What air purifier should I buy?

There are many air purifiers available on the market, so it's important to choose one that suits your specific needs. Here are some factors to consider when selecting an air purifier:

• Room size: Choose an air purifier with a coverage area that matches the size of the room where you will be using it. You can check the manufacturer's specifications to determine the recommended room size for the air purifier.
• Type of filter: Look for an air purifier that can capture 99.97% of particles as small as 0.01 microns. Many harmful viruses and bacteria are much smaller than 0.3 microns which is primarily effective at capturing larger particles such as dust, pollen, and pet dander.
• Noise level: If you plan to use the air purifier in a bedroom or other quiet space, consider the noise level of the unit. Look for an air purifier with a low decibel rating, which will operate quietly and not disturb your sleep or activities.
• Energy efficiency: Consider the energy efficiency of the air purifier, as it will be running continuously to purify the air. Look for a unit with low energy consumption relative to its efficiency and size of space it can service.
• Additional features: Some air purifiers may come with additional features such as air quality sensors, automatic shut-off, or remote control. Consider if these features are important to you and if they will be useful in your specific situation.

While there are many air purifiers available in the market, it's important to read reviews and compare different specifications before making a purchase to ensure you find the best air purifier for your needs and budget. `
