Commercial HVAC Air Purification 

HEPA Filter’s

Installing a high efficiency particulate air filter (HEPA) traps up to .01 Micron(10 nano-meters) and due to COVID-19’s of 0.125 Micron (125 nano-meters)installing a HEPA filter to your business should eliminate COVID-19 in theory according too NYTimes.


The Iwave Ionizer is another form of ample purification for air purification / virus removal. Using patented technology “needle-point bi-polar ionization” creates equal ammount of positive and negative ions breaking down contaminants, pollutants, virus’s, allergens, smoke, mold, and bacteria by removing hydrogen from the mollecule leaving you with clean air.


Ultra Violet Lights use high intensity radiation sanitizing UV-C light rays. The Ion rays disrupts bacteria, viruses, germs and other contaminants by destroying the nucleic acid of the molecule. We reccommend to install 36+ watt commercial grade bulbs to properly remove the contaminents for your business.

Air Pollutants & Common Contaminants

Installing a High Efficiency Particulate Air Filters (HEPA), UV-Light System, IWAVE- Ionizer  can help eliminate up to 99.9% of most pollutant’s, virus’s, bacteria, and other harmful contaminents.

You can be ahead of the curve by having one of our systems installed and keeping your business open. Our custom designed systems can help you reduce viral load and contaminant’s by up to 99.99%

Germs & Bacteria

High-Efficiency Particulate Air Filters (HEPA) remove not only particulate but also airborne microorganisms in indoor environments. The majority of the population spend there time indoors, where air pollution levels are just about the same as outdoors. Having a custom air purification added to your HVAC system can drastically reduce these contaminent and bacterial levels. Giving your business the proper air purification too give piece of mind to your customers and informing the city that you are in compliance with COVID-19 business requirements.

Gasses & Pollutants

Nitrogen Dioxide(NO2), Sulphur Dioxide(SO2), Carbon Monoxide(CO2), & Ozone is to name a few common gasses that are in our atmosphere.

    I'm the chief engineer of a half a million square foot building and Christian Brothers is doing the construction of a medical facility. While working with the pipe fitting foreman, Jasen, and the sheet metal foreman, Travis, I have … More noticed that the quality of work that they require from their crews is outstanding and they have a great attention to detail. I would recommend this company for any projects that demand quality work. They will be recommended for future construction projects in our building.
