We are a Baldwin and Fleetguard Filter distributor that purchases new filters directly from them.  We also purchase filters from stores going out of business or old inventory stores want to get rid of. If you wish to purchase any filters you don’t see listed in our store most likely I can order these filters for you. All Baldwin and Fleetguard filters are sold by the case unless smaller lots are shown. If you don’t need a full case message us and we may be able to sell lesser quantities.  We all want the best prices of anything we buy. If you see any new filters in the store that have a higher price than other stores you see in online, send me a message.

If there are any filters, we need to order, that does not have a message in bold above on supply issues you will be sent a personal text so leave a cell number as your contact.  If I have time, I will update you every week or two on progress or you can send me a text at 636-887-6799.

If you have a shop and those darn filters are just collecting dust. Send me a list of filters you have and how much you are asking and your location. I will look up part numbers you send to find the wholesale value and send an offer to you. The more presentable the filters are the more I can offer.
