Furnace filters are designed to trap dust and airborne particles as the air is drawn through the filters into the furnace system. A clean furnace filter makes a big difference in the air quality within the home or business and can also help reduce energy costs by allowing the furnace system to function efficiently and effectively.

 

It is recommended to regularly check the filters to make sure they are in good condition and performing as they should be. Being aware of the condition the filters are in will keep your furnace operating safely.

 

Furnace filters, after time, will inevitably get clogged up by the accumulation of black, yellow, or

brown deposits which are waste products from the combustion of heat within the system itself.

The build-up that occurs on furnace filters will vary from house to house and of course where it is you reside.

 

As most Langley residents are aware, the air quality in the area is far from perfect. This undoubtedly results in the likelihood of furnace filters becoming obstructed and polluted in a much shorter amount of time, which results in filter change-outs more often.

 

Although there is a general ‘rule of thumb’ to change out filters every 90 days or so, this may not be the ideal recommendation for all furnace systems due to location and air quality and may result in the need for filter change-outs much more often.

 

There are many contributing factors when it comes to furnace filters becoming obstructed from doing their intended purpose. A clogged furnace filter not only impacts the quality of air being circulated through the system but also has an impact on the life of your furnace by having air needing to be forced through dirty filters which make your furnace work overtime.

 

Depending on where you live will determine how often these filters need to be changed out.

Environmental factors such as smog from the city life, dust and debris from farms and construction sites, industrial and factory pollutants, and pets that reside in the home all contribute to the timeline of when and how often your filters will need to be swapped out.

 

Furnace filters range and are scaled on a MERV (Minimum efficiency reporting value) rating system. MERV ratings range from 1-16. The higher the MERV rating on the filter, the fewer dust particles, dust mites, pollen, bacteria, tobacco, mould spores, and other contaminants can pass through it.

 

Filters with ratings from 6-12 are typically used in residential furnaces as filters rated below 6 may not adequately block airborne particles. Filters with a higher rating of 12 and higher are designed for specialized use, such as hospitals.

 

Manufacturers recommend filters rated 6 through 9 should be changed every 90 days while those with a rating of 10-12 should be changed every 60 days.

So, what happens if you decide not to change out those dirty and polluted furnace filters?

 

System shut down or fire

Dirty filters cause potential safety concerns due to the high possibility of overheating the system which may result in the system overheating and shutting down or worst-case scenario, starting a fire.

 

Air Quality

Having air run through a dirty filter can increase, rather than reduce, allergens, and have your system circulating unwanted pollutants back into your home, causing adverse reactions to anyone within the home or business.

 

Reduced lifespan of your HVAC unit

By not changing out filters regularly will result in your furnace system having to work overtime by reducing airflow and have your furnace pushing harder to keep up. The harder your furnace works; the quicker parts will wear out and need replacing.

 

Higher energy costs

Due to your furnace working harder and longer by having clogged filters will result in using more energy and hiking up your energy costs, especially in wintertime and during times when your furnace is in high demand.

 

Typically, your furnaces owner’s manual will specify the best MERV rating for your furnace however, if you are unable to locate the manual or unsure of the best MERV rating filter that should be used in your home or business, Valleyshore Plumbing & Heating in Langley can assist in helping determine which filters are best suited for your furnace system while taking into consideration of the environmental factors and seasons.
