Top-Rated Air Scrubber Systems
We often recommend air balancing in Wilmington as a first step toward better IAQ. Even in newly constructed homes, the ductwork is rarely balanced. Through these techniques, we’ll ensure that static air pressure is right for your air handler. We’ll also make sure that nothing is obstructing the airflow.
If the ducts aren’t balanced, there are a number of solutions depending on the core issues. In some cases, you’ll just need professional cleaning. It may be necessary to reseal the ducts using the EPA-recommended aerosol method or re-insulate them. In rare cases, it may be that the duct network is simply too large or misconfigured for the house.
Mechanical ventilation is an option as well. Many newer homes simply don’t get enough fresh air through their passive ventilation systems. The solution to this is often a whole-house fan. It will add the fresh air you need but not the pollutants and contaminants you’re trying to avoid.
Once we’ve optimized your ducts, you can focus on how to use them to your advantage. One option is to install UV lights in your ducts. UV-C is a germicidal light that neutralizes pathogens. It also neutralizes contaminants like dust mite eggs and fungal and mold spores. Ducts are an ideal location for UV lamps because the air is relatively slow-moving. This results in longer exposure to the ultraviolet radiation.
An air scrubber is an option as well. One of the most popular products on the market was originally designed for the International Space Station. Manufacturers have since adapted it to residential use. It includes a UV lamp but also a process that charges molecules. Those charged molecules then neutralize pollutants in the air and on the surfaces throughout your home.
There are larger air scrubbers, too. These can house several filtration stages, including pre-filtration, absorptive filtration, and mechanical filtration. The pre-filter blocks the largest particulate matter to extend the lifespan of your more expensive filter media. The absorptive stage, which usually uses activated carbon, absorbs odors, chemicals, and gases, including volatile organic compounds.
The mechanical stage typically uses a high-efficiency particulate air filter (HEPA). A HEPA filter removes 99.97% of all particles down to 0.3 microns in size. You generally can’t install a HEPA filter on the supply side because it restricts airflow too much. It’s perfect for the return side, where this is much less of a concern.
You may be able to improve filtration on your supply side. HVAC filters have a minimum efficiency reporting value (MERV) rating. This indicates filtration efficiency and airflow restriction. Most modern systems support a filter with a MERV rating between 8 and 13. Despite that, the average household has a filter with a rating well below 8. Our team can help you choose the best HVAC filter for your home.
There are many health benefits to better IAQ.
