How Better Ventilation Can Help Reduce Allergens in Your Home
When allergy season hits, you may think of pollen as something you leave outside when you close the front door. Unfortunately, allergens have a way of following you home. Pollen can hitch a ride on shoes, clothing and pets. Dust and pet dander are already present indoors. Add humidity, everyday household activities and an HVAC system that is not moving or filtering air effectively, and the air inside your home may not feel like much of an escape.
Opening the Windows Is Not Always the Answer
Fresh air sounds like the obvious solution, but during a heavy pollen day, opening every window may simply invite more allergens inside. The same goes for days with poor outdoor air quality, smoke or high humidity.
So, understanding how your HVAC system manages airflow is the first step in learning how to improve ventilation in the home.
Ventilation Helps Move Stale Indoor Air Out
Your home naturally collects airborne particles, odors, moisture and pollutants throughout the day. Cooking, cleaning, showering, using household products and simply living in the space all affect indoor air quality. Ventilation helps exchange stale indoor air for cleaner outdoor air and exhaust pollutants from areas where they are produced.
Kitchen and bathroom exhaust fans are good examples. When properly vented outdoors, they help remove cooking contaminants and excess moisture before those substances have a chance to circulate throughout the house.
This is especially important here in Louisiana, where high indoor humidity can create conditions where mold and dust mites thrive, both of which can make allergy symptoms worse.
Ventilation and Filtration Work Better Together
Ventilation brings air in and moves stale air out. Filtration helps capture particles as air circulates through your HVAC system. Together, they can help reduce the amount of pollen, dust, pet dander and other particles circulating through your home.
A clean HVAC filter can help capture some of those particles before they continue circulating through your home. However, the highest-rated filter is not automatically the best filter for every HVAC system. Filters that are too restrictive can interfere with airflow if the system was not designed to accommodate them.
Simple Ways to Improve Ventilation in the Home
You do not necessarily need to make major changes to improve airflow and indoor air quality.
Start with a few basics:
- Use bathroom exhaust fans during and after showers.
- Run the kitchen exhaust fan when cooking, especially if it vents outdoors.
- Replace or clean HVAC filters according to the manufacturer’s recommendations and conditions in your home.
- Keep supply and return vents clear of furniture, rugs and other obstructions.
- Address moisture problems and indoor humidity.
- Have your HVAC system maintained regularly so airflow and equipment performance can be checked.
It also helps to reduce allergens at the source. Remove shoes at the door during pollen season, wash bedding regularly, vacuum frequently and keep pets groomed to reduce the amount of material your HVAC system has to handle.
Is Your Home Getting Enough Fresh Air?
Today’s homes can be well sealed for energy efficiency, which is great for keeping conditioned air inside. But a tighter home can also hold onto moisture, odors and indoor pollutants when ventilation is inadequate. If your home often feels stuffy, humid or musty, or your allergy symptoms seem worse indoors, it may be worth having your HVAC system and indoor air quality evaluated.
