Custom Filtration

Engineered Solutions for Unique Water Problems

Not all water issues fit a standard system. Commers designs custom filtration solutions for homes and businesses with unusual contaminants, high flow demands, mixed water sources, or complex treatment goals. Using detailed analysis and application-specific media, we build systems that address exactly what your water contains—and nothing it doesn’t.

Frequently Asked Questions

What makes a filtration system “custom”?

Custom systems are engineered using specific media types, tank sizes, flow rates, and treatment stages based on your actual water chemistry and usage, rather than a pre-packaged one-size-fits-all unit.

What types of problems require custom filtration?

High iron, sulfur, tannins, PFAS, industrial contaminants, extreme hardness, sediment, mixed municipal and well sources, and unusual taste or odor issues often require multi-stage custom solutions.

Can custom systems treat both whole-house and drinking water?

Yes. Many designs combine whole-home filtration with point-of-use reverse osmosis or specialty polishing filters for drinking and cooking water.

How is system size determined?

Sizing is based on peak flow rate, daily usage, contaminant concentration, contact time requirements, and pressure loss calculations to ensure consistent performance at every tap.

Are custom systems harder to maintain?

No. While the design is more specialized, systems are fully automated, metered, and programmed for efficient regeneration or backwashing, with routine service schedules similar to standard systems.

How long does a custom filtration system last?

With proper sizing, media selection, and periodic maintenance, custom systems are designed for long service life, stable performance, and future expandability as water conditions or household needs change.
