We rece'd this product a couple of days ago and set it up and started using it immediately. Both my husband and I can tell the difference it is already making in our home. Static electricity is gone. The dry feeling in our home has improved immensely. We bought a humidity reading device and set up as well and our humidity levels in our home are staying spot on for a healthy home. The unit is working as it should and does not constantly run due to the fact we are able to set it at our desired settings. Our home is a little over 1200 square feet and even though it is rated for a 1000 sq ft it seems to be working all throughout our home. Great product would highly recommend to others.
