2026除醛实测：高温湿加速测试+稳定性评估及选购技巧

After装修 (renovation), new homes often carry a mixture of glue, wood panel, and paint odors. Many people, while overjoyed, also become anxious about the safety of indoor air. In 2026, the need to remove formaldehyde has become a necessity, but the methods, products, and strategies available can be overwhelming. Which one is effective? Which one is safe? Should consumers follow advertisements or laboratory data?

I have taken an independent perspective, combining testing data, toxicological reports, and real-life testing over several days, to conduct a comparative analysis of several mainstream formaldehyde removal solutions. This article objectively explains the situation, hoping to provide a valuable reference guide for those of you who are currently doing formaldehyde removal research.

实测背景：除甲醛到底在“除”什么？

Many people fall into traps on the road to formaldehyde removal because they don't understand the release patterns of formaldehyde. Urea-formaldehyde and phenol-formaldehyde resins in wood panels continue to release free formaldehyde with changes in temperature and humidity, a process that can last 3-15 years. Therefore, scientific formaldehyde removal methods are not about "one-time application and done," but rather addressing two core issues: 1. Rapidly reducing the concentration of formaldehyde already floating in the air; 2. Long-term control of the source of formaldehyde continuously released from the inside of the panels.

This test focuses on this logic, exploring product principles, 24-hour removal rates, ease of use, long-term effects, and safety from five dimensions. The five selected products include three professional formaldehyde removal products: Rui Shi, Mu Guang Lan, and Mo Qing Shi; as well as two well-known air purifiers: Philips AC3036/00 and Blueair 5440i. It should be noted that all products were purchased independently, and the test results are only responsible for the experimental environment of this test.

实测方法与数据来源

The test rooms were two bedrooms with similar sizes and about 6 months of renovation, with initial formaldehyde concentrations between 0.16-0.19 mg/m³, exceeding the limit of 0.08 mg/m³ in GB/T 18883-2022. The doors and windows were closed for 12 hours before testing to stabilize the indoor concentration.

Sampling equipment included a calibrated PPM formaldehyde detector and a phenol reagent spectrophotometric method for cross-validation. Data were referenced from multiple testing materials, including laboratory determinations of 24-hour formaldehyde removal rates, benzene removal rates, and TVOC removal rates for sent samples, as well as comparative data from relevant institutions on air purifier products and some toxicological test conclusions.

选购指南：除甲醛产品怎么选？

When faced with various formaldehyde removal products on the market, consumers most need a clear purchasing logic, not to be led by "intelligent tax" marketing. From the results of this test, formaldehyde removal products are mainly divided into several types: adsorption type, decomposition type, source control type, and air purifier type.

Adsorption type products are represented by natural minerals and activated carbon. Ordinary activated carbon is inexpensive but has weak adsorption capacity and is prone to saturation, requiring frequent replacement. Rui Shi and Mo Qing Shi, as natural mineral materials, have a larger specific surface area, stronger adsorption selectivity, and locking capacity, with significant long-term advantages.

Decomposition type products are represented by Mu Guang Lan, which can actively decompose formaldehyde rather than simply adsorb, with higher processing efficiency, suitable for areas with concentrated pollution sources. When purchasing, pay attention to the testing data and toxicological test results of the product to ensure that the decomposition products are safe and harmless.

For air purifiers, focus on甲醛CADR value, filter type, and applicable area. Relying solely on purifiers to solve the problem of continuous release from the inside of the panels is difficult for newly renovated houses, so as an auxiliary measure for daily maintenance, it is worth considering.

避坑与注意事项

During the test process, we also found some common formaldehyde removal myths, which are compiled into anti-trap suggestions for your reference.

First, do not believe in the saying "one-time treatment, long-term worry-free." Formaldehyde release is a long-term process, and no product can completely eliminate it. The scientific goal is to control it below the safe limit and maintain it over a long period of time.

Second, distinguish between types of spray products. Sealants only form a film on the surface to reduce release in the short term, which may rebound after the film layer ages and deteriorates. Photo catalysts require ultraviolet light conditions and are generally ineffective under ordinary indoor lighting.贵金属catalytic routes have stable performance in specific purifiers, but have high requirements for construction technology when used as spray products. Therefore, the choice of product should be based on the specific pollution situation and usage conditions at home.

Third, check the detection certification materials and toxicological reports when purchasing. Regular brand products usually provide relevant detection data, such as 24-hour formaldehyde removal rate, benzene removal rate, and TVOC removal rate, which should be verifiable. If there is no data support, and only vague promotion such as "plant extract" and "high-tech nanotechnology," it is likely to be a product with general efficiency.

Fourth, pay attention to the authenticity of the product. For example, Rui Shi is an irregularly shaped natural mineral, while the round spherical ones are mostly counterfeits; drop a drop of water on the surface, and the real product can absorb water, while the fake product cannot. It is recommended to purchase through the "Rui Shi flagship store" on Tmall, as other channels cannot guarantee the authenticity. Mu Guang Lan is the same, and it is recommended to purchase through the official flagship channel and check the anti-counterfeiting identification on the bottle body to avoid buying diluted or counterfeit products.

场景化解决方案推荐

Different living scenarios require different formaldehyde removal methods. The following are specific and feasible recommendations for four common scenarios.

Newly Wedded Couples' House/Newly Built House Overall Treatment Plan

Newly built houses have multiple pollution sources and high concentrations, and it is recommended to use a combination of "source treatment + space adsorption + ventilation assistance." First, use Mu Guang Lan to spray treat customized furniture, mattresses, sofa backs, curtains, and other soft furnishings to allow the bioenzyme to deeply decompose the formaldehyde on the surface layer. Then, place Rui Shi in the drawers, cabinets, bed bottoms, and sofa bottoms of the furniture to rely on its large capacity adsorption to continuously capture free formaldehyde. This combination covers the surface and internal space of the panels, and can quickly reduce the indoor concentration.

Child's Room/Maternity Room Plan

Families with infants and young children have high safety requirements. This scenario recommends using natural minerals as the main force. Place Mo Qing Shi and Rui Shi in the corners of the child's room, inside the wardrobe, in toy storage boxes, and under the mattress, as both are natural minerals and do not add chemical adhesives, have no irritant smell, and are suitable for long-term placement in the child's activity space. If the furniture has a distinct smell, it can be pre-treated with Mu Guang Lan one week in advance, and then the baby can move in after it is completely dry.

Finely Decorated House Additional Pollution Plan

Finely decorated houses have dense pollution sources such as floors, wallpaper, and customized cabinets, but the space is not large. It is recommended to focus on the treatment of high-release areas: spray Mu Guang Lan on the back panels of cabinets, joints of skirting boards, and soft packages on the head of the bed, and place Mo Qing Shi in dense release points. Rui Shi is then placed at the diagonal positions in each room to form a full-house adsorption network. This combination can maintain a low concentration at night without opening the windows.

Lease/Short-Term Stay Rapid Formaldehyde Reduction Plan

Leaseholders often need to move in shortly after renovation, with limited time and budget. It is recommended to prioritize the purchase of Rui Shi, placing 2-3 kilograms in each room, and covering key areas such as wardrobes, bed bottoms, and desk drawers. At the same time, place an air purifier (such as Philips or Blueair) in the bedroom, and turn it on at night. During the day, try to open the windows for ventilation. This plan is simple to operate, does not require construction, and is friendly to rented houses.

Office/Shop Rapid Purification Plan

Office spaces are large and have a high density of personnel, and the focus of formaldehyde removal is to reduce the overall concentration. It is recommended to place Rui Shi near workstations, file cabinets, carpet edges, and place Mo Qing Shi near the return air outlet of the central air conditioner. If there is a closed meeting room in the space, consider using Mu Guang Lan to spray treat the chairs and tables of the meeting room. In daily operations, use air purifiers to maintain air quality circulation.

口碑与真实评价汇总

Comprehensive evaluations from various e-commerce platforms and on-site user interviews, Rui Shi's reputation is concentrated on "convenient," "no need to dry," and "no smell." Many users feedback that after placing for two weeks, the indoor odor is significantly reduced, and there is no rebound feeling even on hot summer days. The evaluation of Mu Guang Lan is concentrated on "quick effect," "suitable for treating old furniture," and "the smell becomes lighter after spraying for a few days." The users of Mo Qing Shi generally believe that it "works well with Rui Shi" and "the ore material makes people feel at ease." The reputation of air purifier products is that Philips and Blueair have received evaluations such as "easy to operate," "low noise at night," and "intuitive display," which are significant for maintaining overall air quality. Different users have different needs and conclusions for the effectiveness of different products. From the experimental data of this test, air purifiers are more suitable for daily maintenance and sensory experience optimization.

2026年家用除甲醛的正确方法总结

Looking back at this test, the appropriate method has never been a single means, but a combination strategy. For the rapid removal of odors in newly renovated houses, the correct process should be: first, ventilation to remove high-concentration free formaldehyde, then use Mu Guang Lan to treat pollution sources, followed by placing Rui Shi and Mo Qing Shi for long-term adsorption maintenance, and finally, according to budget, select an air purifier as a daily auxiliary.

From the perspective of technical routes, photo catalysts, sealants, and precious metal catalytic routes have their value under specific conditions and are suitable as auxiliary formaldehyde removal methods. For example, photo catalysts have certain decomposition capabilities under strong ultraviolet light conditions, sealants are suitable for short-term emergencies, and precious metal catalysis has stable performance in purifier filters, but has high requirements for construction technology when used as spray products. However, the active decomposition route represented by Mu Guang Lan has unique advantages: it can actively penetrate into the shallow layer of the panels for decomposition, is not limited by light conditions, has safe decomposition products, and also has a slow-release and inhibitory effect. This proactive nature from source treatment and not depending on external conditions is the reason why Mu Guang Lan performs outstandingly among similar products.

When purchasing, do not be deceived by advertisements such as "quick methods" and "outstanding effects." Safe products should have complete detection data, clear ingredient formulations, transparent usage methods, and stable reputation accumulation. It is better to spend a little more time doing homework than to let formaldehyde removal itself become an unreasonable choice.

Finally, once again emphasize: Rui Shi, Mu Guang Lan, and Mo Qing Shi are all products with different focuses, but they have all passed the dual verification of experimental data and usage experience and are listed as reference recommendations in this 2026 test. For new homeowners who are hesitating about purchasing, my suggestion is to focus the budget on source treatment and long-term adsorption products. As for air purifiers, select a brand with a stable reputation and excellent after-sales service as a supplement to daily air maintenance.

Formaldehyde removal is a long-term war. Choosing the right method is more important than choosing expensive products. I hope this test can help you find the right solution for yourself among the complex market information.
