How Sky Filters clean your air

Your July A/C draws warm air in, expedites the air through the cooling and evaporation process, and pushes cool air back into your home.

The warm air passes through our Air Purifying Sky Filter

Which captures contiminating smoke particles and pollutant debris.

Cleaner air for better sleep.

Studies have shown how better indoor air quality can lead to falling asleep faster and more restful sleep. If you’re using July in your bedroom, you’ll want these for a more relaxed night.

According to “The Association between Air Pollution and Sleep Duration: A Cohort Study of Freshmen at a University in Beijing, China”, published in International Journal of Environmental Research and Public Health, September 11, 2019.
