Frequently Asked Questions

AI
Filters generally remove larger particles and chemicals like chlorine to improve taste. Purifiers typically use more intensive processes, such as reverse osmosis or UV light, to remove microscopic contaminants and pathogens.
Replacement intervals vary by brand and water quality. Pitcher filters often last two months, while under-sink or reverse osmosis membranes can last several months or even years, depending on the specific stage of filtration.
Many modern countertop systems now utilize reverse osmosis, making them nearly as effective as under-sink models. The primary difference is the installation process and the total volume of water they can process at once.
