Filbur Manufacturing

What Filbur Manufacturing does

Filbur Manufacturing is a privately held US manufacturer of replacement water filtration cartridges, with a product line focused on pool and spa applications. The company was founded in 1992 and is headquartered in Lake Oswego, Oregon, operating with a headcount in the 11–50 range.

The firm's product surface is a catalog of filter cartridges designed to fit common pool and spa systems — a mature, replacement-driven category where revenue is tied to installed base turnover, dealer/distributor pull-through, and SKU compatibility breadth. Public commercial information is sparse: the input data contains no disclosed product specifications, proprietary technology, certifications, patents, trademarks, partnerships, named customers, or distribution channel partners, and the firm does not expose an API or digital integration surface.

The business model is consistent with classic aftermarket cartridge manufacturing — producing and selling physical filter SKUs through wholesale/distribution and dealer channels into the pool and spa service ecosystem. No pricing model, revenue figures, or segment mix is disclosed. The single technical data point in the source material is a confirmed "no API" finding, which is consistent with a non-software, hardware-goods business.

Broad incumbents

• Pentair: Pentair is a global water treatment and pool equipment leader whose cartridge filters, pool pumps, and broader filtration systems compete with Filbur on both OEM and replacement aftermarket.
• Hayward Industries: Hayward is a major pool equipment OEM whose systems ship with branded filter cartridges that compete with Filbur at the OEM level and through aftermarket channels across all pool/spa categories.
• Culligan International: Culligan is a major residential water treatment brand with replacement filter cartridges and consumables, serving dealers and consumers in categories that partially overlap with Filbur's water filtration focus.
• 3M Purification: 3M's purification division produces industrial and consumer filtration cartridges at scale and competes for the same replacement-cartridge spend in industrial, food service, and residential channels that Filbur addresses.

Regional players

• Dolphy Australia (Filbur Australia): Dolphy distributes Filbur-branded pool and spa filter cartridges in Australia and the broader Asia-Pacific region and is therefore a regional peer with the same product line at a different geography.

Direct peers

• Pleatco: Pleatco designs and produces pleated filter cartridges specifically for pool, spa, and aquatic applications and competes head-to-head with Filbur in replacement cartridges to retailers and service technicians.
• Harmsco Filtration Products: Harmsco manufactures cartridge filters and replacement cartridges for pool/spa, industrial, and municipal water treatment — directly comparable to Filbur in product form, materials, and replacement-cartridge focus.
• Unicel Filter Group: Unicel manufactures replacement filter cartridges and grids for pools, spas, and hot tubs — directly overlapping with Filbur's core replacement cartridge business and serving the same dealer and service network channels.

Emerging players

• Waterco Group: Waterco manufactures cartridge filters and pool/spa filtration equipment, mostly distributed through regional and international channels, making it a peer in product form although its geographic base differs from Filbur's US footprint.
• Clear Choice Pool Products: Clear Choice and similar online pool filtration specialists sell aftermarket replacement cartridges to consumers and service pros, competing with Filbur's distribution partners at the retail/channel level.
