Review on 📶 WiFi Enabled Blueair Classic 605 Air Purifier for Allergen and Hay Fever Reduction in Large Rooms up to 775 sq. ft. - ALEXA Compatible with HEPASilent Filtration by Panos Jordan

Problem #1: iPhone app won't connect: launches, cannot be configured manually; The phone connects to the device configuration - classic Wi-Fi, the application asks for my Wi-Fi password - freezes and returns to manual configuration. Many other reviewers have reported similar issues, for example the 680i can't connect reliably to systems that have both 2.5 and 5GHz. At first I thought not to bother connecting the app crash. The vacuum cleaner turns on and works. Problem #2: Terrible burning smell after a few days. I bought an older model with HEPA but no ESP recommended by Consumer Reports. CR recommends not using static electricity - the health hazard associated with ozone - but I grew up with an electrostatic air filter and thought I could live with it. But. terrible burning smell. Dust? dog fur? A Google search shows that many users suffer from the same smell. I feel it; not my wife; but her family has a poor sense of smell, for example, a brother cannot taste salt or hot sauces at all. The smell makes me sick, gives me a headache. Now I want to see if I can use the app on the phone to turn off the ES filter. but the app doesn't work. Now I wish I hadn't bought it. I wish I could heed Consumer Reports' recommendation against electrostatic filters. Apparently there is no way to turn them off. I did not return because a shortage in summer 2020 would have meant a delay of several months. I decided that having an electrostatic, burnt-smelling air filter was better than no filter at all. But I would not have bought it if I had known about this smell beforehand. Actually, "no filter at all" isn't quite right: I have three other room HEPA filters, both with activated carbon, and one electrostatic precipitator for the whole house. (I loaned some of these to family members who needed them during the 2020 wildfires). None of them have that burning smell problem. Blueair customer service is not responding at all. --- Almost a year later: The bad smell is still there, although it has decreased. This suggests that part of the odor may be related to an electrostatic filter and part to activated charcoal, the latter dissipating over time. Electrostatic air filter. === I would never have bought this unit if I had known about these problems beforehand and I would have returned it immediately if there hadn't been a shortage at the time. I strongly advise against buying this device. But. I will say one thing: its low speed setting is pretty quiet, much quieter than my other HEPA filters.
