Just wanted to say thank you so much for how well the ClenAir HVAC Odor Block worked for us. We recently bought a foreclosure home which was really beautiful, but the previous owner was a VERY heavy smoker and the nicotine smell in the home was almost unbearable. When we looked at the home, we almost did not make an offer on it because we did not think we could ever get rid of the smell.

We bought the home and on Wednesday at noon I placed a residential HVAC Odor Block in each of the AC return air vents. I ran the AC fan unit constantly over the next 3 days and when my wife walked into the home on Saturday noon, she was stunned. The cigarette smell was gone. We had several contractors work on the home over the next several days and they all said that they were shocked when I told them about the heavy smoke smell in the home because they could not detect anything.

To say the least, we could not have been MORE happy with the results of this product. It by far exceeded any expectations we had. It made our new house into a great home which we will enjoy for years to come. I told our realtors about your HVAC Odor Blocks so they can think about using it on future listings they may have which involve smelly homes. Thanks again for such a wonderful product.

Please accept this letter to confirm our unsolicited conversation, singing the praises of your HVAC Odor Block by ClenAir. I even used it in the corner of my office. This area gets installers and service people in and out all day. From hot, sweaty, body odor to food and smoke, ClenAir took care of the problem. Thanks again for a great product.
