Do Air Purifiers help with Allergies?

Symptoms of allergy may be exacerbated by poor indoor air quality. For people living with allergy, the main concerns are the impact of poor ventilation and high humidity on house dust mites and mould growth, increased airborne contaminants caused by products used around the home, allergens from animals and plants in the home. Allergens such as mould spores, house dust mites and pet dander are commonplace indoors, causing severe symptoms for those who react to these specific allergens.

One way to improve indoor air quality is by “Running an air purifier continually as per the manufacturer’s instructions can assist in the reduction/removal of airborne allergens such as house dust mite, mould spores, dander, VOC’s and smoke”.  Your Quick Guide to Indoor Air Quality by Allergy UK 

Do Air Purifiers help with Asthma?

“As Ireland has a cold, damp climate, we tend to spend a significant amount of time indoors. It is for this reason that research into indoor air quality is vital, especially for people with chronic respiratory issues such as asthma.”

Asthma Society of Ireland

Asthma Society of Ireland conducted a 3 month review of air quality in the home before and after the use of Air Purifiers. The study also highlighted to role of particulate matter in increasing the frequency of asthma symptom. “This not only highlights the value of indoor air monitoring in tracking and identifying asthma triggers but also indicates a potential role for air purification as part of ongoing asthma management”.

H13 True HEPA Air Purifiers are designed to remove particulate matter (PM) from the air as small as PM 2.5.

How to choose your Air Purifier?

When researching air purifier units, it is essential that you choose a unit that can fully clean all of the air within the room.  This is referred to as ACH (Air changes per Hour). To select the correct unit for your room, you will need to calculate the volume of your room.

Most air cleaners are labelled with a rate for CADR (Clean Air Delivery Rate). You can calculate the air changes per hour by using the below equation.

Depending on the size of the room you may require more than one air purifier to meet the requirements set out by the Department of Education – Three Air Changes Per Hour.

Once you have found a unit that is suitable for your requirements, it is a good idea to check the life span of the filters within the Air Purifier and that the filters are readily available.
