I have been a customer of FiltersFast for over a year now. They provide excellent service. My filters are delivered promptly on time, just as requested. Last year the company mistakenly sent out an email which didn't apply to my account. I called them and they stated it was sent in error. However, they immediately offered a free filter delivery for us and were so kind and courteous. We will continue to do business with them. Great company and product. We appreciate it.
