Combatting Hay Fever with Air Filters: Solutions for a Pollen-Free Home

July 22, 2024Latest blogsBy Naomi Morrow

During the summer, hay fever can cause significant discomfort for sufferers, leading to sore eyes, runny noses, and overall pain. In severe cases, extreme allergic reactions to pollen can result in breathing difficulties, such as asthma attacks. To avoid pollen, many people keep their windows closed during the day. This can increase indoor temperatures and make the season even more uncomfortable.

In the UK, hay fever season spans from late March to September, with different types of pollen peaking at various times. This means individuals sensitive to different pollens may experience fluctuating symptoms throughout the season.

Understanding Pollen and Its Impact

Throughout the summer, the types of pollen in the air change:

– Tree Pollen (March to May): Tree pollen is most prevalent early in the season. As trees blossom in spring, large quantities of pollen are released, affecting about one in four hay fever sufferers, especially in areas with many deciduous trees, such as old-growth woodlands and large public parks.

– Grass Pollen (June to July): Around 75% of hay fever sufferers are affected by grass pollen. This pollen type peaks during the first two weeks of June and again in the first two weeks of July, though the timing can vary based on weather conditions.

Reducing Pollen Exposure Indoors

During hay fever season, it’s nearly impossible to avoid pollen exposure outdoors, and most sufferers rely on antihistamines to manage their allergies. However, it is possible to reduce indoor pollen concentrations and find some relief.

While keeping windows and doors closed can help reduce the amount of pollen entering your home, it can also lead to stuffy and uncomfortable air on hot days, increasing humidity levels and potentially causing condensation issues.

Benefits of Positive Input Ventilation Systems

Positive Input Ventilation (PIV) systems, like Brookvent’s Airplus PIV, are highly effective in reducing indoor pollen levels during hay fever season. These systems maintain fresh air circulation while keeping humidity levels low.

PIV systems draw air into the home through a central unit installed in the loft. This air is then filtered to remove particulate matter, including pollen and other pollutants, ensuring the incoming air is fresh and clean.

A key advantage of whole-house PIV systems is the creation of slightly higher air pressure inside the home. This positive air pressure helps minimize the entry of unfiltered air through gaps around windows and doors. Consequently, pollen levels are further reduced, and any pollen that does enter the home is pushed out along with excess humidity, thanks to the higher-pressure air.
