A few days ago, some media outlets reported that many intermediate rental rooms in Beijing were found to have excessive formaldehyde levels. Most of these rooms were rented out shortly after renovation, with little or no proper ventilation. This issue has raised serious concerns about the health risks faced by tenants who unknowingly move into such environments.
We all know that formaldehyde is extremely harmful to human health. It can cause damage to the immune system, liver, and nervous system, leading to long-term health problems and even reducing life expectancy. Despite the dangers, there are currently no clear national standards for air quality in these types of renovated rooms, leaving the burden of "bad air" on unsuspecting renters.
To address this problem, it's essential to find an effective solution for removing formaldehyde from indoor air. One recommended option is the AO Smith KJ400F-B11 air purifier, which is designed specifically for formaldehyde removal and overall air purification.
This air purifier features a tower-style layered filtration system, where each filter layer plays a specific role in progressively removing pollutants. The filters can be replaced individually, making maintenance simple and efficient.
One key component is the high-efficiency HPEA filter, which meets the American commercial MERV7 standard. It includes a glass fiber skeleton and a dense PP meltblown layer, significantly extending its lifespan. The filter area reaches 3 square meters, effectively capturing fine particles like PM2.5 and PM0.3. In just 30 minutes, it removes over 97.73% of formaldehyde, and within 60 minutes, it eliminates 97.95% of TVOCs. For particles as small as 0.1–0.2 microns, the removal rate exceeds 99.9%, and the PM2.5 concentration at the outlet remains zero.
In terms of durability, the particulate CCM value is 3.3 times the national P4 limit, and the formaldehyde CCM exceeds the new F4 standard. The main and pre-filters are positioned above and below the unit, making replacement easy and user-friendly.
Another standout feature is the patented PM2.5 real-time monitoring technology. It uses both laser and infrared sensors, combining the precision of laser detection with the long-lasting reliability of infrared. The control panel displays real-time data on PM2.5 levels and other important metrics, allowing users to clearly monitor indoor air quality and see the purification effect instantly.
With its advanced filtration and smart monitoring, the AO Smith KJ400F-B11 is a reliable choice for improving air quality in newly renovated spaces, ensuring a safer and healthier living environment.
