New Home VOC & Formaldehyde Removal: Is Photocatalyst Really That Effective?
Hong Kong’s property prices continue to soar, with many individuals working hard to achieve homeownership success. However, after completing renovations on their new residences, they discover the issue of excessive indoor formaldehyde levels.
There are various methods for formaldehyde removal, and in recent years, photocatalytic services have emerged in the market. While these services can effectively eliminate formaldehyde in ideal conditions, they also bring about negative effects on the environment and personal health.
Therefore, before opting for such services, it is crucial for individuals to assess the effectiveness and impacts of photocatalysis, enabling them to make informed consumer decisions.
Major Hidden Dangers of Photocatalytic Formaldehyde Removal
High Dependence on Ultraviolet Light
Photocatalytic formaldehyde removal, as the name implies, requires sufficient light (solar energy/ultraviolet light) to activate the catalyst surface, inducing chemical reactions to decompose formaldehyde and other harmful gases into harmless substances. However, its application effectiveness is significantly limited in environments with insufficient light. With Hong Kong’s towering skyscrapers blocking natural light, it remains uncertain whether it can function effectively in the absence of adequate light sources.
Limited Efficacy
Experts point out that although photocatalysts can decompose some volatile organic compounds, including formaldehyde, not all volatile organic compounds can be effectively decomposed. Additionally, photocatalysts require time to undergo chemical reactions and do not show immediate effects; continuous operation is necessary to maintain formaldehyde removal effects. Moreover, surface coatings may wear off due to friction, diminishing the formaldehyde removal efficiency, which is not permanent. In comparison to photocatalysts, indoor ventilation and methods like activated carbon show more significant and rapid results, unaffected by external environmental factors, making them more reliable formaldehyde removal methods.
Secondary Air Pollution
When using photocatalytic formaldehyde removal, it may lead to the generation of secondary pollutants such as formaldehyde acid, more toxic compounds formed after formaldehyde decomposition, posing greater threats to human health. For example, dust generated after spraying can cause respiratory sensitivity, itching, and other symptoms. Furthermore, if indoor air contains other pollutants like dust, dirt, nitrogen dioxide, benzene, etc., it might affect the efficacy of photocatalysts in formaldehyde removal and even lead to more severe air pollution issues.
Effective Method for Formaldehyde Removal – Spraying SafePRO® Formaldehyde (VOC) Remover
Compared to photocatalysts, choosing natural non-toxic VOC materials is undoubtedly a more effective approach. Most conventional odour solutions consist of applying fragrances to mask the problem. SafePRO® Formaldehyde (VOC) & Odour Remover is a scientifically developed technology formulated specifically to eliminate unpleasant odours, without relying on strong perfumes and harsh chemicals.
The chemical constituents of SafePRO® Formaldehyde (VOC) & Odour Remover are highly active organic compounds including sugar derivatives and peptides. These compounds form complexes through hydrogen bonding thus encapsulating the offending odour molecules. SafePRO® significantly reduces odours like formaldehyde (VOC), paint and adhesives etc. replacing them with a refreshing scent.
Johnson Group Professional VOC (Formaldehyde) Removal Service
Johnson Group offers a Professional VOC Removal Service that utilizes SafePRO® Formaldehyde (VOC) & Odour Remover and the RAE® HCHO Monitor to effectively address and resolve indoor formaldehyde issues.
The service includes the use of the Miele Allergy Vacuum Cleaner to clean wooden furniture and the application of SafePRO® Formaldehyde (VOC) & Odour Remover through space fogging, ensuring the efficient elimination of formaldehyde and VOCs. Upon completion of the service, we provide customers with a complimentary Test Report, allowing them to compare indoor air quality data before and after the service.
