Q：Why are my baghouse filters so expensive to replace?
A: Many simply buy their replacement filters from the OEM or sales rep that supplied their baghouse. Often times, manufacturers and sales rep organizations deliberately sell their units cheaper and then make convince their customers that they are locked into using a proprietary filter design that only they can supply and thus they charge outrageously high prices for them. Other times, they convince their customers to use an outdated or rarely-used technology so hard to find form other manufacturers that it nearly guarantees them your repeat business for replacement parts. This is common with many cartridge collector OEMs, whereby they win the initial unit sale by undercutting other manufacturers and then plan on making their profit on the expensive replacement filters later on. This marketing technique is commonly called the “razor blade” system, for its well-known use by makers of disposable razors and cartridges.
