Review: The iSpring whole house filter is extremely effective in filtering water, specifically well water in southern Alberta. Changing filters was simple and quick. Although it was helpful that the person that changed the filter was the one that installed the system. For my part, it was ordering the system and filters and communicating with Francis with iSpring. Francis provided exceptional service and gave me helpful and professional advice on more than one occasion. Much appreciated! Thank you again.
