting.

It works surprisingly fast and effectively. It really does work and auto adjust. These air purifiers help immensely!

Regular price is a complete ripoff. Overpriced when there's nothing terribly special about it. Impossible to purchase replaceable filter and send to different address for house sitter.
