The Only HEPA Filter Engineered for Every PTAC Unit
Most HEPA filters are built for standalone air purifiers. The RZ AIRflow HEPA Replacement Filter is different — it's the only HEPA filter specifically designed to fit all standard PTAC heating and cooling units, turning your existing HVAC infrastructure into a hospital-grade air purification system.
RZ Mask has been engineering precision respiratory and air filtration products since 2011, with 15+ USA and international patents. The AIRflow filter line brings that same exacting standard to commercial indoor air quality.
What Does 99.97% Filtration Actually Mean?
True HEPA filtration captures 99.97% of airborne particles down to 0.3 microns — that includes dust, dust mites, pollen, mold spores, bacteria, and viruses. For context, a human hair is ~70 microns wide. These filters capture particles 233x smaller.

How long do RZ filters last?
The life expectancy of your RZ Filter depends on many variables, such as; particulate exposure density, particulate exposure duration, and user breathing rate.
Ultimately, filter life depends on your environment. Replace your filter when breathing becomes noticeably harder, the filter looks dirty, or after heavy-dust days.
What kinds of particles do RZ Masks help protect against?
RZ Masks are designed to help reduce exposure to airborne particulates like dust, pollen, smoke, and other jobsite or everyday nuisance particles. Different models/filters have different performance levels, so check the product’s certification or filter spec for exact use-cases.
