Pentek Filters

Shop Pentek water filters, replacement cartridges, filter housings, bag filters, specialty cartridges, and accessories by product type, size and model. Pentek cartridges are available across slim and Big Blue formats, including common 10-inch and 20-inch lengths. Start with the model number on your current cartridge or housing when available; otherwise identify the cartridge type, approximate length and diameter before choosing a replacement. Open the exact family or product page to confirm micron rating, media, dimensions, flow information, housing compatibility and any product-specific performance or certification claims before ordering. If you are replacing an American Plumber, Everpure, or OmniFilter check the exact model number and product-specific compatibility information before selecting a replacement.

Find Your Pentek Filter

1. Identify the exact model or part number on the existing cartridge or housing whenever possible.
2. Confirm the format: slim cartridges are narrower than Big Blue / heavy-duty cartridges. Do not select by length alone.
3. Confirm the length or housing family: common Pentek formats include 10-inch and 20-inch slim and 10-inch Big Blue sediment filters and 20-inch Big Blue sediment filters.
4. Choose the correct filter type: sediment, carbon, specialty media or another verified cartridge family.
5. Open the exact product page and verify dimensions, micron rating, media, flow and compatibility before ordering.

Browse Pentek sediment filters or Pentek carbon filters, organized by cartridge size and format.

FAQs on Pentek Water Filters

What size Pentek water filter do I need?

Use the model number first when available, such as Pentek DGD-5005-20 / 155358-43. If the model is unknown, identify the cartridge length and diameter or housing family. A 10-inch slim cartridge and a 10-inch Big Blue cartridge are different formats and are not interchangeable based on length alone.

What is a Pentek Big Blue filter?

Big Blue is Pentek's heavy-duty housing/cartridge format. Pentair currently offers Big Blue housings in 10-inch and 20-inch lengths that accept large-diameter cartridges. Confirm the exact housing and cartridge model before ordering.

Are Pentek 10-inch and 20-inch filters interchangeable?

No. Length is a product-defining dimension. Match the required length, diameter, media and exact model or housing compatibility.

How do I find a replacement for a Pentek model number?

Search or browse using the exact model or part number, then verify the size and product type on the destination page. Similar model names can represent different lengths or diameters.

Are Pentek replacement filters compatible with other brands?

Some exact Pentek models may have verified cross-reference relationships with other brands or legacy product lines. Treat compatibility as model-specific and verify the exact relationship before ordering.

Do all Pentek carbon filters reduce the same contaminants?

No. Carbon media, performance claims and certifications vary by cartridge. Use the exact product page and supporting documentation for contaminant-reduction and certification information.
