It is recommended to change the filter once every 3-4 months. However, you may need to change your filter sooner or later depending on how often you use the purifier and the environment in which it is being used. As with any air purifier with a replaceable filter, using Proton Pure in an environment with relatively high pollution may mean you will need to change the filter more often.

When the convenient Filter Change Indicator on the control panel lights up, it means you should check if the filter needs to be cleaned or replaced.

Proton Pure uses a combination of a Level 3 HEPA Filter alongside an Anion Generator to purify the air. The Level 3 HEPA Filter works by forcing air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites, and tobacco smoke. The Anion Generator works alongside the HEPA filter to emit negative ions—charged particles—from the unit that seek out and attach themselves to tiny particles such as dust and bacteria to help the HEPA filter trap more contaminants in your indoor environment, thus making twice as effective.

When plugged into the wall outlet the highest setting, Proton Pure consumes around 25-50 watts per hour. With 24 hours of daily operation, the electricity will be around $3-5 a month or $36-60 annually. If you are concerned about electricity consumption, we recommend setting the unit on a timer and taking full advantage of the cordless feature by doing 8 hours on and 8 hours off.

Proton Pure Air Purifier is only available online and supplies are limited.

Leaving an air purifier on night or day will leave the air in your room cleaner, but will require frequent filter changes.

It's easy, all you need to do is plug it in. Every Proton Pure Air Purifier ships with an easy-to-understand user guide with care instructions for ease of use.

For optimal results, your air purifier should be placed in the room where you spend the most time, or where the air quality is the worst. If your asthma or your allergies keep you awake at night, running your air purifier in your bedroom sounds like the best choice.
