We’ve found Amazon’s best discounts on air purifiers to combat allergies so you can sleep at night and work during the day without sneezing your head off. Whether it’s for yourself, your family, or your workplace, if you want more relief during the allergy season, these three deals can help you save up to $92.

How long do I run my air purifier?
The Coway Airmega purifier.

In previous guides, we’ve discussed how today’s smart air purifiers work and what specs to look at when getting the right size for your room or house -- like CADR, or Clean Air Delivery Rate. But air purifiers can only cycle through a room’s air when they are turned on … which leads us to another important question: Just how long should you run your air purifier? Can you run it for too long? Don’t worry, we have all the answers.
How long should I run my air purifier?
The air quality inside your home is always changing, and the impact of your air purifier will depend on its size -- especially whether you want to clear up a single room or the whole house. In general, you can run an air purifier for a few hours a day and expect it to give the air in its space a thorough cleaning. If you’re only looking at one smaller room, half an hour to an hour can have the same result. That schedule can give you all the benefits that an air purifier offers without requiring it to be on all the time -- but you’ll want to run it at least once a day for best effect.

Do air purifier settings make a difference when running it?
They do. Most air purifiers have several fan settings that affect how quickly they push air through, in exchange for using more power and making more noise. If you only have a few hours a day to clean the air in your home and would prefer not to leave the purifier on when you are away, turn it to its maximum setting and let it run. Just note that max settings on most air purifiers will be too loud to hold a meeting in the same room.
Is it safe to run an air purifier all the time?
Yes. Air purifiers are generally designed to be run all the time if you prefer to. You can put the purifier on its lowest setting to diminish noise and let it run throughout the day.

Molekule adds an Air Score to its Air Pro purifier
molekule enables air score pro

Molekule, one of the leading manufacturers of air purifers, has announced a new feature for its Air Pro purifiers. This new feature, called the Molekule Air Score, provides an easy-to-understand air quality score that shows users the levels of particles and chemicals in the surrounding air.

Molekule states that the score is combined with one of their new sensors in the Air Pro purifiers. That sensor can capture nearby VOCs (volatile organic compounds like aerosol sprays or preservatives), humidity, and CO2 levels. Then, the sensor uses the data from the air to improve the device's 'Auto Protect' mode, which is what the Air Pro uses to adjust fan speeds automatically.
