Why You Might Need a WECO Whole House Water Filter
If your water supply is sourced from a well or local municipality that struggles with iron, manganese, or sulfur odors, you’re likely familiar with rust stains, a metallic taste, or a rotten egg smell. These contaminants not only affect your water’s taste and smell, but they can damage your plumbing and appliances over time. You might also be concerned about heavy metals like lead or copper, which pose health risks even at low levels. A whole house system like this filters water at the point it enters your home, ensuring cleaner water from every tap. This reduces maintenance on water-using appliances, improves shower experience, and can help protect your skin and hair from harsh chemicals.

Industrial Control Valve & Filtration Setup
Design & Build Quality
When it comes to build quality, the WECO KL-1665 stands out with its industrial-grade components. Many users praise the solid feel of the filter tank and the reliable control valve setup. The Katalox Light® media inside the tank is known for its efficiency in removing contaminants without frequent media replacement. One user shared that after installing it, they noticed a significant reduction in rusty water discoloration and unpleasant smells, stating:
"The system has worked flawlessly for months with minimal attention. The automatic backwash keeps everything clean without wasting water."
The system’s exterior tank is made from durable materials designed to withstand pressure and harsh water conditions. The control valve is engineered for precise operation, and includes diagnostics features to alert you if something is amiss—this is a thoughtful addition that helps avoid surprises down the line. The way the filter self-cleans with its backwashing cycle extends component life and maintains consistent water quality. The overall design makes it clear this filter is built to last and handle tough water problems.
Real-World Performance
In day-to-day use, the WECO whole house filter proves itself effective at eliminating common contaminants. For example, one homeowner with a deep well water supply noted their water had heavy iron staining and a sulfur odor that permeated through faucets and showers. After installing the KL-1665, the rust stains disappeared and the water smelled fresh and clean—making a huge difference in their daily experience.
The automatic backwash was a highlight for many customers. Unlike manual systems that require regular attention, this filter senses when it needs cleaning and performs the cycle by itself. This feature keeps water flowing smoothly without pressure drops and prevents media clogging. The controls for backwash timing and system diagnostics help you customize performance for your specific water conditions. It’s also well suited to serve as a pre-filter for reverse osmosis systems, improving those units’ efficiency by reducing heavy metal content upfront.

What Makes It Stand Out?
Compared to other whole house water filters, the WECO KL-1665 shines with its smart use of Katalox Light® media and an intelligent control valve. Products like the Aquasana Rhino or iSpring WGB32B also remove iron and heavy metals but may lack the advanced diagnostics and auxiliary relay features seen here. The programmable control valve technology in the WECO is industrial grade, granting you functionalities rarely found in home filtration.
This filter’s water-efficient backwash system is designed to use 80% less water than typical iron filters, balancing performance with conservation. Additionally, its capability to reduce a broad range of contaminants—iron, manganese, hydrogen sulfide, arsenic, copper, lead—makes it one of the most comprehensive single-media filters available.
While some competitors may have simpler installation or consumer-friendly user interfaces, those seeking reliability and heavy-duty filtration will appreciate WECO’s proven track record in both residential and industrial settings. Its suitability for reverse osmosis prefiltration is another plus that few whole house filters provide in such an integrated way.
Strengths vs. Trade-Offs
| ✅ Strengths | ❌ Trade-Offs |
|---|---|
| Removes iron, manganese, hydrogen sulfide efficiently | Complex installation may require professional help |
| Reduces lead, copper, arsenic, and turbidity | Control valve programming might be overwhelming initially |
| Automatic backwash system saves water | Larger footprint compared to smaller filters |
| Industrial-grade build and advanced diagnostics | Pricier than basic filtration options |
| Ideal for reverse osmosis prefiltration | Not a quick DIY setup |
Durable Build and Efficient Filtration
Who Is It For?
This whole house water filter is ideal if you are a homeowner struggling with high iron or sulfur levels that affect your water’s appearance, taste, or smell. If your water supply contains heavy metals like lead or copper, this system can add an extra layer of protection.
