  • Remove allergens from the air, reducing allergy symptoms

Choosing the Right Air Purifier for Allergies and Asthma

When it comes to choosing the right air purifier for allergies and asthma, there are several key factors to consider. These factors will help ensure that the air purifier you choose is effective in improving your indoor air quality and reducing your allergy and asthma symptoms.

Size of the Room

The size of the room where you plan to use the air purifier is a crucial factor. Air purifiers are designed to clean the air in a specific square footage. Therefore, you need to ensure that the air purifier you choose is capable of handling the size of your room. For larger rooms, you may need a more powerful air purifier or even multiple units.

Type of Filter

The type of filter used in the air purifier is another important consideration. HEPA filters (High Efficiency Particulate Air filters) are considered the gold standard for air purifiers as they can trap 99.97% of particles that are 0.3 microns in size. However, some air purifiers use other types of filters, such as activated carbon filters for odor removal or UV-C light filters for germ killing.

Noise Level

Noise level is a factor that is often overlooked but can significantly impact your comfort, especially if you plan to use the air purifier in your bedroom or living room. Some air purifiers can be quite loud, especially on higher settings. Therefore, it’s worth checking the noise level (measured in decibels, dB) before making a purchase.

Energy Efficiency

Energy efficiency is another factor to consider, especially if you plan to run the air purifier for extended periods. Look for air purifiers that are Energy Star certified, as these models are designed to be more energy-efficient.

Cost and Maintenance

The upfront cost of the air purifier is not the only expense to consider. You should also factor in the cost of replacement filters and the frequency of replacement. Some air purifiers may have cheaper upfront costs but require expensive filters that need to be replaced frequently.

Additional Features

Additional Features such as air quality sensors, filter change indicators, programmable timers, and multiple fan speeds can also enhance the functionality and convenience of the air purifier.

Choosing the right air purifier for allergies and asthma involves considering the size of your room, the type of filter, the noise level, energy efficiency, cost and maintenance, and any additional Features. By taking these factors into account, you can find an air purifier that meets your specific needs and helps improve your indoor air quality.

Remember, living with allergies and asthma can be a real drag, but it doesn’t have to be. With the right air purifier, you can take a deep, clean breath and say, “Heaven forbid! I’ve got this!”.

While air purifiers are effective at reducing airborne allergens and pollutants, they cannot completely eliminate them. It’s important to also practice good hygiene habits like regularly vacuuming and dusting, washing bedding frequently, and minimizing clutter in your home.


How often should I replace the filter in my air purifier for allergies and asthma?

It depends on the type of filter, but generally HEPA filters should be replaced every 6-12 months and activated carbon filters every 3-6 months. Some newer air purifiers have sensors that can detect when the filter needs to be replaced.

Can an air purifier completely eliminate allergens or asthma triggers from a room?

While air purifiers are effective at reducing airborne allergens and pollutants, they cannot completely eliminate them. It’s important to also practice good hygiene habits like regularly vacuuming and dusting, washing bedding frequently, and minimizing clutter in your home.

Are expensive air purifiers always better for allergies and asthma sufferers?

Not necessarily. The most important factor in choosing an effective air purifier is its ability to remove specific allergens or pollutants from the air (such as pollen, pet dander, or smoke). Look for models with high CADR ratings (Clean Air Delivery Rate) which indicates how efficiently it can clean a certain amount of cubic feet per minute. Price is not always an indicator of performance.
