Allergy Proof Your HVAC System
It’s a beautiful sunny spring day and It would be a perfect day if you didn’t have nasty allergies. If you’re like 28% of Canadians, spring and fall can unleash a variety of symptoms including runny eyes and noses, sneezing and even wheezing. While we can’t control the allergens we come in contact with when we’re outdoors, but we can take steps to allergy proof our HVAC system for when we are indoors.
What are the most common type of indoor allergens? Dust mites, dander, pollen and cockroach droppings are the most common irritants. Although your HVAC system should be filtering these out of the air, if it is not running efficiently, it may be blowing these throughout your home.
Clean air is important
Mold and Mildew can hide in your HVAC sstem
Bacteria can invade your system
Check the level of humidity in your home
When you have your HVAC system inspected, the technician should also inspect the humidity level, which should be no higher than 40%. Humid air can cause mold, mildew and other allergens to multiply.
If necessary, you can install a dehumidifier to lower the humidity. A ventilating whole house dehumidifier brings in filtered fresh air and removes humidity. Devices with a fresh air intake will also push fresh outdoor air into your living space.
Dirty Filters can make your allergies worse
HVAC filters are designed to keep debris from contaminating your air. You should replace your filter every 2 to 3 months. Make sure the filter fits into the housing properly. Otherwise the air bypasses the filter and is not cleaned properly.
A couple of more efficient filter options are media filters and HEPA filters. Media filters are larger than standard 1” filters, so the larger surface catches more particles. They only need to be replaced once or twice a year. There are regular and carbon coated media filters which provide even better filtration.
The best type of filter is a HEPA filter. Why are HEPA filters better? They filter out 99.97 percent of contaminants!
How do you know which one to choose? Filters have MERV ratings from 1 to 20 which rate the air quality. Pick a filter with a MERV rating from 10 to 20 and you will breathe easier.
Open windows are not your friend
Are your ducts leaking
Old HVAC systems may not be doing a great job for you
If it’s time for a new system, newer variable speed and two speed HVAC systems will provide cleaner air. They operate at a lower speed which helps remove the humidity which helps dust mites and other microbes grow.
