Air purifiers for home and office: Our recommendation
Dhaka was just named the world's most polluted city, with the city's air registering 184 on the Air Quality Index (AQI). With the very air we breathe officially being branded as 'unhealthy', air purifiers are quickly becoming a necessity. People who suffer from respiratory problems and seasonal allergies can benefit greatly from using an air purifier.
A purifier for your home or office also provides an extra layer of protection against everything from airborne pollutants to dust particles, pet odours, smoke and even viruses. But with so many types and brands of air-purifying machines available on the market, it can be difficult to discern which air purifier will be the best fit for you. Thus, we have listed some of the top air purifiers for your homes and offices:

Tips for buying an air purifier
If you're new to buying air purifiers, or just want the best value out of your purchase, here are some handy tips to remember.
Pick an air purifier with sufficient coverage capacity taking into consideration the size of the room it's going to be placed in.
Always compare the CADR ratings. Higher the rating, the more effective the purifier at filtering specific pollutants.
Choose an air purifier that's effective at filtering out pollutants specific to your needs (e.g removing pet dander at home or cigarette smoke for the office). Look for HEPA filters, which are the gold standard for indoor air purifiers.
Check the noise level specifications. The lower the decibels, the quieter the air purifier. If you're thinking about the power bills, check the specified power consumption for the air purifier to estimate the ongoing costs.
