Fsi always has what I need in stock and they are quick to pull orders! The staff is always courteous and very helpful.

Great customer service-- especially the Office Manager Jen! Wouldnt go anywhere else for my filters. Great service and great prices.

I’ve personally met with the warehouse manager and she was a delight. Very articulate and organized. I’d also like to mention how clean and safe the warehouse appeared to be. She deserve’s a massive raise and free chicken wings on Fridays.

Wonderful place to get custom size filters. I wouldn’t go anywhere else for filters. Also a great place to work.

Great staff and welcoming atmosphere! Everyone does their best to make sure each customer has a great experience and leaves with the filter they need, including custom sizes that are made to order right on site!

Super efficient and always helpful. Jen at the counter and the rest of the gang up here make every experience as pleasant as possible.

Best filter pricing in Indy!! Wide selection of in stock filters! They can cut filters if your in a pinch, delivery service available for large orders at a very reasonable rate!

We have used Ernie for years as our filter vendor. I cannot think of another vendor who interacts with our organization at the level that Ernie does for us.If you have not given his firm a chance, you should.Sincerely,Roger Mooney

Awesome company with great people. I was recommended to use them because of their superior customer service, and they did not disappoint. I highly recommend them.

I always buy my filters here and they have exactly what I need and great prices!

Great service. Great people. Fun times.

This place is on point, and must have an amazing warehouse manager, because they always have what I need in stock, and always have friendly service to boot! A+

Great service every time!

Ive done business with Erine and the team at FSI Filtration for a few years now, its a class act organization. I would highly recommend them for service.

Lady up front very rude! Must not need the business.

Great staff!!!!!
