Replacement Filters & Cartridges
Keep your system performing

How to Choose: Filters & Cartridges Buyer's Guide
Match by micron and media
Replacements are rated by micron size and media type (sediment, carbon block, KDF, RO membrane). Match the spec to your system, not just the brand.
Don't stretch the schedule
An expired carbon filter can dump trapped contaminants back into your water. Follow the gallon or month rating — whichever comes first.
OEM vs. compatible
Third-party 'compatible' cartridges can save money but vary in quality. For RO membranes and lead-rated elements, we lean toward OEM or third-party-certified replacements.
