Need an Air Purifier During Winter? Breathe Clean and Stay Healthy with Our Top-rated Products. Shop Now for Fresh Indoor Air!
We spend more time in the house as the air outside gets colder in winter. So, we need the indoor air warm, fresh, and clean.
During winter, there is more air pollution in the environment. The pollution also lasts longer because the cold air is denser. Along with the pollution comes a lot of problems for you and your pets.
The pollution that comes from the outside slips through into the house, and it takes time before it goes away. The winter air is also drier, which traps air pollution more and causes long-lasting air quality decline. The dry air could also cause skin problems for you and your family.
In this post, we’ll discuss why indoor air quality drops, how an air purifier can improve that quality, and how you can choose the right air purifier for your home.
TL;DR
In winter, indoor air can get worse because pollution and dry air stay trapped. This can cause allergies, breathing issues, and even seasonal depression. Air purifiers clean the air by removing bad smells and making it easier to breathe. Choose a purifier with a HEPA filter, which catches dust and particles without adding harmful chemicals. Regular maintenance will keep it working well.
Why Indoor Air Quality Deteriorates in Winter
Most people don’t know that air humidity and temperature can determine air pollution levels. Warm airs are light and flow easily. Cold air is dense and moves slowly compared to warm air.
Cold weather’s heaviness increases the pollution in two ways: by not letting the air move away and trapping the pollution.
The cold, heavy, and dense air sits below the warm air. So, two layers form in winter and colder weather: the warmer upper layer can flow but the colder air doesn’t. The pollution from the lower layer can’t get to the upper (flowy) air and sits in the lower layer.
Another reason for poor air quality in winter is its dry weather.
Rain washes away the pollution in the environment. Humidity in hot weather has the same effect. Humidity and rain are both low in winter. So, winter has less of a “washaway” effect.
The trapped pollutants in winter eventually enter the home. The condition then becomes worse indoors because of sealed windows and limited ventilation. As a result, it can cause several health issues like:
- Flu or cold
- Respiratory issues like asthma, bronchitis, etc.
- Dry skin
How Air Purifiers Help During Winter?
We have already mentioned how the winter weather especially can cause poor air quality. The pollutants along with dust, debris, etc. get stagnant in the environment. Eventually, they circulate indoors through the HVAC inlets.
Air purifiers in the HVAC system clean most of the pollutants from the air. Here are some benefits of having an air purifier, especially during the winter:
1. They reduce indoor odors
When you and your pets are in the house all day, it adds pollutants and makes the air in the house stuffy. The stuffiness could eventually result in unpleasant odors throughout the house.
You can experience fresher air with air purifiers that target bacteria and allergens. Also, the air purifier eliminates stiffness from the indoor environment.
2. They help reduce cold weather allergies
Allergies are worse during the winter, mainly because of mold and dust build-up in the house. As you remain indoors, the house temperatures can also get high. The situation creates the perfect condition for dust mites.
Some dust releases can also happen after you turn on your previously dormant furnace.
Since pets are also indoors, there will be an increase in pet dander around the house. The dust mites and pet dander cause or aggravate allergies and asthma symptoms.
Air purifiers remove the contaminants before they can affect your health. Some air purifiers even use HEPA filters which are highly effective in trapping even tiny dust particles. So, you get exposed less to all the contaminants with an air filter.
3. Helps alleviate winter depression
This is also known as seasonal depression. The seasonal affective disorder can happen in any season and has different symptoms. The most common symptoms are overeating, low energy levels, and sleep issues during the winter.
You can sleep better with the environment the air purifier creates indoors. Cleaner air also helps improve your energy levels, which eventually helps you overcome the winter depression.
Choosing the Right Air Purifier for Winter

Whether you are convinced to get an air purifier or are already shopping for one, you need to consider several factors before buying.
Here are some factors to consider before choosing the right air purifier for your home:
- Type of filtration
- Size of the room
- Installation and maintenance budget
- Placement in the room
- Noise level
- Preference for extra and smart features
When buying an air filter, differentiate between air purifiers with HEPA filters and ionic air filters. Ionic air filters create ozone, which is a harmful air pollutant.
Therefore, always lean towards the ones with HEPA filters like the Lennox air purifiers The Chill Brothers will install in your house.
You can also call them before you install your air filters to determine which one is the best for you, depending on your needs and the size of your house. They can also conduct a free air quality test free of charge.
Conclusion
The winter season is pollution-heavy due to low humidity and temperature. An air purifier reduces the air contaminants and stiffness in your home. So, you can enjoy a healthier home environment. Be sure to check for a proper air purifier when you intend to invest in one.
After having your air filter running for some time, it could accumulate a lot of dust and debris in the filter, which could reduce its effectiveness in cleaning your indoor air. Therefore, you need to contact The Chill Brothers a Houston local HVAC company to come out and look at your air purifier and filters often.
