The Unicel FG-1248 Pentair Purex Replacement Filter Grid is compatible with the following DE filters: the Purex/Pentair SMBW2000 series, the SMBW2048 Purex/Pentair SMBW4000 series, and the SMBW4048.

DE (diatomaceous earth) filters are ideal for the cleanest, most sparkling pool and spa waters because they can trap debris as small as 2-5 microns (for perspective, a human hair measures between 30 and 120 microns). That’s why many in the industry call them “water polishers.”

DE filter grids can be cleaned and recoated with DE powder to lengthen their life, but at some point, they become too worn or damaged to be effective; expect a lifespan of 2-3 years. This Unicel replacement, made of spunbonded, 100 percent polyester material, will require cleaning less often than other filter grids, and it will last longer, too.

Freight Shipping Information (LTL)

Some items are too large to be shipped with a regional carrier, FedEx, or USPS, and we ship these items with our freight carriers.

Please read the information below so you fully understand the delivery process and requirements.

Required Actions

We will need your phone number for the delivery. The carrier will need to call you in order to set up a delivery time. Please make sure the number you provide during checkout is the best one to reach you. If paying with PayPal, please make sure the number on your account is accurate.

You'll need to inspect your package upon arrival before you sign. If your order arrives damaged, you should sign "DAMAGED" on the delivery receipt. If the item is damaged to the point that it is not usable, you can refuse the item.

Please notify and, if possible, send photos of any damage to vminnovations_help@email.spreetail.com, along with your order number. A member of our Customer Experience team will reach out to you with further instructions.
