I have been using IDM's Control-A-Flow product for several years. I have just recently tried their Comfort First Filtered Diffuser which I feel is the best way to go. This product does exactly what it is designed to do and everyone who I have installed this in their office just love's it.

When you have an 8' ceiling in an office environment,,standard diffusers can be the cause of most temperature complaints. Your diffusers eliminate skin effect cooling and force the air across the ceiling instead of a downward angle. Also in a clinical area the extra filtration is helpful.

The product was defect free and had a very nice finish. All parts fit and the installation was easy.

The product was installed in our superintendent of school's office and he did not find the low profile product objectionable. I will be installing many more in our administration building.

I worked with David Northcutt on ordering our product. He explained everything in detail, was very knowledgeable, helpful and stayed in contact with me.

The system works extremely well. We are in a factory environment and the exhaust fumes would come into the office. With this product, it provided clean air and the headaches we were incurring from before
