Air quality plays a crucial role in your overall health, especially when it comes to your home. In Knoxville, Tennessee, the seasonal climate and surrounding natural elements contribute to a variety of indoor air quality challenges, from pollen and humidity to dust and mold. Fortunately, there are many simple and effective ways to improve the air you and your family breathe every day.
If you're a Knoxville homeowner or planning to buy a home in the area, this guide will walk you through practical steps to enhance indoor air quality. These improvements promote better health and add comfort and value to your living space.
Understand the Common Indoor Pollutants in Knoxville
Knoxville’s beautiful location near the Great Smoky Mountains provides stunning scenery, but it also means higher-than-average pollen levels, especially in the spring and fall. In addition to pollen, homes in East Tennessee often contend with:
- Dust and pet dander
- Mold and mildew from humidity
- Volatile organic compounds (VOCs) from cleaning products and building materials
- Smoke from wood-burning fireplaces or nearby outdoor burning
Understanding these common pollutants is the first step to eliminating or reducing them. Regular home maintenance and mindful habits can go a long way in improving air quality indoors.
Replace HVAC Filters Regularly
Your heating and cooling system plays a huge role in circulating air throughout your home. One of the easiest and most effective ways to maintain clean air is to replace or clean your HVAC filters every one to three months.
In Knoxville, where homes often rely on central air systems to manage both summer heat and winter cold, filters can get clogged quickly with dust, pollen, and pet hair. Choose high-quality filters with a MERV rating of at least 8 or 9. For those with allergies or respiratory sensitivities, a HEPA filter may be worth the upgrade.
Invest in an Air Purifier
Air purifiers are an excellent tool for homes with allergy sufferers or for families who want to reduce airborne particles like dust, pollen, smoke, and even bacteria.
For Knoxville residents, this can be especially useful during spring and fall allergy seasons. Portable air purifiers can be used in bedrooms, living rooms, or nurseries, while whole-home air purification systems can be integrated directly into your HVAC unit.
Look for purifiers with HEPA filters and carbon filters, which can trap particles as small as 0.3 microns and absorb odors and gases.
Control Humidity Levels
Humidity is a big concern in East Tennessee due to the region’s subtropical climate. High indoor humidity can promote mold growth, dust mites, and mildew, all of which worsen air quality and aggravate asthma or allergy symptoms.
A comfortable humidity level for most homes is between 30 and 50 percent. In Knoxville, this can be difficult to maintain during muggy summer months, so consider installing a dehumidifier, particularly in the basement or other areas prone to moisture buildup.
Whole-house dehumidifiers work in tandem with your HVAC system, while portable units can target specific trouble areas. Be sure to empty and clean the water reservoir regularly to avoid bacteria buildup.
Use Low-VOC or VOC-Free Products
Many household items release volatile organic compounds into the air, which can cause headaches, dizziness, and long-term health issues with prolonged exposure. These products include:
- Paints and varnishes
- Cleaning agents
- Air fresheners
- Furniture and carpets treated with chemicals
Opt for low-VOC or VOC-free alternatives whenever possible. Many Knoxville retailers now carry eco-friendly paints and cleaners that are just as effective but far safer for indoor air. Ventilate the home during and after any painting or deep cleaning project to allow any lingering VOCs to dissipate.
Add Indoor Plants Thoughtfully
Plants are not only beautiful and calming; they can also help purify the air. Certain houseplants, such as peace lilies, spider plants, and snake plants, can filter toxins such as formaldehyde and benzene.
That said, not all plants are ideal for allergy sufferers. Some may produce pollen or collect dust on their leaves. If allergies are a concern, choose hypoallergenic varieties and wipe down the leaves regularly.
Keep in mind that Knoxville’s natural environment already delivers high pollen levels seasonally, so balancing indoor greenery with good airflow is key.
Improve Ventilation
Proper ventilation helps dilute and remove indoor air pollutants. In newer homes, especially those built with energy efficiency in mind, airflow can be limited. This makes mechanical ventilation more important than ever.
Use exhaust fans in the kitchen and bathrooms to vent out moisture and cooking fumes. When the weather permits, open windows to let fresh air in and flush stale air out.
In Knoxville, spring and fall are great seasons to air out the home, as outdoor temperatures are mild and pollen levels can be managed with timing and screens. Avoid opening windows early in the morning or late afternoon during high-pollen days.
Keep Floors and Surfaces Clean
A consistent cleaning routine helps prevent the buildup of allergens and contaminants. Start with a good vacuum equipped with a HEPA filter. Vacuum carpets, rugs, and upholstered furniture weekly to reduce dust mites and pet dander.
Hardwood or tile floors can be swept and mopped regularly using non-toxic cleaners. Be sure to dust all surfaces, including baseboards, ceiling fans, and window sills, where allergens tend to settle.
In Knoxville’s allergy-prone climate, frequent cleaning during spring and fall months is especially helpful in minimizing indoor irritants.
Schedule an HVAC Inspection
Twice-yearly HVAC inspections are a smart way to keep your system running efficiently and maintain healthy air circulation. A professional technician can check for duct leaks, clean coils, and recommend additional filtration upgrades.
If your home has never had a duct cleaning or if you’ve recently completed a renovation, scheduling a full cleaning may help remove built-up dust, construction debris, or mold.
Consider a Home Air Quality Test
If you or a family member has ongoing respiratory issues or allergies and you’ve already implemented air-improvement strategies, a home air quality test may help uncover hidden sources of irritation.
These tests can detect mold spores, carbon monoxide, VOC levels, and other contaminants. They can also reveal if your HVAC system is effectively filtering the air or if you need to take additional steps.
Many Knoxville-area HVAC providers or environmental inspection companies offer these tests and can help interpret the results.
