Why You Should Buy One Of The Best Air Purifiers For Asthma

You might be doubtful about the benefits of an air purifier. Below are the reasons why buying one of the above best air purifiers can help with your allergies, asthma, and other respiratory ailments:

why you should buy one of the best air purifiers for asthma

1. Effects Of Poor Indoor Air Quality 

Poor indoor air quality causes: 

  • Adverse asthma, allergies, and respiratory diseases.
  • Headache, nausea, and fatigue.
  • Concentration issues.
  • Irritation to eyes, nose, throat, and lungs.
  • Shortness of breath.
  • Sneezing and coughing.

2. Causes Of Poor Indoor Air Quality

The causes of poor air quality are:

  • Dust and debris floating around in the air lower its quality.
  • Many household items like cleaning products, furniture, and paints release VOCs (Volatile Organic Compounds) in the air. 
  • Pet hair, dander, and odor are detrimental to indoor air quality and are a big reason for allergy symptoms.
  • Dust mites, mold spores, and pollen are bad for your lung’s health.

3. Air Filtration Removes Harmful Airborne Particles

Air purifiers have air filtration systems. Here is how they clean the air:

  • The filtration system in air purifiers removes dust, smoke, VOCs, unwanted odors, mold spores, pollen, bacteria, germs, and viruses from the air and releases clean and fresh air back into the environment.
  • Breathing in clean air is crucial for good lung health.
  • While the outdoor environment is not in your control, you can improve indoor air quality by investing in a good air purifier. Hence, buying an air purifier is a wise choice.

Key Factors To Look Out For The Best Air Purifier For Asthma

The key factors you must consider while buying the best air purifier for asthma or allergy are as follows:

Key Factors To Look Out For The Best Air Purifier For Asthma

1. High-Efficiency Carbon Filter 

Carbon filters reduce unpleasant odors and VOC from the air. VOCs are a primary reason for poor indoor air quality. Look out for a carbon filter with highly adsorbent carbon pellets.

2. True HEPA Filter

HEPA (High-Efficiency Particulate Air) filters trap ultra-fine particles like mold spores, pet dander, pollen, bacteria, dust mites, and viruses that trigger allergy symptoms and asthma attacks. Look out for a HEPA filter with at least a 95% particle retention rate.

3. Air Cleaning Performance

CADR (Clean Air Delivery Rate) finds out how effective an air purifier is at removing dust, smoke particles, pollen, and other particles from the air. Look out for air purifiers with higher CADR.

4. Electronic Air Purifiers Vs Ozone Generators

Electronic air purifiers release particles with an electric charge to magnetically pull indoor air pollutants toward the air purifier and stick to it. 

Ozone generators produce ozone (O3) that oxidizes airborne contaminants and eliminates them. They produce very low ozone, yet exposure to it can worsen your health. Your pets might suffer too. Be careful while selecting air purifiers with such technologies.

5. Ultraviolet Light Technology

Air purifiers with UV light expose the air input to UV rays that kill off germs, bacteria, and viruses. It is safe to use.

6. Room Coverage 

Pay special attention to the room coverage of the air cleaner. If you get a small air purifier for a large room, it will fail to purify the complete airflow. Measure your room’s dimensions and check if the air purifier is ideal for that room size.

Top Features To Look Out For The Best Air Purifier for Asthma

I have listed the top features you should look for while deciding your pick for the best air purifier for allergies and asthma.

top features to look out for the best air purifier for asthma

1. Auto Mode

The auto mode enables automatic operation. It switches between the fan speeds as per the room’s air quality. Auto mode will do your work for you. Buying an air purifier with this feature will save you time and energy.

2. Wi-Fi Adaptability

Wi-Fi adaptability is essential to remotely control an air cleaner via a smartphone app or voice assistant. In the app, you can access advanced features like monitoring air quality and set schedules.

3. Removable Pre-Filter

A removable pre-filter can be cleaned and reused. If it is not removable, you can only replace it. It will cost you more money. An air cleaner with a removable pre-filter is better.

Pro Tip: Always calculate the filter replacement cost before buying an air purifier. It should not happen that you pay less upfront and spend more on maintenance costs later.

Mistakes To Avoid For The Best Air Purifier For Asthma

  • Be careful while selecting an air purifier. A good air cleaner will make you healthy. But the wrong one can worsen your health condition.
