Clean Air Day: Have you checked your ventilation filters?

no comments

Vent-Axia is urging households to check their ventilation filters for Clean Air Day as part of a big push on improving indoor air quality.

Clean Air Day is coordinated by environmental charity Global Action Plan and aims to raise awareness of the risks of air pollution and the simple things everyone can do to improve their air quality and health.

One simple thing households can do to help improve indoor air quality and their health is to check whether the air filters in their ventilation systems need cleaning or changing.

Why should you check your filter?

Many households in new build properties may be unaware that their whole house ventilation systems, such as mechanical ventilation with heat recovery (MVHR), have filters that need to be checked every three or six months, cleaned regularly and replaced twice a year.

The purpose of an MVHR filter is to filter out microscopic particles like PM2.5 (including fine diesel particulates) dust and pollen so they are not brought into the home from outside.

However, a dirty blocked filter can recirculate these particles into the home adversely affecting indoor air quality (IAQ). Dirty filters can also affect the efficiency of the ventilation system which affects its effectiveness.

How bad is poor IAQ?

Jenny Smith, Head of Marketing at Vent-Axia, says poor IAQ is reponsible for around 99,000 deaths in Europe each year – one every six minutes.

A government paper published in October 2018 reported that poor IAQ costs the UK over 204,000 healthy life years, with 45% of those lost to cardiovascular diseases, 23% to asthma and allergy and 15% to lung cancer.

Jenny said:  “We are pleased to support Clean Air Day as it continues to raise awareness of the importance of clean air, particularly indoor air quality, and how everyone can make changes to improve their IAQ and their health.

“To help improve indoor air quality, this year for Clean Air Day we are encouraging households to check their ventilation filters. It is very simple to check and change a filter only taking a couple of minutes but it will help improve air quality in the home and help your ventilation run more efficiently.”

The purpose of Clean Air Day is to increase understanding of the risks and educate everyone on how to reduce air pollution and improve IAQ. In the past, the focus was on outdoor air pollution, but Clean Air Day aims to highlight the devastating health impacts of poor IAQ too.

A staggering 65% of homes in the UK suffer from poor IAQ as a result of inadequate ventilation. Poor air quality is proven to negatively impact on everyone’s health, increasing the risk of serious illnesses and making existing conditions, like respiratory disorders, worse.


To help protect health in the home, Vent-Axia has been working hard to provide ventilation solutions to improve IAQ for households. For new build homes, Vent-Axia’s Sentinel Kinetic mechanical ventilation with heat recovery (MVHR) system boasts an impressive 94% heat recovery. A vital part of an MVHR system is its filters.

Inside an MVHR unit, fresh incoming air passes through a filter to remove pollen, debris and products of pollution.

Filters up to ISO ePM2.5 70% (F7 grade) ensure even homes in heavily urbanised areas can filter out most impurities, up to and including PM2.5 particles, for example diesel particulates. To ensure MVHR systems run efficiently and effectively Vent-Axia also offers ventilation servicing to maintain the systems and check and replace filters as needed.

For private refurbishments, Vent-Axia’s new PureAir Sense is equipped with a pioneering odour sensor that increases airflow when the air is poor, helping ensure a comfortable living environment. Meanwhile, the Lo-Carbon Revive has been designed specifically with social housing in mind offering an effective continuous ventilation solution for residents.

As well as urging households to check their filters for Clean Air Day, Vent-Axia is also supporting the initiative by asking its staff to leave their cars at home today to help reduce air pollution on the day.
