Review on Aviano Large Room Air Purifier with 7-Stage Filtration System (up to 700 sq ft.), Includes 2 Replacement Filter Sets by Allie Diaz

With the auto function, the directions are not so clear. Just turn it on and if you don't select a fan speed, it's in auto mode. Very compact considering there are 4 filters, pre-filter, UV lamp etc. Seems to be working very well. I'm skeptical about the air quality meter as it always reads red when first started and always seems to go through the same readings every time it's turned on, even after it's turned on and reads green (clean air). turned it off and on again and suddenly reads dirty air again. (Maybe a test mode, like when all your warning lights come on for a few seconds after you start your car?) The durability of the filter will show over time. A set of 4 filters is available here on Revain, linked in some other reviews, or just copy and paste the model number and search filters. I'm still trying to figure out where to buy a spare UV lamp to have on hand when it inevitably fails. I had one that cost about $600 and it's just as good if not better than the PetAir. Highly recommended as it has a HEPA filter and UV light that kills viruses and bacteria. (Although this is not a false claim of a Chinese-made fake. It's hard to tell these days, the instructions are very poorly translated and it's not clear how "Auto Mode” works. To use Auto Mode, shift However, you just turn on the fan speed and that's it, the auto function is activated I I always leave the UV light on and Anon (Ionizer) is again a bad translation Comes with the remote control 1 fan speed is quiet 2 speed is audible but not intrusive , and the third fan speed is about the same as the decibels of a 737 commercial cab and that's normal because it really moves air satisfied Highly recommended if they ever come back to stock Let's hope it's the real deal of UV and HEPA in this new one The COVID-19 pandemic could mean life or death for me as I already am due to severe lung and other medical problems e disabled. Works fine when I enter this. Cannot compete at around $162 when purchased in March 2020.
