Exactly what I needed for my system

Great experience ordering the AP431 replacement cartridges. The filters arrived quickly and were well-packaged.

Good Product

The filter works fine and delivery was no problem. No complaints so far.

Recommended for on-demand forced hot water heat system

This was recommended for my on-demand forced hot water heat system and has worked extremely well. I needed to replace some valves previously because of corrosion. Since the Aqua-Pure installation I haven't had any further problems.
