Choosing a good air purifier like levoit is a difficult task. Do you really need it? When you received it, how much should it have, what features are important and how effective is it really in cleaning the air? We help you make the right choice for your home.
CADR - What is the air flow?
CADR shows the amount of air passing through the air purifier filter. High-efficiency filters have a high resistance to air flow and make it difficult for air to pass through the filter. This reduces the CADR value.
Therefore, using a more efficient filter can remove the most dangerous particles that are beneficial to your health.
However, the CADR is low because it is very difficult to press air through a better filter.
Requires high efficiency + air flow
You need a good filter for clean air, but you also need a good flow of air. Even if the air purifier does not move enough air, the best filters in the world do not matter.
Air purifier standards are excellent because there is a way to compare air purifiers with CADR particles. It's not perfect, but it's better than nothing.
In general, the higher the number, the better, but CADR's goal is for the air purifier to be able to clean the size of the room. CADR should be considered in relation to the size of the room or house.
CADR is expressed in cubic meters per hour. This is the amount of air that passes through the filter at the maximum fan speed. Note that operating the air purifier at a lower fan speed reduces CADR and testing does not report these values.
A little more about room size.
Consider the approved room size of the air purifier seriously as one of the main selection criteria when buying.
It is recommended that you purchase an air purifier that is certified to effectively clean larger rooms than the ones you use. This allows the air purifier to clean the room air faster and more. As a general rule, buy an air purifier that is at least one-third the size of the room in which it is located.
Example: Suppose you want to use a new air purifier like Levoit LV-H128 in your living room. The dimensions of the room are 25 feet by 20 feet or 500 square feet (square feet). It is recommended to buy a reputable air purifier to clean a slightly larger room (at least a third larger). For example, a certified model for effective cleaning over 750 square feet. This model has a certificate that effectively cleans rooms that are larger than you, so you can clean your room faster and more. This is what you want.
This is true if you buy an air purifier that is approved for a room smaller than the size of the room you want to clean. The air purifier is slower and less frequent because it does not have the approval to effectively clean larger than smaller rooms, but it still cleans the room.
