Whole home air purifier installation service in the District of Columbia, Virginia, and Maryland regions.
When it comes to indoor air quality, every homeowner should be concerned. With the move toward more energy-efficient design, homes in Virginia, Maryland, and Washington, D.C. have been built tighter, meaning houses are sealed more effectively. This has inadvertently led to more contaminated indoor air.
The increased popularity of double glass windows, emphasis on insulation, and pervasiveness of weather-stripping has led to a decrease in indoor and outdoor air exchange. When fresh outdoor air can’t flow into the home, you save money on utility bills, but increase the likelihood of stagnant and polluted indoor air.
To counter the unintended side effects of energy-efficient home improvements, consider installing a whole house air purifier system to improve indoor air quality.
A whole house air purifier integrates into your existing HVAC system, taking the air that passed through your home’s ductwork and removing biological contaminants as air circulates through your central air system.

The air is drawn through your home’s intake vents and passes through one of four types of high-performance air purifying systems: flat, extended media, electronic and ultraviolet. Each method is used to improve indoor air quality and increase the comfort of your home.
Your HVAC system already contributes to whole house air filtration. As your system circulates heated or cooled air, it forces the air through a thin filter. This filter is the least expensive method and is an easy way to quickly improve your indoor air quality. Flat filters require frequent changing, typically on a monthly basis, or else you’ll run the risk of overworking your furnace or air conditioner. If they become too clogged with dust and dander, it can decrease your energy efficiency. Homeowners can easily install and maintain this filter on their own.
These filters are more sophisticated than flat filters, requiring professional installation. Extended media filters can trap smaller, harmful particles and are changed on an annual basis.
If you want to trap toxic particles, including secondhand smoke, then an electronic filter is a great fit for your home. The only requirement is a 120-volt electrical outlet and you’ll need to wash the aluminum collector plates every few months.
This type of air filter is designed to eliminate organic pollutants like mold, fungus, and bacteria. The UV light in the system kills germs and can specifically target small, biological contaminants. Hospitals usually install ultraviolet filters because they’re excellent at zapping up germs, viruses, and bacteria.
John C. Flood offers installation of an Air Knight UV whole house air purifier. This specific model leverages germicidal UV lights that work with filtration by reducing biological contaminants 24/7 — even when your HVAC system isn’t running!
The Air Knight air purifier uses patented technology including high intensity UV light, the humidity in your home, and a quint metallic catalyst to create vaporized hydrogen peroxide and millions of positively and negatively charged ions that are then distributed through your HVAC system into your home. The vaporized hydrogen peroxide attacks harmful pollutants in the air, eliminating bacteria, viruses, and mold spores on contact wherever they exist in your home, in the air, and on surfaces like your countertops and doorknobs.
This whole house air purifier system is installed on the supply side, immediately after the A-Coil or on the return side prior to the fan coil unit, so it doesn’t cause any disruption in your home.
Even if you’re constantly cleaning your home, there’s no amount of dusting, vacuuming, or washing that can eliminate air pollutants as effectively as a whole house air purification system. Homeowners in the Virginia, Maryland, and Washington, D.C. region have trusted John C. Flood to maintain pure indoor air quality for over a century.
If you choose to install a whole house air purification system, you’ll see a reduction in allergies and other respiratory health issues. We care about your family’s comfort, which is why we’re currently offering $100 off an Air Knight UV Air Purifier installation.
