I like it a quite a lot, but wonder why it switches so quickly - within seconds sometimes - from red to blue. I’ve also been unable to get the app to work - it simply won’t pair.
The purifier itself is working well. I must say though that the advice as to what filter unit was appropriate vary depending upon who I spoke to. I believe there needs to be more consistent training over there to make sure that people tend towards the same correct solution
It’s too soon to evaluate my purchase. All the bells and whistles work as stated. I don’t have the equipment to measure the 75i’s efficacy, but my asthma should reveal how well it works.
I’ve had 2 of these for a week now and they are very impressive. Larger than I expected and very well built. I have one on the 1st floor that’s extremely quiet on it’s lowest speed and one upstairs in my bedroom that makes a slight ticking sound on the lowest speed that’s not enough to bother me and both run smoothly on higher speed’s. Air smells clean and overall I am very happy with the units. They also look great !
