HAMIIS Smart Air Purifier, Compatible with Alexa, 1560 sq. ft, Graphite

I have the 400S. The air purifier itself is great. Moves lots and lots of air on high. It's really quiet on low. Modern styling is awesome. The app is the opposite. It only halfway works. It appears like it will be an informative app for air quality and all that jazz. Well, you'll be sorely disappointed if you use android. Nothing works except some rudimentary controls. Maybe they will fix the app and all will be rainbows and unicorns. *update* The IOcare app has been updated several times since I posted my review. It works great. I think it's also worth mentioning that the S model features are only usable in the app. For instance you can't set a timer on the S model without the app. Not that this is a big deal to me, but I figured that some simple functions could still be set on the purifier itself without using the app...but that is not the case.

Not sure yet if rating is accurate, but first 24 hours going well. Purchased Tuesday and received Wednesday. Simple Setup with no assembly required. No noticeable sound on lower settings, and no smell some complained about. A little disappointed it is detecting no pollution, but when first turned on it did for about 5 minutes, and the air quality does seem improved over last 3 weeks since starting to run A/C constantly. I have to wonder about people complaining about a smell, especially burning plastic, if they stopped to read the flap on the box that says to remove the bags around the filters before operating.

This is the best household air filter I could ever imagine! It was easy to set up to Wi-Fi! I like that I can control the functions remotely from my iPhone. The user manual is very friendly to use. Maintenance is easy. Customer service is a phone call away! This is a well made product. The covers are easily removable to access the filters. There are indicator lights on the top that show the pre filter and the Max2 filter. These indicator lights let you know when maintenance is required. The cost may seem prohibitive — at first glance — but it’s worth the cost! Amazon allowed me to “pay it out” in a payment arrangement which suited me. The amount of dust the pre-filter captures is eye opening! I simply vacuum off the dust and replace the filter, the cover and hold the PreWash button to reset the filter indicator. The Max2 filter is supposed to last 12 months. The AIRMEGA is surprisingly quiet! I recommend this product to anyone that wants a whole house air filter that will exceed expectations.

Funciona perfecto! Se puede controlar con el app y tiene una funcionalidad Smart que automatiza todo el rollo. Excelente capacidad para cuartos grandes

After an enormous amount of research, decided on this unit for a large open space ~1000’sq. Looks good, and feels of high build quality. This purifier moves a lot of air on its Max setting, and you can feel the air movement from several feet away. It blows upward, so not a breeze like from a fan, but a gentle air movement circles the room. It’s also very quiet. In low you cannot hear anything, even standing beside the purifier. Medium adds a little white noise to the room. High is noticeable, but not a nuisance. Pros: “Smart” air purifier boasting a high CADR, attractive unit, solid build quality, decent price, and dual 12-month HEPA filters make this a smart investment. Dual handles make this easily manoeuvrable. Cons: Filter availability. The App: The app is decent, not great. It’s basically a remote control (on/off, fan speed) with a custom schedule builder if you don’t want the Auto mode enabled. Offers filter life indicators/notifications as well as indicators/notifications when to wash the pre-filter filters. Air Quality Index (AQI) is not available in North America. If the 400S (“S” = Smart) is a few bucks more than the 400 (standard) then go for it… but consider how much more you are willing to spend for the ability to control fan speed and receive notifications on your phone. Filters are not easy to find, perhaps due to the popularity of HEPA in the age of COVID, …but like face masks, hand sanitizer, and toilet paper… I’d expect that to normalize soon. All said, we’re happy. Would not hesitate to purchase again.
