Air Filter Sales Near Ottawa

When it comes to maintaining your furnace, a clean air filter is the first place to start. Your air filter is designed to filter dust, allergens, and other particles out of the air.

When your air filter becomes clogged with various particles, it reduces airflow to the furnace, causing the furnace to work harder and reduces air circulation throughout your home. A dirty filter can also release trapped allergens and other particles into your HVAC system, which may cause further issues down the road.

Help Finding the Right Filter

It’s important to always use the correct quality and size air filter for your system. In some cases the air filter box may require a non-standard size filter. Although a standard size filter may fit in these boxes, they will leave gaps where dust, debris, allergens, and bacteria can bypass the filter and contaminate the furnace and ductwork. A proper fitting air filter will help extend the life expectancy of your furnace and provide better air quality for your home.

Dirty vs. Clean Air Filter

Importance of the MERV Rating

Filter quality plays a big role when it comes to air circulation and the reduction of dust or allergens in your home. All air filters come with a MERV rating (Minimum Efficiency Reporting Value). The MERV rating was designed in 1987 by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) to help evaluate the effectiveness of HVAC air filters. ASHRAE has found that filters with a MERV rating of 7 to 13 are almost as effective as a true HEPA filter in residential applications.

There are two basic styles of air filter: Fiberglass and Pleated

Fiberglass filters are usually white or blue and are transparent. These filters have a very low MERV rating (Between 1 and 4) and are best suited for temporary use, such as during renovations.

A pleated filter captures dust and allergens that a fiberglass filter won’t, and they carry a much higher MERV value. As such, these filters are best suited for regular use in your home.

Dr. Duct BBB Business Review

See 5-star Reviews From Customers Like You

I had great experience with these guys. Came on time, put a lot of effort and attention to detail. Their price was 30% cheaper than their competitors (they had a promo at that time). As it turned out a lot of the HVAC companies in Ottawa re-sell third party duct cleaning services..


Great work Dr Duct! We appreciated your thoroughness and attention to the smaller details that guarantee a first-class job! This year, thanks to your fine work, we can say that as far as our home is concerned Spring really did arrive early.

Third time that I have used Dr. Duct. I am very happy with the results. Excellent service. Great team of workers.


The guys were very professional, great job, I was even able to watch it all on the screen. That was a eye opener. Would definitely recommend them.


The guys arrived on time and did an excellent job. They invited us to watch the monitor as they were cleaning the ductwork. Very professional. Will hire them again.


I am well pleased with the services I received with Dr. Duct. These guys did a great job replacing my dryer piping and repairing a rattling air duct. Very reasonable prices too.


I highly recommend Dr. Duct. I shopped around and they gave the best estimate. They arrived as scheduled, did a great job, cleaned up and the price was as originally quoted. They were extremely professional and cheerful.
