CNA Explains: How to choose an air purifier and what to look out for

Hey there! I’m excited to talk to you about something that is very important for our health and well-being – choosing the right air purifier. With pollution levels on the rise and respiratory issues becoming more common, having a good air purifier in your home can make a world of difference.

But with so many options available in the market, it can be overwhelming to figure out which air purifier is the best for you. That’s where I come in! In this video, I’ll be explaining how to choose an air purifier and what to look out for. So grab a pen and paper, and let’s get started!

Types of Air Purifiers

Before we dive into the specifics of what to look for in an air purifier, let’s first understand the different types of air purifiers available. Broadly speaking, there are three main types of air purifiers – HEPA, ionizers, and activated carbon filters.

HEPA filters are considered the gold standard in air purification. They are capable of trapping 99.97% of particles as small as 0.3 microns, including dust, pollen, pet dander, and mold spores. If you have allergies or asthma, a HEPA filter is highly recommended.

Ionizers work by releasing negative ions into the air, which attach to positively charged particles like dust and allergens, causing them to fall to the ground. While ionizers are effective at removing airborne particles, they produce ozone as a byproduct, which can be harmful to people with respiratory issues.

Activated carbon filters are excellent at removing odors and gases from the air, making them ideal for households with pets or smokers. They work by adsorbing the particles onto the carbon surface, effectively neutralizing them.

Factors to Consider When Choosing an Air Purifier

Now that you know the different types of air purifiers, let’s discuss the factors to consider when choosing the right one for your home:

Room Size

The first thing to consider is the size of the room where you will be placing the air purifier. Air purifiers are designed to cover a specific square footage, so it’s important to choose one that is appropriate for the size of the room. If you’re not sure about the square footage of your room, you can measure it by multiplying the length and width. For example, a room that is 10 feet by 12 feet has a square footage of 120 square feet.

Clean Air Delivery Rate (CADR)

The Clean Air Delivery Rate (CADR) measures how efficiently an air purifier can clean the air in a room. It is expressed in cubic feet per minute (CFM) and is calculated for three main types of particles – dust, pollen, and smoke. The higher the CADR, the faster the air purifier can clean the air in your room.

Noise Level

Some air purifiers can be quite noisy, especially when running at the highest speed. If you plan on using the air purifier in a bedroom or living room, consider the noise level before making a purchase. Look for models that have a quiet operation mode or adjustable fan speeds.

Energy Efficiency

Since air purifiers run continuously, they can consume a significant amount of electricity. Look for models that are Energy Star certified, as they are more energy-efficient and will save you money in the long run. Additionally, choose an air purifier with a programmable timer, so you can set it to run only when needed.

Filter Replacement

All air purifiers come with filters that need to be replaced periodically to maintain their effectiveness. Some models have reusable filters that can be cleaned and reinstalled, while others require regular replacements. Consider the cost and availability of replacement filters before making a purchase.

Additional Features

Lastly, consider any additional features that are important to you. Some air purifiers come with built-in air quality sensors that automatically adjust the fan speed based on the level of pollutants in the air. Others have a UV-C light that can kill germs and bacteria. Choose a model that has the features that are relevant to your needs.

Conclusion

Choosing the right air purifier can be a daunting task, but by considering the factors mentioned above, you can make an informed decision. Remember to select an air purifier that is suitable for the size of your room, has a high CADR, operates quietly, is energy-efficient, and has easy-to-replace filters.
