Pre-filtration is important because it prevents costly system damage and extends equipment life. When you install the right pre filter, it means that your customer’s entire system stays protected from harmful contaminants. Although many contractors might see it as an optional component, a good pre filter can actually save thousands in repairs and maintenance down the road.

What Happens Without Proper Pre-filtering

The Flint water crisis shows what happens when pre filtering fails on a large scale. When the city switched to the Flint River as its water source in 2014, inadequate pre filtration let lead and bacteria slip through.

The result? Over a billion dollars in damages and countless health problems for residents. All because the right pre filter water filter systems weren’t in place.

The truth is that systems without proper pre filtration often develop problems that could have been easily prevented. It means that you’ll likely be making more warranty service calls than necessary, and it also damages your reputation over time.

How Pre-filters Protect Your Installations

A good pre filter water filter system creates a first line of defense by:

  • Catching large debris before it reaches expensive equipment
  • Reducing wear on pumps and control valves
  • Maintaining proper flow rates throughout the system
  • Preventing premature failure of downstream components

For contractors, this means fewer warranty calls, satisfied customers, and systems that perform as promised for years.

Pre-filtration Options You Can Trust

There are three pre filtering approaches that can work for most contractor applications:

  • Strainers are perfect for commercial and industrial applications where reliability is critical. Their simple, rugged design handles tough conditions while maintaining low pressure drop for optimal system performance. They’re easy to maintain, making facility managers happy, and provide cost-effective protection for high-value systems. Our selection of industrial strainers includes Y-strainers and basket designs that can withstand years of demanding use.
  • Bag Filters excel in high-volume applications with heavy particle loads. Their great dirt-holding capacity means longer service intervals between maintenance visits. They’re cost-effective for large commercial systems, easy to swap out during routine service, and excellent for initial system commissioning when debris levels are highest.
  • Cartridge Filters provide finer filtration when you need it most. A pre filter air filter combination or pool pre filter offers excellent protection with higher efficiency for smaller particles. Their compact design fits easily in mechanical rooms with limited space, making them ideal for protecting precision components in residential and light commercial work.

Benefits Your Customers Will Notice

Lower Operating Costs

Systems with proper pre filtration simply run more efficiently. Your customers will see the difference in lower energy bills because pumps and equipment don’t have to work as hard when they’re free from debris contamination.

Although the initial investment in quality pre filtering might seem like an extra expense, it pays for itself quickly. It means that your customers enjoy reduced operational costs throughout the system’s lifespan.

Extended Equipment Life

One of the most compelling selling points for pre filtration is how dramatically it extends equipment life. When you explain that pre filtering can double or triple the lifespan of expensive components, customers quickly understand the value proposition.

Pumps, valves, and specialized equipment that receive filtered water or air simply last longer. That can translate to significant savings over time. It also means fewer replacement projects and more satisfied customers.

Consistent System Performance

What is pre filter technology’s biggest day-to-day benefit? Consistent performance that keeps customers happy. Whether it’s a pool pre filter maintaining crystal clear water or an HVAC system running at peak efficiency, customers notice when things work as promised.

Pre filtering ensures that system performance doesn’t degrade over time due to contaminant buildup. It means fewer complaints and more referrals for your business.
