An air purifier or air cleaner is a device which removes contaminants from the air in a room. These devices are commonly marketed as being beneficial to allergy sufferers and asthmatics, and at reducing or eliminating second-hand tobacco smoke. The commercially graded air purifiers are manufactured as either small stand-alone units or larger units that can be affixed to an air handler unit (AHU) or to an HVAC unit found in the medical, industrial, and commercial industries. Air purifiers may also be used in industry to remove impurities such as CO2 from air before processing. Pressure swing adsorbers or other adsorption techniques are typically used for this.

Why Invest in Better Home Air Quality?
Air quality is about more than just being comfortable. Health Canada says that Canadians spend about 90% of our time indoors. Now that we’re insulating our homes better these days, it can mean that our indoor air pollution is worse than the air pollution outside.
Sources of indoor air pollution can include:
- Gasses from improperly maintained heating equipment
- VOCs (volatile organic compounds) and semi-VOCs in building materials and furniture
- Dust and dust mites
- Pet hair and dander
- Molds and mildew
- Tobacco smoke, including second-hand smoke (sometimes a problem for townhouse/condo residents with imperfect seals between homes)
- Plus any outdoor air pollution that enters your home, especially in a big city like Toronto.
These can contribute to health issues like asthma and allergies.
There are two basic types of air quality systems: air purification/filtration and humidity control systems.
Air Filtration and Purification
The goal of air filtration and purification is to remove harmful gasses and particles from the air. Physical filters, including HEPA filters, are designed to trap microbes and dust mites that are so small we don’t even know they’re there. The furnace filters you can buy in the hardware store will only trap particles of a certain size – generally 10% of the particles, viruses and spores that are floating around your home.
Air filtration systems are all assigned a MERV (minimum efficiency reporting value) rating. The higher the MERV number, the more types of particles it can trap because it can trap smaller particles. MERV values range from 1 – 20. You can see a chart of what the different MERV values typically do here.
Maintaining the proper level of humidity in our homes can be challenging. In winter, our heating systems tend to dry the air too much, and in summer there can be too much humidity trapped indoors.
Lack of humidity in winter can cause wood flooring and furniture to warp, and to increased colds and sore throats. It also causes some people to turn the heat up higher, because dry air can feel colder. Too much humidity increases the risk of a mold or mildew problem developing. In some homes, inadequate ventilation or moisture proofing is the issue, but sometimes it is a matter of proper control of the humidity level in the air.
