How to Choose a Commercial Deodorising Solution: Comparing Bipolar Ionisation, HEPA, Activated Carbon and Aromatherapy

Shopping mall restrooms, office building tea rooms, garbage rooms, smoking areas, hotel rooms, and restaurant back-of-house areas can all face varying degrees of odor problems. For property management companies, cleaning contractors, or venue managers, odours are not just unpleasant, but can also affect customer experience, staff working environment, and venue image.

However, commercial deodorization isn't simply a matter of "placing a machine" and expecting it to solve the problem. Different odor sources require different treatment methods. Odors in the air, floor contamination, bacteria near garbage cans, and grease problems in grease traps or sewers are all different sources of odor.

Therefore, before choosing a commercial deodorizing machine, you should first understand the functions of different technologies, and then determine whether the site needs air deodorization, source treatment, daily cleaning, or odour control for drains, pipelines and grease traps.

 

What factors should be considered before choosing a commercial deodorizing machine?

1. Where is the odor coming from?

The sources of odors vary from place to place. Simply adding fragrances or air purifiers without identifying the source will often have limited effect.

Odour Scenario	Common sources
restrooms/public toilets	Urine smell, ammonia smell, drain smell, toilet odor, musty smell
garbage room	Kitchen waste, garbage residue, sewage accumulation, bacterial growth, and foul odor
Grease trap/sewage drain	Oily wastewater, oilstone accumulation, sewage backflow odor, hydrogen sulfide odor, persistent foul smell
Smoking area	Smoke smell, lingering odors in the air, and insufficient ventilation
Hotel Room	Smoke smell, musty smell, musty smell, residual smell of fabric
Restaurant logistics	Grease trap, drain, kitchen waste, grease wastewater

For example, unpleasant odors in restrooms may originate from urine residue, drain grime, and poor ventilation. For a deeper understanding of the sources of restroom odors, please read further:Why does bathroom odor sometimes come from washing machines? 5 sources and solutions..

 

2. Do people stay in the area for extended periods?

Commercial spaces differ from residential environments. Many places see people spending long periods of time in or working, such as shopping malls, schools, hotels, clubs, office buildings, and public restrooms. Therefore, deodorization solutions must not only be effective but also safe, have acceptable odors, and be suitable for long-term operation.

Some high-intensity odor removal methods may be more suitable for empty spaces, but not necessarily for long-term daily use in occupied environments. For commercial spaces with high foot traffic, zero-ozone, low-irritation, and air treatment solutions suitable for long-term operation would be more appropriate.

For example PureZone Bipolar Ion Air Purifier It can be used as a commercial space air deodorization and purification solution for use in restrooms, near garbage rooms, smoking areas and other scenarios that require long-term air management.

 

3. Is it an air quality issue, or a problem at the source?

Deodorizers primarily deal with odors in the air, but if the source of the odor still exists, the odor may continue to be generated.

In short:

• Unpleasant odors in the air require deodorization and purification.
• The floor, urine stains, and odor from the trash cans require cleaning and deodorization at the source.
• Bacterial growth requires antibacterial treatment and regular cleaning.
• Odors from grease traps and sewers require treatment at the source, including the drainage system and microbial sources.

Therefore, severe commercial odors are usually not solved by a single machine, but require a combination of solutions.

 

Comparison of common commercial deodorization technologies

1. Aromatherapy/Air Fresheners: Suitable for short-term touch-ups, not for addressing the source of the problem.

Aromatherapy diffusers, fragrance diffusers, and air fresheners are convenient to use and can make a space smell more pleasant in a short time. However, most of these products only mask odors with fragrance and may not actually break down odor molecules or eliminate the source of pollution.

If the venue already smells of urine, sewers, garbage, or smoke, the mixture of fragrance and odor may actually become more pungent. For commercial venues, aromatherapy can be used as an odour modifier, but it should not be considered the primary deodorization solution.

 

2. HEPA air purifiers: excellent at particulate filtration, but not specifically for deodorization.

HEPA filters are primarily used to filter airborne particles such as dust, pollen, and some suspended particles. They help improve air cleanliness, but odors are usually gases or volatile molecules, which HEPA filters alone may not be able to effectively remove.

Therefore, if the main problem of the venue is odor, such as urine, smoke, kitchen waste, or sewage, it is not enough to just look at whether there is a HEPA filter. It is also necessary to consider whether to combine it with other deodorization technologies, such as activated carbon, bipolar ionization, or source deodorization solutions.

 

3. Activated carbon: It can absorb odors, but it has a saturation problem.

Activated carbon is commonly found in air purification and deodorization equipment, primarily functioning to adsorb some odors and gaseous pollutants. It is helpful for mild to moderate odors, but activated carbon cannot be used indefinitely.

Once activated carbon becomes saturated, its deodorizing effect will decrease, requiring regular replacement of the filter media. If the odor concentration in the venue is high, there is heavy foot traffic, or the odor source is persistent, activated carbon alone may not be sufficient.

Therefore, when choosing commercial deodorization equipment, one should not only ask "Does it contain activated carbon?", but also understand the amount of activated carbon used, air volume, filter replacement schedule, and whether it needs to be combined with other deodorization technologies.

 

4. Ozone generator: Strong odor removal power, but extra caution is needed in populated environments.

Ozone generators are often used for odor removal in airspace under specific conditions. They have a strong odor removal effect, but attention must be paid to the usage environment, concentration, ventilation, and safety arrangements.

For spaces where people spend extended periods of time, such as shopping malls, schools, hotels, and office buildings, ozone is not suitable as a routine long-term solution. If you are considering ozone generators or related air treatment technologies, it is recommended to first understand their applicable scope and limitations. You can refer to Champion's extended article:Angel or devil? A comprehensive analysis of ozone technology.

 

5. Bipolar ions: Suitable for long-lasting air deodorization in commercial spaces.

Bipolar ion technology is suitable for use in commercial spaces that require long-term air management, such as restrooms, areas near garbage rooms, smoking areas, office buildings, shopping malls, and hotel public spaces.

Unlike simple aromatherapy or filters alone, bipolar ion air deodorization solutions work in conjunction with air circulation and filtration systems to help eliminate odor molecules in the air. This makes it ideal as part of a long-lasting air deodorization solution for high-traffic areas where odors tend to linger.

PureZone Bipolar Ion Air Purifier Combining bipolar ion and HEPA filtration, it can be applied to a variety of commercial spaces to help address air odors and maintain environmental cleanliness.

What kind of matching schemes should be used for different scenarios?

restroom

Unpleasant odors in restrooms are usually not a single problem; they may involve urine smells, ammonia smells, sewer smells, musty smells, and poor ventilation.

Suggested direction:

• PureZone: To remove the smell of urine, ammonia, and musty odor from the air
• 233 C33Used for daily cleaning and deodorizing of hard surfaces.

If there is high traffic in the restroom and unpleasant odors keep recurring, it is recommended to address both the source and the air quality simultaneously, rather than relying solely on aromatherapy or air fresheners.

 

garbage room

Common problems in garbage rooms include kitchen waste odors, garbage can residue, stains on the floor, and bacterial growth. If only the air is treated while ignoring the floor and the garbage cans as the source of the odor, the smell can easily recur.

Suggested direction:

• 233 C33 Multi-Purpose Antomicrobial and Deodorant CleanerUsed for cleaning floors, trash cans, and other hard public surfaces.
• TIC-20Ag Sliver Ions Antibacterial DeodorantAddressing the source of persistent odors

 

Smoking area/hotel room

The problem with smoking areas and hotel rooms is that the smell of smoke lingers in the air, on fabrics, curtains, carpets, or soft furnishings. These odors cannot necessarily be eliminated by simply opening windows or using air fresheners.

Suggested direction:

• Use an air deodorization and purification solution to treat residual smoke odor in the air.
• Combined with deep cleaning of curtains, carpets, fabrics and air conditioning vents
• For hotel or club settings, avoid using overly strong fragrances to prevent negatively impacting the guest experience.

 

Restaurant back-of-house operations / grease trap / sludge drain

Unpleasant odors in restaurant back-of-house areas, shopping mall food courts, central kitchens, and grease traps are not necessarily just air problems, but come from grease, asphalt, sewage, pipes, and the inside of grease traps.

If the odor originates from grease traps, sewers, or greasy wastewater, an air deodorizer alone may not be sufficient. The site needs to treat the grease, wastewater, and odor sources within the pipes and grease traps.

288 PRO-DIGEST Liquid BiologicalMulti-Function Micro-Organism Additive It can be used for grease traps, sewage channels and pipeline source treatment, and is suitable for catering logistics, grease wastewater and pipeline odor management scenarios.

 

Schools/Institutions/Office Buildings

Schools, institutions, and office buildings are spaces where people spend a lot of time, so odor control must not only be effective, but also take into account the users' acceptance and safety.

Suggested direction:

• Priority will be given to solutions that are ozone-free, low-irritant, and capable of long-term operation.
• Avoid over-reliance on strong fragrances
• Combined with daily cleaning, antibacterial and air treatment
• Regularly inspect restrooms, garbage rooms, tea rooms, and high-traffic public spaces.

If the venue involves property management, commercial buildings, schools, or public facilities, you can also refer to Champion's [resources/services]. Property Management Cleaning and Sanitation SolutionsConfigure appropriate cleaning and odor control solutions according to different scenarios.

 

Why do commercial odor control solutions typically require a "combination approach"?

Odors in commercial spaces are usually not from a single source. Restrooms may have the smell of urine, sewers, and ventilation problems at the same time; garbage rooms may have the smell of food waste, bacterial growth, and poor air circulation at the same time; restaurant back-of-house operations may involve grease traps, sewers, and greasy wastewater.

Therefore, truly effective odor management usually requires combining "air deodorization", "source deodorization", "surface cleaning" and "drainage treatment".

We suggest matching according to the scenario:

• PureZone Bipolar Ion Air PurifierAir deodorization and purification
• TIC-20Ag Sliver Ions Antibacterial DeodorantSource-based antibacterial and deodorizing
• 233 C33 Multi-Purpose Antomicrobial and Deodorant CleanerDaily cleaning, antibacterial, and deodorizing.
• 288 PRO-DIGEST Liquid BiologicalMulti-Function Micro-Organism AdditiveGrease traps, sludge treatment and pipeline source control

Before choosing a solution, it is best to first determine the source of the odor, and then decide whether air treatment, source deodorization, surface cleaning, or drain treatment is needed.

 

Five things to consider when purchasing a commercial deodorizing machine

1. Is it suitable for prolonged use in occupied environments?

Commercial spaces are often frequented by people for extended periods, so deodorization equipment should be designed with safety, odor tolerance, and suitability for continuous daily operation in mind.

2. Is it to treat the odor in the air, or just mask the smell?

Some products primarily provide fragrance enhancement and may not address odor molecules or the source of pollution. It's important to understand their true function when purchasing.

3. Is it necessary to replace the filter media or replenish consumables regularly?

HEPA, activated carbon, or other consumable devices all require regular maintenance. Neglecting to replace them may reduce their effectiveness.

4. Is it necessary to cooperate with source cleaning or drainage pipe treatment?

If the odor comes from the ground, garbage cans, urine stains, grease traps, or sewers, an air deodorizer alone may not be enough.

5. Can the supplier provide on-site assessment and after-sales support?

Different venues have different space sizes, ventilation, pedestrian traffic, and odor sources. Ideally, a professional team should first understand the site conditions and then recommend a suitable solution.

 

Commercial Deodorizer FAQ

What are the differences between commercial deodorizers and home air purifiers?

Commercial settings typically have high foot traffic and complex odor sources, requiring more stable long-term operation and more comprehensive source treatment solutions. Home air purifiers may not be able to handle the challenging environments of shopping malls, garbage rooms, public restrooms, or restaurant back-of-house areas.

Can HEPA air purifiers remove odors?

HEPA filters primarily remove particulate matter, such as dust, pollen, and some suspended particles. Their ability to remove odor molecules is limited. To treat odors, they typically need to be used in conjunction with activated carbon, bipolar ion exchange, or other deodorizing technologies.

Is activated carbon always effective at deodorizing?

Activated carbon can absorb some odors, but it can reach saturation. If the odor concentration is high or the venue has high foot traffic, the amount of activated carbon used, the frequency of filter replacement, and whether other technologies are needed need to be considered.

Are ozone generators suitable for commercial settings?

Ozone generators are generally more suitable for air purification under specific conditions and are not recommended for prolonged use in occupied environments. Safety and appropriate usage conditions should be prioritized in occupied spaces such as shopping malls, schools, hotels, and office buildings.

Can odors from grease traps or sewers be removed using deodorizing machines?

Deodorizers primarily address odors in the air. If the odor originates from grease traps, sewers, or pipes, the source should be treated first, such as grease, greasestones, wastewater, and odor-causing bacteria, before combining this with an air deodorization solution.

In summary, commercial deodorizing machines should be selected based on the specific application scenario, not just focusing on a single function.

Commercial deodorizing machines are not necessarily better the more powerful they are, nor does the presence of fragrance indicate effectiveness. Truly effective odor control requires first identifying the source of the odor, and then selecting the appropriate technology.

If the odor comes from the air, consider air deodorization and purification solutions; if it comes from the ground, garbage cans, or bacterial growth, source deodorization and antibacterial cleaning are needed; if the problem comes from grease traps, drains, or pipes, the drains and grease sources should be treated.
