Whole House Replacement Filters: Keep Your Water Clean, Fresh, and Healthy

What Are Whole House Replacement Filters?

Whole House water filters are the heart of APEC's Whole House water filter systems. These filters trap sediment, chlorine, iron, and other contaminants before water reaches your faucets.

Whether it’s a sediment filter for sand and rust, a carbon filter for chlorine and odors, or a specialty filter for iron or fluoride, using genuine APEC replacement filters keeps your water tasting great and your system running smoothly.

Tip: Even if your water looks clear, old filters can still harbor contaminants that affect taste and your system’s performance. Always use a TDS meter to test your water!

Why You Should Replace Your Whole House Filters Regularly

Over time, filters get clogged with dirt, chemicals, and other impurities. Regularly replacing filters ensures every sip, shower, and meal uses water that’s clean and refreshing.

Protect Your Plumbing and Appliances

A clogged filter forces your system to work harder, which can wear down pipes, tanks, and appliances. Regular replacement keeps everything running smoothly.

Keep Your Family Healthy

Fresh filters, depending on the filter's function, can remove harmful substances like chlorine, chloramine, and heavy metals, giving you peace of mind that your water is safe for drinking and cooking.
