The RZ AIRFlow PTAC Air Purifier: The Smarter Indoor Air Quality Solution for Hotels, Senior Living, Assisted Living & Apartments

Across the United States, millions of hotel rooms, senior living suites, assisted living facilities, and apartment units share a common infrastructure challenge: PTAC units that recirculate unfiltered air. Standard PTAC filters are designed to protect the unit's mechanical components — not to filter the air that residents, guests, and patients breathe every day.

The RZ AIRFlow changes that equation. An internationally patent-pending PTAC air purifying system that installs directly into any standard PTAC unit, the RZ AIRFlow delivers True HEPA 99.97% filtration of airborne particulates down to 0.3 microns and an active carbon layer designed to help reduce organic odors — without replacing the PTAC unit, without renovation, and without capital expenditure.

Built by RZ Mask — the company behind 3+ million respiratory protection products sold worldwide since 2011 — the RZ AIRFlow applies over a decade of precision filtration engineering to the spaces where people live, sleep, recover, and are cared for every day.

The Indoor Air Quality Problem No One Is Talking About

According to the U.S. Environmental Protection Agency (EPA), indoor air can be 2 to 5 times more polluted than outdoor air — and Americans spend approximately 90% of their time indoors. For hotel guests, senior living residents, assisted living patients, and apartment dwellers, the quality of indoor air in their specific room or unit is directly tied to the performance of their PTAC system.

The problem: standard PTAC filters capture large debris to protect the unit's mechanical components — not to filter the air you breathe. Fine dust, pollen, mold spores, pet dander, cooking odors, smoke, and organic compounds pass through standard PTAC filters freely and recirculate into living spaces with every heating and cooling cycle.

The RZ AIRFlow is designed to address this gap — delivering True HEPA 99.97% filtration and active carbon organic odor reduction through the existing PTAC infrastructure that's already in place.

RZ AIRFlow for Hotels & Hospitality

The Guest Experience Problem Hotels Can't Ignore

Hotel guests are increasingly aware of indoor air quality — and increasingly vocal about it in reviews. Musty odors, stale air, smoke smell from previous guests, and allergen-triggered discomfort are among the most common guest complaints in hotel reviews. These are not housekeeping problems. They are air quality problems — and they originate in the PTAC unit.

What the RZ AIRFlow Can Help Hotels Achieve

• Reduced organic odor complaints — the active carbon layer is designed to help reduce organic odors from previous guests, smoke, cleaning products, and building materials that accumulate in PTAC systems over time
• Improved guest air quality perception — True HEPA 99.97% filtration helps reduce airborne particulates, dust, and allergens that guests with sensitivities notice immediately upon entering a room
• Differentiated property positioning — hotels that can credibly communicate verified clean air as an amenity have a meaningful differentiator in a competitive market
• No PTAC replacement required — the RZ AIRFlow installs into existing PTAC units without capital expenditure, renovation, or room downtime
• Scalable across properties — the same system works across all standard PTAC units in a property or portfolio

The Cannabis Odor Challenge in Hotels

Cannabis odor in hotel rooms is one of the most persistent and costly guest experience problems in hospitality today. Standard PTAC filters do nothing to address it. The RZ AIRFlow's active carbon layer is designed to help reduce organic odors — including cannabis smoke odors — that accumulate in PTAC systems and recirculate into guest rooms. For hotel operators dealing with this challenge, the RZ AIRFlow offers a practical, cost-effective tool to help address it without room renovation.

RZ AIRFlow for Senior Living & Assisted Living Facilities

Why Indoor Air Quality Matters More in Senior Care

Senior living and assisted living residents spend the majority of their time in their individual rooms or suites — making the air quality in those specific spaces more important than in almost any other residential setting. Older adults, and particularly those with respiratory conditions, cardiovascular concerns, or compromised immune systems, may be more sensitive to airborne particulates, allergens, and organic odors than younger, healthier populations.

The CDC recognizes indoor air quality as an important factor in occupant health and comfort in residential and care settings. For senior living and assisted living operators, providing the best possible indoor air quality in resident rooms is both a care quality issue and a competitive differentiator.

What the RZ AIRFlow Can Help Senior & Assisted Living Facilities Achieve

• Improved room air quality for residents — True HEPA 99.97% filtration is designed to help reduce fine dust, pollen, mold spores, and other airborne particulates from recirculated PTAC air in resident rooms
• Organic odor reduction — the active carbon layer is designed to help reduce organic odors from cleaning products, food, and building materials that can accumulate in PTAC systems in care settings
• No room disruption — installs into existing PTAC units in minutes without moving residents or disrupting room operations
• Scalable across all resident rooms — the same system works across all standard PTAC units in a facility
• Demonstrable care quality investment — a tangible, communicable investment in resident wellbeing that families and prospective residents can understand and appreciate

Fungal Spore Concern in Care Settings

The CDC has highlighted emerging concerns about fungal pathogens in healthcare and long-term care settings. While the RZ AIRFlow is not a medical device and is not designed or certified for infection control, True HEPA 99.97% filtration is designed to capture airborne particulates — including mold spores — at the 0.3 micron level. Facility operators should consult their infection control protocols and clinical advisors for appropriate measures in their specific settings.

RZ AIRFlow for Apartments & Multi-Unit Residential

The Apartment PTAC Problem

The majority of apartments in major urban markets — New York City, Chicago, Los Angeles, Miami, and beyond — use PTAC units as their primary heating and cooling system. Most residents have never thought about what their PTAC unit is doing to their air quality. The answer, without filtration: recirculating fine dust, allergens, cooking odors from neighboring units, and organic compounds from building materials with every cycle.

What the RZ AIRFlow Can Help Apartment Residents & Property Managers Achieve

• Residents — True HEPA 99.97% filtration and active carbon organic odor reduction through their existing PTAC unit, with no landlord permission required and no permanent modification
• Property managers — a cost-effective indoor air quality upgrade that can be offered as an amenity or installed across units without PTAC replacement or renovation
• Allergy and sensitivity sufferers — meaningful filtration of pollen, dust, mold spores, and pet dander from recirculated PTAC air
• Urban residents — reduction of fine urban particulates and organic odors that enter through the PTAC from outside and neighboring units

How the RZ AIRFlow Works: Technical Overview

True HEPA 99.97% Filtration

True HEPA (High Efficiency Particulate Air) filtration is designed to capture 99.97% of airborne particles down to 0.3 microns — the same standard used in hospital-grade air purification systems. This includes fine dust, pollen, mold spores, pet dander, and other fine airborne particulates that standard PTAC filters are not designed to capture.

Active Carbon Layer — Organic Odor Reduction

The active carbon element in the RZ AIRFlow is designed to adsorb organic odor molecules — from cooking, smoke, pets, cleaning products, and building materials — before they enter the living space. This is designed to help reduce organic odors at the source rather than masking them.

Patent-Pending Universal PTAC Fit

The RZ AIRFlow is designed to fit all standard PTAC units — the type found in the vast majority of hotels, senior living facilities, assisted living facilities, and apartment buildings across the United States. Installation requires no tools, no professional service, and no permanent modification to the PTAC unit.

Portable — Room to Room, Property to Property

Unlike fixed air purification systems, the RZ AIRFlow is compact and portable. It can be moved between rooms, taken on travel, or redeployed across a property as needed.
