History of Filter Renewal

It is a little known secret that most industrial air intake and dust collector filters can be renewed and reused multiple times, depending on the filter media and usage conditions.  When mildew resistant filter paper was first developed, many of the major filter manufacturers actually gave methods for cleaning their filters.  Although they don’t generally recommend it today, it is doubtful that any manufacturer would say that their filters are less able to hold up to the process than they were years ago.  See below and click the links for more information.


“Do-it-yourself cleaning techniques and improvised cleaning tools are risky and should be avoided. Commercially available air filter cleaning services are most likely better equipped and have more reliable techniques for cleaning air filters than most maintenance shops.”, from Filtration Bulletin SB_LT18727.

Donaldson® Company

“Most Donaldson elements are manufactured with washable filter media…The (cleaned) element retains the high efficiency of a new element.”, from a letter written to BIG 4 by the Donaldson Product Service Manager in 1987.

John Deere

“Clean Properly – Refer to Operator’s Manual” as shown on the end cap in this photograph of an older John Deere air filter. “Washing Primary Element” instructions are still shown in some manuals. See Section 140 of the Model 5103 Tractor Manual.

Filter Manufacturers Council

“Some vehicle owners and maintenance supervisors, concerned with lowering operating costs, clean and reuse their heavy duty air filter elements.”, as it is pointed out in Technical Service Bulletin 89-4R2. Note: The Filter Manufacturers Council is comprised of many of the major filter manufacturing companies.

Exclusive Process

We have developed a multi-stage cleaning and quality assurance process following the Filter Manufacturers Council guidelines, that cleans the entire filter element inside and out.  Our process is not done by an automated machine but by trained and experienced technicians who can tailor it according to the construction and contaminants of the filter element. At multiple points during this process, we perform different types of inspections. If the filter fails any of our tests we reject it at no cost to the customer.

98.99% dust removed

98.99% of all dust and debris removed, renedering a like new filter ready for reuse.
BIG 4 has been renewing filters for over 40 years. Our renewed elements carry the same warranty as a new element
FMC Guideline: “Use a commercial heavy duty air filter element washing (renewing) service whose operators are trained in proper washing techniques and inspection precautions…select a service that warrants the elements they wash”
We soak in mild detergent & back-wash as recommended, taking special care not to damage the media
FMC Guideline: “The most effective cleaning method is to soak the element in water, which contains a nonsudsing detergent…rinse the element from the “clean” side to the “dirty” side to dislodge the dirt”
We use air circulating convection ovens with computer monitored temperature controls
FMC Guideline: “Warm air must be circulated (to dry), with temperature less than 160 degrees F”
The lights in our visual inspection room will expose even the smallest of pin holes
FMC Guideline: “Inspection of the cleaned element is critically important. Inspect for holes and tears in the pleats by looking through the element toward a bright light”
We inspect all points of construction of an element, including gaskets and the total metal integrity
FMC Guideline:”Check for torn, loose, or partially-compressed gaskets, and dented metal parts.”
Our renewed elements are boxed for easy stacking and labeled with your internal part number then returned
FMC Guideline: “Filters that have passed final inspection should be placed in a sealed box and stored in a clean, dry place”
