Pollen – Affecting Human And HVAC Health



A staggering 44 per cent of British adults suffer from at least one allergy and the number of sufferers is on the rise. One of the most common reactions is allergic rhinitis (aka hay fever), which is often caused by airborne pollen, and affects between 10 and 30 per cent of adults and up to 40 per cent of children.

Runny and blocked noses, sneezing, itchy eyes, headache, earache, reduced concentration… all are symptoms of hay fever.

But the release of histamine caused by hay fever can also exacerbate the symptoms of asthma which hospitalises someone in the UK every eight minutes; 185 people are admitted to hospital because of asthma attacks every day. Typical allergic asthma symptoms include wheezing, coughing, chest tightness and difficulty in breathing.

Allergic asthma and hay fever can also contribute to other serious health complications. One such is anaphylaxis which may, for example, cause problems such as an abnormal heart rate, weakness, low blood pressure, rapid pulse, cardiac arrest, and pulmonary arrest. If left untreated, anaphylactic shock can be life-threatening.

Pollen is a botanical term first used as long ago as 1760. It refers to the fertilising element of flowers and, nowadays, is widely recognised as fine, powdery, yellowish grains or spores.

The pollen season occurs when plants and trees have flowers. Countering the health effects of pollen and other airborne allergens involves several steps, but the simplest is to prevent them from entering a building space in the first place.

ECEX Air Intake Screens are designed with precisely this aim in mind. These long lasting, weather resistant filters are designed specifically for high velocity airflow applications such as chillers, dry air coolers, air handling units, cooling towers and air conditioning units.

They prevent airborne debris – including pollen – from clogging internal coil fins, perishable filters and other components.

But their benefits don’t end there. ECEX Air Intake Screens also boost energy performance, reduce maintenance time by up to 70%, extend service life of equipment, prolong the life of internal air filters by up to 60%, and radically cut the risk of breakdown and downtime.

Lasting up to 15 years and cleaned simply using a soft brush, hose or vacuum, ECEX Air Intake Screens are the ideal first line of defence for air intake systems.
