Fresh Scented Air Filters - for HVAC equipment

Random though (surprise): I know there are a limited number of companies that sell and I believe one or two that make scented air filters for HVAC equipment. But after a thorough duct cleaning, this thought came to fruition (or "fluition" for some folks) for a colleague. After some thought on this thought, here are some of my useless thoughts, although some nerdy business folks may enjoy this as much as I did writing this post.

I believe the key to this project is marketing and a price point that is equal to normal filters.

Concept Summary:

• Use commonly manufactured paper and fiber HVAC filters (must get to the manufacture purchasing level for competitive leverage).
• Use a non-petroleum base fragrance and apply to the filter.
• Use this scented filter as normal in any equipment

Sounds simple... but why would anyone buy such a thing?
POINT #1
How about this statistic:

Candles cause an estimated 15,600 fires in residential structures, 150 deaths, 1,270 injuries, and $539 million in estimated direct property damage each year. 

(USFA Candle Fire Safety)

Many people use candles for room aroma while take a large risk of property damage or worse. 

POINT #2
Most HVAC filters are not changed on a regular basis  which causes inefficient operation (using more electricity), premature malfunction, and the circulation of dirt and other floating debris. The scented filter would provide comparable filtration; however, when the fragrance is diluted and ineffective (2-4 months), this will act as a reminder to change the filter (for a true benefit in efficient HVAC operation).

Benefits Summary:

1. Safer way to add an aroma to your home or office
2. Acts as a reminder to change filters for efficient operating and longer lasting  equipment

Ok, I'm done. Your Turn - what's your thoughts?
