Nailing It: Enhance IAQ and Save Energy in Nail Salons
RenewAire ERVs provide cleaner and healthier indoor air for nail salons while generating major energy savings
Why Nail Salons Are Vulnerable to Poor Indoor Air Quality
Nail salons can contain some of the most polluted indoor air of any type of building. This is due to the numerous chemicals, toxins, vapors, gases, odors, sub-micron particles, and other harmful total volatile organic compounds (VOCs) that are off-gassed from the solutions, creams, sprays, hardeners, glues, and liquids commonly used in nail salons. Not to mention the considerable amount of dust released into the air from constant nail filing.
This continuous and intense build-up of internally generated contaminants makes nail salons especially vulnerable to deficient indoor air quality (IAQ)—a problem that’s magnified by the small spaces salons normally occupy since this leads to higher concentration levels. Deficient IAQ can be extremely harmful to indoor occupants as it causes many short- and long-term health problems, such as respiratory difficulties, skin infections, cancer, lung diseases, and a myriad of reproductive-health complications.
The Impact of VOCs: DBP, Toluene, and Formaldehyde
Specifically, four chemicals that are commonly off-gassed from nail products are the worst offenders in the salons. These are:
- Dibutyl phthalate (DBP): A chemical used to make nail polish and other products pliable that’s banned in the European Union since it can cause developmental defects, reduced sperm counts, and changes in the testes and prostate.
- Toluene: A chemical used to help nail polish glide on smoothly that can impair cognitive and kidney function and harm a developing fetus.
- Formaldehyde: A hardening agent that’s banned in the European Union since it can cause cancer in humans.
- PM2.5: Fine, inhalable particulate matter (PM) with diameters 2.5 micrometers and smaller that can penetrate deeply into lungs and impair respiratory function.
Further, nail salons can suffer from elevated indoor levels of carbon dioxide (CO2), a constituent of exhaled breath, due to high occupant densities. This is troubling as well since the Harvard School of Public Health and Lawrence Berkeley National Laboratory found that CO2 negatively impacts thinking and decision-making at levels commonly found inside all buildings, thus adding to the challenges posed by deficient IAQ for nail salons.
How Balanced Ventilation Enhances Salon Air Quality
The best way to provide cleaner and healthier air inside all buildings, and particularly in nail salons, is through increased and balanced ventilation. By replacing stale indoor air with the same amount of fresh and filtered outdoor air, effective ventilation will achieve high-quality indoor air.
Unlike exhaust-only systems, balanced ventilation exchanges equal parts of air, thus averting pressure fluctuations and preventing outdoor contaminants from being drawn indoors uncontrolled. Plus, balanced ventilation with a push-pull strategy is the best and most economically beneficial way to achieve high ventilation effectiveness to control indoor pollutants.
Awareness of nail salons’ vulnerable state in terms of contaminated indoor air, as well as the effectiveness of increased and balanced ventilation in enhancing IAQ are growing. In fact, New York State passed legislation requiring ventilation systems in nail salons to meet standards outlined in the 2015 International Mechanical Code, which is the most widely used mechanical code in the U.S. These requirements include:
- Fresh outdoor air must be supplied sufficiently to remove all chemicals, vapors, fumes, dust, and other air contaminants from the salon, and these pollutants must all be exhausted safely to the outdoors.
- Ventilation systems must ensure that no exhaust air will be recirculated into the salon or into any other space in the building where the business is operating.
- Specific exhaust systems must be installed at all manicure and pedicure work stations.
Energy-Efficient IAQ Solutions with RenewAire ERVs
Increased and balanced ventilation is the most effective way to enhance IAQ, but conventional systems waste energy and therefore lead to additional costs. What’s the best way to enhance IAQ energy-efficiently and cost-effectively? RenewAire energy recovery ventilators (ERVs) are to replace stale indoor air with fresh and filtered outdoor air. This air is tempered with otherwise-wasted energy with heat and humidity from the outgoing exhaust airstream. This process results in a lower steady-state concentration of the gases and contaminants generated from the inside, as well as less energy used by the HVAC system, thus realizing significant annual energy savings over the long term.
What’s more, RenewAire ERVs are simple to apply, install, maintain, and operate. Consisting of a durable static core, there are no moving parts, and there’s minimal maintenance, thus ensuring ultimate reliability. Further, RenewAire offers an industry-leading 10-year performance warranty so building owners can have peace of mind and be assured that they can downsize capital equipment and save energy every year for the life of the ERV.
Health and Economic Benefits of ERVs for Nail Salons
By installing RenewAire ERVs, nail salons can enhance IAQ while generating major energy savings at the same time. The direct beneficiaries are the indoor occupants who can:
- Experience fewer short- and long-term health problems
- Be able to achieve more coherent thinking and decision-making
- Have fewer sick days, thus boosting productivity and earning potential, which all add up to an improved human condition.
In addition, tenants will appreciate decreased energy costs achieved by RenewAire ERVs and building owners will see an impressive return on investment (ROI) due to lower capital and operating costs, increased lease potential and greater building asset value. In fact, with an average RenewAire ERV internal rate of return of over 45 percent, the net present value of future cash flows on an investment of $6,000 is nearly $40,000 over 15 years. RenewAire ERVs have no increased costs, and the cash flow and ROI are always positive–no matter the metric.
Conclusion: Achieving Sustainable Clean Air
Nail salons are incredibly susceptible to deficient IAQ, which harms health, cognitive function, and productivity, thus impairing wellbeing. To enhance IAQ, while also realizing major energy savings, the solution is increased and balanced ventilation via RenewAire ERVs, which provide cleaner and healthier indoor air energy-efficiently, cost-effectively, and sustainably. This not only improves indoor occupants’ human condition, but it also boosts the bottom line.

Frequently Asked Questions (FAQs)
Why is ventilation so important in nail salons?
+
Nail salons generate high concentrations of volatile organic compounds (VOCs), nail filing dust, chemical vapors, and carbon dioxide (CO₂). Without adequate ventilation, these contaminants accumulate indoors, threatening the long-term health and comfort of both technicians and customers. Continuous airflow is necessary to dilute and exhaust these harmful chemical vapors safely outdoors.
According to the Occupational Safety and Health Administration (OSHA), salon workers are routinely exposed to a complex mixture of airborne chemicals throughout the workday. Without a dedicated ventilation strategy to remove these pollutants at the source, daily chemical off-gassing can lead to severe respiratory issues, skin irritation, and cognitive fatigue.

What ventilation system is best for a nail salon?
+
The most effective setup for a nail salon is a balanced ventilation system that pairs local source-capture exhaust at individual workstations with an energy recovery ventilator (ERV) to continuously supply 100% fresh, filtered outdoor air.
Research conducted by the National Institute for Occupational Safety and Health (NIOSH) shows that source-capture exhaust traps chemical fumes and filing dust directly in the worker’s breathing zone before pollutants can disperse into the room. However, running heavy exhaust without a managed supply creates negative air pressure draft issues. Pairing source-capture exhaust with a RenewAire static-core ERV ensures balanced airflow, bringing in clean outdoor air while recycling up to 70% of the energy from the outgoing exhaust airstream.
Do nail salons need to meet ventilation code requirements?
+
Yes, nail salons are legally required to comply with local building codes, state mechanical standards, and national model codes in order to secure operating permits, maintain business licenses, and pass municipal health inspections.
Building codes across the country have tightened significantly to protect worker safety and public health. For example, regulatory agencies like the New York State Department of State strictly enforce specific mechanical ventilation standards for all licensed nail specialty businesses.
What are the mechanical ventilation code requirements for nail salons?
+
Modern mechanical standards—as outlined in the International Code Council (ICC) CodeNotes for Nail Salon Exhaust Requirements—mandate dedicated source-capture exhaust operating at a minimum of 50 CFM per manicure/pedicure station, continuous 100% outdoor air exchange, and zero recirculation of salon exhaust air into adjacent tenant spaces.
Because mechanical codes prohibit recirculating salon air into other building zones, salon HVAC systems must exhaust 100% of the contaminated indoor air directly outdoors. Exhausting high volumes of conditioned indoor air can increase utility bills. Incorporating an energy recovery ventilator (ERV), like a RenewAire EV Premium M, into the mechanical design satisfies mandatory outdoor air exchange codes while recovering otherwise wasted energy from the exhaust stream to temper incoming fresh air.

How do energy recovery ventilators (ERVs) cut HVAC costs in nail salons?
+
RenewAire ERVs can help lower ventilation energy costs in salons by transferring heat and humidity between the outgoing exhaust air and incoming outdoor fresh air, recovering up to 70% of the energy that would otherwise be wasted.
Because nail salons must operate high-volume exhaust systems to meet building codes, bringing in unconditioned outdoor air severely overworks traditional heating and cooling equipment. As demonstrated in commercial building studies supported by the U.S. Department of Energy (DOE), total enthalpy recovery pre-conditions incoming outdoor air before it reaches the main HVAC coil. This lowers peak demand charges, cuts annual energy consumption, and enables building owners to downsize primary cooling and heating equipment for lower upfront capital costs.
