Air purifiers are devices that can help improve the quality of indoor air by removing pollutants such as dust, pollen, smoke, odors, and viruses. They can also provide relief for people with allergies, asthma, or other respiratory conditions. But with so many models and features to choose from, how do you find the best air purifier for your needs?

In this article, we will review the top 8 air purifiers of 2023 based on our extensive testing and research at Wirecutter. We will also explain the key factors to consider when buying a wirecutter air purifier, such as size, performance, noise level, maintenance, and cost. Whether you need an air purifier for your bedroom, living room, or office, we have a recommendation for you.

How We Tested

We tested more than 50 air purifiers over the past eight years using a variety of methods and metrics. Here are some of the main aspects we evaluated:

• Clean Air Delivery Rate (CADR): This is a measure of how quickly an air purifier can filter a specific amount of air for three types of pollutants: dust, pollen, and smoke. It is expressed in cubic feet per minute (cfm). The higher the CADR, the more efficient the air purifier is at cleaning the air. URL : https://hitechyinfo.com/wirecutter-air-purifiers/

• Air Changes per Hour (ACH): This is a measure of how many times an air purifier can exchange the entire volume of air in a given room size per hour. It is expressed as a number followed by an x (e.g., 4x). The higher the ACH, the more frequently the air purifier refreshes the air.

• Noise Level: This is a measure of how loud an air purifier is at different fan speeds. It is expressed in decibels (dB). The lower the noise level, the quieter the air purifier is.

• Energy Consumption: This is a measure of how much electricity an air purifier uses at different fan speeds. It is expressed in watts (W). The lower the energy consumption, the more energy-efficient the air purifier is.

• Filter Life and Cost: This is a measure of how long an air purifier’s filters last and how much they cost to replace. It is expressed in months and dollars ($). The longer the filter life and the lower the filter cost, the more economical the air purifier is.

We also considered other factors such as design, ease of use, smart features, warranty, and customer service.
