The following article from the Journal of Occupational and Environmental Hygiene makes a compelling case for adding HEPA filtration to indoor environments in order to greatly reduce the chance of Covid spread.

The article has a couple of important points.

Based on their model, an office worker has a 40% chance of contracting Covid when sharing an office with an infected worker “Even with use of N95 masks in this scenario” after 1 week of exposure !

By combining HEPA filtration (12 Air Change per Hour – 12 ACH), the probability of contracting Covid from the office environment over a 6 month period drops to 0.003%.

Conclusion: Use HEPA filtration in indoor environments in this time of panemic, and continue to use to avoid other airborne pathogens.

CFB and Balanced Residential Make-up Air System

We have added videos on how to assemble our CFB and unboxing our Balanced Make-up Air System components. It is part of our ongoing goal to share new and interesting content and information to help you with your next project. What is a CFB? What is a Balanced Residential Make-up System? Lets break them down for you.

CFB Series MERV-13 Inline Filter Boxes

A CFB filter box is a high-performance solution for any application requiring in-line filtration. Constructed from 5052 H32 aluminum, the CFBs holds a standard 4″ filter and are designed to fit either 6″, 8″, 10″ or 12″ diameter duct. The lid attaches securely with latches, and opens easily for quick filter replacements. MERV-13 filters are included with every unit, but you can also upgrade to a MERV-15 filter. The higher the MERV rating the better the filtration and the cleaner the air will be in your home.

A balanced make-up air system is designed to “make up” the air in your interior space that has been removed due to process exhaust fans. This type of HVAC solution pulls in fresh, tempered air from outside your building to replace existing air that cannot be recirculated. The International Residential Code (IRC) requires that makeup air be provided for kitchen hood exhaust systems with a capacity of 400 cfm or greater. Our balanced make-up air system can be customized to fit your needs with silencers, electric heater for cold climates and wall/roof caps.

Both provide better air filtration for your home to keep the air clean of allergens, smoke odors and particulates in the air, as well as provide the in-home air circulation that you need. You can check out our videos by clicking the links below.

Over the past 2 years we’ve been building filtration products, so maybe it’s time to announce them…

The first unit we have is our IFB series. This “Inline Filter Box” has a MERV6 filter and is meant for general purpose filtration.  MERV6 is considered a “better residential” level of filtration. [Here’s a good overview of MERV levels]

HVACQuick IFB Series Inline Filter Boxes

This filter box is commonly used for filtering incoming fresh air to a furnace or air handling unit. If desired, we can provide inline fans all the way from 100 CFM past 1200 CFM.
