Signs of Poor Indoor Air Quality in Your Home
Your indoor air quality (IAQ) directly impacts your health. The US Environmental Protection Agency found that poor IAQ can cause symptoms ranging from mild throat irritation to more severe issues such as respiratory disease.
Dauenhauer recommends Louisville air quality testing to have your IAQ assessed if you’ve experienced the following:
- New allergies or an increase in symptoms
- Living in an older home (these typically have less advanced ventilation systems and/or are more likely to have been built with hazardous materials)
- Constant illness with no known cause
- Moving into a new home and want a healthy start
No matter the reason your home has poor IAQ, you want to get it addressed sooner rather than later. Dauenhauer provides air purification services Louisville and Lexington residents can trust.
Air Purifier Installation
If you’re ready to install or update your air purification system to improve your IAQ, Dauenhauer is here.
Air purifiers use very fine mesh to filter pollutants out of the air. Our technicians find the most effective systems actively exchange indoor and outdoor air, remove contaminants, temper humidity, and kill germs, such as bacteria and viruses.
By installing a new air purifier in your Louisville home, you can experience the following benefits:
- Improved allergy symptoms
- Improved air circulation
- Decreased dust in the home
- Mold and mildew prevention
One of our Louisville air purification experts is ready to help you find the right system to keep your family healthy.
Air Purifier FAQs
Do air purifiers really work?
Yes — for the specific pollutants they’re rated for, in the room size they’re sized for. True HEPA filters capture 99.97% of particles ≥ 0.3 microns (the MPPS — most-penetrating particle size), and AHAM-verified CADR ratings tell you exactly how many cubic feet per minute of smoke, dust and pollen a given unit can clean. Studies cited by the EPA show that, when properly sized to the room, portable HEPA units cut particulate (PM2.5) in the room by 50–90% during wildfire smoke and allergy events. They do not remove gases (VOCs, CO) unless they include an activated-carbon stage, and none substitute for source control and ventilation.
Do air purifiers help with allergies?
For airborne allergens — pollen, pet dander, dust-mite debris, mold spores — yes, a correctly sized HEPA unit running continuously in the bedroom shows measurable reduction in symptoms for most allergy sufferers in peer-reviewed studies. For dust-mite and pet-dander allergies that are heavily bed/couch-bound (not airborne), an air purifier helps only modestly — washing bedding in 130°F+ water, HEPA vacuuming upholstery, and maintaining 30–50% indoor humidity matter more. Run the purifier at the highest fan speed you can tolerate at night (the room air must be exchanged 4–5 times per hour for best results).
What’s the difference between a HEPA filter and a MERV 13 filter?
MERV is the ASHRAE 52.2 rating scale (1–16 for residential) that describes how much of a given particle size a filter captures. A true HEPA filter removes 99.97% of 0.3-micron particles — equivalent to roughly MERV 17–20, which is higher than any filter your residential HVAC blower can push air through without restriction. For central HVAC filtration, MERV 11–13 is the sweet spot: MERV 13 captures about 90% of airborne viruses and >75% of bacteria-sized particles while keeping static pressure within most residential blower specs. Go above MERV 13 only if an HVAC tech has measured your static pressure and confirmed the blower can handle it.
What’s the difference between a whole-home air purifier and a portable one?
A portable air purifier (Coway, Levoit, Blueair, Winix, IQAir, Molekule) sits in one room, runs 24/7, and has an AHAM-verified CADR rating for that room size. A whole-home air purifier is installed in the return duct and cleans every cubic foot of air that passes through the HVAC system — it only runs when the HVAC blower runs, so pair it with “fan on” or a variable-speed blower. Whole-home units work best in layered systems: MERV 13 prefilter + HEPA bypass + optional UV-C or UL 2998-certified ionizer.
