Why You Need The Best Air Purifier For Allergies

best air purifier for allergies

While you may be aware of pollutants floating around outside, people with allergies may be more vulnerable indoors. That’s why you need the best air purifier for allergies to reduce allergens that could trigger your allergies.

You may think that your home is safe from allergens and pollution. But even though you can’t tell with your naked eye,  indoor air becomes more polluted over time than outdoor air because it’s in an enclosed space. Millions of people around the world suffer from nasal and respiratory allergies. Some people have allergies from dust, cold, pollen, or pet fur. Symptoms can be caused by the air you’re breathing.

This means that if you have allergies, some indoor pollutants may cause you headaches, sore throat and nose, dizziness, or even fatigue. If you continue to breathe in polluted indoor air, it could lead to serious respiratory diseases. Even the pet you love dearly can cause some respiratory problems.

What Is An Allergy?

Allergies occur when your immune system overreacts to harmless substances. If you have an allergy and you come into contact with an allergen, it will cause an allergic reaction. This doesn’t always happen immediately. With time, your immune system builds up a sensitivity to the substance before overreacting and creating antibodies.

Common Allergic Symptoms

When you get an allergic reaction, depending on the type of allergen, it can cause inflammation and irritation. You might confuse some of the signs and symptoms for other conditions. For example, you might have a hay fever allergy, which will cause the same irritations as a common cold. If you’re allergic to pollen and dust, some of the symptoms you will experience include:

  • Running nose
  • Coughing
  • Itchy eyes and nose
  • Swollen and watery eyes
  • Blocked nose

How To Find The Best Air Purifier For Allergies

Minimize exposure

This is the first step you should take to reduce your allergy and asthma reactions. If you have pets, keep them outside or away from your bedroom, off your bed and furniture. Keep your windows closed at home or when traveling in your car. Avoid spending a lot of time outdoors when your allergies are acting up. You can also use air conditioning during the warm months to remove allergens and pollen. Remember to clean the air filters regularly to ensure the filters aren’t clogged with dirt.

Get an air filter

Ventilation is very important when it comes to controlling your allergies caused by pollution. Using an air filter can also help in reducing indoor allergens in your home. Different types of air filters can help you.

Mechanical filters

These trap particles like pet dander, dust mites, pollen, other allergens, and even irritants like tobacco smoke. The most highly effective mechanical filter is the HEPA filter. A true HEPA filter has to be able to capture at least 90% of all the large and microparticles in the air. A true HEPA filter doesn’t recirculate pollutants back into the air once it traps them. Some HEPA type filters in the market don’t meet true HEPA filtration standards, which means you need to be careful when looking for an air purifier with a true HEPA filter. It’s recommended that you replace the filter after 6-8 months so that it can be effective.

Electronic filters

These use electrical charges to attract and trap allergens and other pollutants. Some air purifiers use collecting plates to capture the particles.

Ozone generators

These produce toxic gases that are said to be very effective in removing bacteria, viruses, mold, and other organic pollutants in the air. But these dangerous chemicals can be harmful to your health. Although some air purifiers use ozone to clean the air, prolonged exposure can cause serious health problems. However, if you still want to use an air purifier with ozone, get one that produces very little intentionally or as a byproduct.


This is an important filter in all air purifiers that have a HEPA filter. It helps to capture all the large particles like pet dander and dust and also help to prolong the life of the main HEPA filter. Most pre-filters can be washed and recycled so they can last a long time.

Activated carbon filter

If your home has lingering smells and odors from your cooking, pets, smoke, or chemicals, look for the best air purifier for allergies with an activated carbon filter that will absorb the gases, smoke, and odors in your home.

Ionic filter

Instead of using a fan to suck up the polluted air into the filter, an ionizer uses electricity to produce negatively charges ions that bind with the positively charged airborne particles that become heavy and are captured by the filters or a collection plate. While a HEPA filter can capture all large and small particles, an ionizer significantly reduces the size of the allergens. However, if you have allergies and asthma, it’s advisable to look for an air purifier that doesn’t have an ionizer or one that you can switch on and off. It can trigger your allergies.

UV-C light

Ultraviolet light helps to sterilize and destroy the bacteria, viruses, and germs that are airborne. This C type of UV light isn’t harmful to humans, so if you get the best air purifier for allergies with this feature you should not get worried.
