As winter settles in across Louisville and temperatures start to dip, most of us begin spending significantly more time indoors. While your HVAC system keeps your home warm and comfortable, it can also circulate dust, allergens, and other airborne contaminants—especially when windows stay shut for months at a time.
If you’ve ever noticed more sneezing, dry air, or stale odors during the winter, you’re not alone. Winter is the most important time of year to evaluate your home’s indoor air quality (IAQ). The good news? Today’s HVAC accessories make it easier than ever to keep your home’s air clean, fresh, and healthy.
Here are our top recommended products to help improve indoor air quality before winter hits.
1. Reme Halo® Whole Home Air Purification System
One of the most effective IAQ solutions available today is the Reme Halo®, a Whole Home Air Purification System that installs directly into your HVAC system’s ductwork. Once installed, it works continuously whenever your system is running.
The Reme Halo® is capable of removing up to 98% of irritating airborne particles, including:
- Dust
- Pet dander
- Pollen
- Smoke
- Mold spores
- Bacteria
- Some viruses
For Louisville-area homeowners who struggle with allergies or asthma, this can be a game changer. By neutralizing pollutants right in the air stream, the Reme Halo® dramatically improves air quality and helps reduce respiratory irritation.
It’s also an ideal add-on for pet owners, as it helps capture and neutralize odors and allergens that come from furry family members.
2. High-Efficiency HVAC Air Filters
A simple filter upgrade can make a big difference. Standard fiberglass filters only trap the largest particles, offering minimal IAQ benefits. Upgrading to a high-efficiency pleated filter—ideally with a MERV rating between 11 and 13—captures smaller contaminants like pet dander, smoke, and dust mites.
For best results during winter, we recommend changing your filter every 1–2 months, especially if you have pets or suffer from seasonal allergies.
3. Whole-Home Humidifiers
Dry winter air is a common Louisville complaint. Low humidity can lead to:
- Dry skin
- Throat irritation
- Static electricity
- Warped wood floors
- Increased spread of airborne viruses
A whole-home humidifier connects directly to your heating system, adding just the right amount of moisture to the air as it circulates through your home. This not only helps you feel more comfortable but can also improve the efficiency of your heating system.
4. UV Air Sanitizer Lights
Installed inside your HVAC system near the indoor coil, ultraviolet (UV) lights kill mold, mildew, and bacterial growth before they can circulate through your home. This helps keep your system clean and improves airflow, while also preventing musty odors common in winter.
5. Air Quality Monitoring Devices
If you’re unsure what’s in your home’s air, an indoor air quality monitor can be a helpful tool. These smart devices track:
- Particulate levels
- Humidity
- VOCs (volatile organic compounds)
- Temperature
Monitoring your indoor air gives you a clear picture of problem areas and helps you decide which IAQ solutions are right for your home.
