I am convinced that you were right all along.
Just wanted to send you a note of appreciation for the Clean Air Effects electronic filter you installed last month. As you know, I suffer from COPD, which is the main reason you convinced me to upgrade to the electronic system. After just a few days, my quality of life had improved tenfold. Usually, when I wake up in the morning, I would always experience shortness of breath due to the high concentration of pollen in the air. You mentioned "Sick House Syndrome" in your sales pitch, but I brushed it off and didn't take it seriously. Now, however, I am convinced that you were right all along. With the new electronic filtration system in place, my breathing has been normal and I feel healthy and energetic once more. My wife Juanita says she feels better as well, so your exceptional filter must be doing something right!
