Why Allergy-Friendly Design Matters for Hotels The hospitality industry is quickly shifting to meet the demands of health-conscious travelers. More guests are paying attention to the quality of the air, temperature, and overall climate in their rooms. Many experience allergies or sensitivities that can quickly turn an enjoyable stay into a negative one. For hotel managers, understanding the impact of allergens on the guest experience is key to protecting both reputation and revenue. “The global allergy-friendly travel market size reached USD 2.07 billion in 2024, reflecting a rapidly increasing demand for inclusive and safe travel experiences worldwide. The market is projected to grow at a robust CAGR of 9.4% from 2025 to 2033, with the forecasted market size expected to reach USD 4.62 billion by 2033.” — DataIntelo An allergy-friendly environment can strongly influence how guests perceive their hotel stay. A comfortable environment free from dust, strong odors, and stuffy air is likely to make a guest feel their well-being is valued. Meaning, they will be more likely to: By prioritizing clean air and comfort, hotels strengthen trust and stand out in a wellness-focused market. Demonstrating superior IAQ not only differentiates your brand but also supports recognition through green certifications such as LEED. Earning this certification highlights your commitment to sustainability and guest well-being, attracting even more travelers. Every element in a room, from the floor to the curtains, can either trap or reduce allergens. You want the latter. By focusing on materials that are easy to clean, resistant to dust, and low in volatile compounds, hotels can create healthier and more comfortable spaces for guests. Carpets can trap dust, pollen, and pet dander, making it harder to maintain clean air. For an allergy-friendly room, hard-surface flooring such as tile, vinyl, or sealed wood is a better choice. These materials are easier to clean and don’t hold allergens as easily. If carpet is necessary for comfort or noise reduction, use low-pile or hypoallergenic carpet paired with frequent vacuuming to limit allergen buildup. Even after deep cleaning, pet dander can linger in carpets, upholstery, and ventilation systems, triggering allergies long after animals have left. Establishing clear, permanently pet-free zones allows the housekeeping and maintenance teams to focus on consistent allergen control. A pet-free room should follow all the same protocol as an allergy-free room, plus the use of verified dander-removal products and staff training on how to avoid cross-contamination. To prevent dust mites and bacteria from accumulating, use bedding materials like hypoallergenic pillows, mattress covers, and duvets. Hotels should also choose tightly woven fabrics and wash all bedding regularly in hot water to eliminate allergens. Synthetic fillings are often preferable to feathers or down since they resist dust mites and are easier to clean. Many hotels feature two layers of window treatments: a decorative fabric drape and a blackout curtain for light control. Both layers can trap fine particles, particularly when made of heavy, textured, or natural fibers like cotton or linen. To reduce allergen buildup, hotels should opt for machine-washable or easily removable synthetic curtains and regularly deep clean them. Vacuuming both layers weekly with a HEPA-filtered attachment helps prevent dust accumulation, while quarterly laundering or steam cleaning keeps fabrics fresh and mold-free. For long-term maintenance, consider switching to roller shades or washable blackout panels made from non-porous, antimicrobial materials. Hotels should use HEPA-filtered vacuums for all carpeted areas, upholstery, and curtains to capture fine dust, pollen, and dander that standard vacuums may recirculate into the air. When possible, replace traditional cleaning tools with microfiber cloths and mops, as they trap more particles and reduce airborne dust. Cleaning products should be non-toxic, low-VOC, and fragrance-free to prevent respiratory irritation and chemical sensitivity among guests. Training is also key. Housekeeping and engineering staff should learn how to recognize allergen hotspots (like vents, baseboards, and under furniture) and understand safe product usage and ventilation practices. You can align procedures with recognized guidelines from the American Hotel & Lodging Association, so that the property meets high industry benchmarks for health and environmental safety. Guests are quick to notice when a space doesn’t feel fresh, and even quicker to share their experiences online. Reviews mentioning odors or “unclean” air can lower ratings, deter potential bookings, and drive up marketing costs to rebuild trust. A pattern of negative feedback can also reduce repeat visits and weaken brand perception. Poor air quality can even increase housekeeping demands, as dust and contaminants accumulate faster, driving up labor and maintenance costs. Poor air quality often starts with musty odors, stale air, visible dust, or a sense of heaviness in the room. Beyond this, it can also aggravate allergies, trigger respiratory discomfort, and contribute to fatigue or poor sleep. Over time, this leads to a chain reaction that impacts both guest satisfaction and business performance. Developing a hotel-wide air quality strategy ideally begins in the design phase, with built-in air quality sensors and advanced filtration systems integrated into the HVAC network. For many existing properties, a full system overhaul isn’t always feasible right away. The good news is that there are simple steps hotels can take to start improving air quality immediately. Many hotels are now introducing portable Alen air purifiers as part of their in-room wellness offerings. These self contained units provide an easy entry point into air quality programs and can be implemented in several ways: This innovative approach improves guest comfort and confidence, while generating new revenue opportunities, elevating brand reputation, and positioning your property as a leader in wellness-focused hospitality.

Which Type of HVAC System is in Your Hotel?
Hotels use a variety of HVAC systems depending on when the building was constructed and how it was designed. Each system type has its own strengths and limitations, influencing how well it manages airflow, temperature, and air quality throughout the property. Understanding these differences is key to identifying the best strategies for upgrading or maintaining indoor comfort.
Pre-1980s Hotels with AHUs
Hotels built before the 1980s typically rely on central air handling units (AHUs) to circulate and condition indoor air. While useful for large-scale ventilation, these legacy systems can make it difficult to manage allergens and maintain optimal air quality. Modernizing the AHU setup is one of the best ways to improve indoor air, reduce irritants, and create a more comfortable environment for guests.
Air Quality Challenge | Solution | How it Addresses Indoor Air Quality (IAQ) |
| Particulate Filtration | Upgrade to MERV 13 Filters & Install HEPA Air Purifiers | While MERV 13 filters capture smaller particles that older filters miss, adding a HEPA unit provides a powerful second layer of defense, removing 99.9% of irritating particulates from the room. |
| Mold & Microbial Growth | Installation of UV-C Emitters in AHUs | UV-C lights are installed inside the AHU, facing the cooling coils. They continuously sanitize the coils and drain pan, preventing the growth of mold and bio-slime before air is distributed throughout the building. |
| Humidity Control | Integrate a Dedicated Dehumidification Unit | Central chillers aren't always set to the temperature needed for proper dehumidification. A dedicated or updated central system controls humidity to maintain levels below 60%, preventing mold, mildew, and stale air. |
1980s–2000s - Modern Hotels With PTACs or VTACs
Hotels from the 1980s to early 2000s often rely on packaged terminal air conditioners (PTACs) or vertical terminal air conditioners (VTACs) units for reliable room-by-room climate control. Since these systems lack centralized air treatment, the best way to boost air quality is through in-room upgrades that enhance comfort and reduce allergens.
Air Quality Challenge | Solution | How it Addresses IAQ |
| Particulate & Allergen Removal | Install In-Room HEPA Air Purifiers | Since the small PTAC/VTAC units cannot handle thick, high-efficiency filters, a portable (or concealed) HEPA unit is placed in the room. This provides continuous, localized purification of the recirculated air, removing 99.9% of particulates. |
| Stale Air & Odor Removal | Carbon Filtration in In-Room Purifiers | Pairing a HEPA filter with an Activated Carbon filter quickly removes Volatile Organic Compounds (VOCs) and common room odors (e.g., from cleaning products, smoke residue, or food), improving the perceived freshness of the air. |
| Fresh Air Delivery | Upgrade to High-Efficiency Unitary Systems | When replacing an older PTAC/VTAC, choose models with improved outside air intake dampers and better filtration capabilities. While not a full dedicated outdoor air system, modern units offer superior ventilation control compared to their predecessors. |
2005–Present - Hotels With Mixed-Mode HVAC Systems
Modern hotels built after 2005 often feature advanced systems such as variable refrigerant flow (VRF) combined with dedicated outdoor air systems (DOAS). These mixed-mode setups provide an ideal foundation for improving indoor air quality, as they separate temperature control from fresh air delivery and allow for precise, centralized filtration and ventilation.
Air Quality Challenge | Solution | How it Addresses IAQ |
| All-Source Pathogen Control | Install Advanced Ionization or PCO in the DOAS | Since the small PTAC/VTAC units cannot handle thick, high-efficiency filters, a portable (or concealed) HEPA unit is placed in the room. This provides continuous, localized purification of the recirculated air, removing 99.9% of particulates. |
| Air Exchange & Humidity | High-Efficiency Energy Recovery Ventilators (ERVs) | ERVs are essential components of the DOAS that precondition the fresh incoming air using the exhaust air. This transfers heat and moisture, significantly reducing the energy needed to treat the air while ensuring proper, measurable fresh air changes. |
| Individual Unit Cleanliness | Mini-Split UV Lights | While the VRF indoor units are quiet, their coils can still grow mold. Small, cost-effective UV lights are installed inside the hidden VRF fan coil units in the room to keep the coils clean, preventing coil-based odors. |
| Particulate & Allergen Removal | Install In-Room HEPA Air Purifiers | Even in new hotels, a HEPA air purifier is still beneficial because it provides continuous, hyper-localized filtration of recirculated air, capturing fine allergens before the central system can remove them. |
Which Alen Air Purifier Pairs Best With Your Hotel’s System?
When choosing your air purifier keep three factors in mind:
- What type of HVAC system your hotel uses
- The purpose of the space where you will be placing the unit
- Room size
Start by considering your HVAC system (whether it’s centralized, split, or individual room-based) since this determines how air moves and where purification support is most needed. Next, think about the purpose of the space. A quiet guestroom, a busy lobby, and a fitness center each have different air quality demands, from sound levels to odor control and airflow volume. Finally, match the purifier to the room size to ensure the unit’s clean air delivery rate (CADR) can circulate the full air volume with maximum performance.
