Works too good 😂😭. I can’t even spray my lavender room spray without this thing kicking in and sucking it all away. It’s very quiet on all levels apart from it highest level. It’s lightweight. I dont know about its longevity yet.

This is wonderful. My son had one for over a year and highly recommended it. It’s comforting to know our air is cleaner!

Best air purifier on the market and totally worth the price. I live in a 1 br apt with 2 cats. If I cook food, it usually smells for several days. It now takes less than a day and you’d never know I cooked. I also find myself having to diet significantly less. It’s super nice to hear it kick on higher speed when there are more particles in the air. It’s pretty large but very quiet. Also love that you only have to replace the filter at 6 months. Most others I’ve tried have you replacing constantly.

Don’t let the 4 star confuse you, because I do LOVE my air doctor. Definitely not the cheapest, but it does amazing at improving the air quality in our home. We have a golden retriever as well for reference. This thing sits in our living room and kicks on anytime we are cooking. It clears the air relatively quickly, and I have even noticed how much better I feel downstairs vs how scratchy my throat is after being upstairs without it for over an hour. I am taking off a star because it is quite loud when it’s on the highest setting (which kicks on a lot after we prep breakfast on dinner.. as it should). I also purchased the blue air purifier for comparison and noticed that it is SO much quieter, however it does not clear the smells as quickly and is reported not to be able to distinguish particles as small as viruses like the air doctor. Highly recommend if you can get past the noise factor!

The AirDcotor 3500i I ordered came with a defective control panel (lights flashing on and off). AirDoctor customer service was prompt and very helpful in its response. They sent a replacement unit within a couple of days. New unit is great!

I rarely write negative reviews, even less than 5 star reviews as I’m pretty meticulous with purchases. Maybe I got a defective product & I am reasonably wary of negative reviews but the ones on this mirror my experience. Maybe you just like the idea of clean air & don’t actually have allergies but I am allergic to virtually anything you can inhale in the air other than oxygen, so I would know if a purifier actually works. I own 3 different Winix units which I’ve had for years and still work like brand new. After trying this AirDoctor unit out, I also no longer wonder why Costco carries Winix. There are actually purifiers out there this bad. Again, maybe it’s a defective unit but for something claiming to be even more effective than HEPA, I expected good quality control. I had the worst allergies I haven’t had in years when this thing was around. It seems to just spread dirty air around. I figured it might be the purifier causing the severe allergies when I disinfected a room with my UV lamp and it did absolutely nothing, even after hours of leaving it on max fan speed, to remove the typical post UV lamp smell in the air. I became highly suspicious of this after that, as my Winixes can remove that smell within minutes, and lo and behold, when I stopped using this purifier after that incident, my allergies resolved. The sensor on this never even turned any color other than blue, indicating clean air, when my Winixes turn red on obvious VOCs in the air. They go off even when I’m just using rubbing alcohol on my hands, even a few feet away. This? Absolutely nothing. No turning red. I don’t even know if it turns yellow. Never saw it. And I’m ironically glad it never increased speed on its own as that would have probably made me sicker. The noise level on this thing on max speed by the way is unbearably loud but looking back now was a minor inconvenience compared to the allergies I was getting. I highly advice that you do not toss even the outer box that this is packaged in, just in case, if you still would like to try it out for yourself. I did that as I just trusted that it would work after doing my research on this before buying it and it was a headache repacking it.

I am enjoying the air purifier. It works great. When I am cooking or dusting it detects the additional particulate matter within seconds and the indicator light goes to yellow or red and back to blue once the air is clear again. It is quiet in blue mode and only noticeable when it ramps up to yellow or red. I would recommend it, especially for allergy sufferers.

Works as described, did a bunch of research and ended up getting this for the office, the only improvement would be if the app allowed a weekly on off schedule allowing for change of fan speed, Would like to run this at night on 4/4 and during the day on Auto or 1/4 but as of now that's not an option without manual button pushing.

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.
