6 things to know before buying an Air Purifire, including its capacity, utility and rating

As we all know, pollution is increasing everywhere now a days. It has added one more gadget to the house. The trend of having air purifiers is increasing in big cities but people of small cities are adopting them who live in crowded areas. If you are also planning to buy one, then you should definitely know these things….

There are many air purification technologies are in the market. Like the pre-filters you find in your AC. In ionizing purification, air components are ionized by high voltage current. Hepa filters are the real weapon of air purifiers, it traps particulates from fiber sheets. Activation filters out carbon volatile organic compounds (VOCs) and reduces odor. UV or ultraviolet light technology has the power to eliminate the disease causing viruses and bacteria.

Like AC, air purifiers (APs) also have different capacities. As the capacity of AC is measured in tonnes, the capacity of the AP is measured by the "Clean Air Delivery Rate" (CADR). Larger rooms will require more CADR so that the room is clean faster.

The AP used in the home ranges from 30 W to 50 W so it is not much of a cost to run it. The main cost is to change its prefilters, UV lamps, HEPA filters, etc. This has to be done every six months.

Noise ratings are also given in some brands. Extremely quiet APs are also easily found. If there are more users, only quiet models should be selected.

Most APs beep sound to tell when their filters have to be changed. The state of purity of air also suggests that it is clean, bad or more harmful.

Like smart AC, smart APs are also getting in the market. Everything in them is auto. The fan speed is automatically set according to the air quality. They also connect to Wi-Fi and can be operated from the app.
