Awesome tests! I look forward to you sharing your results and conclusions.
I agree it is exactly the same as furnace filters. They have a recommended time, but I’ve had some that end up having to be changed in one fifth of their recommended life cycle because of our shedding little cats causing extra clogging. The HVAC guy came to our house and said the filters were getting clogged up faster than expected and we have to change them more often. They didn’t last anywhere near what they were supposed to at that house. In other places the filters lasted way longer. So I’ve seen that it totally depends and their recommendation is just an average, and often recommended on the low end just so you’ll replace them more often or to ensure it’s always working best.
Your concerns are great ones. All I can say is, for my needs and based on decades of filtering experience, this unit kicks butt. My main concerns were filtering ability (pollen, dust, cats, cooking odors and cigar smoke) and noise. Both are the best that I’ve experienced. Even if your indoor AQI is poor (which I doubt based on your HVAC filter replacement diligence), one unit should drop your AQI well below the standard within a few days and keep it that way for at least 6 months for 1,000 ft². Of course, your mileage may vary depending on things like your house’s air leakage rate and outdoor AQI, cleanliness of HVAC ductwork, amount of open air kitchen oil frying, location/height of your unit, etc. Also need to take into account HVAC blower rate/cycling. I have my blower set to drop down to continuous 1/3 speed when AC/Heat is not active for constant air recirculation. As far as the unit’s filter-life-remaining calculation, for the main floor of 3 in my house, the calculation appears accurate. For the other 2 floors, it’s slightly pessimistic.
Yes, Wyze stated that the Air Purifier app is working at intended. So by them showing an advertising picture that is not how the app works, is nothing short of false advertising! One of the main reasons I bought this product was because it seems like a good feature to see an hourly graph of the AQI. But you’d think that Wzye would have at least taken down that picture showing the app doing something it doesn’t do.
Talk about arrogance, maybe they don’t understand that it’s illegal to advertise a product doing something it doesn’t do! And what is even more frustrating is that the graphing on the app doesn’t even work as Wyze had intended. Most days my graph has no dots, no matter what the AQI is on my machine. Other days it might have one or two dots at an AQI below 10.
I have 2 of them and they work the same way as yours. I also feel the same as you, I want to see a graph of what it was throughout the day not just when it reaches a predetermined bad level. Most days I have no dots, I think the most I have had is 3. Last I heard it should be working with the full graph of hourly reading on the 2.35 app release.
Yes, but you are missing my point. Wyze has falsely advertised this product from day one! I’m seriously thinking about contacting the FTC and filing a complaint if Wyze doesn’t take down that advertising picture showing hourly AQI dots on the app. It was never designed to do that and should not be advertised as such.
Oh and I’ve gotten AQI dots on the graph when the AQI was zero, so there is no redetermined bad level.
I look forward to you sharing your results and conclusions.
