The Surround Air Multi-Tech S4000 utilizes a six stage filtration process to thoroughly remove pollutants from your air.

Poor indoor air quality is considered a nationwide epidemic, and the EPA has issued statements noting the health effects of contaminated air. Smoke, allergens, and microbes can cause irreparable damage to the respiratory system, and long-term exposure to such contaminants can also cause cancer and cardiovascular problems.

In order to address these air quality issues, Surround Air has designed the Multi-Tech S4000 Air Purifier - an advanced air purifier utilizing six of the most effective air purification technologies: HEPA, activated carbon, ionization, Photocatalysis, and UV sterilization. According to government agencies such as the CDC and Department of Homeland Security, HEPA filtration offers the most protection against particulates. However, to extend the life of the other filters, the S4000 begins the purification process with an anti-bacterial pre-filter to remove larger particles. The HEPA filter then removes 99.97% of particulates up to 0.3 microns, and the air is moved through an activated carbon filter where odors and chemicals are trapped. The photocatalyst filter oxidizes any remaining chemicals, bacteria, and odors, and the two UV lamps destroy microorganisms. As an extra step to ensure clean air, the S4000 has an ionizer which safely disperses negative ions to seek out and remove particles.

The S4000 also boasts other unique features such as a timer and independent Ion and UV control, and an ultra-quiet fan with 175 CFM for increased airflow. In fact, in independent studies conducted by the AHAM, the Surround Air S4000 air purifier outperformed more than 80% of all air purifier models tested in terms of dust removal.

Don't sacrifice your health - let the Surround Air Multi-Tech S4000 air purifier help you breathe easier.
