Frequently Asked Questions about the Ultra Water Filter
Can I drink well water or non-potable source water with Ultra?
Yes, you can.
How do I know if my faucet will be compatible?
Our filter is compatible with standard threaded faucets. Please check if your faucet model is compatible before purchasing.
The thread of our filter is F22, the most common size. If your faucet has a different size, please fill out the following questionnaire to identify which adapter is compatible with your faucet and we will send you a new one free of charge.
My faucet has a standard thread, but how do I know if I will need an adapter?
To identify if you need an adapter, it is important to fill out the following questionnaire.
Why do I have to change it every 3 months even if I use it infrequently?
The refill is made of carbon, a material of organic origin that can be a breeding ground for microorganisms, which over time can lead to bacterial growth. These bacteria accumulate behind the filter and can contaminate the water.
This is a normal situation with activated carbon filters, regardless of the number of people in the house or whether the filter has not been used for a while.
