When it comes to improving indoor air quality, many people wonder if an air purifier is worth the investment. The short answer is yes, air purifiers are effective and worth buying. As long as you choose one with the right filters and powerful enough airflow and capacity for your room size, an air purifier can clean the air in an average room in less than half an hour each time you use it. Air purifiers with HEPA filters are capable of eliminating many germs that can include a variety of bacteria, fungi and viruses, as long as there is also a heavy activated carbon filter connected.
These filters are usually in the form of true HEPA (high efficiency particulate air) filters, which are common in most air purifiers. The fan takes that air and moves it through a filter, or several filters, to collect all impurities in the air. It's basically an extremely dense filter that traps microscopic particles (up to about 0.3 microns or millionths of a meter) as they move toward the fibers as a purifier circulates air. The Clean Air Supply Rate (CADR) is an industry-standard rating, based on laboratory testing, that describes the air cleaning effectiveness of an air purifier for particles from 0.10 to 11 microns in size.
This rating helps you choose an air purifier that is right for the room you use it in and your air quality problem. Some models also have permanent air filters that never need to be changed, but need to be washed regularly. Doctors recommend air purifiers and can often be found in hospitals, nurseries, schools, factories, or anywhere that needs air cleaning. Without the harmful allergens in the air, allergies such as coughing, sinuses, itching, dry eyes, and headache will go away and you will live happier and healthier.
Some models even claim to clean countertops and other surfaces, as the treated air is blown out of the vents through your home. In conclusion, investing in an air purifier is worth it if you want to improve your indoor air quality. With a trusted & proven standard like CADR rating, you can buy with confidence knowing that your purchase will be effective in removing harmful particles from your home's atmosphere.
