Antibacterial sealant on air lines removes bacterial contamination in the pipes and protects them from future contamination. There may be many types of contaminants in HVAC systems. Depending on the environment and conditions, these contaminants may promote the growth of mold/mildew (i.e. fungal growth) and other microorganisms. Other contaminants may include debris from outside air sources, fire residue, dust, pests, etc.
If done safely under the right conditions, the application of antibacterial sealants may remove residual contaminants invisible to the naked eye, such as mold spores. As the solution dries on the pipe, the barrier it leaves behind may also continue to kill bacteria in the pipe after initial use, helping to prevent regrowth.
Antibacterial sealants are recommended in the following situations:
- mold or mold growth
- pests nesting or insect pests
- A large amount of smoke slag accumulated on the pipe surface
- the pipe construction waste amounts of dust accumulation
1. What is an antibacterial plumbing system?
In contrast to topical antibacterial sealants, antibacterial piping system sealants are built in to prevent contamination. In this case, the duct material is bacterial-resistant and has an antibacterial coating.
Antibacterial plumbing systems have both advantages and disadvantages. One positive aspect is that the installation is safe and does not use formaldehyde. Ductwork also helps protect your entire HVAC system from mold growth, pest infestations, and other common air duct contaminants.
On the other hand, the upfront cost of such piping systems is usually much more expensive than other duct alternatives. Additional material costs and advantages increase the initial investment, and some antibacterial piping systems are more expensive to install than many other plumbing services.
While it provides more upfront protection, many homeowners may not want to replace their entire plumbing system either, especially if problems with contamination inside their pipes occur only occasionally.
2. How long can anti-bacterial duct coatings in HVAC systems be used?
The duration of any antibacterial duct coating depends on the sealant used and its application. Many sealer coatings last at least a few years if applied properly.
