For Hayfever sufferers, pollen from grass and flowers can make summer a miserable time with painful allergy symptoms preventing them enjoying the weather.

Without good airflow pollen levels can build up over time along with other allergens and cause painful allergic reactions.

During hay fever season, streaming eyes and sore throats are daily problems, and it can seem like there’s no escape even if you stay indoors to avoid pollen.

Improved ventilation in your home will help to reduce the concentration of pollen that can trigger hay fever, but opening a window simply allows more to enter the building

Around 10 million people in the UK suffer from Hay Fever, and unlike most people who look forward to spring and summer, people with hay fever face several months of misery as they battle with a severe allergic reaction to pollen

Many respiratory illnesses including asthma, allergies, and hay fever can be triggered by allergens in the home including mould spores, and house dust mites.

According to the National Pollen Research Unit, air pollution in towns could cause the number of people with Hay Fever in the UK to double by 2040.

Hay fever is believed to affect over 10 million people in the UK and can be an annual visitor or afflict people for a shorter time. It is an allergy caused by pollen or dust which inflames the mucous membranes of the eyes and nose, causing a runny nose and watery eyes.

Research by the Royal College of General Practitioners revealed a 114 per cent increase in people visiting their GP with hay fever symptoms in 2014, as more people took action against the seasonal condition. It is therefore hardly surprising that EnviroVent has seen a rise in sales of its ventilation systems that may help to relieve the symptoms of hay fever and other allergies.
