The unit works great! Air quality has definitely improved as I have mild allergies so my sneezing and tissue consumption is way down. We really like the fact that you can see that the unit is functioning depending on the color of the Air Quality Light. Another reason we purchased this unit is the we only need to replace the filter yearly. Will see if that holds to be true. Second reason is the unit is extremely quiet, Even when running the fan oh high it is not that loud. Over all the unit is very well designed and even has small wheels to easily move it around. Great job Alen!!
The 75i was easy to set up and is simple to operate Instructions are concise. The machine is quiet and unobtrusive. It is not large, fits nicely in the room, and has a nice appearance. We are very happy with this purchase.
I spent many hours researching air purifiers and am completely satisfied with this model. Noticed after a short time running that the house air felt cleaner and less stale. Would recommend for a medium size house. East setup.
Love the air purifier, took me months to figure out which brand I wanted to go with and I went with Alen. After cooking food I see the light change and know the air is actually being cleaned. I recommend getting this if you want cleaner air in your home or office.
Our air purifier was quickly delivered and was a very easy set-up. We've only been using it for a couple of weeks and so far, are pleased with its performance. It is very quiet - an extra bonus!
