Indoor Air Can Be Up to 5 Times More Polluted Than Outdoor Air
According to the EPA, levels of some pollutants indoors can be two to five times higher than outdoors. Most of us spend the majority of our time inside, so cleaner indoor air is one of the most practical ways to protect your family’s long-term health.
Common Indoor Air Pollutants
Every home collects
dust, pollen, and pet dander
, which can trigger allergy and asthma symptoms. Many homes also contain
VOCs and household chemicals
released by cleaning products, paint, and new furniture. In damp areas,
mold spores, bacteria, and viruses
can grow and then circulate through your ductwork to every room.
Whole-Home Air Filtration Systems in Bloomington and Peoria
Many airborne particles are small enough to slip through an ordinary furnace filter. A whole-home filtration system captures far more of them every time air passes through your HVAC system.
High-MERV Media Filters
A filter’s MERV rating tells you how well it captures small particles, and higher numbers catch more. We help you choose a filter your system can handle without restricting airflow.
Electronic Air Cleaners and Dedicated Air Purifiers
For even cleaner air, we install whole-home air cleaners such as the Trane CleanEffects system, along with the REME HALO-LED in-duct air purifier. Learn more about the equipment we carry on our Trane systems page.
Breathe Easier With the REME HALO® Zero
Filters capture particles, but they cannot stop germs and odors on their own. The REME HALO® Zero is the next generation of whole-home air purification, working inside your ductwork to clean the air in every room.
How REME HALO Technology Works
The REME HALO® Zero combines UVC light, advanced catalysts, and low-level airborne hydrogen peroxide to reduce allergens, bacteria, viruses, mold spores, and odors. It has verified zero ozone emissions, a built-in timer that reminds you when the cell needs replacing, and a 5-year limited warranty.
UV Light Air Purification for Bloomington and Peoria Homes
UV light air purification targets microorganisms as air moves through your HVAC system. It also helps keep the indoor coil free of growth, which supports efficient operation over time.
Whole-Home Humidifier Installation in Bloomington and Peoria
Humidity affects comfort as much as temperature does, and Central Illinois homes swing from too dry in winter to too damp in summer.
Why Illinois Winters Dry Out Your Home
Cold outdoor air holds very little moisture, and heating it drops indoor humidity even further. Below about 30 percent, many people notice dry skin, irritated eyes and sinuses, and static shocks.
Bypass vs. Steam Humidifiers
A bypass humidifier uses your furnace’s airflow to add moisture and is simple to maintain. A steam humidifier produces moisture on its own, giving you more precise control. We also install fan-powered models.
Whole-Home Dehumidifiers for Humid Summers
Summer humidity makes a home feel warmer than it is, encourages mold, and can damage wood floors. The Trane Whole Home Dehumidifier removes excess moisture without leaving the air uncomfortably dry.
Freshen Up Your Home With Improved Ventilation
Modern homes are sealed tightly to save energy, but that can trap pollutants inside. Whole-house ventilation steadily replaces stale indoor air with fresh outdoor air, and our blog explains whether a whole-home ventilator could benefit your household.
Energy Recovery Ventilators (ERVs)
An ERV transfers both heat and moisture between incoming and outgoing air. That pre-conditions the fresh air and reduces the load on your heating and cooling system.
Heat Recovery Ventilators (HRVs)
An HRV transfers heat between the two airstreams but not moisture, which makes it a good fit for homes that tend to stay humid in winter.
Air Duct Cleaning Services in Bloomington, IL
Over the years, dust and debris settle inside your ductwork. Professional duct cleaning removes that buildup and pairs well with the filtration and purification upgrades above.
Signs Your Ducts Need Cleaning
Visible dust around the vents, musty odors when the system runs, or a recent renovation are all good reasons to have your ducts cleaned.
What Our Duct Cleaning Includes
We clean both the supply and return ducts and inspect for leaks or damage while we are there.
FAQs About Indoor Air Quality
What indoor humidity level is best in winter?
The EPA recommends keeping indoor humidity between 30 and 50 percent.
How often should I replace my air filter?
Check a standard 1-inch filter monthly and replace it every one to three months. Thicker media filters last longer.
Do whole-home air purifiers help with allergies?
Whole-home filtration and purification can reduce airborne allergens such as dust, pollen, and pet dander throughout your home.
Breathe Easier at Home
Cleaner, healthier air is easier to achieve than you might think. Request an appointment or call (309) 485-5848 to schedule an indoor air quality visit in Bloomington, Peoria, or the surrounding area.
This in-duct air purifier uses a powerful combination of UVC light, advanced catalysts, and low-level airborne hydrogen peroxide to actively target and reduce allergens, bacteria, viruses, mold spores, and odors throughout your home. With its revolutionary aGHP® technology and verified zero ozone emissions, the REME HALO® Zero offers continuous, safe air purification for your entire air-conditioned space.

Indoor Air Can Be Up to 5 Times More Polluted Than Outdoor Air
Making clean indoor environments is essential for your long-term health
Traditional filters often miss microscopic pollutants, allowing contaminants to build up and recirculate. The REME HALO® Zero directly addresses this problem by purifying the air at the source. Whether you’re trying to eliminate pet odors, fight off airborne germs, or simply enjoy fresher, cleaner air, this system transforms your home’s environment—and you’ll wonder why you didn’t make the upgrade sooner.
Take Charge of Indoor Humidity Control
Summertime humidity is a chronic issue in Central Illinois, amplifying the heat and fostering favorable conditions for organic growth. Over time, it can even damage wood floors and furniture. One foolproof way to fix the problem is to add a dependable dehumidifier. The Trane Whole Home Dehumidifier excels at controlling excessive humidity, whisking away moisture without leaving the air unpleasantly dry.
Speaking of which, low humidity levels can also wreak havoc on indoor air quality. Below about 30%, you’ll likely experience effects ranging from dry eyes and nosebleeds to worsening asthma and allergy symptoms. We carry a number of effective solutions to help you get through the winter, including steam, bypass, and fan-powered humidifiers.
Freshen Up Your Home With Improved Ventilation
We all need a little fresh air from time to time. Unfortunately, many modern homes are deliberately sealed up tight to increase energy efficiency. An unintended consequence of this design philosophy is that it often leaves harmful gases and particles with no way to escape.
Whole-house ventilation systems solve this problem by continuously carrying away stale indoor air and replacing it with fresh air from outdoors. Not only does this reduce the concentrations of pollutants, but it also works to keep humidity levels in check. With an energy recovery ventilator, you can even save money and help out your HVAC system by pre-conditioning the incoming fresh air.
