Clean Air in Every Room — RZ AIRFlow for PTAC Heating & Cooling Units
The RZ AIRFlow is an internationally patent-pending air purifying system engineered specifically for PTAC (Packaged Terminal Air Conditioner) units — the wall-mounted heating and cooling systems found in hotels, senior living facilities, apartments, and extended-stay properties. Where standard PTAC units recirculate unfiltered air, the RZ AIRFlow installs directly into the unit and delivers True HEPA 99.97% filtration of airborne particulates down to 0.3 microns, combined with an active carbon layer that eliminates odors and VOCs.
Built by RZ Mask — the company behind 3+ million respiratory protection products sold worldwide since 2011 — the RZ AIRFlow applies the same filtration engineering that defines the RZ Mask lineup to the spaces where people sleep, recover, and live.
Key Features
- True HEPA Filtration — 99.97% at 0.3 microns: captures dust, dust mites, pollen, mold spores, and fine particles
- Active Carbon Layer — Eliminates odors, smoke, and VOCs from recirculated air
- Fits All Standard PTAC Units — Universal design, no tools required for installation
- Internationally Patent-Pending — Purpose-built for PTAC environments
- Lightweight & Durable — Built for long-term, continuous use
- Replaceable Filters — HEPA and active carbon replacement filters available separately
Who Is the RZ AIRFlow For?
The RZ AIRFlow is designed for property managers, hotel operators, senior living facilities, apartment managers, and individual guests who want to upgrade the air quality in PTAC-equipped spaces without replacing the PTAC unit itself. It is the most cost-effective way to add true HEPA filtration to an existing PTAC system.
Best For
Hotels, motels, extended-stay properties, senior living communities, assisted living facilities, apartment complexes, and individual travelers who want clean, filtered air in PTAC-equipped rooms.
Replacement Filters
The RZ AIRFlow uses replaceable HEPA and active carbon filters for ongoing peak performance. Replacement filters are available separately — see the RZ AIRFlow HEPA Replacement Filter and Active Carbon Filter Kit in our accessories section.
Replace filters regularly for peak 99.97% True HEPA filtration performance.

RZ AIRflow Overview
Watch this overview video to learn more about RZ AIRflow, the world's first PTAC powered air purifier. Used to purify the air in rooms for travel, senior living communities, apartments, hospitals, schools and more - anywhere a PTAC unit is found.
POWERFUL PTAC AIR FLOW MEETS HEPA PURIFICATION
Using the power of the PTAC air, the RZ AIRflow provides continuous purification of rooms within 45 minutes on average.
NO EXTRA POWER, NO EXTRA NOISE - SET IT & FORGET IT INSTALLATION
Set the RZ AIRflow air purifying filter up in minutes by attaching the two active carbon side filters with the center HEPA filter. While the PTAC unit is powered on, the RZ AIRflow will actively purify the room within 45 minutes with no additional power needed and no added noise beyond the PTAC unit.
THE POWER OF THE PTAC - FILTER AIR FROM INSIDE & OUTSIDE
A unique feature of the RZ AIRflow paired with the PTAC unit is it filters and purifies both the air inside the room, as well as the air pulled through the PTAC from outside. This helps filter out common allergens such as pollen and dust as well as smoke and fumes with only minimal impact to the overall unit airflow (5%).
COST EFFECTIVE REPLACEABLE FILTERS - LAST UP TO 6 MONTHS OF CONTINUOUS USE
Costing a maximum of $.24 a day, the RZ AIRflow comes with one HEPA filter + two active carbon filters. Filter replacement options are affordable and help extend the lifetime use of the RZ AIRflow.
*Based on continuous use for 3 years.

You can also view our sizing guide video here: Sizing & Fitting Guide
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. Below are our general guidelines:
20-30 hours of continuous use in heavy dust exposure to things such as; grain bins, off-roading, construction/demolition, etc.
30-40 hours of continuous use in light dust exposure to things such as; grain bins, off-roading, construction/demolition, etc.
50-60 hours of continuous use when protecting against allergens, pollutants, odors, etc.
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.
