“It’s a joy to use!” Airvida wearable air purifier recommended
“The Airvida L1 sits so comfortably on the neck, our tester forgot it was there. It’s silent, discrete, and looks almost like a pair of headphones.”
Airvida aims at zero decibel since many people are sensitive to noise, especially at night. However, you would barely notice any noise when Airvida is in operation on the nightstand. Put Airvida right in front of your face to see the effects.
Besides zero decibel, Airvida is super light, which only weights 70g, since there are no fans or filter built in. Moreover, Airvida M1 weights only 20g.
Negative ions VS HEPA filter: How to choose?
HEPA filter is specializes in remove smoke, pollen, dust or bacteria. For people who would be irritated by smell, make sure to notice whether the carbon layer has been added.
When it comes to how to choose a HEPA air purifier, CADR are usually addressed. CADR is how much clear could be emitted in certain time. However, the higher the CADR doesn’t necessarily equal to a good choice. Since with the CADR rises, the noises could be loud.
With the technique of negative ions, Airvida are designed to be carry on with users everywhere. Instead of purifying the whole space, they focus only to the area around user’s nose.
How negative ions purify the air?
Negative ions attach to particles, such as smoke, dust, bacteria, allergens and pollen, making these hazardous airborne particles negatively charged. Thus, the negative charged particles bond together, becoming larger and heavier. Eventually, they fall to the ground. In such way, our noses will be prevented from breathing in these airborne particles.
