When it comes to buying an air purifier, there are a few key features to consider. The noise level of the unit is one of the most important factors to consider. The higher the noise level, the more uncomfortable it will be to operate, so make sure that the unit you choose doesn't exceed 40-50 decibels. This will allow you to use the unit at night without disruption.
Additionally, look for certifications such as CARB, AHAM, Energy Star, and UL. These certifications indicate that the unit has been tested and approved for quality and safety. A warranty of at least 1 or 2 years is also a good indication that your money is well spent. When it comes to air purification, AHAM's voluntary certification program provides room size guidelines along with the CADR on its AHAM Verified seal. This ensures that the unit you purchase is capable of removing more than 99% of pollutants from your home or office.
A frequency of four air changes per hour also ensures that the air purifier thoroughly cleans the air and filters as many of the microscopic allergens that trigger symptoms as possible. If you're looking for an air purifier with multiple fan speeds, make sure that it has filters installed. The nominal values will increase as the fan speed increases, but if the air purifier works only with ionization technology or the like, having several fan speeds won't make much of a difference. Electronic air purifiers should be avoided as they can produce ozone. When shopping for an air purifier, look for brands such as Levoit which are widely sold online and at retail stores such as Best Buy, Home Depot, Target, and Walmart. Smart air purifiers come with smart features such as air quality monitoring, Wi-Fi connectivity, and a programmable timer that set them apart from classic models. Finally, consider the type of filter and technology of an air purifier and compare it to your needs before you buy it.
Take note of the air quality in your room with smart air quality monitors to understand the effectiveness of the filtration system.
