Winix AM90 Wi-Fi PlasmaWave Technology, Compatible with Alexa Smart App Air Purifier 360 sq ft Room Capacity White

Seller product so the return process is dead slow. Better go in for other alternative air purifier.

Muy recomendable!!! Notas rapidísimo el cambio en el aire del ambiente o lugar donde lo pongas, no hace casi nada de ruido !!

This is the second Winix air cleaner I have purchased. Great working system especially as I raise birds in the home Keeps feather dust down

I purchased this Winix AM80 air purifier to replace a BlueAir 411 Auto. I was tired of always cleaning that annoying cloth filter on the BlueAir, plus taking that purifier apart to change the filters and reassembling is such a pain. Also, the BlueAir sensor sucks as it only a handful of times in four years ever increased the speed or showed a light other than blue. This Winix air purifier is SUCH a huge upgrade. The product is substantial and very well made. Installing the filters was a breeze and the buttons/app work great. Regarding the PlasmaWave feature, go to the Winix website as the Amazon page doesn’t describe this in detail. The charcoal filter can be washed plus only needs to be replaced once per year at the same time as the HEPA filter. The sensors on this Winix air purifier are very sensitive and are constantly ramping up the airflow and turning amber or red. I feel like this is the first air purifier I've bought that actually works! I did a side-by-side comparison of air movement with the BlueAir 311 Auto and the Winix AM80 is about twice as powerful....moves double the amount of air. On the lowest setting there is a slight hum from the unit but it's barely noticeable. Regarding the auto sleep function - the Amazon website doesn't describe this well. The purifier will go into sleep mode ONLY if it's set to Auto and the lights are turned off. If you have the purifier set to a higher speed (meaning not in Auto mode) it will NOT go into sleep mode if you turn the lights off. So for those looking for something that moves a lot of air or creates white noise to sleep, this is for you! Of note is the fact that the blue/amber/red light will not dim unless it's in sleep mode so if the light bothers you while trying to sleep, you'll likely need to turn the purifier away so it's not shining in your eyes. Lastly, before purchasing this I did research for a medical-grade air purifier. IQAir, NuWave and Austin Air were the ones I was considering. In reading online reviews, these products all work similarly, just the aforementioned ones are needlessly expensive (and ugly!). Getting a HEPA filter that can remove contaminants down to .003 microns is what is important and the Winix does this! Of note is the Amazon websites for the Winix products give misleading numbers regarding the actual microns...it states both .001 and .3. Look on the Winix website at either the product page or their filter replacement page for the AM80 and you'll see that the accurate number of the HEPA filter is .003 microns. Get this product, it's affordable, elegant, powerful, and actually works!

Soy asmatica y sufro de muchas alergias desde que lo tengo en casa me ha ayudado muchisimo. Casi no hace ruido.

LOVE this purifier. I bought it after using one we have at a machine shop. Super quiet, I don’t even know it’s on except for the light indicator. I like the different settings but I especially love the automated filtering. It will kick on higher automatically if it senses the air quality is bad to quickly purify the air. I love the indicator that tells you how bad the air is. At work we leave the room if the indicator turns red until it is safe to return after the machine is done purifying and turns blue again. It will also indicate when it is time for a replacement filter. I’m very happy with my purchase and would recommend it to anyone.
