Including filter system and high-performance Coliform Bacteria filter.
Coliform bacteria are a family of microorganisms commonly used to judge water sanitation. If testing shows coliform bacteria, it can indicate that untreated water is entering your system through a compromised well, a cross-connection, or a plumbing intrusion. Often there’s no change in taste or smell, so lab results are what tell the story. You may also see the phrase total coliforms on a laboratory report, which refers to the broader group of these organisms.
In Havana households, a common response to a positive total coliform test is to repeat sampling, locate and fix potential entry points, and add a whole-home layer of protection. Total coliforms aren’t the same as E. coli but can signal conditions favorable to other microbes. Because contamination can come and go, many Havana homeowners choose treatment at the point where water enters the house so every tap is protected consistently.
For addressing coliform bacteria in a whole-house setup, the most effective single filter is usually a UV disinfection system installed at the point of entry. UV systems use ultraviolet light to inactivate microorganisms as water flows through the chamber, treating the entire home without adding chemicals. This method directly targets bacteria rather than relying on taste-and-odor media, and when a unit is sized to match your home’s flow it can provide dependable protection at every faucet in Havana.
UV works best when water is relatively clear because heavy sediment can block the light, so many Havana homes pair a prefilter with UV. If you’re selecting one primary technology specifically for total coliforms, UV is typically the workhorse option. Mr. Pure Water can help size and install the UV unit for your plumbing and peak demand, and with routine lamp and sleeve maintenance it delivers consistent, whole-house protection against coliform bacteria.
