Indoor air quality has become a growing concern over recent years as research estimates that our air quality is up to five times worse inside our homes than out.

From chemicals in cleaning products and hair sprays to dust, pollen and pet dander, our home environments probably aren’t as healthy as they could be. On average, we spend more than 90% of our time indoors, so choosing the right products to help achieve clean, fresh and healthy air is essential.

Leading ventilation specialist, Glen Dimplex Heating & Ventilation, which includes the Xpelair and Dimplex brands, has just the ticket to improve the quality of air in your home, combating the daily misery of allergens and common irritants, such as pollen and dust, with its range of air purifiers.

Ideal for use in the bedroom, living spaces and children’s bedrooms, these quiet, sleekly designed air purifiers remove contaminants that build up, leaving cleaner, fresher indoor air. Particularly good news for those prone to allergies and asthma, especially during hay fever season.

Did you know?

  • Indoor air can contain more than 900 chemicals, particles and biological materials with potential health effects, and can be up to 50 times more polluted than outdoor air

  • 58% of people have experienced mould or condensation in their homes
  • Over 98% of indoor particles are invisible to the human eye. Our eyes can see particles above 40 microns in size, but bacteria can be as small as 0.05 micron and noxious gases as small as 0.001 microns
  • 39% of asthma cases in children could be prevented by reducing trigger sources in the home*
  • A staggering 44% of British adults now suffer from at least one allergy and the number of sufferers is on the rise, growing by around 2 million between 2008 and 2009 alone. Almost half (48%) of sufferers have more than one allergy**

Nick Paul, Portable Product Manager at Glen Dimplex Heating & Ventilation, provides some expert advice on how to freshen the air in your home…

Q: Why should we be concerned about the quality of the air in our home?

A: Radical changes in design and construction methods of domestic buildings over the past two decades mean that our homes are better sealed and insulated. While they might be warmer and more energy efficient, they are unable to breathe naturally. This lack of ventilation means that the level of pollutants in our indoor air often exceeds those found in outdoor air.

An independent indoor air quality study looked at the concentration of total volatile organic compounds (TVOC) – that is allergens, irritants and toxic substances – in more than 120 UK homes. It found that only 9% of homes fell into the ‘normal’ bracket, with the remaining 91% above the recommended TVOC concentrations.

Q: What causes these high levels of VOCs?

A: High levels of VOCs can be caused by everyday objects and activity. Cooking and heating appliances, paints, solvents, carpets, cleaning products, toiletries and even our pets, all release VOCs into the air. On top of this, outdoor contaminants from traffic and industry can enter homes through open windows and doors. Exposure to this potent mix of airborne particles in the home is being termed ‘Toxic Home Syndrome,’ with an estimated 15.3 million homes in the UK believed to be at risk of this. We spend more than 90% of our time indoors, so there is a very real need to take action.

Q: Why do you need an air purifier?

Deciding why you need an air purifier will help narrow down the type of technologies that you will need. If someone in your home has allergies, then choose a purifier that features a HEPA filter, or if you’re looking for an easy way to neutralise cooking smells in your kitchen, a purifier with carbon filtration is ideal. For all-around use then look for a model that features a combination of filtration stages – the more stages of filtration, the cleaner the air will be. 

Q: What does an air purifier do?

A: Air purifiers draw in air from the room and filter it to release fresher, cleaner air, helping to eliminate the pollen, dust and other particles that make us cough and sneeze. This makes them a must-have for allergy, asthma and hay fever sufferers.

Q: How does it work?

A: Air purifiers use a fan to pull in dirty air at one end, remove pollutants, and output clean air at the other end. As air passes through the air purifier, the HEPA filter traps 99.5% finer particles, including pollen, dust mites, mould spores and pet dander, and the ultra violet-C (UVC) filter removes 99% of viruses and germs. A carbon filter then ensures any unwanted odours and toxic fumes are reduced. Finally, an Ioniser removes airborne allergens and enhances immunity.

Q: What size air purifier do you need?

A: Different purifiers can be used for different sized rooms, so make sure that you pick a model that will best suit the room dimensions it will be used in. It is also worth considering whether you want your purifier to be standing on the floor or ‘table-top’ style, depending on where in the room you decide to use it. The weight and physical dimensions should also be thought about if you intend on moving the purifier around the home as needed.
