AIRDOCTOR AD5500 New Model! 4-in-1 Air Purifier for Extra Large Spaces & Open Concepts with UltraHEPA, Carbon & VOC Filters - Removes particles 100x Smaller than HEPA Standard (AirDoctor 5500)

Does a Great job filtering out dust particles. Our home feels cleaner and looks better. The unit is extremely quiet, that was the most surprising part! Definitely recommend!

Very good unit. Runs quiet and efficient.

I very much wanted and needed this HEPA carbon filter to work. My wife has awful allergies year round. She is also very sensitive to odors or scents. I researched and researched through Amazon reviews as well as multiple industry reviews to select the best unit. And this unit was suppose to be one of the best. The Good: Its arrived well packaged and on time. The unit is attractive, light and very easy to roll around. The control board is easy to use. Love the auto setting feature, fan speed options and color lights to indicated when filters need to be replaced and how clean the air is. The auto feature is quiet once it purifies the air and the dim light feature is nice when running a night. The Bad: No review ever stated that this Air Dr unit process a scent even with the ionizer not actuated. It smells like a fabric softener smell which is what an ionizer unit would smell like. Turned on an ran on auto on the first night. Next morning my wife felt like she had Pneumonia. She looked and felt deathly ill. I double checked to ensure the ionizer was not on - it wasn't and tried running it for 4 straight days while my wife slept in another room. No effect. The unit process that same smell. HEPA filters should be odorless, this one is not! Bottom line: don't purchase if anyone in your home is sensitive to odors or scents. Thank goodness that unit was purchased on Amazon. They accepted my return free of charge with full refund since i owned it for less than 30 days. The remedy: i am going to bite the bullet ( a very expensive) and have a Abatement Air whole house HEPA filter installed on my HVAC unit, have installed UV-C lamps next to my HVAC evaporator coil and my air return, then finally install a Aprilaire 4" MERV 16 air filter. If i think of it, i will update the post to let you know how effective the remedy measures are to alleviate my wife's allergy issues, specifically pet dander, dust, mold and mildew, not to mention odors and scents. Hope this review helps the allergy suffers out there.

Set it and forget it

I purchased the largest size and it works GREAT! Cats' litter generates a LOT OF DUST and this unit handles it, no problem. I liked them so much I wound up purchasing 3 of them.
