How it works is pretty simple: customers sign up online, select the size of filters in the home, choose the quality of filters, how often they’ll be changed, and then filters arrive on your schedule – creating a physical reminder that it’s time to change them. There is no charge for shipping and the company offers three different filter grades that range from $10-20 per filter. I mean, if we are getting razors and meals delivered to our doorstep monthly, air filters should be a priority. By changing filters regularly, homeowners can expect to save over $100 a year (5-15% a mo.) on their heating and cooling expenses while avoiding multiple trips to the store searching for the correct size filter. So, if like me, you can’t remember when you changed your air filters and the service makes sense. What makes their business model even more interesting is their approach: the subscription-based model. It makes sense because it ends up attracting a broader customer base by offering offering a lower upfront cost to consumers. As a 2013 graduate of tech accelerator The Iron Yard, FilterEasy officially launched in the Spring of 2014 experiencing immediate month-over-month customer growth. The startup was founded by Tarkington and Kevin Barry who started the company while attending North Carolina State University. After a painful and time-consuming experience buying and changing air filters for their apartments, the two begun working on a service that would simplify the process of buying and changing the right air filters for the right dwelling. “The majority [of the funding] will be spent on marketing and additional team members to support our growth. We’re also working on tools to serve the small business and commercial space which are in development now,” explains Tarkington
