About Us

Rx4CleanAir sells replacement and OEM filters for industrial dust collectors, mist collectors and air cleaners. The store grew out of more than 50 years of hands-on work with dust collectors, air cleaners and complex filtration systems.

Most buyers know the part number on the filter they're replacing, not ours. So every product lists the OEM and competitor part numbers it replaces, and our Filter Cross Reference puts them all in one table. You can also start from your machine: each equipment page lists the filters that fit it, with size and media.

If you order the filter we list as the replacement for your OEM part number and it doesn't fit, we'll replace it or refund it and pay the return shipping. Not sure which part your unit takes? Send us the make and model and we'll confirm before you order.

In-stock orders placed by noon Central ship the same day. Returns are accepted for 30 days with no restocking fee.

Many filters have bulk pricing: the price per filter drops as your quantity goes up, and each product page shows its price breaks. For larger orders, purchase orders or tax-exempt purchases, request a quote and we'll reply with pricing.

Questions about a part, an order or a return? Use the chat on any page or email info@rx4cleanair.com. If you can't find the filter you need, send us the part number. We're adding products and may already have it in stock.
