Airmega 300S App-Enabled Smart Air Purifier (Covers 1,256 sq. ft.), True HEPA Air Purifier with Smart Technology, Compatible with Amazon Alexa

From the beginning, this filter did a great job filtering out pet odors, concrete dust and other contaminants from my small 600sqft studio apartment. It's quiet in all but the most intense setting, and the automatic mode responds quickly and accurately to changing conditions (it doesn't like my cooking, as I tend to burn things from time to time). Since moving to the suburbs I have also used it in a garage to periodically purge that damp, mildewy smell. The Wifi function didn't work upon arrival, but that isn't a big deal - all control functions are easily accessible via the buttons on top. Tech support was responsive and helped me with this issue. Operating costs: Over the past 18 months, I have gone through 3 sets of Max filters, and I wash the prefilters perhaps every month or so on average. The replacement Max filters aren't cheap - even the third party ones run around $50 - but breathing clean air is well worth it. If you use the automatic mode and your environment isn't very polluted, you won't have to clean and replace filters nearly as often. The cost of electricity is very region dependent. One day last week, the air quality outside plummeted very suddenly due to the wildfires on the US west coast. AQI PM2.5 has gone beyond "unhealthy" and all the way to "hazardous". The smoke has blotted out the sun. That's when this filter really came into its own. It's been running at max speed more or less constantly without a hiccup. The "change Max filter" light has been on for much of that, but as I anxiously await a set of replacement filters it continues to clean the air efficiently (albeit with a little extra noise). My new home is 1,600sqft so I bring it into the bedroom at night, and then out in the living room during the day. Beyond keeping the air clean, having an air filter during an emergency like this enables you to run your A/C (which may bring in some air from outside), as well as vent some of the stale air (due to CO2 concentration) from your living space without fear of breathing in too much smoke. Given the rapidly evolving science on PM2.5 concentration and health, I wonder how many extra days of life expectancy this filter has added for me and my family. I fear that wildfire smoke is going to be an increasingly common occurrence, especially for those of us on the US west coast. You may not be able to fix the air outside, but at least with this filter you can sleep and relax in a clean air environment. Highly, highly recommended.

Surprisingly this air purifier is not as heavy as it seems. The design is very sleek and clean, like having a very fancy box in your home for aesthetic purposes. The plastic seems very sturdy and great quality. The removable panels for the filters hook in place by strong magnets so that's a great plus. The filters are the green pleated type that filters out 99.999% of bacterial, dust, and fungal spores. High quality filter usually means expensive replacements in the future. The cord is jacketed and high quality, matches with the whole design of the unit. The instructions were very thorough and simple to understand but when I tried to connect it using the app, it took some time to get it working through the wi-fi. The buttons on top are touch-sensitive, so high tech it makes me uncomfortable because I'm used to the usual "push-click" of a button. Guess I'm too old school for these hipster gizmos. You will need to use a different app since the one that was made for this will be deleted. To our surprise, the air quality in our home was already rated good (highest rating), and thought that we just wasted money for a fancy air box that also works as a fancy night light with the lighted-up ring. The ring color tells you how the air quality is in your room as my picture shows, it means it's near perfect, 100% clean oxygen. It wasn't until we started cooking and all of the unventilated smoke started filling up our room that the Airmega really shined. It started screaming bloody murder and the ring changed to red, it cranked up the fans at the highest speed and got a bit loud but not loud enough where you need to scream at each other to talk, like our range hood does. Within a few minutes, the we noticed how quickly it got rid of the smoke and the room air quality went back to normal. The Airmega really takes its job seriously and we can rest assure knowing that we have an overpowered box that cleans up our air. Not looking forward to buying new filter replacements though. The only thing it won't do is babysit our kid and feed him.

The app works fine, running it on both iOS and Android. The fan itself is good. When it's on low the noise level is negligible, if you run it at medium or high, yes it makes noise. On medium, if it's in the same room as you you'd want to turn it to low while watching a movie. For day to day activity medium speed produces a tolerable amount of noise. Smart mode does a good job, alternates between sleep and low for the most part unless it sense dirty air. Collects a lot of dust out of the air. It monitors both filters in percentages, so when you get to 0% maintenance is required. For the pre-filter that mean it needs a cleaning which is usually a good vacuuming or you can wash them off. For the main filters it would be a replacement. The air feels lighter and smells better after this has been running. The air the comes out is slightly cooled if anything. Has a side bonus of being the first device in the house to issue a warning of an unstable wifi connection... All in all, love it and will get another one for upstairs.

No hace ruido Se respira la diferencia Se puede controlar fácilmente desde la aplicación, aunque la aplicación no es la más rápida a comparación de las demás aplicaciones. La aplicación muestra gráficas y datos en tiempo real. Lo volvería a comprar

Quiet, large and thick filters. Does not show exact ppm, but indicates good, moderate, unhealthy and very unhealthy. Fairly big unit compared to competition. Well built. Des not use bluetooth., but i guess can be monitored remotely via internet. Got it on sale, but would not pay full price. PreFilter is at 96% current state and hepa filter at 100%. Carbon filter integrated with hepa filter. Easy access to filters. Granular carbon filter; more efficient. Intelligent fan speed control increases speed when there is more pollution. Wish I had it last week when polution was at a high level indoor.

L'appareil en lui même est très bien. Il fonctionne parfaitement, le mode automatique intelligent fonctionne bien aussi. L'appareil n'est pas laid et fait bien dans le décors de la pièce. Il est aussi très facilement transportable d'une pièce à l'autre, je le déplace de temps en temps de la pièce principale à la chambre ou au sous-sol. La qualité de fabrication semble bonne, même si c'est du plastique (donc à manipuler quand même avec précaution pour ne pas briser les petits clips de plastique qui permettent de faire tenir les panneaux de côté et du devant en place, le prefiltre etc...). Le bruit est raisonnable aussi, surtout sur le premier niveau c'est assez silencieux. Sur le 3eme niveau (max), c'est comme le bruit d'un bon ventilateur. Par contre le point négatif est que l'application n'est pas traduite en français, et surtout, surtout, les commande pour Google Home n'existent pas en français !!!!! J'ai écrit au service à la clientèle, qui m'ont gentillement répondu que les commandes étaient juste en anglais.... Ouais, super... Donc à moins de mettre son Google Home en anglais et de lui parler anglais (ahemmm), vous pouvez oublier l'intégration "Smart home".... C'est bête. Avoir sû, j'aurais sans doute pris le modèle sans "À" qui coûte moins cher, mais bon, tant pis... Peut être qu'un jour ils vont finir par traduite.....

I have been using this air purifier for a couple months now, it's very quiet, even on the highest setting I can barely hear it running, it has HEPA filters on both sides to intakes air on 2 sides, is nicer looking than many other other brands, the cord isn't your typical plastic rubber type, but a retro cloth looking cord which is a nice touch. The app seems a little spotty but the unit itself has been excellent. While more expensive than other brands this unit seems far better made, and overall I would highly recommend this unit if your looking for an air purifier.
