What to consider to choose a silent air purifier?

 

There are two main reasons to choose silent air purifier:

CADR value

1. As we know, the larger the CADR value, the better, because the purification speed will be faster and the applicable area will be larger. However, if the area is converted, the calculation formula between the CADR value and the applicable area is: the CADR value is multiplied by (0.07-0.12). At first glance, a silent air purifier with a CADR large enough to cover the area of your home would be enough to clean the whole house. But in fact, because of the walls and furniture and other things in the home, simply rely on a large CADR value air purifier is difficult to effectively purify the entire room. In addition, the large CADR value mentioned by the manufacturer actually refers to the data under the maximum air volume, when the noise value is generally high, and we rarely use the maximum CADR gear in daily life.

Noise indicator

2. Noise is an important indicator of user experience. We all have to go to work, which means turning on air purifiers more often at night. At night, especially when sleeping, we require air purifiers not only to purify effectively and quickly, but also to be quiet. This is like the night bedroom open air conditioning, even if the wind is uniform, large air volume, power saving. But the noise is not good! As mentioned earlier, the air purifier's maximum gear is very noisy.

Of course, there are good products that will be ultra-quiet. Such as the new small air purifier, the Little White Spirit. The CADR value of particulate matter and formaldehyde of Xinyi small White Spirit are 257m3/h and 120m3/h respectively, and it can purify 12m3 in 3 minutes. Importantly, the noise of Xinyi Small White Spirit is only 56.8dB(A) under the maximum air volume. And its noise control ability is amazing, which is rare in the market.

 

Detection of Air Purifier Noise

Moreover, according to the detection conditions. The New Yi little White Elf in the background noise is only 15.3dB(A), the noise of the sleep is as low as 29.5dB(A). What is the concept of this? It's so quiet that professional noise LABS can hardly detect it!

As an aside, the new national standard for air purifiers requires the use of sound power level as a measurement and representation method for noise. But some manufacturers deliberately use sound pressure level in order to make the noise value appear lower. For the same noise indicator, the sound pressure level is much lower than the sound power level. According to the test report of the new yi xiao bai. The sound pressure level noise of the air purifier is only less than 18dB(A).


Quiet Air purifier tip:

A large CADR is important, but noise is also extremely important. The expression method of noise to see clearly, ask clear is sound power level or sound pressure level! It is better to look at the third-party detection report provided when determining the noise index and choose the desired purifier for yourself. And there are some other tips when you are using an air purifier. For example, placing your air purifier at a proper place, you can urgently enhance your air purification at the best level.

what's a good pair of sunglasses for cycling?

  Choosing a good pair of sunglasses for cycling is essential to protect your eyes from harmful UV rays, reduce glare, and enhance visibility while riding. Here are some features to look for when selecting cycling sunglasses: UV protection: Ensure the sunglasses offer 100% UV protection to shield your eyes from both UVA and UVB rays. This protection is crucial to safeguard your eyes from potential sun damage during long rides. Polarized lenses: Polarized lenses reduce glare from reflective surfaces, such as water, pavement, or car windshields. This feature enhances your vision and reduces eye strain, especially when cycling in bright conditions. Wraparound design: Look for sunglasses with a wraparound design or large lenses that provide ample coverage. This design helps to block sunlight and wind from entering around the sides, preventing eye fatigue and improving overall comfort. Lightweight and durable: Choose sunglasses that are lightweight and made from durable materials. This ...

What are the difference between polarized and non polarized sunglasses?

  Polarized vs. non-polarized sunglasses differ in their lens technology and how they handle light. Here are the key differences between the two: Light filtration: Polarized sunglasses have a special filter that blocks horizontally oriented light waves while allowing vertically oriented light waves to pass through. This helps to reduce glare from surfaces like water, snow, and roads. On the other hand, non-polarized sunglasses do not have this specific filter, so they only provide basic protection against bright light without the glare reduction benefits. Glare reduction: The main advantage of polarized sunglasses is their ability to significantly reduce glare, which is intense, reflected light that can cause discomfort and impair visibility. Non-polarized sunglasses can reduce overall brightness but do not have the same level of glare reduction. Outdoor activities: Polarized sunglasses are particularly useful for outdoor activities like boating, fishing, skiing, and driving, wher...

why wear sunglasses when sport?

  Wearing sunglasses during sports activities offers a plethora of benefits that can significantly improve an athlete's performance and safeguard their vision. First and foremost, sunglasses equipped with proper UV protection shield the eyes from harmful ultraviolet rays emitted by the sun. Prolonged exposure to UV rays can lead to serious eye conditions, such as cataracts and macular degeneration, making it essential for athletes to invest in sunglasses that provide 100% UVA and UVB protection. Additionally, sunglasses with polarized lenses are particularly beneficial, as they effectively reduce glare caused by sunlight reflecting off water, snow, sand, or other surfaces. By minimizing glare, polarized sunglasses enhance visibility, allowing athletes to better track moving objects like balls or opponents, leading to improved reaction time and performance on the field. Moreover, certain lens colors, such as amber, brown, or copper, enhance contrast, making it easier for athletes to...
