3500i SMART Air Purifier for Living Rooms & Bedrooms. 3 Stage Filtration with Pre-Filter, UltraHEPA, Carbon/VOC. Captures Particles 100x Smaller Than HEPA Standard (AirDoctor 3500i Smart)

Works as advertised! It's a luxury expense, but it's obvious that it's pulling our particulates from the air. Not sure the smart features are worth the extra dollars, but I do like the control I have from my phone and getting updates when poor air quality is detected. Not looking forward to replacing filters in this unit due to the price. The unit is smaller than I expected it to be and much quieter than other air purifiers I've used with success. Would probably buy another one but without smart features.

So far I love these. They actually detect smoke in the air. Works great. Best air purifier I've ever owned.

Stopped working after 4 months. Seller did not offer a warranty. I called the head office and an investigation on the seller has commenced. The company only has an email address to reach out to them.

Definitely waste a lot of money on other air purifiers but this one I got my moneys worth had it for a year now it still works just like the day I bought it. I have the one with the app for my phone. Gives me the most updated information. The amount of hair and dust from pets that floats around in the air it grabs it all my house smells fresh and clean.

This unit is very good value. Got it on sale. Unit can sense any cooking odors within minutes. Have unit in bedroom and it turns to high setting almost instantly when cooking. My wife has breathing device for night and this really helps. When on low setting can hardy notice the sound
