Frequently Asked Questions
Everything you need to know about your water filtration solutions.
How do I know which replacement filter is compatible with my system?
You can find the correct replacement by matching the model number on your existing system or filter housing. If you are unsure, our search bar accepts part numbers, or you can contact our technical support team for verification.
What is the standard shipping timeframe for orders?
Most in-stock items ship within 1-2 business days. Standard ground shipping typically takes 3-7 business days depending on your location within the United States.
What is your return policy for unused products?
We offer a 30-day return policy for unused, unopened items in their original packaging. Please note that certain custom-built systems or used filter cartridges cannot be returned for hygiene and safety reasons.
Do you offer international shipping?
Yes, we ship to many countries worldwide. Shipping rates and duties are calculated at checkout based on the destination and total weight of the package.
