What Clean Liquid Systems does
Clean Liquid Systems, now operating as Filters-ALF, is a privately held industrial filtration supplier headquartered in Spring, Texas. The company sells air, liquid, odor and fume filtration products to commercial and industrial B2B customers, with a stated product portfolio spanning eight core categories: liquid filters (synthetic media cartridges, sanitary food/beverage/lab fluid filters), air filtration/HVAC (HEPA, V cells, pleated, pocket, high-temperature filters), metal washable filters (electrostatic, kitchen grease baffle, screen mesh), bulk filter media rolls and cut pads (HOGTEX natural fiber media, fiberglass), odor and fume control (activated carbon V cells, bonded carbon blocks, reverse pulse cartridges, refillable canisters), rotating equipment and reverse pulse dust collector cartridges, paint booth filtration, and industrial filter housings. Custom industrial filters built to customer equipment specifications are offered as an add-on capability, leveraging in-house fabrication facilities. The technology base centers on industrial filtration media and housings — synthetic media, activated carbon (liquid and vapor phase), HEPA, electrostatic metal media, and natural-fiber HOGTEX — with proprietary sub-brands HOGTEX and ES Series. Sub-brands and specification breadth across air, water, fluids and fume domains are emphasized, supported by replacement filter compatibility with major industry brands.
The company operates a sales-led B2B go-to-market through three channels: a Request-for-Quote direct sales process for enterprise and custom orders, an own-storefront e-commerce platform for standard catalog products aimed at mid-market buyers, and a ThomasNet marketplace listing for industrial procurement discovery. Pricing is not publicly disclosed and is quote-based, with a downloadable product catalog (FILTERS-ALF-Catalog-2026-R1.pdf) as the primary discovery vehicle. Customer segmentation is vertical-oriented and includes commercial and public buildings, data centers, food and beverage, energy and power systems (oil, gas, power generation), specialized and sterile environments, and broad industrial manufacturing. The company is led by founder Don Palermo; no broader management team, investors, ownership disclosures, certifications, patents, or partnerships are reported in available materials. The firm recently rebranded from Clean Liquid Systems to Filters-ALF and currently has 11–50 employees. Revenue, funding history, and ownership structure are not disclosed.

Clean Liquid Systems competitors and assessment
Company assessmentDirect peers
- Koch Filter: Manufacturer of commercial and industrial air filtration products including HEPA, V-cells, pocket filters, and pleated filters. Closely comparable to Filters-ALF's air filtration/HVAC line and serves similar B2B customers in commercial buildings and industrial facilities.
- AAF Flanders (American Air Filter): Direct competitor in commercial and industrial air filtration, offering HEPA, V-cells, pocket filters, and pleated filters for HVAC and industrial applications. Vastly larger but with overlapping product categories that directly compete with Filters-ALF's air filtration line.
- HYDAC: Manufacturer of industrial filtration, fluid handling, and process filtration products including cartridge filters and housings. Comparable to Filters-ALF's industrial filter housings and liquid filtration products serving oil, gas, and power generation.
- Camfil: Global manufacturer of air filters and clean air solutions, including HEPA, molecular, and industrial filtration. Directly competes with Filters-ALF in HVAC and specialty air filtration, particularly for data center and cleanroom applications.
- Filtration Group: Privately held global filtration company offering air, liquid, and industrial filtration products. Comparable as a multi-category filtration specialist competing with Filters-ALF across substantially the same product portfolio.
Broad incumbents
- 3M: Diversified industrial conglomerate with a broad filtration portfolio including air, liquid, and HVAC filtration products. Comparable as a broad incumbent whose standard filters and replacement SKUs compete with Filters-ALF's catalog offerings.
- Donaldson Company: Large, publicly traded global manufacturer of industrial filtration systems across air, liquid, and dust collection. Highly comparable given Filters-ALF's industrial air filtration, dust collector cartridge, and rotating equipment focus, though Donaldson operates at vastly greater scale and breadth.
- Parker Hannifin: Diversified industrial manufacturer with a large filtration division spanning hydraulic, fuel, and process filtration. Comparable as a broad incumbent in industrial filters, including liquid filtration for oil, gas, and power generation that overlaps with Filters-ALF's energy segment.
- MANN+HUMMEL: Global filtration leader with products in air, liquid, and industrial filtration. Comparable as a broad incumbent competing in the same HVAC, industrial, and OEM replacement filter categories as Filters-ALF.
Emerging players
- Purafil: Specialty manufacturer of air filtration and odor control systems using activated carbon and specialty media. Directly comparable to Filters-ALF's odor and fume control product line for industrial and commercial applications.
