Filter Availability

We pride ourselves in being able to locate that “hard to find” filter, and we have a large pool of major manufacturers that provide quality products equal to the OEM’s.  Plus we keep 1,000’s of filters in stock, from commonly used numbers to ones you likely won’t find anywhere else in town. At BIG 4 we are dedicated to helping you find the filter you need.

Customer Service

Offering superior filters is one thing but when it comes to customer service BIG 4 is the Oklahoma leader. In addition to a large inventory and product knowledge second to none, we offer a route pick-up and delivery service to keep your plant supplied. As a part of that service we can also keep your filter storeroom stocked at levels to meet your filtration needs.


In addition to offering new filters, BIG 4 can renew your filters for reuse at a fraction of the cost of new. Our proprietary multistage cleaning and quality inspection process restores your dirty filter to manufacturer’s specs, saving you 40% or more over the original cost. Many filters can be renewed over and over, saving you even more money while significantly lowering landfill waste.


Great service, extensive product availability, and reasonable prices give you the BIG 4 value. When you combine our renewal service with our discounted new filter pricing, your savings are multiplied. Plus every filter we supply carries a manufacturer warranty and our promise of 100% satisfaction.
