HEPA Filter Installation in Ottawa

Just Air installs whole-home HEPA and high-efficiency filtration for houses across Ottawa, matching the filter media and static pressure to your existing furnace and blower so it actually fits your system. Most installs are finished in a few hours. Call (613) 266-9742 to book an assessment.

True HEPA filtration and high-MERV filtration solve the same problem in different ways, and picking the right one starts with your furnace’s blower, not the filter itself. A true HEPA filter is dense enough to catch very fine particles, but that density creates real resistance to airflow, more than most residential blowers are built to push through directly. That is why true whole-home HEPA is usually installed as a bypass unit: a sealed cabinet with its own smaller blower, plumbed in parallel to your main ductwork, so it filters a portion of the air constantly without choking the main system. A high-MERV filter, by contrast, drops straight into your existing filter slot or a media cabinet and catches most of what people care about, including dust, pollen and pet dander, without the static pressure penalty.

We will say this plainly: a true HEPA bypass unit is not the right call for every house. If your ductwork is undersized, your blower is already working hard, or your main concern is everyday dust and allergens rather than a specific medical need, a well-chosen high-MERV media filter usually gets you most of the benefit for a lot less complexity. We check your existing duct static pressure and blower capacity before recommending either option.

Installing a high-MERV media cabinet is usually a two to three hour job. A true HEPA bypass system takes longer, typically most of a day, because it needs its own duct taps, a dedicated blower, and sometimes an electrical connection.

Cost is moved mainly by which type you choose, how much duct modification the bypass cabinet needs, and whether your electrical panel can take another small circuit without an upgrade. There is no gas work involved in a filtration install, so TSSA registration does not apply here, but we still handle any electrical permit or inspection the job calls for.

Before we come out, it helps to know why you are looking at filtration. Ongoing allergies, a new baby in the house, or just wanting cleaner air day to day all point toward different equipment. HEPA and high-MERV filtration is one piece of a broader indoor air quality plan that often starts with duct cleaning. We install filtration systems across Ottawa and the surrounding areas, and financing is available for larger jobs through our financing page.
