In September 2026 AprilAire announced TriPure, a new filter technology that now ships in its next-generation air filters. AprilAire says the filters capture more dust, pollen and lint, let air move more freely through your system, and last longer between changes. Here is what the company is claiming, how the filter sizes map to the equipment in your home, and what we would check before you switch.
What AprilAire Announced
AprilAire introduced TriPure Technology on September 3, 2026. It appears in new AprilAire filters in two sizes, and the company makes three headline claims about them.
Claim 1
More capture
AprilAire says TriPure filters catch more pollen, household dust and lint than leading brands, based on its own testing to the ASHRAE 52.2 (2017) standard.
Claim 2
Easier airflow
AprilAire says airflow is up to 20 to 30 percent better than leading brands because the filter creates less resistance. Less resistance means less strain on the blower.
Claim 3
Longer life
Filter life is listed as up to 6 months for the 1-inch size and up to 12 months for the 3-inch size, depending on the model.
These are manufacturer claims from AprilAire’s own testing, and results vary with the equipment and the home. We are passing them along as AprilAire’s, not as something we have measured.
Which Size Goes Where
The filter size follows the equipment it goes into. The two are not interchangeable.
| Filter size | Where it goes | What it does |
|---|---|---|
| 1-inch | The filter slot in your furnace or air handler | Standard system filter for homes without a whole-house air purifier |
| 3-inch | A high-efficiency AprilAire whole-house air purifier | Replaceable media inside the purifier cabinet, typically changed about once a year |
AprilAire also offers odor-reduction filters with activated carbon and MERV 16 filters aimed at allergy and asthma triggers. Which one fits depends on the exact model of your purifier, so check the model number before you order. If you are not sure what you have, we can read it off the cabinet during a visit to your AprilAire air purifier.
Is Switching Worth It?
It depends on what is in your house today.
- You have an AprilAire purifier with a 3-inch filter: the next filter change is the natural time to ask about the new media. AprilAire has also described a one-time upgrade rail that helps new 3-inch filters fit existing purifier cabinets.
- You use a basic 1-inch filter in your furnace: a better filter helps, but a higher rating alone is not the goal. A filter that restricts airflow makes the blower work harder, which is exactly what AprilAire says TriPure reduces. Ask for the airflow numbers, not just the MERV rating.
- You have allergies or pets: the right filter is the one your system can move air through. We would rather match the filter to the blower than chase the highest number on the box.
- Your system is already struggling: weak airflow, a frozen coil or a blower that runs hot is a service issue. A new filter will not fix it.

How We Handle Filter Changes
Filters are a service item, and we check them on every visit. Our semi-annual maintenance plan includes a spring and fall visit where the filter, blower and coils get a look, so a dirty filter does not turn into a repair. If you have an AprilAire purifier or humidifier, we can service the whole indoor air system in the same visit.
When you do replace a filter yourself, turn the system off, bag the old filter without shaking it, and install the new one with the airflow arrow pointing toward the furnace or air handler.
Not Sure What Filter Your System Takes?
Send us a photo of the filter or purifier label, or book a visit and we will confirm the size, rating and replacement schedule. Ask for a quote or call us.

TriPure is AprilAire’s new filter technology, announced on September 3, 2026, and used in its next-generation 1-inch and 3-inch air filters. AprilAire says it captures more particles, restricts airflow less and lasts longer than leading brands.

Use a 1-inch filter in the furnace or air handler filter slot, and a 3-inch filter in a high-efficiency AprilAire whole-house air purifier. Confirm your purifier model number before ordering.
Are AprilAire’s performance claims independently verified?
The comparisons come from AprilAire’s own testing to the ASHRAE 52.2 (2017) standard against unnamed leading brands. Results vary with the equipment and the home.
