Buying Guide
Want the cleanest water? Pure water can change your life!
I remember when I first used an IAPMO-certified filter. My water tasted so much better!
Here are steps to finding the best one.
-
Certification: IAPMO means the filter is tested and trusted. Look for the IAPMO mark for peace of mind. This shows they meet strict standards.
-
Contaminants Removed: Some filters focus on lead. Others tackle PFAS “forever chemicals”. Find a filter removing whatever worries you most. Check the product label for specifics!
-
Filter Life: How long does the filter last? Longer lasting filters save you money and hassle. Think about how much water you will filter in a month.
-
System Compatibility: Will it fit your pitcher or under-sink system? Make sure the filter is designed for your system. Some brands use proprietary designs, and some will fit all brands.
-
Ease of Use: Is it easy to install and replace? Look for user-friendly designs. Life’s too short for complicated filters.
-
Cost: Balance cost with performance. Cheaper isn’t always better. Consider the long-term cost of replacements.
-
TDS Meter: Getting a total dissolved solids (TDS) meter is a good move. Test your water before and after filtering. See how well the filter is working.
