Control Features
- Optional Ozone-Free Ionizer: The ionizing button activates a feature that emits negatively charged ions into the air that attach to positively charged particles such as dust, pollen, smoke, and bacteria, so they are easier to catch. Some ionizers can emit ozone as a byproduct which can be a lung irritant, but Medify air purifiers do not.

This means that no changes to the settings, power, speed, or special functions like timers or night modes can be made until the lock is deactivated. Sleep mode sets the fan to the lowest speed to make it as quiet as possible.

Things to Consider
- Filter Life: All high-quality air purifiers have filters that need to be occasionally replaced.

Air Purifiers Buyer’s Guide for 2024
When selecting an air purifier, here are 10 important factors to consider to ensure you will be satisfied with your purchase:
- Filter Type: High-Efficiency Particulate Air (HEPA) filters are the standard for effectively capturing particulate matter. True HEPA filters can trap 99.97% of particles that are 0.3 microns in diameter. Some models feature modifications like HEPA 13 or 14, providing even finer filtration. While HEPA 14 is considered the best, it may not be worth the extra initial cost, or additional filter cost.
- Room Size Compatibility: It’s crucial to choose an air purifier that meets or preferably is made to cover more than the size of your room. A model too small won’t effectively clean the air. However, you should consider the additional energy costs of getting a more powerful purifier.
- Control Features: Modern air purifiers come with various control features such as fan speeds, timers, and auto modes. Models with smart features offer added convenience, allowing remote control via apps or voice commands through home assistants like Alexa. This is crucial for some people, but as air purifiers are simple to operate, this feature is not a necessity for most.
- CADR Rating: The Clean Air Delivery Rate (CADR) measures the volume of filtered air an air purifier delivers per minute. This metric helps you understand how quickly and effectively a purifier can clean the air in a specific-sized room. Higher CADR ratings indicate a faster and more capable purifier.
- Design: Consider if you like the design and what your preferred color preference is if you are worried about the air purifier fitting in with the aesthetics of the room in which it will be placed.
- Maintenance and Operating Costs: Consider the longevity and cost of replacement filters as well as the purifier’s energy consumption. Some purifiers also offer washable filters which can be economical and environmentally friendly.
- Noise Level: Especially important in bedrooms or quiet environments, the noise level is something to consider. While it may not be that important to most people, those with kids or conditions where noise may distract them may want to look for the quieter option.
- Customer Ratings: All the air purifiers on this list have a 4.5 out of 5 star rating on Amazon, indicating they are quality products, and most of people who bought them were satisfied with their purchase.
- Warranties: Most air purifiers come with at least a 1-2 year warranty but an air purifier is a big investment for most people. Those worried about the cost of having to replace an air purifier might want to consider one with a longer warranty.
- Certifications: Look for certifications from recognized bodies like CARB, ETL, or Energy Star, which indicate safety, energy efficiency, and environmental friendliness.
