New house only a year old and has not gone off of blue it’s in auto and appears to be working

My Sans air purifier is amazing! It is quiet, does an amazing job purifying our indoor air and that's with two pets and I quilt and sew at least five days per week which produces lots of lint. I am pleased with this purchase.

Super quiet but I know when something is in the air as it goes all in. Simply baking bread or other cooking smells trigger a higher mode, then it drops back to whisper quiet in no time.

I have the whole home model and very satisfied.

This thing is great. You place the filters, plug it in and it does the rest. Keep our air inside my home fresh and clean.
