The BreatheSmart 75i has become a welcome member of the family in a short time. It fits in well, even in our small home. Usually the fan works on the lowest power level, and the sound is barely audible. Once it picks up impurities in the air (kitchen activity, animals or occasionally taking off your shoes too close...) the sensors are on it, filtering the impurities from the air. The color light indicators provide a great guide for air quality. We bought two units to be prepared for fire season, which has spared us so far. That said, we feel confident this was a good purchase.
Got this as CO wildfire season was starting. No sore throats with the smoke in the air so far. If our door/windows are open the indicator light changes quickly. We keep it on its highest setting and it’s very quiet. Would recommend.
Best investment ever, we now have 2 breathsmarts and 1 T500 and are very pleased with how it handles the air quality in our home. Highly recommend because of the design and how it fits perfectly and is so quiet.
I bought this for my air conditioned garage where I paint and my son plays music. It is bigger than needed but the garage isn’t perfectly sealed. It was easy to unpack and set up. The instructions are clear and uncomplicated. It was easy to register, since this is my fourth Alen machine and I knew to take a photo to get the serial number. It works perfectly. I love the air quality sensor. I check it when I go in to the garage and it’s always on blue (except for the time my son burned some incense and it was purple for an hour or two - fascinating and educational). I set it on automatic and keep it running, and also have a filter subscription.
