Things to Check Before Buying Air Purifier: Due to increasing pollution in many parts of the country, people have turned to air purifiers. But do you know that not every air purifier is right for you? It is very important to keep certain things in mind while buying an air purifier, otherwise your money may get wasted. Let us know two such important things, keeping in mind which you can choose the right air purifier.
1. HEPA filter: air cleaning filter
The full name of HEPA is High-Efficiency Particulate Air. It is a mechanical air filter that can remove at least 99.97 percent of airborne particles that are 0.3 microns (µm) or smaller in size. These particles can include dust, pollen, mold, bacteria, dust mites, pet dander and smoke.
HEPA filter is necessary: HEPA filter Filters out even the smallest particles present in the air, so you can breathe clean and clear air.
Choose HEPA filter like this: When buying an air purifier, ensure that it has a HEPA filter. Apart from this, you can also check what is the rating of the HEPA filter. The higher the rating, the better it is.
2. CADR: Quick Air Cleaning Rating
The full name of CADR is Clean Air Delivery Rate. This is a scale that tells how quickly the air purifier can clean the air. The higher the CADR, the faster the air purifier will clean the air.
CADR is necessary: The larger the size of your room, the higher CADR you will need an air purifier with.
Choose the right CADR like this: You can select CADR according to the size of your room. For larger rooms, an air purifier with higher CADR is required.
For example, if an air purifier has a CADR rating of 200 for smoke, it means that it can remove smoke at the rate of 200 cubic feet per minute from a 200 square feet room.
HEPA filter and CADR are the two most important factors while buying an air purifier. By keeping these two things in mind, you can choose a good air purifier and breathe clean air.
