How To Improve Your Indoor Air Quality This Winter (2025) 

Breathing clean, healthy air has become increasingly important as we learn more about how it impacts our health. During the winter, when we have the windows closed and spend the majority of our time indoors, breathing clean air at home becomes even more important to staying healthy and feeling good! 

We’ve been working in the Havertown area since 1953, helping keep homes and businesses warm during the winter and cool during the summer. We also specialize in indoor air quality, which has become so much more of a concern in the past few years. Keeping the air clean leads to improved health, fewer coughs and colds, and generally feeling better. It’s also great for furniture and keeping the indoor environment smelling better and maintaining your possessions. 

If you want to keep the air in your home clean and healthy, give us a call at (610) 446-7877, or contact us online. We can help you with indoor air quality products like air filters and purifiers, or schedule routine maintenance for your HVAC systems. 

How To Keep The Air Clean In Your Home

There are a number of ways you can keep the air clean in your home, and we’ll go over a few here. During the winter, it’s especially important to make sure you are taking steps to keeping the air clean. When it starts to get cold, we close the windows and turn the heat up. This is great for feeling cozy, but it also leads to you circulating the same air around your home. If that air isn’t clean, it means you are breathing unnecessary bacteria, dust, allergens, etc. 

Typically, in the spring or fall, you can open the windows to circulate some fresh air. It’s estimated that the air inside your home is anywhere between 2-5X more polluted than the air outside. This means that with sealed windows to keep the warm air in, it leads to dirtier air, unless of course, you have methods to clean it. 

Here are a few of the best ways to keep the air clean in your home this winter: 

Change Your Air Filter

Changing your air filter is a simple and effective way to keep the air in your home clean. We recommend you change the air filter once every 1-3 months, depending on the conditions. Changing the air filter is something you can do on your own. Buy a few and keep them on hand so you don’t have to run to the store or order a single one every time. 

Over time, an air filter can get clogged when it fills up with dirt, dust, pet dander, etc. If you don’t have the filter changed regularly, it’s going to impact the air quality in your home, as well as the airflow in your HVAC system. 

The air filter sits in your HVAC system, and can easily be removed and replaced. If you aren’t sure how to replace your air filter, you can ask your HVAC technician during a service. You can also check out our video on changing an air filter here:

Scheduling HVAC Service 

Scheduling regular maintenance for your heating system is a great start to keeping the air in your home clean. When you have your HVAC system serviced, that comes along with cleaning and inspection. Any soot or buildup is wiped away, and all the components are cleaned. We also change the air filter, and make sure the system is running properly. 

Along with cleaner air, annual maintenance also comes with other benefits:

• Extends a system’s lifespan 
• Improved energy efficiency
• Maintains your warranty 
• Ensures safe operation
• Reduces the chance of a breakdown

Add A Humidifier 

Controlling the humidity in your home is important during the winter. Most people simply think of high humidity during the summer, and how uncomfortable it makes you feel. In our area of Pennsylvania, we see some serious swings in humidity throughout the seasons. 

During the winter, low humidity can lead to health and comfort issues: 

• Dry skin
• Breathing issues
• Dry sinuses 
• Dry eyes
• Nose bleeds 
• Furniture issues, wood damage, cracking paint, etc. 

Adding a humidifier to your home will help regulate humidity, and ensure that you are sitting between 30-50% humidity, where you should be. This is also going to help it feel warmer and more comfortable as well! 

Install A Ventilation System

Fresh air is the best way to clean the air in your home. The problem is when it’s very cold outside, you aren’t opening the windows and circulating and fresh air. In this case, we recommend installing systems like energy recovery ventilators (ERVs) or heat recovery ventilators (HRVs). These systems exchange stale indoor air with fresh outdoor air while reducing the amount of energy loss from your heating or cooling system. 

This is a perfect way to keep your space warm, but also incorporate fresh air into your living space. 

Installing An Air Purification System

Air purification systems are designed to actively clean the air in your home. Unlike a filter that catches particles that pass through it, purification systems use different methods to attack the airborne irritants floating around your space. Some of these use UV lights that eradicate small particles, and some use technology that sends ions into the air that attack the dirt particles. 

Some systems work better than others, and you may want to explore some options that fit your space best.
