Primary Benefits
Feature
How It Works
Digestion of Solids
Live, beneficial microbes aggressively break down toilet paper, grease, and organic waste matter, converting them into easily managed liquids.
True Deodorizing
Eliminates foul sulfur and ammonia odors at the biological level instead of masking them behind short-lived chemical perfumes.
Easier Pump-Outs
By preventing solid waste from compacting at the bottom of holding tanks, it ensures a faster, cleaner, and more efficient pumping process.
System Maintenance Tip: Regular application of EM•1® helps replenish the beneficial microbial populations that are frequently wiped out by antibacterial soaps, harsh toilet bowl cleaners, and household bleach.
