Air Purifier for Asthma: Benefits and How to Choose

Choosing an Air Purifier for Allergies and Asthma

Most air purifiers are marketed towards allergens, odors, smoke even mold. However, just the mention of allergen removal might not be enough in your case. Here are a few essential things to look for:

  • True HEPA Filter

This filter will remove up to 99.97 to 99.99 percent of airborne particles (3). It captures everything from fine dust particles, dust mites and pet dander. A good pre-filter is also important as this will capture larger particles such as pollen, hair and dust.

  • Activated Charcoal or Carbon Filter

If you’re finding your allergies or asthma aggravated by certain odors, an activated charcoal filter is necessary. This filter absorbs odors such as smoke, cooking and even aromas caused by chemical cleaners.

Volatile organic compounds are domestic pollutants found in common household cleaners, sprays and other products. These can cause asthmatic and allergic reactions, as well. Activated carbon filters will also absorb VOCs and remove them from your environment.

  • Avoid Ionizers

You might think the air purifier will remove them before they drop to the ground, but that’s not always the case. When the particles become too heavy to float, the purifier can’t draw them in.

There’s a lot of debate on whether ionizers are helpful against allergens or not. However, the problem with ionizers is that they cause allergens such as dust to linger around. When the heavy particles fall to the ground, you have dust and allergens clinging to sofas, chairs, beds and floors, which require additional cleaning.
