Pollen Allergies And How Coway’s Airmega Air Purifiers Improve The Air You Breathe

Jul 03, 2025
Coway UK


Allergy UK reports that around 26% of adults and 10-15% of children in the UK suffer from Allergic Rhinitis, what most people call “hay fever”, caused by pollen. However, it’s not all bad news. There are things you can do to alleviate symptoms or even prevent them. 

Let’s explore what you can do and how Coway air purifiers filter out pollen that might cause an allergic reaction. 

Pollen: The Tiny Trouble Maker

Pollen released by plants is an allergen. It causes sneezing, coughing and itchy eyes. When pollen is in the air, it’s hard to escape.

What Are Pollen Allergies?

Pollen allergies occur when your body overreacts to pollen. This reaction causes allergy symptoms, we commonly refer to these as “hay fever”.

Types of Pollen

There are three types of pollen:

  • Tree pollen: Released in early spring.
  • Grass pollen: Released in late spring and summer.
  • Weed pollen: Released in late summer and autumn.

Knowing what type of pollen bothers you helps you manage your allergies.

What Causes Pollen Allergy?

Pollen allergy is caused by the immune system’s overreaction to pollen. When pollen enters the body, the immune system mistakes it as a threat and releases histamine and other inflammatory chemicals. This immune response is what causes the classic allergy symptoms that make sufferers feel miserable.

How To Avoid Pollen

You can’t avoid pollen completely but you can minimise your exposure by:

  • Staying indoors on high pollen days.
  • Wearing a mask when outdoors.
  • Taking a shower after being outdoors.
  • Using an air purifier.

What Are The Symptoms of Pollen Allergy?

Symptoms of pollen allergy vary from person to person but common symptoms are:

  • Sneezing
  • Runny nose
  • Itchy eyes
  • Watery eyes
  • Nasal congestion
  • Post-nasal drip
  • Coughing
  • Wheezing
  • Fatigue
  • Difficulty sleeping

When To See A Doctor About Pollen Allergy

If you have pollen allergy symptoms, see a doctor to get diagnosed and discuss treatment options.

What are the treatment options for pollen allergy?

There are:

  • Over-the-counter medications such as antihistamines and decongestants
  • Prescription medications such as nasal corticosteroids
  • Allergy shots

How Coway Helps You Combat Pollen

Airmega: Your Pollen Fighter

Coway’s Airmega air purifiers can reduce pollen exposure indoors. They have advanced filters that capture pollen and other allergens.

How Airmega Works

  • Pre-filter: Catches larger particles.
  • Activated carbon filter: Removes gases and odours.
  • True HEPA filter: Captures 99.97% of tiny particles, including pollen.

Airmega For Different Room Sizes

We have Airmega models for all room sizes, so you can find the right one for your space. From compact units like Airmega 100 for small bedrooms to large capacity models like Airmega 300 for open-plan living areas, there’s an Airmega purifier for you.

These purifiers have impressive coverage, removing pollen and other allergens from every nook and corner of your home, making it cleaner and healthier indoors.

Coverage Area

Each purifier has a different coverage area and Clean Air Delivery Rate (CADR) based on its size and capabilities. Here’s a summary:


Model

CADR

Airmega 300

149 m²

575 m³/h

Airmega Mighty

109 m²

421 m³/h

Airmega Jet

402 m³/h

Airmega 150

73 m²

281 m³/h

Airmega 100

63 m²

240 m³/h

Airmega Aim

34 m²

132 m³/h


Smart Automation For Pollen Protection

To combat pollen, air purifiers need more than just filtration; they need smart features that boost their performance. Features like auto mode, air quality monitoring and filter replacement indicators make it easier to have a pollen-free home.

For example, auto mode adjusts the fan speed based on real-time air quality, so the purifier works efficiently to remove pollen and other pollutants. 

The air quality monitoring system lets you check the air quality in your home and respond accordingly.

And, the filter replacement indicator lets you know when to change filters at the right time to keep your Airmega purifier running optimally.

How To Improve Indoor Air Quality In My Home?

In addition to using an air purifier, you can also:

  • Keep your home clean and free of dust and pet dander.
  • Open your windows to let fresh air in.
  • Use houseplants to purify the air.
  • Avoid using harsh chemicals.

By taking these steps, you can help reduce your exposure to pollen and other allergens and improve your overall health and well-being.

Breathe Easy With Airmega

Airmega can help you have a healthier indoor and reduce allergy symptoms.
