MINT is a special air exchanger that is designed with a vintage appeal, painstakingly crafted, and packaged in an attractive cabinet enclosure.


The portable air exchanger market is filled with so-called "portable" units that require permanent installation. We fill this gap by manufacturing truly portable and attractive products.


Most air exchangers are installed by contractors who tear down houses or drill into walls. However, our products can be easily installed by anyone without technical background!


Our air exchangers are built by hand in our small factory. While this represents significant manufacturing costs, our products are less expensive than what is offered by competitors.

Heat Exchanger

The technology of the heat exchangers in ventilation systems has largely remained stagnant since the 1970s. However, MINT uses a novel patent-pending shell-and-tube heat exchanger for passive heating in the winter and passive cooling in the summer. There are no electrical heating elements or refrigerant cooling coils in the unit. The heat exchanger is mechanically robust and can prevent frost buildup even in extremely cold climates.


MINT consists of two inline fans. A mixed-flow fan is used to supply fresh air to the indoor space whereas an axial fan is used to exhaust air to the outdoors.





By default, MINT uses MERV4 filters to extract large airborne particles of up to 10 microns from the outdoor air that is supplied to your space.

No. Our air exchangers are calibrated for balanced flow of air through the supply and exhaust vents during manufacturing.

No. Our air exchangers are designed to operate independently of any external appliances.

No. Our portable air exchanger is designed for direct venting to the outdoors: through a door / window / wall.

Yes. We provide 10 ft. of ventilation duct for free with every ordered air exchanger.

No. We are unable to supply ventilation kits due to the wide variety of windows and doors that are used by our customers. However, we can recommend appropriate kits.

To the best of our knowledge, most spaces will not need a condensate kit. Accumulated buildup of moisture is unlikely given the operating flow rate of the air exchanger.

Yes, we provide warranty on the main parts of the air exchanger.
