To whom it may concern:
I am writing this letter on behalf of Filter Engineering Corporation in Sterling Heights, Michigan. I have had a working relationship with the individuals from Filter Engineering for several years and have come to know them as knowledgeable and customer focused, the pricing is competitive, the delivery is timely and professional and their staff has extensive product knowledge and is responsive to customer needs and questions. I would recommend Filter Engineering to anyone looking for filtration products and installation services.
