The most advanced A/C drain line cleaner ever developed

iFLO PRO® A/C Severe Clog Relief is a 5X concentrated formula built to instantly clear severe clogs and prevent overflows. iFLoBiotic™ proprietary technology harnesses specially formulated enzymes that target the Zooglea bacteria responsible for organic buildup in condensate lines.

It's a key part of the iFLO "Start Clean — Stay Clean" approach: use it as a pre-treatment before installing iFLO devices to clear the line, or to knock out an existing clog in under an hour. The formula keeps working for up to 24 hours, breaking down buildup and preparing the line for long-term protection.

How to use

PRE-TREATMENT

Start Clean

Use before installing iFLO devices to ensure the drain line is clear and ready for long-term protection.

CLOG REMOVAL

Clear It Fast

Pour the recommended amount directly into the A/C drain line to instantly clear severe clogs — typically clears blockages in under an hour.

ONGOING ACTION

Keeps Working

The solution continues working for up to 24 hours, breaking down organic buildup and prepping the line for maintenance with other iFLO PRO products.

VERSATILE USE

Clear or Prevent
