Title: So far so good!
Review: I have owned this product for less than 24 hours as of this writing. More updates as I have more to say/remember to do them. Also, I will be very verbose, the sort of in-depth information I want when I am researching products over $99 for purchase, so you really know what's going on. Hopefully it helps, but it may be TL;DR for some.My background: I am not a smoker and never have been. I was raised by a chain smoker and have spent the majority of my life around second hand smoke from parents, family and friends. I have stress induced asthma and have also been through experimental chemotherapy that has apparently permanently damaged my lungs. Over time, my lungs are slowly degrading, and as they do I become more and more sensitive to more and more things, which trigger my lungs to get irritated and produce phlegm to coat my lungs and prevent the irritation, which causes me to cough more and more over time. (It has been a lot of fun having this sort of lung disorder during the pandemic, let me tell you.)"Well, why don't you see a doctor then?" you may reasonably ask. My experience with doctors in the past has consisted of watching both my mother and grandmother die with (no joke) 30+ prescriptions each all at once (with 3 to 5 doctors all prescribing simultaneously and admitting to me in private that A) they were not consulting with one another, and B) nobody on earth could possibly keep track of the side effects of so many prescriptions at once), and my uncle wasn't far off that number when he died. I also have repeated personal experience with the medical industry that strongly supports my experience and belief that going to the doctor is going to be a financially insane choice (whether or not I have insurance) that I get little to nothing out of regardless. So I choose to avoid doctors and the medical/drug big business establishment like the plague whenever possible.When I realized recently that my lungs were noticeably irritated all the time when I was in my own home, but I was fine if I went outside, I decided it was time to step up my game. Enter this unit, which I researched before buying.My unit is brand new, not a returned unit. Upon turning it on, it told me that my air in all areas of the house tested was as good as it gets, with a reading of 001. This did not please me, because I know it's nowhere near that good. So I did an update of the firmware to see if that would fix the issue, and it did. The new display read 005, which was significantly lower than I expected, but the unit reduced that to 3, then 2, then 1 relatively quickly.Within about 15 minutes, the air in my (door closed) office started to smell noticeably different. Lighter, cleaner, fresher, more neutral. I was surprised. I also noted that over the next few hours, my coughing decreased significantly as long as I stayed in my office.When bed time came, I put the unit in my bedroom and turned it on full blast with the doors closed while I went to the kitchen to have a snack. At first, the bedroom registered 5. The unit quickly brought it down to 1. I noted that my coughing increased when I was in parts of the house that had not had the benefit of this device to clean the air.Returning to my bedroom after my snack, I noted that once again, there was a nice difference in how the air smelled in my bedroom compared to my kitchen.Normally it takes me a while to stop coughing enough to fall asleep when I got to bed each night, but last night while there was still coughing before sleep, it was markedly less, which my girlfriend commented on today. This morning, I woke up to the pleasant realization that my lungs did not feel irritated for the first time in a long time. I hadn't even realized how irritated my lungs were when I would usually awaken until it was gone.Moved the unit into my home office again, and turned it back on. It started at 5, and again rapidly cleaned the air until it was at 1. Then I began doing more experiments. I noted that when the AC kicks on, it goes from 1 to 2 or 3. When it turns off, the unit returns it to 1. When I open the door to my office, it goes to 2, and then back to 1 when I close it. When my cat walks into my office, it goes from 1 to 2 if I close the door after him, and stays there for as long as he is moving around. If I pet him, it goes to 3.Thinking this level of sensitivity was too good to be true, I decided to try further experiments. I closed my office door again, waited until it settled down, and sprayed some air freshener in my office. No change - it evaporated. Just as expected. Then I went down the hall and into my living room and lit a stick of natural compressed sandalwood powder incense. I returned to my office and closed the door. Within 2 minutes, this unit detected the incense in the air, rising to a 4-5-6 and then back to 3 when the AC turned off. The next AC cycle, it jumped into the teens, and then into the 20's, 30's, 40's as the smoke got going during the next cycle. When the count hit 45, it turned the ring green and stepped the fan up a notch.I found that I could watch the numbers go up when the AC was on, and down when it was off. It got up to around 86 at one point, and the ring sometime before that turned orange and stepped the speed up another notch. Now that the incense has burned out, it's dropping, with highs in the 50's, and lows i the 20's and cycling lower each time the AC kicks on again. It's been interesting to see it power up and down to match the particulates in the air.Build quality seems good, but the bottom can come off easier than I'd like. A couple times now I have tried to lift it only to find that it had un-screwed and the bottom and filter were not lifted with the rest of the unit. Easily fixed in a second or less, but if the bottom had a bit of "click into place", this would not happen when moving the unit.It is so quiet in sleep mode that last night when we went to bed, after I had it running on high for a few minutes while we had our snack before bed, that even three feet from it, my girlfriend could not tell if it was running and asked. This was with the AC not active. That's pretty darned quiet. It also was no issue for me to handle, and I am extremely sensitive to sound when I am trying to sleep.The top two levels of fan speed are relatively loud, with the highest speed being louder than my AC when it's kicked in. It is, however, the most smooth and beautiful white noise I have ever encountered, and I am an audio engineer.So far my experience with this is almost entirely good. Here;s what I don't like.1. The bottom unscrews too easily. No big deal, but irksome.2. The sensor didn't work when I got it until I updated the firmware, which forced me to download the app, sign up, and then give the app location permissions and blue tooth permissions. I also naturally had to sign it into my wifi network. I didn't want to use the app, or give the app these permissions. The app, however, will not run without them. Ostensibly, it uses location data to give you a report on local 2.5um particulate levels in your area (which it does), but I don't know what else it is being used for, and I don't much like having my location tracked by Google and every other company on earth these days.So far so good. It appears that particulates in my house are probably not as much of an issue as what those particulates are made of, and that I need to be more focused on reducing VOCs in the air in my house. But so far this unit has helped me breathe significantly better, and I'm very happy with how well it works.

Title: I mean it works
Review: So I don’t know what I expected but I am someHow underwhelmed. For the price of the unit I expected something more. What did I expect ? I have no clue at all, but it works so it gets 5 stars.It is efficient I will say that. The air particle counter detects everything. We have a two story house and you can even tell when someone takes a hot shower upstairs cause it detects the particles traveling down. If set to auto it never goes above speed 2 it’s so efficient. It gets loud above speed 2 and max speed does impair your ability to hear things like the TV not huge deal.The app I don’t use all that much cause I just set it to auto and let it run. From what little I’ve explored it’s simple and easy to use.It a beast in size though. This is not a small unit it is massive. It’s difficult to find an effective place to put it, and don’t think you can do the out of sight out of mind trick with it …. It’s tooooo big.Despite its size it’s incredibly light. One person can lift it, change the filter, and clean it.The led light screen is super bright and effective at displaying all the info you need.Now the filters, they work yes. This will be apparent the first time you open the unit to clean the filter off. It is amazing that that was in our air. But do not expect the carbon to do much as far as smells. It never got rid of smells for us . So that’s kind of a small disappointment. Overall it’s not the most expensive air purifier, it’s not the most extravagant, but it will do. Still think the price points is a bit big for this unit.

Title: Delivered what it promised
Review: Got this air purifier to alleviate whatever causes my wife to sneeze frequently. This device seems to do the trick. Never knew just how quickly cooking or leaving screen doors open on high pollen days affected the interior Air quality of our home.I like that it’s programmable to sniff out bad Air. When it does, it goes into action when certain air quality levels I set are exceeded then the device automatically reduced to the quietest mode when air quality level I set is met. But the unit works straight out of the Box without an y user programming and is very intuitive and easy to operate.The quietest setting is so quiet I had to confirm it was running when I first got it. the highest seeing gets pretty loud. Difficult to hear the TV over it.The display is bright and easy to read, but I also like the sleep setting which turns the display off.You can also set it to be controlled only by your phone. Our grandchildren love to push buttons, so this feature comes in handy when they’re around.The unit looks very nice. It’s fairly easy to move from room to room with build in handle slots and it’s light weight.Very happy I made this purchase so far.

Review: One of my best purchases in the last year!I live in a very small apartment. Eventually, my neighbor prepares some barbecues and the smell comes up and invades my unit... Before having this air purifier, I would close the windows to avoid the smell. Now, I can keep my windows open! I just increase the speed of the fan, and bye bye smell! Amazing!Super easy to clean, noisy may bother a bit if maxim speed, otherwise it's super quiet. Sleeping mode is almost "on mute"! 🙂

Review: Es la segunda vez que lo compro (le regale el otro a mi hermano, que despues de 1 año seguia funcionando al 100, se lo di para eliminar el olor del gato en su cuarto), tiene varias velocidades cada una un poco más ruidosa que la otra, pero sin llegar a ser molesto. El modo dormir no hace nada de ruido, incluso apaga la luz del display para que descanses a oscuras. Se maneja perfectamente desde el celular o con comandos voz mediante alexa. Yo lo uso todas las noches, porque mis perros duermen en mi cuarto por las noches y es excelente para eliminar el olor a perro (son 2 shitzus, asi que tampoco son muy grandes, ni sueltan mucho pelo. Pero para ellos me funciona perfecto)

Review: I have been using it in a relatively smaller room that what the filter is capable of servicing. It works great and fairly quickly. The PM 2.5 meter is more sensitive than my air quality monitor and brings down the reading rather effectively.App and Alexa control work very smoothly.Fan is not very loud. Sleep timer with sleep mode works very well.The setup is light in weight and the lights on the controls can be turned off as well.Overall very happy with the purchase.
