Air Purifiers for the Winter

While winter may not be thought of as an allergy season, it certainly creates challenges for homeowners who need clean, fresh air. The main culprits in winter tend to be allergic reactions from dust and pet dander. Indoor air pollution can be a serious problem, so make sure you have one of the best air purifiers to use in winter for your home.

The Challenges of Indoor Air in the Winter

Indoor air in the winter can be difficult to deal with. The biggest factor for indoor air quality in the winter months is the lack of circulation and air flow through the home because we close windows and the seal up the house to keep warm.

Indoor air in the winter means little circulation and less fresh air, which means there can be challenges when creating a plan to get rid of indoor air pollutants.

Winter generally has drier air in the home, which creates another set of air-quality challenges. You will want to ensure your relative humidity stays above 30%. If it falls lower then consider using a humidifier. Fortunately, there are some additional steps you take to get better air in the winter.

First, you need to limit the amount of indoor airborne particles, and for most this means reducing dust. In general, the majority of dust is from outside sources like sand and dirt, so making sure people remove their boots before entering the home is essential. You should also place mats on the interior and exterior of entryways to reduce dust. Clean and rotate these mats regularly to reduce winter dust and allergens in the home.

However, when it’s cold outside you will get more of your dust from inside the home. The main sources will be dust that has accumulated in your air ducts that is then blown throughout your home when the heat is turned on. The air filters for your furnace system often only remove the largest of dust particles and not the tiny airborne dust that causes most allergic reactions.

Another source is dust mites. For this we suggest regular washing of sheets and pillow cases. If you’re not sure whether you need an air purifier, you may want to conduct air quality testing.

Your best bet is to use an air purifier with a high efficiency air filter and a strong motor during the winter. These filters trap dust particles and create better breathing conditions inside. They can also be used to reduce airborne allergens, pet dander, pollen, and more, making them an effective tool during the winter.

Air purifiers are essential in the winter, so let’s look at how to choose the option for your home. With one of these outstanding air purifiers from Oransi, you’ll have cleaner air through the cold winter season!

How to Choose the Best Air Purifier to Use in Winter


The Clean Air Delivery Rate (CADR) rating is an official and regulated way of measuring an air purifiers performance. An air purifier company has to voluntarily submit their product to be reviewed by Association of Home Appliance Manufacturers (AHAM). The CADR rating reflects the volume of air in CFM (cubic feet per minute) that is cleaned of particles of certain sizes.

To measure the effectiveness in removing different particle sizes, three types of particles are tested: smoke, pollen and dust. These represent small, medium and large sized particles. Each is measured and assigned its own CADR score. 

The CADR is basically a reflection of the air flow (CFM) times the efficiency of the air filter. So, if an air filter has 200 CFM and 100% efficiency the CADR would be 200. If the air filter has 200 CFM and 75% efficiency the CADR would be 150.

Making sure your air purifier is going to clean your entire area efficiently is important when looking for the right air purifier for you. 

Filter Type

There are countless filter types in air purifiers and more new technology being developed. These new technologies might be appealing, but HEPA filter based media filtration is the proven air cleaning filter. 

This filter with an additional filter, like carbon-activated, is helpful for specific issues. Carbon-activated filters are going to help smoke concerns. If you enjoy wood burning or gas fire places in the winter, then it would be smart to look for an air purifier with high efficiency air filters and a strong motor to filter out pollutants created by smoke. 

Energy Star Certified

Devices can be Energy Star Certified meaning the device has been certified to use less energy than a certain threshold. Energy Star Certified means that the device you're buying saves energy and is a preferred product on the market. 

There are obvious advantages to buying an Energy Star Certified product like doing your part to help protect the environment. Buying an air purifier that is Energy Star Certified will help you save money especially in the winter when you're indoors and running your heater more often. 

AHAM Verifide 

AHAM (Association of Home Appliance) has particular standards they look for before they grant a product their certification. They mainly focus on measuring CADR (clean air delivery rate) of an air purifier.

Being AHAM Verifide is an official certification you can look for while looking for an air purifier to guarantee your product will perform as advertised. 

Value Price for Performance 

Once you've determined the CADR and square footage you need for your home or apartment it's time to figure out the best price for performance. There's a wide range of prices for air purifiers from inexpensive to extremely expensive. What's important is the ratio of cleaning power to the price. 

Finding a device in your budget that meets all of your needs might seem difficult but looking for certifications like AHAM Verifide and Energy Star is a great first step.
