HEPA & active carbon filtration purify up to 99.97% of allergens, viruses, and bacteria down to .3 microns, while reducing odors and fumes.

Cost Effective Solution

Long-lasting, replaceable filters provide superior value & performance when up against comparable standalone room purifiers.

Set It & Forget It

Compact and durable design is easy to install with no additional electricity needed & can run up to 6 months of continuous use.

Inside Air

Inside air can be up to 5 times as polluted as outdoor air.

Outside Air

PTAC units introduce up to 35% of the outside air into the area that it's heating and cooling.

RZ Testing

PTAC units naturally get dirty and can be cleaned on a regular basis. During the in-between there is RZ AIRflow protecting you from the unseen!


The RZ AIRflow works with your PTAC unit to improve your air quality wherever you are. With its portable design and simple installation, the RZ AIRflow gives you clean, purified air at home or on the go.
